sponding speech coder source bit-rates are 8550 bps, 4000 bps and 800 bps. Service
Option 3 meets the requirements described in 3GPP2 C.S0014.
The FCH can be configured as follows:
●
FCH sets the radio configuration to use for the Forward and Reverse Fundamental
Channel (F-FCH-RC and R-FCH-RC). The Multiplex Options (F-FCH-MO and R-
FCH-MO) are not selectable; they are set to 1 by the Service Option 3 selection.

Service Option 17
Service Option 17 provides an enhanced variable rate, two-way speech service to the
mobile station using the Forward Fundamental Code Channel with Multiplex Option 1.
Service Option 17 meets the requirements described in 3GPP2 C.S0020.
Service Option 68
Service Option 68 known as EVRC-B provides an enhanced variable rate, two-way
speech service to the MS using the Forward Fundamental Code Channel with Multi-
plex Option 1. This service option communicates at one of four channel rates corre-
sponding to the 9600 bps, 4800 bps, 2400 bps and 1200 bps frame rates. The corre-
sponding speech coder source bit-rates are 8550 bps, 4000 bps, 2000 bps and 800
bps. Service Option 68 meets the requirements described in 3GPP2 C.S0014.

Service Option 70
Service Option 70 known as EVRC-WB provides an enhanced variable rate, two-way
speech service to the MS using the Forward Fundamental Code Channel with Multi-
plex Option 1. This service option communicates at one of three channel rates corre-
sponding to the 9600 bps, 4800 bps and 1200 bps frame rates. The corresponding
speech coder source bit-rates are 8550 bps, 4000 bps and 800 bps. Service Option 70
meets the requirements described in 3GPP2 C.S0014.
