Advisory August 5, 1999 TMPR28051 STS-1/AU-3 (STM-0) Mapper Device Advisory for Version 5 of the Device Register Architecture (RA) Map RA-1. Reset Bit The software reset bit (bit 0) of register 0x00 is not functional. RA-2. Transmit Path AIS Insert Bit The TXPAISINS bit (bit 5) of register 0x01 produces both AIS-P and AIS-L. RA-3. STS-1 Loss of Pointer Mask Bit The STS1LOPMSK bit (bit 2) of register 0x04 masks both STS1LOP and STS1LOF. RA-4. STS-1 Loss of Frame Mask Bit The STS1LOFMSK bit (bit 1) of register 0x04 is not functional. RA-5. VTLABCOM and VTRFIRDICOM Interrupt Bits Occasionally, it might require multiple reads to clear the composite interrupt bits VTLABCOM (bit 2 of register 0x05) and VTRFIRDICOM (bit 4 of register 0x05). Error Insertion (EI) EI-1.
