Figure 5-6. Inband Remote Configuration
INBAND
Inband Configuration Channel - Use to enable/disable an 8-kbps remote
configuration channel (see Figure 5-6). When this option is set to
O
N
, the first DS0
occupied operates in 56K mode and the DTE clock rate is reduced by 8 kbps. The
TSU ACE uses this 8-kbps channel to send and receive configuration data across a
T1 span. As shown in Figure 5-6, this feature allows the PC connected to the Chain
In port on a TSU unit with a Chain In port (TSU A) to monitor and configure both
itself and the TSU ACE.
This feature is useful when FDL connectivity is not available across the T1 span.The
8-kbps channel is only taken out of the first DS0. Therefor, if two 64K DS0s are
mapped, the DTE rate would be 120 kbps instead of 128 kbps.
This menu option can also be set to
A
UTO
which activates the Inband Channel only
when commands are sent from T-Watch PRO to the remote unit (TSU ACE in
Figure 5-6). If no T-Watch PRO activity is detected for 10 minutes, the Inband
Channel is deactivated.
