and the other end into the BSV interface of the SIC-1BSV/SIC-2BSV interface card.

■If the line is an ISDN S/T interface line, directly connect the cable to the BSV interface of the SIC-1BSV/SIC-2BSV interface card.

2To connect the interface card to a TE device, use a crossover S/T interface cable. Connect the RJ-45 plug at one end of the cable to the BSV interface, the RJ-45 receptacle to a straight-through S/T interface cable, and then the straight-through cable to the TE device.

SIC-1FEF

Introduction SIC-1FEF is short for 1-port 100 Mbps fiber Ethernet interface card, where FE is short for Fast Ethernet and F for fiber, indicating an optical fiber interface. SIC-1FEF is used for the communication between the router and LAN.

SIC-1FEF supports:

■Five types of SFP removable optical interface modules: multimode short-haul (850 nm), single-mode medium-haul (1310 nm), single-mode long-haul (1310 nm), single-mode long-haul (1550 nm), and single-mode ultra-long haul (1550 nm).

■1000 Mbps interface rate

■Full duplex
