1-4 Nx56/64 (EIA-530) Option Module User Manual 61200054L2-1
Physical Description
The Nx56/64 (EIA-530) is an option module which plugs
into the option slot in the rear of the TSU product family.
See Figure 1-1.
Figure 1-1. Nx56/64 (EIA-530) Option Module
The rear panel of the option module includes a plastic
plug over a cutout for a second EIA-530 connector. This
allows the addition of another plug-on module. The port
X.1
and
X.2
indication is linked to the port numbering
philosophy of the TSU 100 product family. The
X
repre-
sents the slot number, into which the option module is
plugged. For the TSU 100, there is only one option slot.
Therefore, the port designation would be
1.1
. If a plug-on
(EIA-530) is present, then the part designation would be
port
1.2
. In a TSU 600 with six option slots, these port
numbers would be port
1.1
to port
6.1
. The numbers ap-
pear in the front panel LCD menu displays.
