Through this analysis the major principles that I have understood are given below.

1.     ACC-Access Control Class Feature introduced to control various Mobile users access in to GSM Network. The same is extended to 3G/4G.

2.    Normal Customers are programmed with Access Class 0-9 and allowed in HPLMN/VPLMN

3.    PLMN Team/Staffs are programmed with Access Class 11/15 allowed Only in HPLMN.

4.    Access Class 12/13/14 allowed to roam in HPLMN & VPLMN. (No MCCMNC Check)

5.    Some MS/UE Vendors manufacture their equipment to support only ACC-0 to 9.

6.    EFACC – A 2 byte information stored in each SIM’s ROM which will be transferred to MS/UE when it is powered on. Ref : 3GPP TS 22.011

7.    System Info Type 3 (GSM/WCDMA) broadcasted from the network will carry the barred class info.In case of LTE/LTE-A it will be System Info Type 2

Anyway I have re-posted it here... for everybody's reference...
