GP-FE1V is a FE1/V. 35 framing structure interface converter adopting ASIC (application specific integrated circuit) design. It is capable of converting Nx64K continuous data flow PCM signal of E1, with a rate up to 1984Kbps (time slot 0 is used to transmit synchronizing information). Feature: 1. Supplies V. 54 diagnosis function 2. V. 35 rate Nx64kbps optional arbitrarily 3. Supports four clock modes 4. Supports local analog/ digital loopback 5. Supports remote loopback function 6. Provides pseudo-random code test function 7. V. 35 interface uses M34 standard connector 8. Supports framing and non-framing modes, with the occupied time slot selected arbitrarily 9. Balanced 120/ unbalanced 75Ω optional 10. Available with independent structure and 19-inch rack-mounted structure (rack-mounted structure can be ed with 16 modules) 11. AC 220V and DC 48V inputs may be selected for interface converters of both structures 12. For rack-mounted interface converter, dual power supply heat backup is provided to ensure a high operating reliability
