The CMM is a Cisco Catalyst 6500 Series line card that provides flexible and highdensity
VoIP gateway and media services. A Catalyst 6500 Series Switch can handle multiple
digital trunk interfaces. For example, the Cisco Catalyst 6509 Switch supports up to
144 T1/E1 connections by using eight communications media modules with 18 ports
each. These gateway and media services allow organizations to connect their existing
TDM network to their IP communications network, provide connectivity to the PSTN,
and enable conferencing and transcoding services. Go to http://www.cisco.com/go/
