Only a subset of the E1 options is valid for the channelized configuration; you specify
the time slots using the
Naming" on page 63. For more information about the E1 and DS0 options, see "E1
Interfaces Overview" on page 561 and "T1 Interfaces Overview" on page 577.
Each E1 interface has 32 time slots (DS0s), in which time slot 0 is reserved. You can
combine one or more of these DS0 time slots (channels) to create a channel group
(NxDS0). There can be a maximum of 24 channel groups per E1 interface.

Configure a channelized E1 interface as an unpartitioned, clear channel:
