XO Communications Deploys Cisco Ethernet over SONET/SDH (EoS)

XO Communications is deploying new Cisco Ethernet over SONET/SDH (EoS) technology on many of the more than 4,000 Cisco ONS 15454 Multi-service Provisioning Platforms (MSPPs) currently deployed in its network.

Cisco said that as part of this transition, XO Communications is evaluating two innovations to streamline its network transformation:

  • Cisco Multilayer, Multi-rate, 10-Port Line Card, with 10 Gbps Ethernet over SONET/SDH (EoS) capacity (ML-MR-10) enabling a wide range of Ethernet services with Layer 2 switching, RPR, and advanced QoS capabilities. Cisco ML-MR-10 cards can be used for any Ethernet service type by changing the SFP module plugged into the Ethernet port.

  • Cisco Carrier Ethernet, Multi-rate, 10-Port Line Card, with 10 Gbps Ethernet over SONET/SDH (EoS) capacity (CE-MR-10), a next-generation version of the Carrier Ethernet blade for the 15454, enabling private line Ethernet services.

Both of these platforms quadruple the capacity of previous cards in the same line from 2.5 Gpbs to 10 Gbps on a single blade, while still supporting a wide range of protocols. They also provide 10-client ports, each of which is soft form factor pluggable (SFP).

XO Communications offers a broad range of IP-based services, including Metro Ethernet for Dedicated Internet Access (DIA), private line (point-to-point) services, VoIP, IP Telephony and IP-VPN, which are available in 75 U.S. metropolitan markets. The XO network has a large SONET infrastructure and associated services, making Cisco Ethernet over SONET/SDH (EoS) technology well-suited to scaling the network.
