Configuring the E1 + G.703 and T1 + DSX-1 Modules
Configuring the T1 + DSX-1 Module
For example, you could assign channels 1-12 to the T1 interface. Channels
13-24 are then automatically assigned to the DSX-1 module. To assign channels
to the T1 interface, move to the T1 interface configuration mode context and
enter the tdm-group command:
Syntax: tdm-group <number> timeslots <range of numbers>
ProCurve(config-t1 1/1)# tdm-group 1 timeslots 1-12
If you view the status of the T1 interface (after you configure a logical interface
and bind it to the T1 interface), you will see that channels 1-12 are marked
with an N. This means that they are "nailed," or assigned, to the T1 interface.
The channels assigned to the DSX-1 interface are marked with a D. (See
Figure 9-4.)
N o t e
If you have not yet entered a bind command to bind the T1 interface to a logical
interface, the channel assignments will not be displayed correctly.
