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