Hi Safar,
Abis Optimization: Abis Optmizer is a tool where there is no concept of TS for TRX. All will be sent by packetising the same. Hence the capcity would be increased fom 12TRX max to 20TRX with 1E1. Also, we need not allocation for any dedicated TS for EGPRS. There will be a pool where in data is transferred to any sector.
As usual somebody correct if am wrong.
