For this command the <maxAiur> and <modify> values depend on the product. (GSM
07.07 section 6.14.)

Non-transparent call configuration. The
default option is 0, 0, 0, 0.

Query current setting.
Response is +CHSN: <wAiur>, <wRx>,
<topRx>, <codings>

Show supported values.
Response is +CHSN: <wAiur>, <modify>

Parameters
<wAiur>: integer type; wanted air interface user rate. Default value 0 indicates that
TA shall calculate a proper value from currently selected fixed network user rate
(<speed> subparameter from +CBST command), <codings>, and <wRx> (or
<maxRx> from +CHSD command if <wRx>=0).
Other values:

9600 bps

14400 bps

19200 bps

28800 bps

38400 bps

<wRx>: integer type; wanted amount of receive timeslots. Default value 0 indicates
that TA shall calculate a proper value from currently selected <wAiur> and <codings>

<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

<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)

<maxAiur>: integer type; maximum value for <wAiur> (assuming that all supported
channel codings are accepted and maximum number of timeslots are used)

<wAiur>/<wRx> modification during call is
not supported by ME/TA (<topRx>
accepts only 0)

<wAiur>/<wRx> modification during call is
supported by ME/TA

This command hangs up the call, also when an alternating mode call is active. This is
an assured procedure to terminate an alternating mode call. (GSM 07.07 sections
6.5, 6.6, and annexes E, F).

Hang up call. Response is OK.

Shows whether command has been
implemented.
