Frame Slips
Digital signals must have accurate clock synchronization for data to be
interleaved into or extracted from the appropriate timeslot during
multiplexing and demultiplexing operations. A Frame Slip is defined (for 2.0
Mb links) as the repetition of, or deletion of the 256 data bits of a CEPT frame
due to a sufficiently large discrepancy in the read and write rates at the buffer
(clocks are not operating at exactly the same speed).
When data bits are written into (added to) a buffer at a slightly higher rate
than that at which they are being read (emptied), sooner or later the buffer
overflows This is a slip-frame deletion.
