Configuring NxDS0 IQ and IQE Interfaces

By default, all the time slots on a channelized T1 interface are used. To configure an
NxDS0 IQ or IQE interface on a Channelized T1 IQ or IQE PIC, you must configure
the number of time slots allocated to the NxDS0 IQ or IQE interface by including the
partition
hierarchy level, specifying the
For channelized T1 IQ or IQE interfaces, the partition number range is from 1 through
24.
For channelized T1 IQ or IQE interfaces (
1 through 24. You can designate any combination of time slots. To configure ranges,
use hyphens. To configure discontinuous time slots, use commas. Do not include
spaces. For more information about T1 time slots, see "Configuring Fractional T1
Time Slots" on page 585.

Example: Configuring an NxDS0 IQ or IQE Interface

Configure an NxDS0 interface that uses time slots 2 through 10. This configuration
creates the

Configuring Payload Loopback

Clocking and loopback options are configured at the controller level for all IQ-based
and IQE-based interfaces. However, for the channelized T1 IQ or IQE interfaces,
configure the payload loopback on the T1 interfaces instead of the channelized T1
IQ or IQE interface. To configure the payload option, include the
at the
By default, all the time slots on a channelized T1 IQ or IQE interface are used. There
can be a maximum of 24 channel groups per channelized T1 IQ or IQE interface.
Thus, you can configure a maximum of 240 channel groups per PIC.
To specify the DS0 channel group number in the interface name, include a colon (
as a separator. For example, a Channelized T1 IQ or IQE PIC might have the following
physical and virtual interfaces:
