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.

5.6.4 RBS 884 Pico Cell Configuration Examples: Pico 850 MHz
The following examples apply only to the 850 MHz product. The 850 MHz
product is not limited to the following configurations; but can use anywhere
from one-EMRPS to eleven-EMRPSs in a configuration.
5.6.4.1 Four EMRPS: Pico 850 MHz
A four-EMRPS Pico 850 MHz configuration uses one XLI board, regardless
of the channel functions provided, since there is a one-to-one correspondence
in the number of EMRPS boards and Radio Heads. One ETB board is
used and may be either a 24 time-slot T1 version or a 32 time-slot E1
version. The CRI subrack layout for this configuration is shown in Figure
5-7 on page 5-41.
