2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA Interface
Specifications
The framer processes incoming and outgoing SONET 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 Layer 2 frame.
The 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA interface complies with the following
IETF RFCs:
• RFC 1662, PPP in HDLC-like Framing
• RFC 2427, Multiprotocol Interconnect over Frame Relay Encapsulation
• RFC 2615, PPP over SONET/SDH
