After editing Map A, press
tings and activate the selection fields for Map B. Use the
same operation to edit switching time for Map B.
When ESF is used with an FDL channel between units,
the units automatically coordinate the automatic map
switch by sending a map switch command from end-to-
end over the FDL. Only one end needs to be set to A
for this to work.
This menu item controls the DS0 map the TDU 120e uses
and displays the map in current use.
The DS0 maps designate which DS0s are assigned to
which port. The three maps are:
DS0 Map A
Default map.
DS0 Map B
Alternate map.
Temp
