However, the all-ones alarm indication is not cleared in all the path-processing slices until 10 frames after the enabled NDF appears. Therefore, the payload and concatenation indicators will be temporarily corrupted. After 10 frames, a valid pointer (with no enabled NDF), payload, and concatenation indicators are output on the Drop bus. The transition from PAIS to valid data cannot be easily detected without monitoring overhead.

The TIU2PERDI bit is not defined in the SPECTRA-622 device. Path enhanced RDI assertion due to path trace identifier (mode 1) unstable (TIU) events is enabled via the TIUPERDI bit only (register 0119H). The description of the TIUPERDI bit has not changed, and reads: ett io TIUPERDI: inv ef uo fo liv When set high, the TIUPERDI bit enables path enhanced RDI assertion when path trace identifier (mode 1) unstable (TIU) events are detected in the receive stream. If enabled, when the event occurs, bit 6 of the G1 byte (or the RAD output PRDI6 bit position) is set high while bit 7 of the G1 byte (or the RAD output PRDI7 bit position) is set low. 4.2 Do wn loa de db yV When TIUPERDI is set low, trace identifier (mode 1) unstable events have no effect on path RDI. In addition, this bit has no effect when PERDI_EN is set low. DOOL (data out of lock) declaration – page 111 Section 11.1.1 Clock Recovery Unit , should state that the PLL will revert to the reference clock if there are no data transitions after 96 bit periods. The clock recovery unit recovers the clock from the incoming bit serial data stream. The clock recovery unit is fully compliant with SONET/SDH jitter tolerance requirements. The clock recovery unit utilizes a low frequency reference clock to train and monitor its clock recovery PLL. Under loss of signal conditions, the clock recovery unit will continue to output a line rate clock that is locked to this reference for keep alive purposes.

When the frequency of the recovered clock is within 488 ppm of the reference clock, the PLL attempts to lock to the data. Once in data lock, the PLL reverts to the reference clock if no data transitions occur in 80 96 bit periods or if the recovered clock drifts beyond 488 ppm of the reference clock. ay ,1 The following highlighted text should be removed from section 11.8.3 Transmit Pointer Interpreter Processor (TPIP): hu rsd The TPIP is held in reset in DS3 mode, DS3ADDSEL = ‘1’ and when SLLBEN = '0' (reg 1n00).

The receive stream replaces the transmit STS-1 (STM0/AU3) or equivalent stream from the ADD bus. When SLLBEN is set low, system side line loopback of the corresponding receive stream is disabled, the data stream from the ADD bus is processed normally. The system side line loopback can only be enabled when the DS3 ADD Bus stream is disabled via the DS3ADDSEL register bit in the SPECTRA-622 TPPS Path and DS3 configuration register. SLLBEN has not effect when DS3ADDSEL is set high. When SLLBEN is low, TPIP is held in reset – TPIP registers cannot be accessed.
