General Description

The VSC8151 is a 2.488Gb/s Section Termination device which both monitors and modifies the section and

line overhead of a received SONET/SDH signal, and can generate AIS-L maintenance signals for trouble sec-

tionalization. These features allow all section termination requirements to be supported for Operations, Admin-

istration, Management, and Provisioning (OAM&P) functions in SONET/SDH terminal and optical networking

applications. An integrated 2.488Gb/s serial transceiver isolates the SONET/SDH signal interface, allowing

protocol information to be exchanged with programmable logic using a low-speed TTL interface.

Functional Overview

The VSC8151 is divided into two logic sections, a monitoring section and a modification section, each

interfaced externally through both 2.5Gb/s serial interfaces as well as 16-bit parallel interfaces. Incoming

SONET/SDH data is demultiplexed, framed, descrambled, and the 27 bytes of the section and line overhead are

output. The BIP parity of the incoming signal is calculated and compared with the received B1 and B2 bytes for

calculating received parity errors. The byte aligned data, calculated B1/B2 parity, and frame boundary location
