Features
General Description
Administration, Maintenance, and Provisioning (OAM&P) at multiple SONET/SDH rates. Differential PECL
clock and data input receivers and a differential data output isolate the high-speed interface. Low-speed TTL
inputs and outputs allow the use of inexpensive programmable logic to perform OAM&P functions. The
VSC8150 is an ideal solution for constructing a non-intrusive SONET/SDH monitoring interface when visibil-
ity of payload data is not required.
Functional Description
CLKIN
framing alarms generated. Incoming B1 parity is calculated and compared with the transmitted B1 value, and
detected errors are output. The 27 bytes of the first STS-1 transport overhead are descrambled and output for
processing.
