DS1 clocks are not required to be synchronized, they are interleaved into DS3 with lossless bit-stuffing. When there is a loss of frame sync, signalling channels are inhibited. There's no transient synchronization recovery condition where channels are misaligned, the frame sync must be recovered first, and when it's recovered, all channels are correctly aligned. I used to design this equipment. I'm afraid this explanation is not correct. |
