3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
Receive STS-3 Transport Status Register – Byte 0 (Address = 0x1107)
• It will generate the “Change of LOS Defect Condition” Interrupt, by toggling the “INT*” output pin “LOW”,
and by setting Bit 0 (Change of LOS Defect Condition Interrupt Status), within the “Receive STS-3 Transport
Interrupt Status Register – Byte 0” to “1”, as illustrated below.
Receive STS-3 Transport Interrupt Status Register – Byte 0 (Address = 0x110B)
2.3.1.2.2
The Receive STS-3 TOH Processor block will clear the LOS defect once both of the following conditions have
been met.
That the Receive STS-3 TOH Processor block detects proper A1 and A2 bytes in two consecutive STS-3
frames, and
That, in between the detection of the two sets of A1/A2 bytes, the Receive STS-3 TOH Processor block does
not detect the “LOS_THRESHOLD[15:0]” number of “All Zero” bytes, within the incoming STS-3 data-stream.
Once the Receive STS-3 TOH Processor block clears the LOS defect, it will notify the system of this fact by
doing the following.
• It will set Bit 1 (LOS Detected) within the Receive STS-3c Transport Status Register – Byte 0” to “0” as
illustrated below.
Receive STS-3 Transport Status Register – Byte 0 (Address = 0x1107)
• It will generate the “Change of LOS Defect Condition” Interrupt by toggling the “INT*” output pin “LOW”, and
by setting Bit 0 (Change of LOS Defect Condition Interrupt Status), within the “Receive STS-3 Transport
Interrupt Status Register – Byte 0” to “1”, as illustrated below.
