Metro Ethernet Service is a flexible, easy-to-use, transport service that uses established Ethernet transport technology. Metro Ethernet allows customers to connect multiple enterprise locations within a service area using native Ethernet protocol. Metro Ethernet supports transmission speeds as low as 1 Mbps and up to 10 Gbps in increments of 10 Mbps from 10 to 100 Mbps, 100 Mbps from 100 to 1,000 Mbps and 1 Gbps from 1 Gbps to 10 Gbps. This allows for flexible growth and permits the customer to choose a bandwidth profile that fits their real traffic needs. 10 Gbps Ports and Bandwidth profiles above 1 Gbps are available on an ICB basis where facilities and capacity exist to meet the request.
The components that make up the Metro Ethernet service are:
- Network Interface (NI): The point that your end-user’s data transmission enters the network that supports Metro Ethernet. It is the point of interconnection between CenturyLink’s communication facility and your end-users terminal equipment.
- Access Link: A Metro Ethernet Access Link connects a customer facility at the NI to an Ethernet port on the Metro Ethernet network with a standard optical or copper connection.
- Metro Ethernet Port: Metro Ethernet Port is an Ethernet port that is the physical entry point to the shared Metro Ethernet Network. Ethernet Virtual Connections (EVCs) or Operator Virtual Connections (OVCs), originate and terminate on a Metro Ethernet Port. Customers may choose to connect to a 10/100, 1,000Mbps or 10 Gbps port on the Company network
Bandwidth Profile: The Bandwidth Profile is bandwidth provisioned over the
Metro Ethernet Port.

Bandwidth Profile Options - Customer Premises, Central Office, Ethernet with Extended Transport (EwET) Bandwidths, and ICO NNI (ICO Trunking Arrangement)
ICO NNI (ICO Trunking Arrangement)
ICO NNI MOE supports transmission speeds as low as 1 Mbps and up to 1 Gbps in increments of 10 Mbps and in increments of 100 Mbps.
ICO NNI (ICO Trunking Arrangement) Bandwidth Profile
In some cases, the Company and another Incumbent Local Exchange Carrier (ILEC also referred to as an Independent Company or ICO) may agree to jointly provide MOE Service where such service will be provided to locations in both the Company’s and the ICO’s serving territories. In such cases, the Company and ICO may mutually agree to meet at a location (i.e., the Company designated point of interconnection with the LATA or equivalent area) utilizing facilities suitable for delivery of MOE Service. The rates and charges for ICO NNI are applicable to the Company provided portion of the service. The Company is responsible for the ordering, provisioning, billing and maintenance of MOE up to the point of interconnection within the LATA or equivalent area. The ICO NNI Arrangement provides a shared trunk connection from the MOE Switch to the Company designated point of interconnection within the LATA or equivalent area that is then connected to the ICO MOE Switch, for purposes of providing multiple Ethernet Virtual Connections (EVCs) for the same or different customers over this shared facility. The ICO NNI Bandwidth Profile charge is applied to each EVC that is transported on the ICO NNI Trunking Arrangement.
- All ports must be EVC rate limited
- CoS entries on the ASR require one LREF line for each option ordered.
- SM or SP ports can only have either QoS or CoS they cannot have both on the same port
- No oversubscription (EVC/OVC bandwidth cannot exceed total ENNI/UNI bandwidth ).
- CoS is ordered, provisioned and billed on an EVC or OVC.
- The CoS level is specified for each terminating point on an EVC or OVC.
- If a customer has multiple EVCs or OVCs terminating to a SM, SP or ENNI port the CoS MRC is billed for each EVC OVC as outlined in 8 below.
- The MRC for the CoS level is billed for each terminating point of and EVC or OVC (i.e. a 2 point EVC or OVC will have two CoS MRCs billed for that EVC or OVC, a 3 point EVC or OVC will have 3 CoS MRCs billed)
- CoS is available as either a Single CoS model for all members of the EVC/OVC or as a 3 CoS model for all members of an EVC/OVC. If a Single CoS is selected each member can have only 1 CoS specified, each member must have the same single CoS. If a 3 CoS model is selected each member of the EVC/OVC must have 3 CoS values selected, the values for each member can be the same or different values but you must have at least 1Mbps of each CoS on each member.
Committed Information Rate (CIR) Class of Service offers three (3) class options ordered on a per Mbps basis. CIR bandwidths include 1 Mbps through 10 Mbps in 1 Mbps increments, 10 through 100 Mbps options in 10 Mbps increments and 100 Mbps through 1000 Mbps in 100 Mbps options. CIR Bandwidths greater than 1000 Mbps or in increments not provided above are available in an individual case basis (ICB).
Class of Service defines performance characteristics of the network that manages business applications designating with the following classes:
- Real Time: Supports enterprise applications with the highest prioritization that require low frame delay, minimal frame loss and requires low jitter. Applications include voice, video and Telepresence.
- Guaranteed Data: Supports high priority enterprise applications with tolerance for frame delay, frame loss and jitter. Applications include interactive services such as web conferencing, CCTV, video and voice.
- Business Class: Supports enterprise data applications with greater tolerance for frame delay, frame loss and jitter. Because Business Class is the baseline class for serving Metro Ethernet, there are no additional charges for associated CIR bandwidth. Ordering procedures for Business Class is assigned for remaining CIR within the Bandwidth Profile.
Four (4) Class Quality of Service Template
CenturyLink Quality of Service for Metro Ethernet (QoS) will allow customers to prioritize their traffic in four classes of service. The four different levels are Priority 1, Priority 2, Priority 3 and Priority 4. Together, they allow customers to match the correct level to their applications.
In all Quality of Service options, at least 3 Mbps or 5 Mbps of the Bandwidth Profile will be Priority 1 traffic. Priority 1 traffic is ordered in 3 Mbps or 5 Mbps increments and customers may order multiple increments of Quality of Service at monthly and Pricing Plan rates. The 3 Mbps increment of Priority 1 traffic option is only available for 3 Mbps, 5 Mbps, and 7 Mbps Bandwidth Profiles. The 5 Mbps increment of Priority traffic is available for 5 Mbps Bandwidth Profiles and higher. Each individual Quality of Service Priority 1 increment reserves either 3 Mbps or 5 Mbps of the Bandwidth Profile for Priority 1 traffic. For example: if a customer orders 4 increments of 5 Mbps of Quality of Service, the customer would receive 20 Mbps of the Bandwidth Profile for Priority 1 traffic.
In addition to the Priority 1 traffic, Priorities 2, 3 and 4 traffic percentage levels are specified for the remainder of the Bandwidth Profile. CenturyLink offers eight templates (Template 1 through Template 8), to allocate the P2 through P4 traffic. The amount of P2 to P4 traffic will equal the bandwidth profile, minus the amount of P1 traffic.
A Service Level Availability (SLA) is provided for Priority 1 traffic and a credit will apply should CenturyLink fail to meet the SLA.
Multiple Ethernet Virtual Circuits (EVCs) or Operator Virtual Connections (OVCs)
Each port provided by CenturyLink comes standard with the capability to provide one EVC or OVC (based on the type of ports connected, an External Network to Network Interface (ENNI) has OVCs instead of EVCs). Customers may order more than one EVC or OVC per port. For each additional EVC or OVC, CenturyLink will bill a Multiple EVC/OVC charge.
Metro Optical Ethernet Protect Routing
Protect Routing provides a separate facility path for the protection system between the Serving Wire Center and the Company Point of Termination. In the event that the working facility or the service performance becomes impaired, the facility automatically switches to the service protect path in order to maintain a near continuous flow of information between locations.
Protect routing comes with a service guarantee, and a credit will apply should CenturyLink fail to meet the service guarantee.
Central Office Bandwidth Profile
This Metro Ethernet offering originates and terminates in the same central office for use with Synchronous Service Transport (SST) , GeoMax and Self-Healing Network Service (SHNS) Ethernet Ports. This Bandwidth Profile can also be used for collocation. Central Office Bandwidth Profile will support transmission speeds of 100 Mbps, 600 Mbps, and 1,000 Mbps.

See Technical Publication, CenturyLink Metro Optical Ethernet, 77411 - Chapter 2., for more specific information on Logical Port Attributes.
Rate Limiting the Bandwidth
CenturyLink complies with Metro Ethernet Forum (MEF) technical specifications which allow for bandwidth profiles to be applied (rate-limited) at one of three places in the overall architecture.
- Ingress to the UNI -- This type of bandwidth specification is handled using the UNI NC codes. The entire bandwidth profile of the UNI is allowed for the EVC/OVC. Uses the ES field on the ASR and the PROFI if QoS is being ordered on the UNI.
- For the EVC ASR, the following ASOG rule applies to the BDW field: Bandwidth specified at the UNI level = "UNI".
- Ingress to the EVC -- Individual EVCs/OVCs (one or more) associated to a UNI have their own ingress bandwidth profiles applied. For example, 100 Mpbs UNI with one EVC/OVC @ 50 Mbps and another EVC/OVC @ 15 Mbps. This type of specification can be handled using the BDW fields on the LOS portion of the ASOG EVC form. If no QOS option is being ordered, specify “DEFAULT” in the LOS field, and indicate the bandwidth for the EVC/OVC in the BDW field. Uses the ES field on the ASR; QoS/CoS is ordered on the EVC as shown below.
- Ingress to EVC/OVC with QOS -- This type of specification is also handled using the BDW fields on the LOS portion of the EVC form. When QOS is being ordered, specify P1 or Priority 1 in the LOS field, and indicate the amount of Priority 1 bandwidth being ordered for the EVC/OVC in the BDW field. Then make another entry on the second line of the LOS field, specifying which template should be applied for the remainder of the EVC/OVC bandwidth, and indicate the quantity of remainder EVC bandwidth in the BDW field. The total of the QOS P1 bandwidth plus the Templated remainder bandwidth equals the total bandwidth assigned to this EVC/OVC.
EXAMPLE of QoS:
LINE 1: LOS field = P1 and BDW field = 10M
LINE 2: LOS field = Template 3 and BDW field = 90M
The above example is for rate limit on the EVC/OVC (Ingress to the EVC/OVC) at this UNI location where the EVC total bandwidth is 100 Mbps.
EXAMPLE of CoS:
LINE 1: LOS field = Real Time and BDW field = 20M
LINE 2: LOS field = Guaranteed Data and BDW field = 20M
LINE 3: LOS field = Business Class and BDW field = 10M
The above example is for rate limit on the EVC/OVC (Ingress to the EVC/OVC) at this UNI location where the EVC total bandwidth is 50 Mbps.
A Design Layout Record (DLR) can be requested via the order form. When calling CenturyLink Test and Turn Up, provide the order number returned on the DLR. If a DLR was not requested, provide the circuit number.
Expedited service may be requested for User Network Interfaces (UNIs), Ethernet Virtual Connections (EVCs), Operator Virtual Connections (OVCs), or both. Expedite should be requested separately for the UNI and EVC/OVC request, if both are to be expedited. Appropriate charges will apply to each request for expedited service.
Proactive Notification of Scheduled Network Maintenance
CenturyLink has a proactive e-mail notification system to let you know whenever scheduled network maintenance might impact your Metro Ethernet service.
In order to receive these e-mail alerts, an e-mail address must be included on your service request, to which the alert can be sent for each Metro Ethernet circuit. A separate e-mail address may be used for each individual circuit if desired.
To provide or update this information for existing circuits, please send the contact information via e-mail to QMetro Ethernet.ProactiveNotification@centurylink.com.
Metro Ethernet services which do not have an e-mail address on file will no longer receive proactive maintenance notifications for maintenance which occurs during the standard maintenance window – Monday through Friday, 4 a.m. to 7 a.m. local time. If maintenance that may affect Metro Ethernet service is scheduled to occur outside the standard maintenance window, CenturyLink will make every attempt to inform you.
