Cisco PA-MC-2E1/120 is a 2-port multichannel E1/PRI port adapter. It brings two independent 120-ohm E1 connections through RJ-48C connectors and can run up to 62 separate full-duplex HDLC interfaces, as channelized E1, fractional E1, full E1 or unframed E1. Each port moves data both ways at 2.048 Mbps and conforms to ITU G.703 and G.704.
In channelized E1, each port can be split into up to 31 serial interfaces numbered 0 to 30, using timeslots numbered 1 to 31 at 64 kbps each. For ISDN PRI, each E1 interface has 30 B channels and one D channel of 64 kbps. Line code is AMI or HDB3 on a 120-ohm unshielded twisted-pair cable. Encapsulations are Cisco HDLC, Frame Relay, PPP and SMDS DXI, with network and payload loopbacks and bonding of several E1s.
It is a single-width adapter for Cisco 7100 Series, 7200 Series, 7200 VXR, uBR7200 Series, 7201, 7301 and 7304 routers, and for a VIP in 7000 and 7500 Series routers. The PA-MC-8E1/120 is the 8-port model, and only that model fits the Catalyst RSM/VIP2 and the Catalyst 6000 FlexWAN module. Browse router hardware in Cisco routers.
