Setting Considerations
The current service option is determined by the current system type and the current radio configuration.
When a call is being connected, changing the service option for the current radio configuration for the IS-2000 system will be rejected. If the service option is changed for a non-current radio configuration for IS-2000 system, the new value is stored until the associated radio configuration is active.
The test set does not negotiate service options during a call establishing (the call is originated either from the test set or from the mobile station). If the mobile station rejects or tries to negotiate a different service option other than the test set proposed (set by
FCH Service Option Setup
(
F12
) on Call Parms 1 of 4), the test set will generate an error and not establish the call.
For SO1, SO3, SO17, SO68, SO70 or SO32768 connection, the test set will generate data on the forward traffic channel from the specified voice source (see
Voice SO Mode
).
For SO2, SO9 or SO55 connection, the test set commands the mobile station to go into loopback using the specified traffic data rate (see
Traffic Data Rate
).
The SO6 and SO14 are for SMS support.
The SO32 (+F-SCH) and the SO32 (+SCH) are service options primarily used for testing supplemental channel. See
What is a TDSO (Test Data Service Option) FER (Frame Error Rate) measurement?
for details. If a call is established with Service Options SO32(+F-SCH)" or SO32(+SCH), the test set will establish an F-FCH with SO32 service option using a full rate fixed data pattern of all `1's and assume full rate R-FCH (SO32) for the purposes of receiver ranging (the Traffic Data Rate does not apply in SO32(+F-SCH) service option). See
Reverse Traffic Channel Data Rate Determination
. The F-SCH and/or R-SCH is then established with SO32 service option according to the F-SCH and or R-SCH parameters (see
Configuring the TDSO Supplemental Channel Information
).
The SO33 and SO33 (+F-SCH) packet data service options are only available in the lab application. See
Packet Data Service Configurations
for details.
