Of course there are many channels in a cell sector, but this does not change
the fact that a single channel will always have 8 physcial timeslots (even
half-rate cells operates on 8 physical timeslots per frame per channel,
expect in half-rate mode each "circuit" will transmit on every other frame).
In the infrasturture industry a BTS rack can normally accomdate several
radios (and hence several channels), but the term BTS is normally used to
discribe a single radio/channel hence leading to phrases like BTS2, BTS6
etc.

You mean not used - the timeslots are always there in the basic structure
whether they are used or not.

No, you are technically incorrect, I am sorry there is always 8 timeslots
per channel, they may not all be used for voice or data, and some may be
used for broadcast or control channels, but the timeslot structure is always
8 per frame. |
