The provider-specific GPRS access parameters for two different network
operators can be saved in parameter classes 60 and 61. Based on the IMSI
of the inserted SIM card, the firmware automatically detects the GSM Net ID
(first 5 digits of the IMSI) of the relevant provider and searches for this GSM
Net ID in parameter classes 60 and 61. When they are found, the
parameters contained in the corresponding class are used.
In the factory configuration these two classes are assigned with the GPRS
access parameters from T-Mobile (class 60) and Vodafone (class 61).
Length of the class 6* data sets:
Factory configuration:
The factory configuration of class 60 (C60) and class 61 (C61) is shown in
bold.
Both parameter classes include a range that is reserved for possible
expansions. Parameter expansions that are covered by these reserved
ranges do not lead to any incompatibility between different firmware
versions. If the expansion space is not sufficient, a new parameter class
must be created. This likewise does not lead to any incompatibility, because
a command to set/read this new parameter class from an older firmware will
be acknowledged with ERROR. The reserved parameter ranges are filled in
with '0' (0x30) during communication.
