Each RC supports traffic channels of different data rates. The capability of the
CDMA2000 1X system varies with RCs. For example, the CDMA2000 1X system with
RC1 and RC2 is compatible with IS-95A/B.

4.4 Channel Configuration

A series of physical channels are defined on the Um interface. These physical channels
are classified by channel features.

4.4.1 Forward Channels

Forward channels include forward common channels and forward dedicated channels.
I. Forward Common Channels
Forward common channels are further divided into:
Forward pilot channel (F-PICH)
F-PICH provides synchronization signals to the MSs operating in the BTS coverage.
Different from other channels, the F-PICH is an unmodulated spread spectrum signal
that is always in the transmit state.
Forward synchronization channel (F-SYNCH)
F-SYNCH provides initial time synchronization information to MSs operating in the BTS
coverage.
Forward paging channel (F-PCH)
F-PCH sends overhead messages and MS-specific messages to the MSs operating in
the BTS coverage. Each CDMA channel in a sector supports seven paging channels at
most.
Forward quick paging channel (F-QPCH)
The BTS uses the F-QPCH to send the paging order and system configuration change
order to slotted-mode MSs, instructing them to receive the paging messages. This
helps save the MS battery energy.
Forward common control channel (F-CCCH)
The BTS uses the CCCH to send overhead messages and MS-specific messages to
the MS.
II. Forward Dedicated Channels
Forward dedicated channels are further divided into:
Forward dedicated control channel (F-DCCH)
F-DCCH carries traffic information and signaling messages between the MS and the
BTS/DBS.
