Installation
Setting the Address on the OCC-1
Before installing the OCC-1 in the
OMM, set the address on S1. Use S1,
DIP switches SW1-SW8 to set the
network address. Refer to the CSG-M
configuration printout for the address
of the module. Use the Network
Address Programming Table at the end
of this chapter to set the address for
this switch.
Switch S2 is not presently used, but it
must be left in place.
Location of the User Key for the ASC-2
If the system has NO backup ampli-
fier, place a jumper across terminals 3
and 4.
After the addresses and jumpers are
set, install the ASC-2 in the OMM,
being sure that the module is riding in
the card guides and is firmly seated in
the card edge connector.
Installing the OCC-1
The OCC-1 plugs into a half-width slot
on the OMM and comes with an
installation kit that consists of the
following:
Four end of line resistors: Three -
P/N 140-820396 (Audio Risers) and
One -P/N 140-820390 (Telephone
Riser)
One user key
Switch S1 and Jumper E1 on the OCC-1
Setting Jumper E1
If the EL-410C/D amplifier is used,
place jumper E1 in the right-hand
position. This connects the backup
amplifier input negative side to the
MXLV power supply.
Place the user key from the installation
kit in the OMM-1 card edge connector
for the OCC-1 (between positions 21-
22 and 23-24).
