can be used in conjunction with the TA 750/850 FXO
(Foreign Exchange Office) access module, ADTRAN
part number 1175407L1, which resides in the
TA 750/850 that is located next to the Central Office
Switch.
Figure 2 provides an illustration of a typical
deployment using a TA 750 chassis with both FXO
and FXS access modules. This arrangement is used
where the TR-08 signaling format is not conveniently
available at the CO switch. The TA 750 at the CO will
combine a number of analog lines then multiplex them
for T1 transmission to the TA 750 at the customer
premises.
When using the TR-08 signaling option, the Quad
FXS can communicate directly with the Central Office
Switch without needing a Quad FXO. Figure 3
provides an illustration of a typical TR-08
deployment.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by
