1. For US based ISPs coast-to-coast nationwide OC-48/STM16 (2.4 Gbps) or larger public IP backbone network. 2. Presence at three or more geographically dispersed public peering points listed above for domestic ISPs. 3. Presence at two or more public peering points listed above for International ISPs. 4. A total minimum busy hour traffic exchange of 50 Mbps with SBC Internet’s Autonomous System Number will be required. 5. Must not have been an IP transit customer of SBC Internet in the past six (6) months. 6. Willingness to enter into a Bilateral Interconnection Agreement and Non-Disclosure Agreement with SBC Internet. 7. Operation of a 24x7x365 Network Operations Center (NOC) that proactively monitors all peering connections and provides

an escalation path to quickly identify and resolve network problems. 8. No requirement for a balanced traffic exchange ratio due primarily to the asymmetric nature of current broadband metallic

transmission systems such as ADSL and cable modems. 9. Joint quarterly capacity planning reviews for interconnection augmentation to accommodate traffic growth and minimize the

SBC Backbone :: Peering : Index Verizon Response - Exhibit 15.D


possibility of latency or packet loss between both networks. 10. Hot-potato routing is implied (i.e. we will not send or honor MEDs) 11. Consistent routes announcements at all public peering points. 12. MD5 passwords are required for all sessions. 13. Meeting the guidelines above for public peering with SBC Internet is not a guarantee that peering will be established. SBC

Internet reserves the right to not grant peering to an applicant based on business reasons. 14. Peers who are unable to maintain the minimums listed above will be given 30 days written notice to remedy the situation. 15. Periodic review of the policies above to ensure that the criteria and eligibility requirements are consistent with SBC Internet

growth and expansion is acknowledged.

The guidelines for establishing private peering with SBC Internet Services are as follows:

1. For US based ISPs coast-to-coast nationwide OC-48/STM16 (2.4 Gbps) or larger public IP backbone network. 2. Presence at three or more geographically dispersed private peering cities listed above for US based ISPs. 3. Presence at two or more geographically dispersed private peering cities listed above for International ISPs. 4. A total minimum busy hour traffic exchange of 250 Mbps with SBC Internet’s Autonomous System Number will be required. 5. Must not have been an IP transit customer of SBC Internet in the past six (6) months. 6. Willingness to enter into a Bilateral Interconnection Agreement and Non-Disclosure Agreement with SBC Internet. 7. Operation of a 24x7x365 Network Operations Center (NOC) that proactively monitors all peering connections and provides

an escalation path to quickly identify and resolve network problems. 8. No requirement for a balanced traffic exchange ratio due primarily to the asymmetric nature of current broadband metallic

possibility of latency or packet loss between both networks. 10. Consistent routes announcements at all private peering points. 11. Hot-potato routing is implied (i.e. we will not send or honor MEDs) 12. MD5 passwords are required for all sessions. 13. Meeting the guidelines above for private peering with SBC Internet is not a guarantee that private peering will be

established. We prefer to trial peering at several locations to best establish circuit sizing for privates prior to committing dedicated resources. SBC Internet reserves the right to not grant peering to an applicant based on business reasons.

14. Both companies shall agree to sustain an equal financial burden for the costs of private interconnection via local facilities. 15. Peers who are unable to maintain the minimums listed above will be given 30 days written notice to remedy the situation. 16. Periodic review of the policies above to ensure that the criteria and eligibility requirements are consistent with SBC Internet

growth and expansion is acknowledged.

TelCove's ATM/Frame Relay networkcurrently consists of nine Core Switchlocations interconnected with diversely

routed OC-12c or OC-48c links.

Each TelCove served market which areequipped with an Edge Switch,

is connected to a Core POP locationwith at least a 45 Mb/s (DS-3) link.All other markets are backhauled

to the nearest Edge Switch.

Although this diagram illustrates logical connectivity, each of the links shown

are typically delivered over either a diverse DWDM or SONET protected

network.

TelCove's IP network currently consists of two Core POP locations, Pittsburgh and Atlanta,

which are interconnected with Gig-E diverse links.Each POP is also connected with at least 622Mb/slinks to a minimum of three separate Internet transit

providers, enabling, survivable connectivity to the rest of the Internet community.

Each TelCove served market which is equipped with an access router is connected to a Core POP

location with at least a 150 Mb/s protected link.All other markets are backhauled to the nearest

access router for network connectivity.

Although this diagram illustrates logical connectivity,each of the links shown are typically delivered overa diverse DWDM network with SONET protection

enabled, which provides optimum resiliency.
