Channel Selection drop down list is used to select between the Preferred and Exclusive B
channel selection methods. For Preferred channel selection, the CO answers to the call re-
quest by the first available timeslot, while for Exclusive channel selection CO should feed-
back only by the timeslot used for the call request.
Channel Selection Ordering drop down list is used to choose the B channels selection
(Ascending or Descending). When Ascending selection is configured, B channels will be
defined starting from B1 to B23/B30. For Descending selection, B channels will be defined
from B23/30 to B1. If your CO/PBX has Ascending B channels selection configured, it is
recommended to use Descending B channels selection and vice versa.
Please Note:
A timeslot can be used either for voice or data transfer. The system prevents
selecting a timeslot from the B channel list if it has already been selected from the D Chan-
nel receive/transmit drop down list.
