Setting The Clock Source; Accessing The G.703 Interface; Configuring Line Coding - HP ProCurve 7000dl Series Basic Management And Configuration Manual

Setting the Clock Source

The other setting that directly affects the G.703 interface is the clock source.
Each narrow ProCurve Secure Router module can have only one clock source.
For E1 + G.703 modules, you set the clock source on the E1 interface that is
used for data. By default, the clock source for this E1 interface is line. With
this setting, the E1 interface takes its timing from the public carrier's equip-
ment. The G.703 interface, in turn, takes its clock from the E1 interface.
You may want the E1 + G.703 module to take timing from the PBX rather than
from the public carrier's equipment. To change the clock source setting for
the E1 interface to through, enter:
ProCurve(config-e1 1/1)# clock source through
For detailed information about configuring other settings for the E1 interface,
see Chapter 4: Configuring E1 and T1 Interfaces.

Accessing the G.703 Interface

The ProCurve Secure Router treats the G.703 port as an E1 interface. Because
it is the second port of the E1 + G.703 module, you access the G.703 interface
by entering the following command from the global configuration mode
context:
Syntax: interface e1 <slot>/2
For example, if the E1 + G.703 module is installed in slot 1, enter:
ProCurve(config)# interface e1 1/2
From this configuration mode context, you can begin to configure the G.703
interface.

Configuring Line Coding

You configure the line coding for the G.703 interface just as you would for an
E1 interface. The settings you select must match those used by the PBX.
