AN-FE1-V.24 framing structure interface converter adopting ASIC (application specific integrated circuit) design. It is capable of converting N*64K continuous data flow into PCM signal of E1, with a rate up to 128Kbps. Mode of V.24 interface of this converter is DCE, it connects DTE device through direct cable, and connects DCE device through cross cable.

• V.24 rate Nx64kbps(（N=1~2）optional arbitrarily
• Universal - Framed/Unframed modes supported
• Support local analog/digital loopback
• Support remote loopback function
• Provide pseudo-random code test function
• V.24 interface uses DB25 standard connector
• E1 interface supports framing and non-framing modes, with the occupied time slot selected arbitrarily
• E1 interface balanced 120Ω/unbalanced 75Ω optional
• AC 220V and DC –48V inputs may be selected for interface converters of both structures
• For rack-mounted interface converter, dual power supply heat backup is provided to ensure a high operating reliability.
