set tdm
set tdm port-network PN# bus a | b [override]
This command determines which of the paired TDM buses (A or B) on a port
network will carry the control channel and dedicated tone time slots. Each port
network has a 512 time-slot TDM bus configured as two separate 256 time-slot
buses. This division allows for duplication of control channels and time slots
dedicated for use by system tones. On power-up, the control channel is carried
on the A bus, and the tone time slots are carried on the B bus. Execution of this
command puts both the control channel and the tone time slots on the specified
bus.
Under extremely heavy traffic load, tone time slots on the bus that is not currently
carrying the tones may be used for call processing. Use of the override command
under these conditions will cause calls to be dropped.
See ‘‘TDM-BUS (TDM Bus)’’ on page 8-1588 for details.
