Does the MSPD follow incoming increments and decrements?
Yes. All incoming inc’s and dec’s are followed. Note that if incoming inc’s dec’s are greater than the SONET required 1 per 4 frames maximum, the MSPD will observe the incoming inc’s and dec’s, but will generate outgoing inc’s and dec’s according to the SONET standard, unless the user requests an override. Thus, for example, if a path is observed to get an inc every 2 frames (1 inc every 2nd frame), the outgoing path will generate an inc every 4 frames, and extra inc’s will get put into a queue. If 10 incoming inc’s are received, 10 outgoing inc’s will be generated, but spaced at a minimum 4 frames apart.
