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.
