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.
To 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).
