Hi Optim,
“INSUFFICIENT EGPRS EQUIPMENT” will pop up when one or both of the following are true:
1. You have not defined the required number of abis timeslots
2. You have not opened the required DCP2s (8 on the EDGE TRX).
Here’s the calculation for your 6/6/6/ site.
i) Total number of radio TRXs = 18
ii)Total number of timeslots = 18*8 = 144
iii) Total Number of TCHs = 144 – 9(3SDs per sector *3) -3(BCCHs)= 132
iv) Total Number of Abis timeslots required for voice (TCHs) = 132*1/4 = 33 (remember each TCH requires 16kbps on the abis, which is 1/4 of the abis timeslot).
v) Total Number of abis timeslots for signalling = 18/2 =9 (18 being the total number of TRXs, 2 being your CONFACTOR).
Number of abis timeslots: Not given
TOTAL NUMBER OF ABIS TIMESLOTS NEEDED = 33+9 = 42.
Remember, however, that this excludes the number of EDGE timeslots, which you did not provide.
Regards
