CBS Timeslots
Each CBS uses two (2) of the 24 available Timeslots to communicate
with the ESLs in its coverage area. Timeslots are assigned in pairs (1,
13; 2, 14; 3, 15; and so forth) to each CBS.
To provide the most efficient communication network, adjacent CBSs
must have timeslots that differ. The optimal difference is 6, but in larger
installations, this may be difficult to accomplish.
The timeslots for the CBSs shown in the Sample Store Cabling
illustration in the previous section could be set as follows to achieve
efficient communications:
CBS Number CBS ID Timeslot ID 1 Timeslot ID 2
