SL2100 GETTING STARTED GUIDE

7.4 Test the Outside CO Lines

Test each line in turn and only test the lines you have connected.
1) To test CO1.
1) Lift the handset on the multiline telephone and dial #9 (Trunk Access Code) + 001 (Trunk
Number).
If you hear an exchange dial tone, the line is working correctly. If you do not hear an exchange
dial tone, check the connections from the outside CO line to the SL2100 and ensure both wires
are connected to CO1 as shown in
2) To test CO2.
1) Lift handset of a multiline telephone and dial #9 (Trunk Access Code) + 002 (Trunk
Number).
If you hear an exchange dial tone, the line is working correctly. If you do not hear an exchange
dial tone, check the connections from the outside CO line to the SL2100 and ensure both
wires are connected to CO2 as shown in
3) To test CO3.
1) Lift handset of a multiline telephone and dial #9 (Trunk Access Code) + 003 (Trunk
Number).
If you hear an exchange dial tone, the line is working correctly. If you do not hear an exchange
dial tone, check the connections from the outside CO line to the SL2100 and ensure both
wires are connected to CO3 as shown in
The RJ61 socket (CO1-3) has for three CO ports, therefore if you connect one CO port directly
to an R61 socket, you can get the first CO port instead of the three port. However if you need
more than four ports, you need to consider other CO Interface and wiring.

Section 8 Power Failure

When an AC power failure occurs, all the phones stop working even though the line or
telephone are in use.

8.1 Use the External Backup Battery Box (option) to connect each chassis

The external backup battery box (Option: IP4WW-Battery Box) with batteries provides
power to the system when AC power fails.
The backup time is about one hour depends on the traffic.
For more details refer to the Hardware Manual.

Section 9 Install Optional board and equipment

Refer to the Hardware Manual for details on optional units and equipment.
