I rehomed from old iBSC to new iBSC and MO call and EDGE was working in old BSC whereas old bsc configuration data is loaded in new ibsc but MO call is ok in new bsc and EDGE is not working.
In new BSC its 1st site which was integrated for testing purpose and i am facing the issue.
I am sure you must have checked the GB link and nsvc proper configuration, also check whether there is break at sgsn end and check RAC of the site and whether the same RAC is defined in sgsn
Please make sure your Gb interface config is fine, than check the site configuration on UPPB/DSP and confirm the RAC is correctly configured in SGSN. also please reset the CMB of sites and use channel combination 14 PDTCH in TRX.
i am sure it will work.
