set tdm
set tdm port-network PN# bus a | b [override]
This command determines whic h of the paired TDM buses (A or B) on a p ort
network will carry the control c hannel and dedic ated 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 us e by system tones. On power-up, the c ontrol channel is carried
on the A bus, and the tone time slots are c arried on the B bus. Execution of this
command puts b oth the control channel and the tone ti me slots on the specified
bus.
Under extremely heavy traffic load , tone time slots on the bus that is not currently
carrying the tones may b e used for call proc essing. Use of the override
command under these c onditions will cause c alls to be dropped .
See TDM-BUS in Chapter 9 for details.
