1-Port OC-12c/STM-4 POS SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at
OC-12c/STM-4 line rates (622.08 Mbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]),
and is mapped into the STS-12c/STM-4 frame.
The 1-Port OC-12c/STM-4 POS SPA interface is compliant with the following RFCs:
• RFC 1619, PPP over SONET/SDH
• RFC 1662, PPP in HDLC-like Framing
The 1-Port OC-12c/STM-4 POS SPA also provides support for SNMP v1 agent (RFC 1155–1157) and
RFC 1213:
• RFC 1155, Structure and Identification of Management Information for TCP/IP-based Internets
• RFC 1156, Management Information Base for Network Management of TCP/IP-Based Internets
• RFC 1157, Simple Network Management Protocol (SNMP)
