<Guaranteed bitrate UL>
This parameter indicates the guaranteed number of kbits/s delivered to UMTS (up-link traffic) at a SAP (provided
that there is data to deliver). As an example a bitrate of 32kbit/s would be specified as 32
(e.g., AT+CGEQMIN=...,32,...).
0 subscribed value. Default.
1...63
64...128 (value needs to be divisible by 8 without remainder)
<Guaranteed bitrate DL>
This parameter indicates the guaranteed number of kbits/s delivered by UMTS (down-link traffic) at a SAP
(provided that there is data to deliver). As an example a bitrate of 32kbit/s would be specified as 32
(e.g., AT+CGEQMIN=...,32,...).
0 subscribed value Default.
1...63
64...256 (value needs to be divisible by 8 without remainder)
<Delivery order>
This parameter indicates whether the UMTS bearer shall provide in-sequence SDU delivery or not.
0 no
1 yes
2 subscribed value. Default.
<Maximum SDU size>
This parameter indicates the maximum allowed SDU size in octets.
0 subscribed value. Default.
10...1520 (value needs to be divisible by 10 without remainder)
1502
<SDU error ratio>
This parameter indicates the target value for the fraction of SDUs lost or detected as erroneous. SDU error ratio
is defined only for conforming traffic. The value is specified as “mEe”. As an example a target SDU error ratio
of 5*10-3 would be specified as “5E3” (e.g., AT+CGEQMIN=...,”5E3”,...).
“0E0“ subscribed value. Default
“1E2“
“7E3“
“1E3“
“1E4“
“1E5“
“1E6“
“1E1“
<Residual bit error ratio>
This parameter indicates the target value for the undetected bit error ratio in the delivered SDUs. If no error
detection is requested, Residual bit error ratio indicates the bit error ratio in the delivered SDUs. The value is
specified as “mEe”. As an example a target residual bit error ratio of 5*10-3 would be specified as “5E3”
(e.g., AT+CGEQMIN=...,”5E3”,...).
“0E0“ subscribed value. Default
“5E2“
“1E2“
“5E3“
“4E3“
“1E3“
“1E4“
“1E5“
“1E6“
“6E8“
<Delivery of erroneous SDUs>
This parameter indicates whether SDUs detected as erroneous shall be delivered or not.
0 no
1 yes
2 no detect
3 subscribed value. Default
<Transfer delay>
This parameter indicates the targeted time between request to transfer an SDU at one SAP to its delivery at the
other SAP, in milliseconds.
0 subscribed value. Default
10...150 (value needs to be divisible by 10 without remainder)
200...950 (value needs to be divisible by 50 without remainder)
1000...4000 (value needs to be divisible by 100 without remainder)
