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 as follows:
• Time slots 005 – 021 and 261 – 277 (bus A) are reserved to carry the system's dedicated tones.
• Time slots 000 – 004 and 256 – 260 (bus B) 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
tones. The corresponding time slots on the other bus are normally inactive and are only used for call
service, as a last resort, when every other non-control channel time slot on both busses is busy.
