The WS-SVC-CMM-6T1 has six channelized T1 ports on RJ-48 connectors and 144 voice channels of G.711 and G.729. It is the 6-port T1 voice port adapter for the Cisco Communication Media Module, and the spare number is WS-SVC-CMM-6T1=.
The T1 line speed is 1.544 Mbps with AMI and B8ZS line codes, D4 (Super Frame) and Extended Superframe framing, and the ATT T1.1 and ANSI T1.403 physical interface standards. A link status LED is fitted. Regulatory entries are TIA/EIA-IS-968, CS-03, IEC 60950, UL 60950, FCC (CFR 47) Part 15 and CISPR-22.
A WS-SVC-CMM module accepts up to three of these adapters, with no E1 adapters mixed in. Ten T1s is the recommended maximum per module. The module needs Cisco IOS 12.4(8a) or later, and the chassis needs Catalyst OS 8.4(1) or native IOS 12.2(18)SXF3 or later.
The E1 counterpart is the WS-SVC-CMM-6E1. The host module goes in a chassis such as the WS-C6509-E 9-slot chassis, and more gateway and voice parts are in Cisco Catalyst 6500 miscellaneous cards.
