1- and 2-Port Multichannel Enhanced Capability Port Adapters provide hardware
offload support of Multilink Point-to-Point Protocol (MLPPP), Multilink Frame Relay
(MLFR), link fragmentation and interleaving (LFI), and FRF.12 at T3 line rate.
Product Overview
The 1- and 2-port multichannel T3 port adapters for the Cisco 7200 Series Routers and Cisco
7301 Router (Figure 1) are enhanced versions of the previous multichannel T3 port adapters (part
numbers PA-MC-T3 and PA-MC-2T3+). The new port adapters address specific scalability
challenges by increasing performance and lowering CPU usage. They offload advanced
capabilities and features from the CPU, delivering them directly to meet enterprise and service
provider WAN link-aggregation service requirements. Each port adapter T3 interface can be
independently configured for either multichannel T3 or clear-channel packet-over-T3 operation.
With T3 port configurations, connections to DS-3 and subrate DS-3 services can be provisioned.
With multichannel T3 port configurations, up to 28 T1 links per T3 interface can be brought in on a
singlewide port adapter. Each T1 can be further channelized to DS-0, making the port adapters
highly flexible interfaces for WAN provisioning. The combination of multichannel T3 and clear-
channel functions makes the Cisco 1- and 2-Port Multichannel Enhanced Capability Port Adapters
ideal for today's rapidly changing WAN environment. Specific features such as MLPPP, MLFR,
LFI, and FRF.12 have been offloaded from the CPU to further enable agile response to new
services while using existing infrastructure connections to better advantage.
As an integral part of a service node where customer bandwidth needs are uncertain, the port
adapters allow service providers to avoid determining beforehand how ports will be allocated
between DS-0, DS-1, and DS-3 connections. For enterprise remote-site connection, the flexibility
to support DS-0, DS-1, and DS-3 connections means the port adapters reduce equipment
expenditures by integrating the capabilities and services of numerous port adapters onto a single
adapter. They also provide investment protection by growing with the enterprise to meet the needs
of both today's DS-0 and DS-1 aggregation networks and tomorrow's T3 aggregation networks.
