TESTING
After the RFL VF-8A 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. Minimum of two (2) Telephone Sets, Type 2500 or equivalent; one for each VF-8A module.
2. External Ring Generator at each location. (optional)
3. External –48 Volt Battery at each location. (optional)
TEST PROCEDURE
1. Determine whether the –48V talk current battery is to be provided by the IMUX 2000 Power
Supply or an external source for each location. Verify that the power supply is strapped
accordingly at each location. If an external source is to be used, make the required connections
to the IMUX Power Supply I/O at that location, as described in the Installation section of the
multiplexer manual.
2. Determine whether the local ring generator (on the MA-306 I/O) or an external ring generator
is to be used at each location. Verify that the MA-306 I/O is strapped accordingly at each
location. If an external ring generator source is to be used, make the required connections to
the IMUX Power Supply I/O at that location, as described in the Installation section of the
multiplexer manual.
3. Connect the telephone to each MA-306 I/O of corresponding VF-8A module under test.
4. Check the setting of DIP switches SW2-1 through SW2-5 for each VF-8A module. Make sure
that each VF-8A intended to be part of the same voice network are strapped for the same time
slot.
5. Verify each VF-8A has a unique “Unique” 3-digit station ID. Visually inspect rotary switches
SW4 through SW6.
6. Set each VF-8A module to local control by setting DIP switch SW1-7 in the UP position.
7. Set service ON for each VF-8A module by setting DIP switch SW1-8 in the UP position.
The SRVC LED (DS3) should be ON, on each module. All other LEDs should be
OFF for each module, indicating all phones are on-hook and voice circuit is in the
idle condition.
