Hello,
SDCCH Abis Fail is not part of alcatel indicators, which are the only ones I know…
so I cannot help sorry
I don’t know what it means… SDCCH Abis fail… Perhaps the link Abis is down, or perhaps the LapD (RSL) is only “congested”.
Your CSSR might use a formula that is not taking SDCCH failures into account.
Regards
