Chapter 2 Introducing the BCM50 hardware
N0027152 01
N0027152 01
The back of the MBM has a single connector that provides signaling channels, media channels,
and power to the MBM. This connector plugs into the MBM backplane in the expansion unit.
Some MBMs also have a cooling fan that runs off the MBM power source.
Figure 6
shows the rear
views of the two types of MBMs.
Figure 6 Media bay module connectors (rear view)
Trunk media bay modules
Trunk media bay modules connect telecommunications lines to the BCM50 system.
Table 3
lists the types of trunk media bay modules that are available for the BCM50 system.
Note:
Refer to
“Regional media bay module availability” on page 231
to determine which
media bay modules and which types of trunk lines are available in your location.

What it does
Special notes
DTM
“Digital trunk media bay module”
Connects digital public switched
telephone lines to the BCM50 system.
Can connect to one of four types of
lines: TI, North American PRI, ETSI
ISDN (E1), and European PRI (E1).
BRIM
“Basic rate interface media bay
module”
Connects a maximum of four ISDN BRI
S/T interfaces.
Refer to
“System region attributes” on
page 229
for supported regions.
GATM4/GATM8
“Global Analog Trunk Module”
Connects either four (GATM4) or eight
(GATM8) analog public switched
telephone lines to the BCM50 system.
Refer to
“System region attributes” on
page 229
for supported regions.
