1-Port Channelized STM-1/OC-3 SPA Interface Specifications

The framer processes incoming and outgoing SONET or SDH frames. The framer operates at
OC-3c/STM-1 line rates (155.52 Mbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP])
and is mapped into the STS-3c/STM-1 frame.
The 1-Port Channelized STM-1/OC-3 SPA interface is compliant with RFC 1619, PPP over
SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The 1-Port Channelized STM-1/OC-3 SPA
also provides support for SNMP v1 agent (RFC 1155–1157), and Management Information Base (MIB)
II (RFC 1213).
