E1 + G.703 And T1 + Dsx-1 Modules - HP ProCurve 7000dl Series Basic Management And Configuration Manual

E1 + G.703 and T1 + DSX-1 Modules

The E1 + G.703 and the T1 + DSX-1 modules allow you to use some channels
of a carrier line for data and some channels for analog voice. When you
configure one of these modules, you should first configure the E1 or T1
interface that will be used for data. As part of this configuration, you must
assign the channels that will be used for data to the E1 or T1 interface. The
remaining channels are then automatically assigned to the G.703 or DSX-1
interface.
When you configure the E1 or T1 interface, you set the clock source for the
entire module. If you set the clock source to line, the module will take its
timing from the public carrier's equipment that is attached to the E1 or T1
interface. If you set the clock source to through, the module will take its timing
from the PBX that is attached to the G.703 or DSX-1 interface.
For more information about E1 or T1 settings, see "Configuring E1 and T1
Interfaces" on page 14-54.
In the Secure Router OS, the G.703 interface is referred to as an E1 interface.
Specifically, it is the interface for port 2 in the slot where the E1 + G.703 module
is installed. For example, if the E1 + G.703 module is installed in slot 2, the
G.703 interface is E1 2/2.
The DSX-1 interface is referred to as a T1 interface. It is the interface for port 2
in the slot where the T1 + DSX-1 module is installed. For example, if the T1 +
DSX-1 module is installed in port 1, the DSX-1 interface is T1 1/2.
However, to avoid confusion between the interfaces used for data and the
interfaces used for analog voice, these instructions will use the terms G.703
interface and DSX-1 interface.
When you configure the G.703 or DSX-1 interface, the settings that you enter
should match those used by your private branch exchange (PBX). To configure
the G.703 or DSX-1 interface from the Web browser interface, complete the
following steps:
1. From the navigation bar, click Physical Interfaces. The Physical Inter-
faces window is displayed.
2. Select the G.703 or DSX-1 interface. The configuration window for that
interface is displayed.
