Internal Functional Blocks | Agilent Technologies HDMP-3001 manual

1. Introduction

The Agilent HDMP-3001 is a highly integrated VLSI device that provides mapping of Ethernet en- capsulated packets into STS-3c payloads. The HDMP-3001 sup- ports full-duplex processing of SONET/SDH data streams with full section, line, and path over- head processing. The device supports framing pattern, scrambling/descrambling, alarm signal insertion/detection, and bit interleaved parity (B1/B2/B3) processing. Serial interfaces for SONET/SDH TOH overhead bytes are also provided. The HDMP- 3001 provides a line side interface that operates at 155.52 Mb/s (8-bit bus at 19.44 MHz). For Ethernet applications a system interface operating at 25 MHz is provided. LAPS (Link Access Procedure – SDH) support includes framing, transparency processing, 32-bit FCS processing, and self- synchro- nous scrambling/descrambling (X43 +1). The HDMP-3001 also provides GFP (Generic Framing

Procedure) support which in- cludes framing, 32-bit FCS processing, 16-bit HEC process- ing, and self-synchronous scrambling/descrambling

(X43 +1).
