2. Dial the 2-digit port network number followed by # and the 3-digit time slot
number listed in the following table.
3. Listen for one of the following tones:
TDM Bus Time Slots
When you address a tone-carrying time slot on the TDM bus (A or B) that is
currently carrying tones, you will be connected to that time slot and will hear the
tone.
Time slots 005-021 and 261-277 are reserved to carry the system’s dedicated
tones. Time slots 000-004 and 256-260 carry control information and are not
addressable. Time slots 254 and 510 are not addressable due to a hardware
constraint. At any given time, only one of the 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 time slots on the other bus are normally inactive and are used for
call service only as a last resort when all other non-control channel time slots 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
available to make the call.
Confirmation tone The time slot is idle or out-of-service. The time
slot may be on the TDM bus (A or B) that is not
currently carrying tones, or it may be busied
out. The call is connected to the time slot so
that any noise may be heard.
System tone The time slot is carrying a system tone as listed
in the following table.
