A CCC and up to seven CCUs form a CDMA cluster. Each CCC terminates the
dedicated packet pipe (PP) associated with its CDMA cluster.
Each CCU contains two channel elements (CEs); thus, a fully loaded 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), a traffic (voice)
channel, or—for testing purposes—an orthogonal-channel noise simulator
(OCNS) channel. OCNS-configured CEs are used to generate radio signals that
simulate the effect of multiple users operating in a specified sector on a specified
CDMA carrier, so that CDMA system capacity can be estimated in the presence of
actual electrical noise from the environment.
The

Mode (personality of CE)
■
Associated physical antenna face (PAF)
■
Associated CDMA carrier number

Blocking (if any) of the CDMA cluster/ packet pipe.
