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). 3-12 Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide OL-5052-14
