This document contains parameters related to 2G cell configuration for an Axis network with 2247 sites and 19 BSCs. It includes common cell data parameters like AGBLK, MFRMS, ACCMIN, INDOOR_CELL values. It also includes locating cell filter data parameters like BSPWR, BSTXPWR, MSRXMIN, BSRXMIN for path loss calculation. Finally, it contains locating urgency cell data parameters like TALIM, PSSBQ, PTIMBQ, QLIMDL for handling call quality issues. The parameters need to be optimized for Axis' coverage-limited network.

AGBLK : 1 ; 8 CCCH blocks in each multi frames and possible to have 16 to 72 Paging Group
A high number of paging groups means that the mobiles have to wait for a longer time than the low
number case before the right paging block arrives. This increases the time for paging. It also
reduces the paging capacity compared to using fewer paging groups. This is because with a high
number of paging groups, each paging group will have a short paging queue in the BTS.
