For maximum backup capability the control channel can be assigned to a voice channel
during setup. For example, if the TRX with the primary MVC control channel is taken out
of service, the back up or secondary MVC on the third TRX is activated.

Total analog voice channels: 3
An analog gateway cell with two radio heads and two EMRPSs uses six time
slots to support six voice channels.
A Dual Mode Cell with Two Radio Heads and Two EMRPSs: Pico 850 MHz
The dual mode cell (IS-54B and IS-136) uses an analog control channel and
provides both digital and analog voice channel capabilities. Handoffs from
analog and digital voice channels are supported. This type of cell generally
requires two Radio Heads and two EMRPSs because of the number of control
(non-voice channel) functions required to support analog and digital modes.
The Radio Head TRXs in this cell configuration support the channel
functions shown in Table 5-11 on page 5-40 and Table 5-12 on page 5-40.
Note: Each DVC supports three digital voice channels using one
time slot. A DCCH can be combined with two DVCs on the
same TRX.
