Configuring a digital voice interface

The description, shutdown, receive gain, transmit gain, and cng-on commands have the same functions
as those for analog voice interfaces. For more information about those commands, see related sections

in "Configuring analog voice interfaces."

Configuring a timeslot set

Creating a timeslot set

To use an E1 interface, you need to create a timeslot set and configure the signaling type, Then, the

system automatically creates a logical digital voice interface. Timeslot 0 is used for frame synchronization,
timeslot 16 is used to transmit signaling, and the other 30 timeslots are used to transmit voice packets.
A T1 interface is used in a similar way to an E1 interface, except that it has 24 timeslots and timeslot 24

is used to transmit signaling.
Only RS signaling can be configured for a timeslot set.
To create a timeslot set:
