This is the most mysterious rule from Alcatel. I’ve been staring stupidly at this rule for years, and it still dosn’t make any sense at all. On top of that, it is said that this rule is based on 3GPP recommendations !
As I said before, the TSC is a sequence of bits used to compute the rxqual. I’ve read that some TSC sequences are better for that purpose than others, but that was in case of 8PSK EGPRS. I have no idea if that’s the idea behind this rule or not.
I must admit, I gave up 🙂
