FXO+ Dual Voice Option Module
The FXO+ rear panel includes a plastic plug over a
cutout for additional connectors. This allows a plug-
on board to be added to the FXO+ module. The PORT
X.Y indication is linked to the port numbering philoso-
phy of the TSU 100 product family. The
X
represents
the slot number, and the
.Y
indicates the port
number. For the TSU 100 application, there is only
one option slot. Therefore the port designations for
the two FXO voice ports will be 1.1 and 1.2. If added,
the plug-on board port designation would be 1.3 and
1.4. These port numbers appear in the front panel
liquid crystal display (LCD) menu displays.
