CLEC Roles and Responsibilities
Maintenance and Repair Trouble Administration
You are responsible for Maintenance and Repair Trouble Administration for your own end-users, providing them with the means and processes to report troubles associated with their services provided by you. This includes taking all necessary trouble information from them to resolve troubles. CenturyLink will not work directly with your end-users and at no time should you provide them with CenturyLink's contact numbers. CenturyLink will only accept trouble reports from your repair center and we require that you provide us with your contact name and telephone number on all trouble reports in order for us to call if access or additional information is needed.
Maintaining End-user Data
You are responsible for maintaining your end-users' account data including, but not limited to:
- Name, address and telephone number
- Circuit ID information provided by CenturyLink at the time the network element was provisioned
- Your port assignment information
Single Point of Contact
We each must identify a Single Point of Contact (SPOC) to resolve service related issues, and we are both responsible for reviewing and providing updates to SPOC information as required. CenturyLink SPOCs are accessible 24/7. Note: CenturyLink's SPOC numbers should not be given to your end-users nor should you direct them to call any department within CenturyLink. Misdirected calls to CenturyLink from your end-users or a third party will be referred back to you.
- Misdirected Calls
If your end-user calls our Repair Centers, the call is considered misdirected and the caller will be advised to contact their service provider for assistance. CenturyLink will provide the end-user with their service provider's name if available.
The network demarcation point is the point at which CenturyLink's network ends and that of another carrier or end-user begins (e.g., Field Connection Point (FCP), Network Interface Device (NID), InterConnection Distributing Frame (ICDF), jack). See FCC 97-209 and Public Service Commission (PSC) 900 Tariff Section 16 for clarification. To issue an accurate trouble report, you must identify the demarcation point/network interface along with the CenturyLink provided circuit identification and isolate the trouble to the CenturyLink side of the demarcation. The specific location of the end-user premises demarcation point can be determined by working back from your end-user's telephone or station equipment. In accordance with applicable safety and privacy regulations, you may choose to use various inside wire isolation techniques. If you require binding post information to complete your repair or installation work, your technician may call CenturyLink's Repair Department. If available, CenturyLink will provide demarcation binding post information for Designed facilities and building terminal binding post information for POTS facilities through its Repair Department upon request. If binding post information is not available, the existing process for tagging the demarcation point will apply. Should you choose not to dispatch your own technician to find the demarcation point and initiate a trouble report against the network element in question, you will incur a Maintenance of Service Charge. During arepair request you, if CenturyLink dispatches, you can ask that the demarcation point be tagged.
Tagging of Circuits
You may request tagging a demarcation point for any CenturyLink Service. This request can be submitted via your normal channels for submitting repair tickets, through repair call handling groups, or an Electronic Gateway. This type of request is considered Additional Labor. You may be billed an applicable repair charge.
If you report a repair condition and also request tagging on this circuit, and a dispatch to the premises is required, CenturyLink will perform tagging at no charge to CLEC.
If you report a repair condition and also request tagging on other circuits, and a dispatch to the premises is required, we will issue an Assist Test (AT) ticket for each additional circuit tagged. You will be billed for each additional circuit tagged and charges for all tickets will be applied to one ticket. There will be no material charges since all work is being done on the CenturyLink side of the demarcation point.
When you request tagging and no repair condition exists, open an Assist Test (AT) repair ticket. If the repair ticket is opened within thirty (30) days of order completion and the circuit is found tagged, CenturyLink will bill the appropriate repair charge(s). If not tagged, CenturyLink will tag at no charge to you. If the repair ticket is opened after thirty (30) days of order completion, CenturyLink will bill the appropriate repair charge(s).
If you want CenturyLink to move or relocate the demarcation point, you must submit a service request and have an order issued before any work is performed. The technician will not move or relocate the demarcation point until an order has been issued.
General provisioning and installation dispatch information and the associated charges are described in the Provisioning and Installation Overview.
Carrier Facility Assignment (CFA) Cut to Fix
The CFA is a facility from a CenturyLink Central Office that terminates at your location (e.g., central office). If you report trouble on a CFA and it has been isolated to the CenturyLink portion of the CFA, the system or individual channel (time slot) will be repaired or temporarily re-routed to a different channel bank/facility until the original facility can be repaired. You will not need to submit a service request to repair the CFA.
If you request a permanent CFA move when you report trouble, we will make the permanent move, however, you will need to submit a service request. If you are able to obtain an order number or Purchase Order Number (PON) during the permanent move when the Customer Communication Technician (CCT) is online, provide it to that individual. It is your responsibility to submit a service request via an ASR when cutting to another facility. Repair will work the redesign, i.e., permanent move, as they do other circuit redesigns.
If you are unable to get an order number or PON with the CCT online, we will proceed with making the permanent move and hold the trouble ticket as No Access (NA) until you can obtain an order number or PON. If you cannot obtain an order number or PON until the next working day and you want the new CFA cut prior to obtaining an order number or PON, we will make the cut and place the trouble ticket in NA status for 24 hours (work day, Monday - Friday). If you have not contacted us with an order number or PON by the expiration of that NA period, CenturyLink will notify you that we intend to cut the circuit back to its original CFA.
Correcting the Wrong Demarcation on Repair/Moving the Demarcation
If you want CenturyLink to correct or move the demarcation point, you must submit a trouble ticket or a service request and have an order issued before any work is performed. There are primarily three scenarios for correcting/moving the demarcation point. They are as follows:
- Your end-user has requested repair because the demarcation point is not found or the service is not working at the expected location. The technician finds that the installation is correct per the service order and the service is working appropriately at the expected location. If your end-user wants the circuit moved, you must submit a service request and have an order issued before any work will be performed. If your end-user does not want the circuit moved, you will be charged a Maintenance of Service Charge and a dispatch charge.
- Your end-user has requested repair because the demarcation point is not found or the service is not working at the expected location. The technician finds that the installation is correct per the service order and the service is working appropriately at the expected location. The Repair Technician finds that an incorrect address was provided on the original order and that the circuit needs to be re-designed. You will need to cancel the original order and submit a service request for a new order with the correct address.
- Your end-user has requested repair because the demarcation point is not found or the service is not working at the expected location. The technician finds that the installation is not correct per the service order and the service is not working appropriately at the expected location. The Repair Technician will make any changes necessary to make the installation correct per the original order.
Testing Faulty Elements
Before initiating a trouble report to CenturyLink, and to expedite the repair process, you are responsible for identifying the fault and location of the trouble within the Network prior to contacting CenturyLink.
- Test Assurance
At times additional screening and testing may be needed to isolate a trouble when automatic testing is not conclusive. CenturyLink's remote test equipment can isolate a trouble to the network interface unit, customer service unit, or point of interface. If further isolation is required, you may request the dispatch of a CenturyLink technician to your end-user's premises. We will ask that one of your technicians meet our technician at the premises. If this is not possible, a CenturyLink technician will be sent to your end-user's premises on an "Assist Test Ticket." CenturyLink will validate premises access with you and will not contact your end-user without your authorization. Restoring out-of-service conditions take precedence over requests for test assistance. You may request assistance online or by calling and speaking with a Repair Service Attendant (RSA) who will create a trouble report to track testing.
Testing POTS and Other Services at Fault
For services CenturyLink provides, where you do not have the ability to isolate the trouble (e.g., Resale, POTS, LIS), you are not responsible for trouble isolation. In such cases, CenturyLink will perform all testing, trouble isolation and resolution within CenturyLink's Network on your behalf. For POTS you are still responsible for isolating the trouble at the NID. If a CenturyLink technician is dispatched to the end-user's premise and the trouble is not found in the CenturyLink network, a TIC will apply. You must either authorize or deny authorization for TIC when a trouble report is opened. If you do not authorize TIC, a CenturyLink technician will not be dispatched.
Isolating Faulty Element
After you test the circuit to determine the trouble condition and isolate the trouble to CenturyLink's network, you need to determine, to the extent possible, the specific network element experiencing a fault condition. If the trouble is isolated to your side of the demarcation point, you are responsible for repairing the trouble condition. If the trouble is isolated to CenturyLink's side of the demarcation point, CenturyLink will repair the trouble. With your authorization, when CenturyLink dispatches a technician to the end-user's premise, and the technician isolates the trouble to your side of the demarcation point, a Maintenance of Service Charge will be applied. Specific products, i.e., Enhanced Extended Loop (EEL), Unbundled Local Loop, Loop Multiplexer (MUX) Combination (LMC), and Unbundled Dedicated Interoffice Transport (UDIT), provide trouble isolation and testing as a joint process. In this situation, you are responsible for testing and providing trouble isolation results prior to submitting a trouble report to CenturyLink. If you elect not to perform trouble isolation testing, CenturyLink will offer the option of performing the testing on your behalf. If you request optional testing from CenturyLink, you are required to provide your name, telephone number, and authorization to test (either verbally or electronically (via CEMR-MTG)). If you use CEMR-MTG, include the narrative "optional testing authorized" in the comments. See Test Results Information for additional information regarding optional testing.
CenturyLink will provision an Unbundled DS1 Loop to meet American National Standards Institute (ANSI) standards. Depending on the type of installation option you chose, test results may or may not have been provided at time of test and turn up.
If, after acceptance of a DS1 Capable loop, you cannot get the loop to work, you will test to ensure that there are no problems on the customer side of the demarcation point. You will then open a repair ticket and provide test results. CenturyLink will conduct testing and if applicable will contact you to arrange a joint meet; this could include joint testing at the customer's premises. Once testing has been completed, and should CenturyLink find the circuit to function within prescribed transmission parameters, we will mutually share relevant/applicable information pertaining to the circuit; this may include type of CPE, distance and gauge of inside wire, circuit design, end-to-end distance, number of repeaters and distance between repeaters.
If it cannot be determined why the circuit will not work for you, we will alter the dB loss setting where technically feasible, to make the circuit functional. At this point, CenturyLink will bill for the dispatch and the time spent to meet and work on the circuit with you.
Test Results Before Submitting a Trouble Report
If you do not provide test results (except for Resale, POTS, and LIS) when attempting to submit a trouble report and elect not to have CenturyLink perform optional testing on your behalf, CenturyLink will not have enough information to open a valid trouble ticket and therefore will not open one. If you submit your trouble report electronically, and you do not provide test results, nor authorize Optional Testing, CenturyLink will bond back providing you with a 24-hour timeframe to respond with the appropriate information (test results or authorization for optional testing). If you do not respond within the 24-hour, CenturyLink's repair system will automatically close the ticket. You will need to obtain testing information prior to CenturyLink accepting and issuing a valid trouble report. For information regarding test results, acceptable test results, and unacceptable test results; refer to Test Results Information found in the CenturyLink's Roles and Responsibilities section of this PCAT.
You have the right to request reconciliation of trouble reports in order to minimize repeat reports. You can initiate the reconciliation process through your CenturyLink Service Manager.
Third Party Owned Network Element - Repairs
You are responsible for trouble repairs when a third party owns a network element. CenturyLink does not perform trouble maintenance or repairs for third party-owned elements. Depending on your CenturyLink Interconnection Agreement, CenturyLink may provide Third Party assistance on a Time and Material basis. Contact your CenturyLink Service Manager if you need clarification.
Submitting Trouble Reports
The maintenance and repair process begins with the discovery that a service is not functioning properly. This can occur when your end-user realizes they are experiencing poor sound quality, no dial tone or another trouble condition with their telephone service and contacts your customer service organization for assistance or, utilizing your own network testing, monitoring and surveillance tools, you discover a trouble condition.
The core hours of operation for a repair technician are 8 AM to 5 PM local time. Specific hours of operation for repair technicians in a particular area are available when a repair ticket is issued. Note: Some products and services may have CenturyLink "Promise of Service" intervals in which CenturyLink will hold itself to a higher level of service than normal specified guidelines. The CenturyLink "Promise of Service" interval will automatically be available to CenturyLink customers for these products and services. The CenturyLink "Promise of Service" initiative may result in guidelines that reduce the timeframe for maintenance and repair, however, these guidelines are not included in, or supported by, CenturyLink Performance Indicator Definitions (PID) or Performance Assurance Plan (PAP) obligations. To view the list of switch features included in the 8 hour CenturyLink "Promise of Service" click on List of Features - CenturyLink Promise of Service.

Escalations begin with the tester or screener and passes to the duty Supervisor, Manager, Director, and Vice President levels within CenturyLink. For additional information regarding repair escalations, refer to Wholesale Customer Service Repair Escalation List for Residence, Small Business, Medium-Large Business, and Wholesale.
Repairing Faulty Products and Services
When you initiate a trouble report, our center technicians receive and manage the issue through resolution for Designed Services. Your trouble report is routed for testing and trouble isolation where the trouble is initially isolated to one of three general areas:
- Central Office: Includes hardware, wiring, and equipment supporting the network switching or network routing housed inside the Central Office
- Translations: Includes individual line and complex switch translations
- Field: Includes network elements and supporting infrastructure equipment (copper, fiber, NIDs, and electronics) as well as cable outage restoration and proactive maintenance
Technicians in multiple locations across all three general areas may be required to isolate the trouble and restore service. Responsibilities of our repair technicians include:
- Assigning a technician responsible for initial testing on circuits identified in your trouble report (also referred to as a trouble ticket) and isolating trouble
- Routing your report for dispatch to Central Office, Translations, and/or Field Technicians as applicable
- Escalating your report internally until a resource is assigned or progress made
- Performing tests to verify service restoration
- Coordinating cooperative testing
- Facilitating test result handoff activity and restoration concurrence
- Assigning resolution codes prior to closing your report
No Access (Designed Services only)
When a CenturyLink Technician is dispatched at your request, they may encounter a No Access situation that prevents repairing the trouble. No Access situations include:
- Your technician or vendor not available for testing or trouble resolution
- No circuit access
No premises access Exception: When Optional Testing is approved by the customer of record, Stop Time will apply to the trouble ticket while testing is performed. This stop time will not delay the progress of the trouble ticket through the repair process, but it will account for the time the customer of record would have spent performing this testing.
If a No Access situation occurs, trouble resolution is delayed and additional dispatching charges may apply.
When a trouble ticket is received from you for unbundled services, the Repair CCT will validate the circuit notes for the installed circuit and identify from those notes whether there is a "Y" or "N" associated with the "NIU ACCESS (Y/N)" field. This information should have also been Emailed or given verbally to you at the time of installation:
- If the Network Interface Unit (NIU) Access field is marked with a "Y", CenturyLink should have access to the NIU without assistance from you or the end-user. CenturyLink technicians will review this information with the customer of record via a phone call or electronic communication during the initial testing step of the trouble ticket process to determine whether there have been any changes since the service was installed or the last time is was repaired. If the NIU ACCESS field is marked with a "Y" and dispatch is authorized, we will proceed with dispatching a technician.
- If the NIU Access field is marked with a "N", it indicates CenturyLink does not have access to the NIU without assistance from you or the end-user. CenturyLink technicians will review this information with the customer of record via a phone call or electronic communication during the initial testing step of the trouble ticket process to determine whether there have been any changes since the service was installed or the last time is was repaired. We will proceed with testing and dispatch based on this information and the entry of the trouble ticket. (Note: electronically submitted trouble reports automatically authorize dispatch and intrusive testing. For manually submitted trouble reports, authorization to test includes authorization to dispatch.)
- If the circuit notes do not indicate the NIU ACCESS status, the CCT will update the circuit notes for future reference based on findings during this repair visit.
- If, after testing remotely from the center; a central office; or another access point, it is determined that access is required to repair the circuit and access is not available and you have been informed of the no access situation, NA or stop time will apply until access is provided.
- After hours, i.e., outside standard business hours, CenturyLink will not dispatch to the last testable point in a circuit if isolation can be obtained via remote testing. If, after isolation testing (either remotely from a repair center; a central office; or another access point) it is determined that access is required to repair the circuit and access is not available and you have been informed of the no access situation, NA or stop time will apply until access is provided. If testing indicates that the problem is in the CenturyLink network and end-user premise access is not required to repair the circuit, NA or stop time will not apply.
- When you enter a trouble ticket or a CenturyLink representative contacts you, access information will be validated. Examples of contacts that include information we will ask you to provide are as follows:
- Verified access hours with my customer to be 800 to 1600. After that time there will be no access to the communication room where all equipment including CenturyLink's is located.
- Access hours for the building are, 900 to 1700; however, the communication closet is outside of the building requiring contact with the guard who is at gate 7X24.
- Access to the customer communication cage is 900 to 1600. Building access is 800 to 1700 and for immediate access to the cage call xxx-yyy-wwww number.
Out of Hours Dispatch
While CenturyLink's Maintenance and Repair Centers operate 24/7 not all functions and locations are covered 24/7. In major metropolitan areas, where technicians are on duty around the clock, CenturyLink dispatches as if the request was received during normal business hours and tests circuits to the last Central Office where a technician is available. CenturyLink always calls out technicians in life threatening, fire, national security, or other emergency situations. If an out-of-service condition exists that cannot wait until normal business hours for resolution, in an area where CenturyLink's technicians are not available 24/7, CenturyLink will determine the necessity to dispatch and/or call out a technician when the trouble is isolated to a non-staffed Central Office and there is access to the premises. Exceptions may occur in the event of Central Office conversions, system outages, severe weather conditions, or during emergency preparedness situations.
Providing Trouble Report Status Updates
CenturyLink provides two ways to check the status of your trouble reports:
- With CenturyLink's CEMR-MTG System you can view trouble reports, status updates and messages posted by our technicians from your own computer.
- For Trouble Type Abbreviations and Descriptions for Designed UNE and Complex as well as Non-Design POTS and Non-Complex Products and Services refer to our CEMR-MTG On-line Help.
- Or, contact the Wholesale Repair Center for Designed Products and Services or the RCHC for Non-Designed Products and Services to request a status update. If the RSA does not have current information, they will contact the appropriate tester to update you.
Closing Your Trouble Report
When your Designed service is restored to CenturyLink's last point of presence or demarcation point, the Maintenance Control Office (MCO) CCT will contact you to coordinate cooperative testing, obtain restoration concurrence, and provide test results. After obtaining your approval to close your trouble report, the MCO CCT will assign trouble codes and close the trouble report. You can view your closed trouble reports via the history function in CEMR-MTG.
When your Non-Designed service is restored, CenturyLink assigns disposition and cause codes, closes the trouble ticket, and notifies you that the trouble has been resolved. Trouble tickets that are received by CenturyLink electronically, via existing functionality in CEMR-MTG/ MTG, will be closed electronically. You can view your closed trouble reports via the history function in CEMR-MTG. If a trouble ticket was opened via a phone call to the CenturyLink Repair center, CenturyLink will assign disposition and cause codes, close the trouble ticket, and notify you via a phone call that the trouble has been resolved.
CenturyLink Designed Services Trouble Ticket Codes and CenturyLink Non-Designed Disposition & Cause Codes
Information provided in the following documents describes the various trouble reporting codes for designed and non-designed services and their specific definition.
Designed Services Trouble Codes describe the type of trouble encountered.
Non-Designed Services Disposition and Cause Codes identify the reason for service problems. Disposition Codes indicate the action taken to clear the reported trouble, while Cause Codes indicate why.
Test Results Information describes acceptable network test results, unacceptable test results, and other related information.
Additional Maintenance and Repair Activities
CenturyLink follows established FCC guidelines for restoration priorities related to:
- Major Network Outages: Switch, Interoffice facility, or Major cable failures that could be the result of cable cuts or switch problems
- Major Disasters: Natural disasters such as floods, fires, bomb threats, hazardous waste, and tornados
Major Outage Notification
CenturyLink offers an automatic Major Outage Notification. Contact your CenturyLink Service Manager if you have questions or would like to learn more about the automatic notification process.
If you choose to receive CenturyLink's automatic notifications, you will be notified of certain reportable events in our network that may be service affecting. Notifications are sent via Internet e-mail or facsimile simultaneously with our internal event notification usually within 30 minutes after the CenturyLink work center determines a reportable event has occurred, even if the service problem is already resolved. Examples of reportable events are:
- 911 - Any disruption of 911 services regardless of duration.
- Inter Office Facility (IOF)/Transport Failure.
- One or more T3s for 30 minutes or more.
- One or more T3s supporting TSP Defense or Federal Aviation Administration (FAA) Government critical circuits for 15 minutes or more.
- Switch - Total switch failure for two minutes or more or partial switch failure involving 5000 or more lines for 30 minutes or more.
- Signaling - Signaling System 7 (SS7) node isolation of five minutes or more. Switching Transfer Point (STP) or Service Control Point (SCP) down situations for two hours or more.
- Power - Major service interruption as a result of a power failure.
- Fire - Major service interruption as a result of a fire.
- A failure resulting in 25 or more initial end-user reports.
If you choose not to receive automatic notifications, our RSA will provide information of major outages only in conjunction with an active trouble report. With the exception of certain proprietary information, CenturyLink uses the same thresholds and processes for external notification as it does for internal purposes. Service restoration is non-discriminatory and accomplished as quickly as possible according to CenturyLink and/or industry standards.
CenturyLink complies with established federal and state requirements providing network disaster recovery planning at both the state and national levels. Functional exercises are conducted to audit our proficiency at managing the unique communications requirements associated with catastrophic disasters and recovery events. During disaster recovery exercises, CenturyLink's NROC is responsible for notifying your operations center to obtain input and/or cooperation from you. FCC regulations require that all Telecommunication Organizations comply with any applicable federal and state requirements concerning disaster recovery exercises, with us each notifying the other prior to performing these exercises.
Chronic Service Problems (Designed and Non-Designed)
Services having repeated, unresolved service issues may be designated a chronic service problem if the following conditions occur:
- The circuit has had at least three trouble reports in a rolling 30 days
- The circuit has similar, repeated test results on two or more trouble reports
- Trouble on the circuit often clears during testing
CenturyLink's Maintenance and Repair Technicians focus on resolving chronic service problems by:
- Analyzing chronic reports for trends
- Determining root causes
- Taking ownership of the trouble report until service is restored
- Assisting or calling upon internal and/or external experts
If you feel a circuit has a chronic service problem and requires special attention, note the situation on the trouble report you submit or bring it to the attention of the RSA who creates your report. Once our Maintenance and Repair Technician completes the repair, clearing the chronic trouble, CenturyLink will maintain the chronic trouble ticket in "Pending Close" status until you accept the trouble as resolved.
Monitoring Network Equipment
CenturyLink's NROC monitors and maintains our facilities focusing on network integrity, reliability, availability, and quality. Some functions include:
- Call gap management
- Disaster recovery planning at both the state and national levels
- Network traffic management
- Notification of mass calling events
- Operations information control
- Signaling network control
- Tier II network surveillance of CenturyLink's network to proactively monitor our network identifying and resolving issues as they occur
CenturyLink offers surveillance or alarm detection capabilities with Interconnect products and services. Contact your CenturyLink Service Manager if you need additional information.
CenturyLink will work cooperatively with you to determine reasonable notification requirements of service-affecting activities that may occur in normal operation of our business. Such activities may include, but are not limited to, equipment or facilities additions, removals or rearrangements, routine preventative maintenance, and major switching machine change-out. Generally, such activities may affect many services. No specific advance notification period is applicable to all service activities.
Preventive Maintenance Windows
CenturyLink generally performs proactive maintenance activities during "off hours" with maintenance windows between:
- 10:00 PM through 6:00 AM Monday through Friday
- Saturday 10:00 PM through Monday 6:00 AM
NOTE: If 911 service is impacted, the following maintenance windows are used:
- Tuesday through Thursday, 3:00 AM - 6:00 AM Applicable when 50% or more of a 911 trunk group is affected and/or switch translations work is involved. A representative from the affected Public Safety Answering Point (PSAP) must provide approval via the CenturyLink Center for 911 Customer Service.
- Monday through Thursday, 10:00 PM to 6:00 AM Applicable for all other activity when less than 50% of a 911 trunk group is involved. A representative from the affected PSAP must provide approval via the CenturyLink Center for 911 Customer Service.
Switch, transport, or power activities that have the potential to impact customer service are scheduled during a maintenance window except as described below. Maintenance Window activities may include:
- Repairing equipment that has a high impact on customer service
- Modifying hardware or software
- Installing new equipment that involves the following:
- Contact or integration with existing equipment or infrastructure and high impact to customer service
- Maintaining 911 service (Monday through Thursday from 10:00 PM to 6:00 AM)
Proactive loop maintenance for switched-based Non-Designed Services includes Automatic Line Tests (ALIT) which are performed nightly between 9:00 PM and 6:00 AM and MLT performed between 8:00 PM and 4:00 AM after all New (N) or Transfer (T) service order activity. This is also applicable to repair activity involving a dispatch to the field. A dispatch to your end-user's premises may result from these tests.
Non-Maintenance Window Activities may include:
- Repairing equipment to restore interrupted service
- Maintaining equipment associated with the ability to provide
service, equipment may involve the following:
- Communication links
- Operational Support Systems
- Surveillance equipment
- Working on routine tasks that do not jeopardize service
- Installing new equipment under the following conditions:
- No contact with existing equipment or infrastructure
- No integration with existing equipment or infrastructure
- No impact to customer service exists
- CenturyLink will perform maintenance activity on CenturyLink Commercial Broadband Services Remote Equipment Terminals specifically to augment network bandwidth and implement hardware and software upgrades between the remote terminal location and the associated Central Office as needed.
While we normally perform major switch maintenance during the above maintenance windows, there will be occasions where this will not be possible. CenturyLink will provide you notification of any and all maintenance activities that may impact your ordering practices such as embargoes, moratoriums, or quiet periods in substantially the same time and manner as we provide this information to ourselves, our end-users, our affiliates, and any other party.
Major Switch Maintenance
Major switch maintenance activities include switch conversions, switch generic software upgrades and switch equipment additions.
Switch conversions typically require service order embargoes to ensure seamless transition from the old to the new switch. An embargo is a period of time prior to and after the conversion date where trunk connections into the switch are frozen; no trunk related orders, with the exception of conversion orders, will be accepted or provisioned. Embargos for trunk-side facilities extend from 30 days before the conversion date until five days after the conversion.
Line side orders are also impacted by switch conversions. With the exception of disconnect orders, non-switch related billing and records orders, and emergency orders, no service orders may be completed from five days before until two days after the conversion date; referred to as the quiet period. Disconnect orders are the only orders accepted during the quiet period and will be completed after the quiet period expires.
Planned conversions, including embargo periods, and generic software upgrades in CenturyLink's switches are posted on the InterCONNect (ICONN) database containing Local Exchange Routing Guide Information.
