Hello Arinze Chidi!

HR/FR is a multiplexing mechanism on timeslot taken by the BSC in other to fit with capacity requirement. This rate change is guided by parameters that enable the BSC to take decision on the rate to set for new incoming calls in a particular cell.
Now half rate is 2 users multiplexed on a single TS every frame and each of them haS his SACCH channel on frame 12 and 25 for MR report purpose, across multiframe26

Currently there are features which support quad rate calls in the system ie 4 simultaneous calls at one time slot.

in Ericsson : it's known as VAMOS feature and in Nokia : it's known as OSC feature.

Ex: 1 TRX=8 tsl

using combined mode we have 7 TCH TSL.

Total Voice calls supported by TRX= 7*4=28 calls simultaneously.
