1-Port OC-12c/STM-4 POS SPA Overview Chapter 3 Overview: Cisco 7600 Series Router Shared Port Adapters Table 3-14 1-Port OC-12c/STM-4 POS SPA LEDs (continued) LED Label STATUS Color Off Green Amber State Off On On Meaning SPA power is off. SPA is ready and operational. SPA power is on and good; SPA is being configured. 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) • RFC 1213, Management Information Base (MIB) for Network Management of TCP/IP-Based Internets:MIB II. 1-Port OC-12c/STM-4 POS SPA SFP Optical Transceiver Modules and Cables The POS SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber connection (see Figure 3-23). Cisco Systems qualifies the optics that are approved for use with its SPAs. The 1-Port OC-12c/STM-4 POS SPA supports the following types of optical transceiver modules: • Multimode (MM) SFP module-SFP-OC12-MM • Short reach (SR) SFP module-SFP-OC12-SR • Intermediate reach (IR) SFP module (15 km)-SFP-OC12-IR1 • Long reach (LR) SFP module (40 km)-SFP-OC12-LR1 • LR SFP module (80 km)-SFP-OC12-LR2 3-28 Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide OL-5052-14
