Chsn Hscsd Parameter Command Syntax - Nokia 30 GSM Connectivity Terminal At Command Manual

<maxTx>: integer type; the maximum number of transmit time slots that the ME can use
<sum>: integer type; the total number of receive and transmit time slots that the ME can
use at the same time (per TDMA frame). The following applies in a HSCSD call:
1 ≤ (receive slots) + (transmit slots) ≤ <sum>
<codings> a sum of integers, each representing a supported channel coding

6.3.12 +CHSN HSCSD Parameter command syntax

Command
Execute +CHSN=[<wAiur>[,<wR
x>[,<topRx>
[,<codings>]]]]
Test +CHSN=?
The set command controls parameters for non-transparent HSCSD calls. Changing <topRx>
or <codings> value during a call does not affect the current call. Changing <wAiur> or <wRx>
affects the current call only if <topRx> was non-zero when a call was established.
Defined values
<wAiur>: integer type; desired air interface user rate. The default value 0 indicates that
the TA shall calculate a proper value from the currently selected fixed network
user rate (<speed> subparameter from +CBST command), <codings>, and
<wRx> (or <maxRx> from +CHSD command if <wRx>=0). Other values:

6
<wRx>: integer type; desired amount of receive time slots. The default value 0 indicates
that the TA shall calculate a proper value from the currently selected <wAiur>
and <codings>
<topRx>: integer type; top value for <wRx> that the user is going to request during the
next established non-transparent HSCSD call. The default value 0 indicates that
the 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. The default value 0 indicates that all the supported
codings are accepted (refer +CHSD command for other values)
