1-Port OC-192/STM-64 POS SPA Overview

The 1-Port OC-192/STM-64 POS/RPR SPA LEDs are described in

Table 2-31

.

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)
