TURN UP STEPS
Insert card into slots 1-6 on the TA 750.The unit will automatically map
DS0s in the T1 as noted below.

Verify LED sequencing.LEDs will stop sequencing once unit is initialized.
Note: If the unit is inserted into a physical slot which has its timeslots allocated to the FT1
(DSX-1) or Nx56/64 port, the LEDs will sequence continually, indicating a problem.
The time slots must be freed up using the menu interface before the unit will become
operational.

If factory default settings to be used for the application, then installation
is complete. If further provisioning is desired proceed to step 4.
FACTORY DEFAULT SETTINGS
The FXS unit has factory default provisioning:FXS mode,loop start signaling and
automatic loop provisioning. The automatic loop provisioning function will
automatically set the line impedance and gain after the first off hook event.
The FXO factory default settings are FXO mode and loop start signaling.
If different settings are desired, the VT 100 terminal interface is used.

after 5c)
TESTING
Self Test
■
Performed when the Quad FXS or FX0 is inserted into an active chassis
to verify proper operation of critical circuits.
Initiated Tests
■
Digital Loopback Test – loops back DS0 data coming from the network
for each individual channel.
■
Network On-Hook / Off-Hook Test – tests signaling sent to the network
by the unit.
■
Customer Ring Test (FXS only) – activates the unit’s ring relay in a 2-on /
4-off ring cadence, providing ringing to the customer loop.
■
1000 Hz DRS Tone Generation Test – sends DRS signal on the receive
path to the loop and transmit path towards Carrier.
Note: All tests except self test are initiated through the TA 750 BCU Admin Port, TA 850
RCU,or TA 1500 SCU.
Note: The Quad FXS is for use in the TA 750 and the TA 850.
The Quad FX0 is for use in the TA 750,the TA 850,and the TA 1500.
Note: The 1175408L2 is completely interchangeable with the 1175408L1.
The 1175407L2 is completely interchangeable with the 1175407L1.
