Design IP - SONET / SDH

SONET / SDH has become the worldwide standard for the interface and multiplexing of user information through optical networks. SONET / SDH systems allow much greater network flexibility and management over existing optical systems. Kacper provides framing, pointer processing and overhead processing solutions.

Features:

   » Complaint with SONET ANSI T1.105, GR-253-CORE and ITU-T G.707.

   » The framer supports standard Sonet mappings down to OC-48 channels and can be used as either a single OC-48       framer or four individual OC - 12 framers.

   » Provides access to internal registers through a Control Interface.

   » Performs Byte and Frame alignment on the Receive signal.

   » Pointer Processors at STS / STM and VT / TU levels.

   » Generates Frame Co-ordinates (N, row, column) for path processing. Accepts external synchronization pulse for the       transmit start of frame.

   » Inserts the Framing Bytes (A1, A2) and Section Trace J0 Byte or STS-1 ID (C1).

   » Optionally inserts the section & line data communication channels (D1-D3) or (D4–D12)

   » Optionally inserts register programmable APS Byte failure (K1, K2) and synchronization status S1 Bytes.

   » Computes and inserts section BIP-8 (B1), line BIP-8 (B2), path BIP-8 (B3) and Path Far End Block Error FEBE (G1).

   » Optionally scrambles the Transmit Frame data and optionally descrambles the receive frame data.

   » Remote defect, error and failure indications(AIS-L, AIS-P, AIS-V, MS-AIS, AU-AIS, TU-AIS).

   » Pass through of TOH bytes.

   » Supports 16-bit asynchronous and synchronous microprocessor interface up to OC-48.

   » Fully synthesizable Register Transfer Level (RTL) Verilog / VHDL Core.
