Resale - Private Line Transport (PLT) - GeoMax - V16.0
CenturyLink's retail telecommunication service, GeoMax™ is available for resale by Competitive Local Exchange Carriers (CLECs) to their end-users. Additional information about resale of CenturyLink's retail services can be found in Resale-General.
GeoMax service is a high speed, multi-protocol, fiber optic data transport service. It utilizes Dense Wave Division Multiplexing (DWDM) technology to enable two or more optical signals having different wavelengths to be simultaneously transmitted in the same direction over one strand of fiber. GeoMax service has the ability to support multiple protocols and applications on a single platform. Synchronous Optical Network (SONET) levels are fully supported and include Optical Carrier Level 3, (OC3), OC12 OC48 and OC192.
The components that make up GeoMax are:
- Premise Node - is equipped with one shelf and common equipment. A minimum of two nodes is required per customer application (any mix of Premise or CO Nodes). Each system is capable of supporting up to 32 fully protected or 44 unprotected interfaces. Premise Nodes are CenturyLink provided equipment and are located at customer's location(s).
- Central Office (CO) Node - same as Premise Node, but located in a CenturyLink central office.
- Network Access Channel (NAC) - used to connect CPE at customer premise to a CO Node.
- Additional Wavelengths - May be added to either the premise node or CO node to support up to an additional 44 wavelengths.
- Amplifier Node - Optical amplification provided strengthening of the optical signals to support greater distances that reach beyond normal DWDM optical signals.
- Interoffice Transport Mileage - IOF calculated (per air miles) between serving wire centers for each Node (e.g., A to B, B to C, C to A).
- Ports - can be protected or unprotected
GeoMax supports linear and ring configurations.
There are two linear configurations available:
- Point-to-Point - This configuration is a two-node system that can support up to 8 shelves at each terminal site (32 protected or 64 non-protected customer interfaces).
- Linear Optical Add/Drop Multiplexer (OADM) - This configuration has more than two nodes. It can add or drop a customer signal at any of the sites within the same DWDM Band. Linear OAD supports only unprotected connections.
GeoMax service can connect to the following CenturyLink provided services, and must be made at the CO Node:
- Asynchronous Transfer Mode (ATM)
- Synchronous Service Transport (SST)
- Self Healing Network Service (SHNS)
SST over Geomax is a service option that is available to the customer for the purpose of DS1 and DS3 ports on a customer's Geomax Network. The customer will order both Geomax and SST, and cross connect the SST nodes to the Geomax nodes at the OC-N level. Please refer to CenturyLink Technical Publications 77407 and 77346, for further information and design specifications.
GeoMax is available throughout CenturyLink QC. Technical characteristics, including Network Channel and Network Channel Interface (NC/NCI™) codes, are described in: Technical Publication, GeoMax™, 77407.

|Can combine protected and unprotected on same system||Provides flexibility for multiple customer applications. Offers high Service Level Agreements (SLA) for either option. Regardless of protection option, have 24x7 dedicated, proactive monitoring.|
|Available in point to point or ring architecture||Can provide service through many sites. Combined with features above, GeoMax is a powerful and flexible solution.|
If you are a new CLEC and are ready to do business with CenturyLink, view Getting Started as a Facility-Based CLEC or Getting Started for Resellers. If you are an existing CLEC wishing to amend your Interconnection Agreement or New Customer Questionnaire, additional information is located in the Interconnection Agreement.
An AQCB form must be submitted to the CenturyLink System Design Engineer or the Custom Solutions Engineer for a facilities check by your Account Team / Sales Executives and Service Managers. In the event a facility build is required, additional information regarding the equipment and space requirements at the customer premise are found in the Customer Premise Site Visit Requirements for Fiber Based Services.
Once the AQCB process is completed and approved, the GeoMax™ service requests are submitted using the following Access Service Ordering Guidelines (ASOG) forms:
- Access Service Request
- Transport Request
- Service Address Location Information
Optional ASOG forms could include:
- Additional Circuit Information
- Additional Ring Information Field entry requirements are described in the Access Service Request (ASR) Forms. Service requests should be placed using CenturyLink™ Online Request Application (CORA (AKA QORA)) Graphical User Interface (GUI) or one of the other methods described in CenturyLink ASR Ordering Systems.

Frequently Asked Questions (FAQs)
1. What are the advantages and disadvantages of DWDM
Key advantages of DWDM technology include transparency (i.e., bit rate and protocol independent) making it an ideal optical solution for supporting a customer's multi-protocol applications. It offers scalable bandwidth and quick service provisioning, enabling the offering of bandwidth virtually on demand. Its transparency allows customers to support multiple protocols and applications with a single platform. Customers have the flexibility to pick and choose the protection that fits their specific needs, down to interface or port level.
2. What is included in GeoMax service?
The service includes all the necessary electronics equipment, including the DWDM, fiber facilities, SLAs, and 24/7 monitoring/management service by CenturyLink.
3. What is the SLA for GeoMax?
SLA (Service Level Agreements) consists of the following four parameters. Service Availability, Customer notification, Mean Time to Repair (MTTR) and Installation Guarantee. Please see SLA document for more details.
4. Are there specific distance limitations?
Protocols, including SONET, GigE, etc. can go up to 50km (31 miles) before requiring amplification. If supported by the customer's specific application, optical amplification or regeneration can be deployed to extend the distance.
5. Where is the DWDM equipment physically located?
GeoMax™ DWDM equipment is generally located at customer premises. This allows GeoMax™ to interface directly with customer equipment, avoiding possible distance limitations. However, in some ring configurations GeoMax™ DWDM equipment is located at the customer serving Central Offices (CO).
6. How is the service being managed and monitored?
GeoMax™ service is being managed and monitored remotely by the CenturyLink™ NMS located in Minneapolis, MN. The NMS performs 24/7 proactive network monitoring and management.
7. What are the key customer applications currently supported by
GeoMax? service can support a number of customer applications from data center mainframe connectivity to LAN/WAN internetworking applications. Data center applications can include applications such as data replication, load sharing and Storage Area Networks (SAN). LAN networking such as Gigabit Ethernet and SONET are the other common applications.
8. What is the physical appearance of the "Node"?
Each node consists of a "system" or multiple systems of DWDM boxes. A system is four cabinets, each approximately 7' tall, with a 2.5' square footprint. The box is black metal with smoked glass front.
