©1999 Exicom Technologies (1996) Ltd 2-9 Issue 2 - February 2001
Note: The EX7100 automatically detects the presence of an Exchange interface card.
The terminal is configured for 2-wire or 4-wire+E&M, in software via the front panel
keypad. Refer to Section 3.4.3 for configuration details.
The Exchange terminal may also be software configured, via the front panel keyboard, as
a point to point Data terminal. Refer to Section 3.4.3 for configuration details.
2.7.3 Subscriber Terminal Connections
The EX7100 Subscriber terminal provides six 2-wire telephone circuits for connection to
equipment such as telephones, payphones, EFT-POS terminals, etc.
These circuits are accessed from the terminal via the 50-way Champ connector, labelled
‘LINE INTERFACE’, on the terminal’s rear panel. (For detailed pin-out information refer to
Appendix A.6)
The Subscriber terminal may be supplied with a 3 or 10 metre cable that can be plugged
directly into this connector. The un-terminated end of the cable may be either wired
directly to the user equipment, to an existing MDF, or to Exicom’s optional Line
Terminating Frame (LTF). Contact your Exicom International Supplier for details
Note: The EX7100 automatically detects the presence of a Subscriber interface card.
The LTF is available with various connector options, as well as optional Primary Lightning
Protection circuitry. Contact your Exicom International Supplier for further details.
2.8 Earthing the Terminal
The provision of a suitable earth for the terminal is the responsibility of the installer. The
EX7100 has a screw terminal on the rear panel to connect the terminal to earth.
This will assist in preventing damage to the terminal from lightning strikes, particularly
strikes to the telephone cables. Protection from strikes to the antenna system may be
provided by fitting the recommended antenna lightning arrester.
For these protective measures to be effective, the system requires a good earth
connection. Mains earth is not
adequate, nor is a thin wire or any wire with bends or twists
in it.
The best earth connection is using a suitably heavy wire (e.g. >4 mm
2
copper cable)
connected straight to an earthing stake driven into the ground
If this is not possible, connect the earth cable to the equipment rack ground system.
2.9 Other Rear Panel Connections
The EX7100 is fitted with several other rear panel connectors as detailed below. Some of
these connectors will not be used for all applications, however descriptions of their
functions are detailed below.
Note: Detailed pin-out information can be found in Appendix A.
