support for Ericsson RBS E1 CCU
Ericsson RBS series BTSs do not have a built in PCU. Rather than having
the PCU on board the PCU is co-located to the BSC in those cases. Just
like the MGW the PCU would connect to the CCU (Channel Coding Unit) via
E1 line. The PCU is connected via an unix domain socket (pcu_sock) to
the BSC to receive RACH requests and to control Paging and TBF assignment.
This patch adds all the required functionality to run an Ercisson RBS in
GPRS/EGPRS mode. It supports 16k I.460 E1 subslots and full 64k E1
timeslots (recommended)
