7.4 AT+CHSR HSCSD Parameters Report
With this command enabled, the intermediate result code +CHSR:
<rx>,<tx>,<aiur>,<coding> is returned (from TA to TE) when an
HSCSD call is being set up. The result code represents the current
(negotiated or renegotiated) HSCSD parameters. If enabled, the
intermediate result code is transmitted at the point of the call setup
negotiation, where the ME/TA has determined what type of HSCSD
connection will be used. Result code transmission is done after possible
service (CR), error control (+ER), and/or compression (+DR) reporting,
but before possible TE-TA rate (+ILRR) reporting and before the
intermediate result code CONNECT is transmitted. The format of the
intermediate result code is:
+CHSR: <rx>,<tx>,<aiur>,<coding>
For the value definitions, refer to “AT+CHSC HSCSD Current Call
Parameters”, page 123. For instance, for a non-transparent HSCSD call,
result code ‘CHSR: 2, 1, 4, 8’ means that the call has two timeslots
<topRx> Description
0 Indicates that the user is not going to change <wAiur> and /or <wRx>
during the next call
1 Top value for <wRx> that user is going to request during the next
established non-transparent HSCSD call is 1
2 Top value for <wRx> that user is going to request during the next
established non-transparent HSCSD call is 2
<codings> Description
4 Indicates that the accepted channel coding for the next established
non-transparent HSCSD call is 9.6kbit/s only
