DS0 Groups
For digital voice ports, a single command, ds0-group, performs the following functions:
■ Defines the T1/E1 channels for compressed voice calls
■ Automatically creates a logical voice port
■ Defines the emulated analog signaling method the router uses to connect to the PBX
or PSTN
When you purchase a T1 or E1 connection, make sure your service provider gives you
the appropriate settings.
