4x16 wiring charts

You can connect up to 4 analog telephone lines and up to 16 digital telephones to the 4x16 media bay module (MBM).

The analog telephones lines are connected to the 4x16 through the RJ-11 jacks (labeled 1 to 4) on the front of the MBM. Do not connect analog telephone lines to the auxiliary jack on the front of the media bay module. These jacks are intended for analog telephones designated as emergency telephones. See Figure 86.

The digital telephones, such as the Business Series Telephones, are connected to the RJ-21 connector on the front of the 4x16.
