<Guaranteed bitrate UL>: a numeric parameter that 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. +CGEQNEG:…,32, …).
<Guaranteed bitrate DL>: a numeric parameter that 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. +CGEQNEG:…,32, …).
<Delivery order>: a numeric parameter that indicates whether the UMTS bearer shall provide in-sequence
SDU delivery or not.
0 - no
1 - yes
Other values are reserved.
<Maximum SDU size>: a numeric parameter that (1,2,3,…) indicates the maximum allowed SDU size in octets.
<SDU error ratio>: a string parameter that 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. +CGEQNEG:…,”5E3”,…).
<Residual bit error ratio>: a string parameter that 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. +CGEQNEG:…,”5E3”,…).
<Delivery of erroneous SDUs>: a numeric parameter that indicates whether SDUs detected as erroneous
shall be delivered or not.
0 - no
1 - yes
2 - no detect
Other values are reserved.
<Transfer delay>: a numeric parameter (0,1,2,…) that indicates the targeted time between request to transfer
an SDU at one SAP to its delivery at the other SAP, in milliseconds.
<Traffic handling priority>: a numeric parameter (1,2,3,…) that specifies the relative importance for
handling of all SDUs belonging to the UMTS bearer compared to the SDUs of other bearers.
If a value is omitted for a particular class then the value is considered to be unspecified.
Implementation
Optional.

+CGATT= [<state>]
OK
ERROR
+CGATT?
+CGATT: <state>
+CGATT=?
+CGATT: (list of supported <state>s)
Description
The execution command is used to attach the MT to, or detach the MT from, the Packet Domain service. After the
command has completed, the MT remains in V.250 command state. If the MT is already in the requested state, the
command is ignored and the OK response is returned. If the requested state cannot be achieved, an ERROR or +CME
ERROR response is returned. Extended error responses are enabled by the +CMEE command.
