1-Port OC-48/STM-16 POS SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at
OC-48/STM-64 line rates (9.95 Gbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP])
and is mapped into the STS-48/STM-64 frame.
The 1-Port OC-48/STM-16 POS SPA interface is compliant with the following RFCs:
