The Router 1-Port OC3 POS FIC uses the protocols such as PPP, Frame Relay and
HDLC at the data link layer and IP at the network layer. It allows direct transmission of
packets over SONET/SDH. It supports:
z Four types of SFP: multi-mode short-haul (1310 nm), single mode medium-haul
(1310 nm), single mode long-haul (1310 nm), and single-mode ultra-long haul
(1550 nm).
z 155.52 Mbps fractional interface
