Cisco PA-MC-2T3+
2 port multichannel T3 port adapter
Product Highlights
The two-port enhanced multichannel T3 port adapter for the Cisco 7500 and 7200 series platforms is the next step in port density and flexibility for enterprise and Internet service provider WAN link aggregation. Each adapter has two T3 ports that can be independently configured for either multichannel T3 or packet-over-T3 operation. When configured as T3 ports, connections to DS3 and subrate DS3 services can be provisioned. When configured as multichannel T3 ports, up to 56 T1 links can be brought in on this single-wide port adapter. Each T1 can be further channelized to DS0 making the two-port enhanced multichannel T3 port adapter the most flexible interface for WAN provisioning.
