Basic Installation
ONS/CLASS and LS/CLASS ports
Connect the LS CLASS trunks and any ONS phones to the line ports on
the back of the controller using standard 4-conductor cables with RJ-11
connectors.
After connecting the LS trunks, use the Line Quality Test to program the
audio configuration settings. For more information, see “Running the Line
Quality Test for LS Trunks” on page 114.
Refer to the following table for circuit assignments and default numbering
for ONS phones.

Notes:
1.
Tip and Ring correspond to pins 3 and 4 of the RJ11 connector
respectively.
2. ONS/CLASS ports do not support high-voltage message-
waiting lamps.
3. Trunks circuits located at 1/13/7 and 1/13/8 on the AMB and
1/13/13 and 1/13/14 on the AOB are System Fail Transfer (SFT)
trunks. In the event of a system or power failure, the trunks
connect to ONS circuits 1/13/3 and 1/13/4 on the AMB and
circuits 1/13/19 and 1/13/20 on the AOB respectively.
4. ONS ports are not designed with the necessary safety protection
for off premise connections. ONS ports must not be used to
connect to off premise phones.
