Cell reselection parameter indicator, indicates the presence of C2
cell reselection parameters on the BCCH
The criterion C2 is an optional feature that can be enabled on a cell
basis. It is an enhancement of the cell selection C1 (for C1 please
see parameter CELLRESH). C2, however, is useful for microcell
configurations since it prevents fast moving MSs from performing
unnecessary cell reselections.

reselection parameters are broadcast (Y) (1)

will be ignored.

AMR Packing / unpacking HO
Channel Mode Adaptation is an HO algorithm that aims at select the correct
channel rate (FR or HR).
The selection of the channel rate depends on 2 main factors: load and
quality
compression/decompression in BR is the same as packing / unpacking in BSS
In BSC3i AMR compression decompression
HO is called packing and unpacking
respectively
