subinterfaces, but you can use the display voice subscriber-line line-number.subnumber command
to view the call state of a subinterface.

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:
