The optional Voice Compression module (VCM) consists of one T1/E1 interface 
which you connect to a PBX trunk. The T1/E1 interface’s 24/31 DS0 channels can 
carry individual voice, fax, modem, or data connections—or you can bundle 
multiple DS0s to provide connections for high-rate applications such as video 
conference or multiple-link PPP. For CCS, a DS0 is used as an ISDN D-channel for 
carrying signal messages.

Configuring the VCM involves the following tasks:

Configuring the channels
