Patch Set 3:

As described in 44.060 section 11.2.5 the packet channel request is sent using PRACH uplink block format. As PRACH is not supported, hence setting access_burst_type has no effect in GPRS. In case of GPRS it always uses 8 bit RACH.

As described in 44.060 section 11.2.5a the EGPRS packet channel request is sent using PRACH uplink block format or on the RACH. hence 11 bit is supported in case of EGPRS.
