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 (155.52 Mbps) line rates. 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 OC-3c/STM-1 POS SPA interface is compliant with RFC 1619, PPP over SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The OC-3c/STM-1 POS SPA also provides support for SNMP agent v1 (RFC 1155-1157), and Management Information Base (MIB) II (RFC 1213). OC-3c/STM-1 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. 3-22 Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide OL-5052-14

2-Port and 4-Port OC-3c/STM-1 POS SPA Overview
The 2-Port and 4-Port OC-3c/STM-1 POS SPA LEDs are described in
Table 3-12
.
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 (155.52 Mbps) line rates.
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 OC-3c/STM-1 POS SPA interface is compliant with RFC 1619,
PPP over SONET/SDH
, and RFC
1662,
PPP in HDLC-like Framing
. The OC-3c/STM-1 POS SPA also provides support for SNMP agent
v1 (RFC 1155-1157), and Management Information Base (MIB) II (RFC 1213).
OC-3c/STM-1 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.
