Configuring the E1 + G.703 Module
The E1 + G.703 module has:
■ an E1 port
■ a G.703 port
The E1 port handles the data communications. The G.703 port receives all
the channels from the E1-carrier line that are not mapped for data and drops
these channels into a PBX. When you configure an E1 + G.703 module, you
must configure it to synchronize the data transfer between the public carrier,
the two ports (or interfaces), and the PBX. You must also configure which
channels are dropped into the PBX.
Making the Physical Connection
Like other ProCurve Networking E1 modules, the E1 port on E1 + G.703
modules include a built-in Digital Service Unit (DSU). You use unshielded
twisted pair (UTP) cabling with RJ-48C connectors to connect the E1 interface
to the Channel Service Unit (CSU) provided by your public carrier. (For more
information about the DSU or CSU and other public carrier equipment used
in an E1 connection, see Chapter 4: Configuring E1 and T1 Interfaces.)
