When you address a tone-carrying time slot on the TDM bus (A or B) that is

tones. Time slots 000-004 and 256-260 carry c ontrol information and are not
addressable. Time slots 254 and 510 are not addressable d ue to a hardware
constraint. At any given time, only one of th e TDM busses (A or B) carries the
dedicated tones, with B being the default. Entering status port-network will
display which TDM bus is currently carrying the dedicated tones. The
corresponding t ime slots on the other bus are normally inactive and are used for
call service only as a last resort w hen all other non-control channel time s lots on
both busses are busy. Bus A’s tone time slots are numbered 005 -021; bus B’s
tone time slots are numbered 261-277.
Reorder tone The time slot is in use, the time slot is not
addressable, or inter-PN resources are not

that any noise may be heard.
