The PA-MC-8TE1+ is a Cisco 8-port multichannel T1/E1 PRI port adapter whose interfaces are set as either T1 or E1. The card type command makes that choice for the whole card, there is no default, and the adapter does not function until the type is set. Changing it later means removing the card, saving the running configuration to NVRAM and rebooting the router before reinserting the card.
T1 controllers use SF or ESF framing with B8ZS line code, and E1 controllers use CRC4 framing with HDB3. T1 channel groups are numbered 0 to 23 with time slots 1 to 24, while E1 groups are numbered 0 to 30 with time slots 1 to 31. An adapter holds up to 256 channel groups, each at 56 or 64 kbps, and each controller takes one PRI group. Interfaces use a 16-bit CRC by default, with 32-bit CRC available.
It is supported in Catalyst 6000 family switches and Cisco 7600 Series routers with the FlexWAN module, Cisco 7200 Series and 7200 VXR routers, the 7201, 7301 and 7401ASR routers, the 7304 PCI Port Adapter Carrier Card, and Cisco 7500 Series routers. The two- and four-port PA-MC-2T1 and PA-MC-4T1 adapters point to this 8-port model as their upgrade path. The remaining router port adapters are collected in Cisco interface cards.
