Generates and Transmits Standard STS-12/STM-4 data
Generates and Transmits either an STM-4/TUG-3 or STM-4/AU-3 signals for SDH applications
Conforms to ITU-T 1.432, ANSI T1.105 and Bellcore GR-253 Standards
Performs SONET frame insertion and accepts external frame synchronization
Performs Optional Transmit Data Scrambling
Permits the user to externally insert their own values for the POH and TOH into the outbound STS-12/STM-4
traffic
Generates transmit payload pointer (H1,H2) (fixed at 522) with NDF insertion
Inserts A1/A2 with optional error mask
Computes and inserts BIP-8 (B1,B2) with optional error mask
Generates and transmits REI-L and RDI-L either upon Software Command or automatically based upon
errors and defects that are detected/declared by the SONET Receiver.
Permits the user to transmit the LOS pattern via Software Command.
Generates and transmits RDI-P and REI-P either upon Software Command or automatically based upon
errors and defects that are detected/declared by the SONET Receiver.
3 or STS-3c SPE/VC-4
Receives and processes standard STS-12/STM-4 signals
Receives and processes either an STM-4/TUG-3 or STM-4/AU-3 signal for SDH Applications
Permits the user to fully program the B2 Byte Error-rate thresholds for declaration and clearance of the SD
and SF defect conditions
Provides section trace buffer with mismatch detection and invalid message detection
Performs SONET Frame Synchronization
Supports NDF, positive stuff and negative stuff for pointer processor
Performs receive data de-scrambling
Performs POH and TOH interpretation/extraction
Interprets payload pointer (H1,H2)
Extracts data communication channels from D1-D3 and D4-D12
Declares and Clears the SEF (Severely Erred Frame), LOF (Loss of Frame) and LOS (Loss of Signal) defect
conditions
Declares and clears the Line AIS (AIS-L) and the Line Remote Defect Indicator (RDI-L) defect conditions
Declares and Clears the Path - AIS (AIS-P), Loss of Pointer (LOP-P) and Path - Unequipped (UNEQ-P)
defect conditions.
Supports either the Single-Bit or Extended form of RDI-P
Monitors the Path Signal Label and declares/clears the PLM-P defect condition
Inserts the fixed-stuff columns, calculates and inserts the B3 byte value into each outbound STS-1 SPE/VC-
