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 AIS-L, REI-L and RDI-L according to
receiver state with option of SW/HW insertion
Inserts LOS and forces SEF by software
Generates RDI-P and REI-P automatically with
optional SW/HW override
Inserts fixed-stuff columns, calculates and inserts
B3 error code
SONET RECEIVER
Performs standard STS-12/STM-4 receive process-
ing
Provides fully programmable threshold detection for
SD and SF condition
Provides section trace buffer with mismatch detec-
tion 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
Detects Out of Frame (OOF), Loss of Frame(LOF),
Loss of Signal(LOS) AND APS failure
Detects Line Alarm Indication (L-AIS), Line Remote
Defect Indication (L-RDI) and Loss of Pointer
Detects Path Alarm Indication, Path Remote Defect
Indication and Path extended RDI
Provides Signal Label Monitor with PLM detection
Supports path trace buffer with TIM-P and invalid
message detection
Computes and compare B3, REI-L and REI-P
errors
Computes and compare BIP-8 (B1,B2) and counts
the errors
MAPPER
Performs standard SONET STS-1 mapping for DS3
conforming with Bellcore GR-253 and GR-499
Performs SDH VC-3 mapping for DS3 and E3 to
conform ITU-T G.707
Implements AU-3 to VC-3 multiplexing and de-mul-
tiplexing
Provides STS-1 mapping and de-mapping func-
tions
Accepts data from external STS-1 inputs
In the transmit direction, provides STS-1 framing,
descrambling, performance monitoring and pointer
processing functions
In the receive direction, provides frame generation
and scrambling
SONET/SDH INTERFACE
Supports an 8-bit parallel interface at 77.76 MHz for
STS-12/STM-4 in Telecom bus format.
Supports an 8-bit parallel interface at 19.44 MHz for
STS-3/STM-1 in Telecom bus format.
Serial Interface at 622.08 MHz with SERDES
APS SUPPORT
Supports both 1+1 and 1:1 configurations
APS interface consists of two Serial Interface with
SERDES.
Provides both input and output interface for APS
E3/DS3/STS-1 INTERFACE
Supports up to 12 E3/DS3/STS-1 tributaries
In the receive direction, generates the single-rail or
dual-rail data along with smoothed E3/DS3 clock as
well as start of frame indication
Provides RX serial and single-rail (NRZ) data and
clock at 51.84 MHz for STS-1E
In transmit direction, accepts clear channel E3/DS3
signal and performs framing on incoming signal
DS3 RECEIVE FRAMER
Offers off-line framing algorithm
Complies with the standards as: Bellcore TR-NWT-
000499 and TR-NWT-000009
Supports overhead extraction
Provides line code violation detection and excess
zero count
Reports and counts FEBE
