Install a terminated 600-ohm dB meter into the DROP RCV jacks for
channel 2. (It can be the same meter as used in step 3 above.) Verify a
level of +7 dBm. If the level is not correct, adjust the front panel re-
ceive potentiometer for RCV 2.
8.
Remove the power
9.
Reset the bridge switch to RPTR, and reset loopback switches S2 and
S101 to OFF.
10.
Reinstall the power
11.
To verify the levels of the bridge, insert a -16 dBm, 600 ohm termi-
nated 1 kHz signal into the DROP XMT jack for channel 1 on the
front panel of the 46105 module.
12.
Verify with the dB meter (not terminated) a level of 0 dB at both XMT
LVL test point jacks for channel 1 and 2.
13.
Install a terminated 600-ohm dB meter into the DROP RCV jacks for
channel 2. Verify a level of +7 dBm.
14.
With the meter still terminated, move the meter to the DROP RCV
jack for channel 1 and verify a reading of -40dB or more negative.
15.
Insert a -16 dBm, 600 ohm terminated 1 kHz signal into the DROP
XMT jack for channel 2 on the front panel of the 46105 module.
16.
Verify with the dB meter (not terminated) a level of 0 dB at both XMT
LVL test point jacks for channel 1 and 2.
17.
Install a terminated 600-ohm dB meter into the DROP RCV jacks for
channel 1. Verify a level of +7 dBm.
18.
With the meter still terminated, move the meter to the DROP RCV
jack for channel 2 and verify a reading of -40dB or more negative.
19.
This completes the testing and alignment for the 46105.

(SAM)
The SAM allows for annunciation of four levels of alarms: A, B, C,
and D. Each of these sections contain three LEDS:
♦
C/O - lights when the Alarm Cut-Off (ACO) switch for that
section is on.
♦
EXIST - indicates an existing alarm
♦
NEW - indicates an unacknowledged alarm. Pressing the ACK
button clears this LED
The default setting for all alarms is the D level alarm. Any level
can be assigned to any point by using the craft port of the MAP
and configuring the level of alarm per each point. If a level is not
defined, it is defaulted to a D level. See the MAP section above to
set the levels of alarms.
