Configuring the E1 + G.703 and T1 + DSX-1 Modules
Quick Start
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
This chapter includes only the T1 configuration steps that directly affect the
DSX-1 interface. You must configure the other settings for the T1-carrier line,
configure the Data Link Layer protocol, and bind the physical interface to the
logical interface. For detailed information about configuring the T1 interface
for data communications, see Chapter 4: Configuring E1 and T1 Interfaces.
Configuring the DSX-1 Interface
1. Access the T1 interface for the DSX-1 module:
Syntax: interface t1 <slot>/2
For example, if the T1 + DSX-1 module is in slot 1, enter
ProCurve(config)# interface t1 1/2
2. Configure the line coding to match the coding used by the PBX. The
default setting is B8ZS.
Syntax: coding [ami | b8zs]
For example, to configure the T1 interface to use the coding ami option,
enter:
ProCurve(config-t1 1/2)# coding ami
3. Configure the frame format. The default setting is ESF.
Syntax: framing [d4 | esf]
For example, to configure the T1 interface to use D4, enter:
ProCurve(config-t1 1/2)# framing d4
