The E&M+ is an option module which plugs into the op-
tion slot in the rear of the TSU 100/120/600.
See Figure 1-1.

Figure 1-1. E&M+ Dual Voice Option Module
The E&M+ option module rear panel includes a plastic
plug over a cutout for additional connectors. This allows
a plug-on board to be added to the E&M+ option module.
The PORT X.3/X.4 indication is linked to the port num-
bering philosophy of the TSU 100/120/600 product fam-
ily. The X represents the slot number, and the .3 indicates
the port number.
For the TSU 100/120/600 application, there is only one
option slot. Therefore the port designations for the two
E&M voice ports are 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 LCD menu displays.
