FE1-V35

The data port is V.35, with the data rate optional from 64K to 2048K depending on the number of the selected time slots. M34 connector is adopted.

Line interface is E1, which supports framing structure and non-framing structure and provides optional balanced or unbalanced connection mode

FE1/V.35 Interface Converter is available with four optional clocks: 1) V35 interface timing (S5.1=OFF, S5.2=OFF), i.e., sending timing is set at V35 interface and the received data is synchronized via BUFF with V35 interface timing; 2) E1 interface receiving timing (S5.1=OFF, S5.2=ON), i.e., sending timing is E1 interface receiving timing and the received data is synchronized via BUFF with E1 interface receiving timing, under which local time slot setting can automatically track the opposite time slot setting; 3)E1 interface timing (S5.1=ON, S5.2=OFF), i.e., sending timing is E1 interface timing and the received data is synchronized via BUFF with E1 interface timing; 4)Main timing (S5.1=ON, S5.2=ON), i.e., sending timing is local crystal oscillation and the received data is synchronized via BUFF with local timing.

FE1/V.35 Interface Converter is available with V.54 diagnosis function, supports local analog /digital loopback and also remote loopback function and provides false random code detection function to accomplish an end-to-end integrity test, which enables the subscriber to carry out line test and fault diagnosis conveniently.
