1-4 FXS+ Quad Voice Option Module User Manual 61202300L1-1
PHYSICAL DESCRIPTION
The FXS+ is an option module which plugs into the op-
tion slot in the rear of the TSU 100. See Figure 1-1.
Figure 1-1. FXS+ Quad Option Modules
The PORT X.1 indication is linked to the port numbering
philosophy of the TSU 100 product family. The X repre-
sents the slot number, and the .1 indicates the port num-
ber. For the TSU 100 application, there is only one option
slot.
Therefore the port designations for the Quad FXS Voice
ports are
1.1 , 1.2 , 1.3 , and 1.4 .
These port numbers will appear in the front panel LCD
menu displays. The remainder of the manual will refer to
port numbers as
1.1 or X.1 for illustrative purposes.
