4.4.5 B Channel Status
Active B channels may need to be taken out of service periodically for testing or maintenance
by the user or the carrier. Choosing the “sTatus” option from the "Bmap" screen not only
allows the user to execute these options for individual B channels on an active D channel, but
also to review changes made by the carrier. Highlight the specific B channel and press the
command option in the Menu of Actions to perform the desired action. Lower case letters
signify changes made by the user; capitalized letters show carrier changes.
In Figure 4-15, B Channels on time slots 6-7 on WAN 1-1 are placed in an Out of Service
condition, and B channels on time slots 16-17 on WAN 1-2 are placed in maintenance mode
by the user. B channels on time slots 8-9 on WAN 1-1 are in maintenance mode by the carrier,
and B channels on time slots 6-9 on WAN 2-2 are out of service by the carrier. Users and
carriers can only reinstate B channels taken out of service or placed in maintenance mode by
themselves.
