4X16 media bay module
(North American systems only)
The 4X16 provides both analog trunk connections and connections to digital telephones. The
module is a combination of a CTM media bay module, with four analog lines, and a DSM
16-digital telephone media bay module. Each of the four ports supports Caller ID and disconnect
supervision. An auxiliary port beside Line 1 allows you to use an analog telephony device, such as
a modem, fax or telephone, to share the trunk.
Figure 32 shows a diagram of the 4X16.
The 4X16 has one amphenol connector and five RJ11 connectors on the faceplate. For details on
the 4X16 wiring, refer to
Chapter 13, “Installing Analog Terminal Adapters,” on page 217 .
