1-Port Channelized OC-12/STM-4 SPA Interface Specifications

The framer processes incoming and outgoing SONET or SDH frames. The framer operates at
OC-12/STM-4 line rates (622.08 Mbps), and supports channelization from OC-12 down to DS0 line rates.
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP])
and is mapped into the STS-12/STM-4 frame.
The 1-Port Channelized OC-12/STM-4 SPA interface is compliant with RFC 1619, PPP over
SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The 1-Port Channelized OC-12/STM-4 SPA
also provides support for SNMP v1 agent (RFC 1155–1157), and Management Information Base (MIB)
II (RFC 1213).

1-Port Channelized OC-12/STM-4 SPA Cables and Connectors

The 1-Port Channelized OC-12/STM-4 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
