2.2.6.2. Displaying the B Channels currently Available/Configured
(possible IP-Based Connections) 
The total number of B channels currently in use is shown as usual
in the AMO BCSU. The number of B channels is configured in AMO BSCU with
the corresponding B channel parameter for each function (BCHL3530,
BCHLSIP, BCHL3550, BCHLWAML and BCHL3570).
The AMO BFDAT includes the parameter BRDBCHL. This defines the
maximum number of B channels for the board (60 or 120 B channels).
Using the AMO BCSU, you can query the number of B channels available
for the common gateway board. The AMO UCSU must be used for configured
HG3575 boards.
IMPORTANT:
Determination of the B channel values differs
for HG 3500 and HG 3575.
You can check the channels or bandwidth used with the AMO GKTOP following
appropriate configuration.
DISPLAY-BCSU:TAB,1,<LTU Number>; command shows
3 b-channel values:- The maximum number of B-channels supported by the board,
- the number of used b-channels per function and
- the maximum possible number of b-channels per function.
