DEF CH X command. To reassign time slots currently assigned to the

Replacing a Time Slot Used for In-band Management
Before selecting a new time slot for the main link in-band management, you
must close the current dedicated time slot.
1. Close the time slot used for the in-band management with the DEF DL

command.

Wait 20 seconds (40 seconds if H-RPT is installed in the HDSL link).

Note

Make sure that the time slot, which you intend to use for the in-band

management is not assigned to a data channel or sublink.
2. Assign the desired time slot to the in-band management, using the DEF

DL command.
