Release 6
<topRx>: integer type; top value for <wRx> that user is going to request during the next established non-
transparent HSCSD call. Default value 0 indicates that user is not going to change <wAiur>/<wRx> during the
next call. This parameter is not applicable to UTRAN single mode UE.
<codings>: a sum of integers each representing a channel coding that is accepted for non-transparent HSCSD
calls. Default value 0 indicates that all supported codings are accepted (refer +CHSD command for other values).
This parameter is not applicable to UTRAN single mode UE.
Implementation
Mandatory when non-transparent HSCSD implemented.
6.15 HSCSD current call parameters +CHSC
Table 22: +CHSC action command syntax
Command
Possible response(s)
+CHSC
+CHSC: <rx>,<tx>,<aiur>,<coding>
+CHSC=?
Description
Execution command returns information about current HSCSD call. If no HSCSD call is active, all parameters returned
shall equal zero. If HSCSD call is active in UTRAN, all non-applicable parameters returned shall be equal to zero. (It is
manufacturer specific whether non-zero information is returned in case of an active normal single-slot data call.)
Defined values
<rx>: integer type; number of receive timeslots currently in use. This parameter is not applicable in UTRAN.
<tx>: integer type; number of transmit timeslots currently in use. This parameter is not applicable in UTRAN.
<aiur>: integer type; current air interface user rate (in case of transparent service this equals fixed network user
rate) (refer +CHSN command for possible values). For the two-timeslot ECSD bit transparent configuration the
following additional values apply:
8 56000 bps
9 64000 bps
<coding>: current channel coding (refer +CHSD command for possible values). This parameter is not applicable
in UTRAN.
Implementation
Optional.
