1-Port OC-48/STM-16 POS SPA Overview
Note
The WRAP, PASSTHRU, and MATESYNC LEDs apply to the SPA in RPR/SRP mode only.
The 1-Port OC-48/STM-16 POS SPA LEDs are described in
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.
