[RPRWG] My Apologies
Dear All.
Well i have just joined the group, not knowing the business rules, i asked for
some help. I hope this clearifies the issue on my part.
However my technical query remains unanswered .... "Can we discuss the
performance issue for GSM networks over RPR Metro rings, in this Reflector???"
Regards
Osman
