DS0 MAPS > EDIT/VIEW MAP 2 > PORT
When you select this option, a list of ports appears. Pick the appropriate port and press <Enter>. The
selection list shows only the remaining ports available to be assigned. It may be necessary to unassign a
port in order to reassign it elsewhere.
Once a
SERVICE is assigned, the choices are module-dependent. For the FXS, the port choices are
UNASSIGNED, and PORTS 1-24. For the TA IAD, the port choices are UNASSIGNED, ROUTER 64K, ROUTER
56K, V.35 64K,
and V.35 56K. Default is N/A.
DS0 MAPS > EDIT/VIEW MAP 2 > RBS
Robbed Bit Signaling. Default is N/A. Once a service and port are assigned, this will automatically change
to
ON or OFF. The unit will automatically assign OFF where RBS is not an option. ON preserves the
signaling bits between the connections.
OFF ignores the signaling bits. For the FXS, RBS defaults to ON.
The
RBS parameter remains at N/A for the TA IAD because RBS is not applicable to data
communications.
