E1 to V35 converter

  E1-V.35 converter provide conversion between ITU-T G.703 standard E1 interface and standard V.35 interface, can convert E1 channel of SDH, PDH, and other Optical Transmission Equipment or microwave, satellite Equipment to V.35 channel, Extend V.35 channel of DDN


E1-V.35 Interface Converter is a E1-V.35 framing structure interface converter adopting ASIC (application specific integrated circuit) design. It is capable of converting Nx64K continuous data flow into PCM signal of E1, with a rate up to 2048Kbps (time slot 0 is used to transmit synchronizing information).

Subscriber data is put within E1 frame, occupying only the needed time slot. Time slot is distributed freely according to the demand of the subscriber. When subscriber data rate is up to 2048Kbps, line transmission is of full transparent mode, i.e., non-framing structure.

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.

V.35 rate Nx64kbps((N=1~32)optional arbitrarily
Support four clock modes ( Internal clock, external E1 clock, sending E1 clock, V.35 clock)
Support local analog/digital loopback
Support remote loopback function
Provide false random code test function
V.35 interface uses M34 standard connector
E1 interface supports framing and non-framing modes, with the occupied time slot selected arbitrarily
E1 interface balanced 120ohm/unbalanced 75ohm automatic
Available with independent structure and 19-inch rack-mounted structure (rack-mounted structure can be inserted with 16 modules)
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
