The PA-MC-2T1 is a Cisco 2-port multichannel T1 port adapter with integrated CSU/DSU functionality. It is a single-width adapter that adds CSU, DSU and DS0 channel support to the router, and its two independent 100-ohm T1 connections use RJ-48C receptacles that can all be used at once.
Each T1 port moves data both ways at 1.536 Mbps within a 1.544 Mbps line (+/- 32 ppm), using AMI or B8ZS line code. A port can be split into up to 24 serial interfaces numbered 0 to 23, each using up to twenty-four 64-kbps time slots at n x 56 kbps or n x 64 kbps. Up to 128 interfaces can be set up per adapter. In ISDN PRI mode each T1 has 23 B channels and one 16 kbps D channel, with dial-on-demand routing.
T1 features include selectable line build out of 0 dB, -7.5 dB or -22.5 dB and receiver gain between 26 dB and 36 dB. The adapter fits Cisco 7120, 7140, 7200 Series, 7201, uBR7223 and uBR7246 routers, the 7304 PCI port adapter carrier card, and a VIP in 7000 or 7500 Series routers. The Catalyst RSM/VIP2 does not support it. The spare ordering number is PA-MC-2T1=. Port adapters for other WAN links continue in Cisco interface cards.
