Grounding
A "GND" screw is located on the rear panel of each Module. For proper operation and
code compliance, the grounding screw MUST be connected to a known earth ground
using a #18 AWG or larger UL-1015 type copper wire. Note that when using the Main
Cabinet, a separate ground connection to the individual Modules is not required.

In general, PSTN and SLT (telephony) connections are available on the rear of each
Module. LAN, power, and RS-232 connections are on the front of each Module.
Telephony connections are via RJ-11 type jacks wired as in
Figure 3-11. These telephony
jacks are also employed for the miscellaneous functions of the MFIM Module. Details for
the terminations of the miscellaneous function jacks are given in
