Reply To: Abrupt nature of SDCCH blocking in n/w

Hi Bijay,

Thanks you very much. Its really works for me.

Just want to clarify the following.

we hv common bcch for 900 & 1800
“In that case all RTSL’s can be configured as TCHD.
“. So it means all 1800 rtsl are tchd.

An expl: In a segment w, say both 900& 1800 exist, with common BCCH in 900. Also 900 has 3 TRX & 1800 has 2 TRX in the same segment under common BCCH.
All TRX lapd are 16 kbps.
So ,

TRX 1 in 900: MBCCH, SDCCB, TCHD,TCHD,TCHD,TCHF,TCHF,TCHF.

TRX 2in 900: SDCCH,TCHD,TCHD,TCHD,TCHF,TCHF,TCHF,TCHF.

TRX 3 in 900: SDCCH,TCHD,TCHD,TCHD,TCHF,TCHF,TCHF,TCHF.

TRX 4 in 1800: all TCHD
TRX 5 in 1800: all TCHD

Does such a config do well with % sdcch blocking? (I hv kept “1 sdcch per 3 tchd max” rule valid)

OR all the 1800 RTSL should be TCHF?

Is there any other parameter other than FRU,FRL?

What are the parameters values to set for minimum % SDCCH Blocking?
MAXRET to 02 from 04? any other?
