Reply To: SPDCH


With regard to abis allocation, there is no difference between SPDCH and FPDCH. Both are allocated fixed timeslots if you’re using a fixed scheme or dynamically if you’re using flexible abis. The only difference between SPDCH and FPDCH relates to how they are treated on the PCU. The PCU allocates fixed resources (GSL) for FPDCH and on-demand resources for SPDCH.
