CDMA cluster contains 14 CEs, and a fully loaded CDMA radio shelf
contains 28 CEs.
A CE contains the necessary circuitry to support one CDMA channel. It
can be configured as an overhead channel (pilot/sync/access or page) or a
traffic (voice) channel.

BCR-BIU-ACU (BBA)
A baseband combiner and radio (BCR) and its associated bus interface
unit (BIU) and analog conversion unit (ACU) form a CDMA radio set—the
BBA (for BCR-BIU-ACU). Because the BBA is a single point failure for a
sector, redundant BBAs—one active and the other in standby mode—may
be installed for increased reliability. (A BBA pair is redundant.) For OA&M
purposes, the BBA is treated as a single maintenance unit.
The
2138
page shows the following information for each CCC:
■
Number of channel elements (CEs) out-of-service
■
Associated packet pipe (PP) trunk group member.
The
2138
page shows the following information for each BBA pair:
■
Assigned CDMA channel (carrier) number
■
Associated physical antenna face (PAF).
In addition, the
2138
page shows the identity of the serving DCS, packet pipe
trunk group, and the Global Positioning System (GPS) alarms status.
