Pix can u help 17th January 2011 at 09:55 #65519 PixGuest 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.
