8.3.10 +CHSR HSCSD parameters report
Command
set
+CHSR=<mode>
read
+CHSR?
test
+CHSR=?
Mandatory when HSCSD is implemented. 07.07 section 6.16.
8.3.11 +CHSD HSCSD device parameters
Command
execute
+CHSD
test
+CHSD=?
Mandatory when HSCSD operation is implemented. 07.07 section 6.12.
Parameters:
<mclass>:
integer type; multislot class
<maxRx>:
integer type; maximum number of receive timeslots that ME can use
<maxTx>:
integer type; maximum number of transmit timeslots that ME can use
<sum>:
integer type; total number of receive and transmit timeslots that ME can use at
the same time (per TDMA frame). The following applies in a HSCSD call: 1 <=
(receive slots) + (transmit slots) <= <sum>
<codings>
is a sum of integers, each representing a supported channel coding (e.g. value
12 indicates that 9.6k and 14.4k channel codings are supported):
1
4.8k full rate data traffic channel
4
9.6k full rate data traffic channel
8
14.4k full rate data traffic channel
