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.
