2-Port, 4-Port, and 8-Port OC-3c/STM-1 POS SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs Table 3-22 describes the 2-Port and 4-Port OC-3c/STM-1 POS SPA LEDs. Table 3-22 2-Port and 4-Port OC-3c/STM-1 POS SPA LEDs LED Label C/A A/L STATUS Color Off Green Amber Off Green Amber Off Green Amber State Off On On Off On On Off On On Meaning SONET controller is shut down. Port is enabled by software, and there is a valid SONET signal without any alarms. Port is enabled by software, and there is at least one alarm. Interface is shut down. Port is enabled by software, and loopback is off. Port is enabled by software, and loopback is on. SPA power is off. SPA is ready and operational. SPA power is on and good, and the SPA is being configured. 2-Port and 4-Port OC-3c/STM-1 POS SPA Interface Specifications The framer processes incoming and outgoing SONET or SDH frames. 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 2-Port and 4-Port OC-3c/STM-1 POS SPA interface complies with the following RFCs: • RFC 1662, PPP in HDLC-like Framing • RFC 2427, Multiprotocol Interconnect over Frame Relay • RFC 2615, PPP over SONET/SDH 2-Port and 4-Port OC-3c/STM-1 POS SPA Optical Transceiver Modules and Cables The 2-Port and 4-Port OC-3c/STM-1 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 qualifies the optics that are approved for use with its SPAs. The 2-Port and 4-Port OC-3c/STM-1 POS SPA supports the following types of optical transceiver modules: • Multimode (MM) SFP module-SFP-OC3-MM • Short-reach (SR) SFP module-SFP-OC3-SR • Intermediate-reach (IR) SFP module (15 km)-SFP-OC3-IR1 • Long-reach (LR) SFP module (40 km)-SFP-OC3-LR1 • Long-reach (LR) SFP module (80 km)-SFP-OC3-LR2 3-36 Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide OL-14126-12
