7. The following items are required for 9300 relays equipped with fiber optic modules:
a. Two fiber optic patchcords.
8. The following items are required for 9300 relays equipped with short haul fiber interface modules:
(See Figure 7-1)
a. Two Fiber Service Units. (RFL part No. 105075-X)
b. Four fiber optic patchcords.
c. An RFL DCE emulator (RFL part No. 105880).
d. A +5Vdc power supply for the RFL DCE emulator.
e. Two RS-449 cable assemblies used to connect the fiber service units to RFL DCE
emulator (RFL part No. 302196-X or equivalent).
9. The following items are required for 9300 relays equipped with G.703 modules:
a. Two twisted pairs of wire several feet long.
7.3 SYSTEM SETUP
Use the following procedure to prepare for the laboratory acceptance tests:
1. Verify that the Alarm I/O module is configured for your station battery voltage, or system damage may
result. Refer to paragraph 21.2 for Alarm I/O module strapping instructions.
2. Connect the communications transmitters and receivers of the two RFL 9300s, in accordance with Fig-
ure 7-1.
RFL 9300s with modems will require two twisted pairs.
RFL 9300s with direct digital modules will require two RS-449 cables and a DCE emulator.
RFL 9300s with fiber optic modules will require two fiber patchcords.
RFL 9300s with short haul fiber interfaces will require a DCE emulator, two fiber service
units, two RS-449 cables and four fiber optic patchcords.
RFL 9300s with G.703 modules will require two twisted pairs.
3. Start up the two RFL 9300s, using the procedures given in Section 6 of this manual.
Both RFL 9300s should be in the STANDBY mode, with two moving dots on the display
and no alarm indications.
4. Using the READ display mode, verify that the delay in the communications link is normal.
The PINGPONG value should read about 18 ms for modem versions, or 4 ms
for direct digital or fiber versions.
