TESTING
After the RFL VF-15C module has been configured and installed, it should be tested for proper
operation before it is put into service. If a module is set up for two-channel operation, test each channel
separately.
EQUIPMENT REQUIRED
1. Telephone Set, Type 2500 or equivalent (for RFL VF-16 module).
2. PBX Station Line (RFL VF-15C only).
3. Ring Generator.
4. 48-Volt Battery.
FXO/FXS TEST PROCEDURE
1. Verify that a ring generator and -48-volt talk current battery are connected to the multiplexer
containing the RFL VF-16 module, as described in the Installation section of the multiplexer
manual.
2. Connect the PBX line to the channel under test on the RFL VF-15C module.
3. Connect the telephone to the channel under test on the RFL VF-16 module.
4. Check the setting of DIP switches SW6-1 through SW6-5 on the VF-16 module. Check the
setting of DIP switches SW10-1 through SW10-5 on the VF-15C module. Make sure that both
modules are set to the same time slot.
5. Set both channels on both modules to Loop Start by setting DIP switches SW5-1 and SW6-6 in
the DOWN position for the VF-16 module, and DIP switches SW1-1 and SW3-1 in the DOWN
position for the VF-15C module.
6. Set both modules to local control by setting DIP switch SW6-9 in the UP position for the VF-
16 module, and DIP switch SW10-7 in the UP position for the VF-15C module.
7. Set service on for both modules by setting DIP switch SW6-10 in the UP position for the VF-
16 module, and DIP switch SW10-8 in the UP position for the VF-15C module.
The Service LED should be ON, on both modules. All other LEDs should be OFF.
8. Take the phone connected to the RFL VF-16 module off-hook and observe the presence of a
dial tone from the PBX.
The green LEDs at the VF-16 (DS5 for channel 1, or DS6 for channel 2) and
VF-15C (DS2 for channel 1 or DS4 for channel 2) should both be ON, indicating
an Off-Hook condition.
