ABSTRACT:
The invention relates to a method for finding frame alignment and accepting and monitoring TTI identifiers contained in frames in an SDH system. Advantageously the method according to the invention comprises steps in which frame alignment is first sought for by means of a frame alignment signal. When frame alignment has been found, it is monitored that it stays correct and at the same time at least one TTI identifier is read. According to the invention, at least one TTI identifier is saved from a frame after the finding of frame alignment. If a loss of frame alignment is detected, the TTI identifier saved is stored for a predetermined time. The invention further relates to an arrangement comprising means to implement the method described above in an SDH system.
