Configuring the T1 + DSX-1 Module

Making the Physical Connection
1. Use UTP cabling with RJ-48C connectors to connect the T1 interface to
the wall jack provided by your public carrier.
2. Use crossover UTP cabling with RJ-48C connectors to connect the DSX-
1 interface to the PBX.

Assigning the Channels to the T1 Interface

When you configure a DSX-1 interface, you first configure the T1 interface to
handle the data communications. As part of this configuration, you assign the
number of channels that you will use for data to the T1 interface, and the
remainder of the channels are automatically passed to the DSX-1 module.
In addition, you can configure the clock source (rather than simply accepting
the default setting of line). For a T1 + DSX-1 module, the clock source is set
only on the T1 interface.
To assign the channels to the T1 interface, complete these steps:
1. From T1 interface configuration mode context, enter the following
command:
Syntax: interface t1 <slot>/1
Replace <slot> with the slot number where the T1 module is housed. For
example, if the T1 module is in slot 1, enter:
ProCurve(config)# interface t1 1/1
2. When you divide channels between the T1 interface and the DSX-1 inter-
face, you must create two groups of contiguous channels. Use the follow-
ing command to create a TDM group and assign it the number of channels
used for data.
Syntax: tdm-group <number> timeslots <range of numbers>
For example, if you want to use channels 1-12 for data, enter:
ProCurve(config-t1 1/1)# tdm-group 1 timeslots 1-12
3. Configure the clock source for the interface. By default the clock source
for the interface is through. To configure the T1 + DSX-1 interface to take
the timing from the PBX, enter:
ProCurve(config-t1 1/2)# clock source line
