ACTION
Refer to Fig. 1.
NOTE:
If using a PABX 4-wire
trunk, start at step 2d.
Calibrate the two-wire RCV level.
Set tone generator to 1kHz and connect a
600 ohm terminated meter across the generator
terminals.
Remove the meter. Using a bantam-sized phone
plug, connect the tone generator to the 2-WIRE
DROP front panel jack of the 44443 Term Set.
Plug 600 ohm terminated meter into the 4-WIRE
XMT front panel jack of the 44443 module.
NOTE:
If using a PABX 2-wire trunk, skip steps
2d and 2e.
Set the tone generator for 1kHz and connect a
600 ohm terminated meter across the generator
terminals.
Remove the meter. Connect the tone generator
to the TRANSMIT DROP jack of the 44023
module.
Press the TEST/RST switch on the 44023 front
panel.
Connect the meter to the TRANSMIT LINE test
points on the 44023 module front panel.
Disconnect transmit receive level.
Calibrate the transmit receive level.
The TEST/RST switch on the front panel of the
44023 should not be changed.
Set the tone generator output for existing system
level and 1kHz. Connect it to the RECEIVE
LINE test points on the 44023 front panel.
Move meter to the RECEIVE DROP front panel
jack on the 44023 and terminate in 600 ohms.
NOTE: If testing an A15-00331-01, go to step 4.
Move meter to the 2-WIRE DROP jack on the
front panel of the 44443 module.
Test complete. Remove all test equipment and
reconnect the external equipment. Press the
TEST/RST button on the 44023.
RESULT
The functional schematic shows the normal
systems levels used in the alignment.
Set the generator output level for -4dBm.
Meter shows XMT level. Set the level for
-16dBm by using the front panel XMT pad
switches on the 44443 module.
Set the generator output level for -16dBm.
Off-hook LED comes on.
Set the level for existing system
requirements.
Off-hook LED is on. press TEST/RST switch
on the 44023 if it is not.
Meter shows DROP RECEIVE level. Adjust
receive pot for +7dBm.
Meter shows transmit level to CO line. Set
level for -6dBm using the 4-wire RCV front
panel pads on the 44443 module.
All LEDs should go out.
