3.17 SERVICE CHANNEL CONNECTIONS
A service channel is defined as a non-revenue bearing channel provided as part of a trans-
mission system for operation, maintenance, monitoring, and control of the system. The
MDR-8000 provides a 256 kb/s auxiliary channel for servicing the radio. This is an over
-
head channel and is independent of the traffic channels. The 256 kb/s service channel con-
tains four 64 kb/s service channels. Three of the four 64 kb/s channels (Service Channel 1,
2, and 3) can be provisioned on the USI for a specific use. Service channel 4 is dedicated to
radio commands and ELMC. Service channel is not provisionable. The four channels are
multiplexed and shifted in and out of registers on the controller.
See Figure 3 - 23. There are eight connectors on the backplane to interface with three of the
service channels. The connectors on the backplane interface three functions: audio, RS-
232, and MCS-11. Each service channel is provisioned for a specific function. As shown by
the vertical line connecting to the three functions on one side and the three service chan
-
nels (SC1, SC2, and SC3) on the opposite side, audio and MCS can be put on any open ser-
vice channel. RS-232 data can be put on service channel 1 or 2 but cannot be put on service
channel 3. This is shown by the dashed lines to the specific service channel.
3.17.1 2-Wire Handset Connection
The 2-wire port at the TEL connector on AE-37Y Controller accepts either the optional
handset, listed under equipment supplied in the General section, or a standard telephone.
The 2-wire port is not provisionable and should not be confused with the 4-wire provision
-
able parts (Audio 1 and Audio 2). To use the handset, the radio must be provisioned for
Audio 1.
