Can see from inside the graph, a multi-frame in PCM30/32 route system includes 16 frame, number isFrame? , Frame...Frame, the time of one multi-frame is 2 millisecond. Each frame (the time of every frame is 125 small seconds) include again have 32 roads time slot, its number is? , the time of every road time slot is 3.9 small seconds. Bag of each time slot contains 8 a time slot, its number is, every time of a time slot is 0.488 small seconds. ?

Road time slot? Convey respectively the 15th letter piles up the 1st ~ , road time slot? Convey respectively the 30th letter piles up the 16th ~ . Occasionally frameDeferent frame synchronization piles up time slot, its pattern of sling-load is {× 0011011} . Pattern of sling-load of time slot of strange frame TS0 is {× 1A1SSSSS} , among them A1 is codes of pair of upright give an alarm, frame synchronization expresses when A1=0, state frame loses a condition when A1=1; S is reserve bit, can use deferent business code; × reserves for international bit or deferent loop are redundant desired result is piled up (CRC piles up) , it can be used at surveillance to be piled up by accident. Frame? Before time slot 4 codes are multi-frame synchronism to pile up, its pattern of sling-load is 0000; A2 breaks a pace to be piled up to accusing for multi-frame. Of frameTime slot is used deferent the letter of 30 telephone channel makes pile up. FrameBefore time slot 4 codes are used deferent the letter of the 1st signal makes pile up, 4 codes are used after deferent the letter of the 16th signal makes pile up... . Until? Frame? Time slot around is piled up 4 times each convey respectively the letter of the 30th the 15th road, signal makes pile up, each telephone channel in a such multi-frame convey by turns respectively the letter makes be piled up. Press a plan 3 - 3 shown frame structures, and basis sampling theory, every frame frequency should be 8000 frame / second, frame cycle is 125 small seconds, is so the total number rate of PCM30/32 route system?
