1-Port OC-192/STM-64 POS SPA Overview
The 1-Port OC-192/STM-64 POS/RPR SPA LEDs are described in Table 2-30.
1-Port OC-192/STM-64 POS/RPR SPA Interface Specifications
The 1-Port OC-192/STM-64 POS/RPR SPA contains a SONET/SDH framer to process incoming and
outgoing SONET or SDH frames. The framer operates at OC-192/STM-64 line rates (9.95 Gbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP])
and is mapped into the STS-192/STM-64 frame.
The 1-Port OC-192/STM-64 POS/RPR SPA interface is compliant with the following RFCs:
• RFC 1619, PPP over SONET/SDH
• RFC 1662, PPP in HDLC-like Framing
• RFC 2615, PPP over SONET/SDH
The 1-Port OC-192/STM-64 POS/RPR 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)
