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.
