Interfaces Overview" on page 577.
Each T1 interface has 24 time slots (DS0s). 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 T1 interface.
Example: Configuring Channelized T1 IQ and IQE Interfaces
Configure a channelized T1 interface as an unpartitioned, clear channel.
