E1 to V.35 or V.24 Converter Description

The E1 to V.35 converter and E1 to V.24 converter use one E1/G.703 to convert to V.35. It can convert successive N*64K (N=1--32) data stream into PCM signal of E1. The data rate is up to 2048Kbps. Placed in E1 frame, data of user just need necessary timeslot. Setting timeslot is continuous and according with rate of data port. The data ports have V.35 and V.24/RS232C which are optional. The ports support external clock and become linking end line.


E1/FE1-V.24/ V.35 converters provide physical conversion between ITU-T G.703 standard E1 or Framed E1 interface and standard V.24/ V.35 interface and offer security and seamless link for communication between different devices with different interfaces. It can take out specified time-slots from G.703 E1 or FE1 to compose V.24/ V.35, the device to transfer data have V.24 or V.35 output. Data interface mode is DCE, can connect with DTE or DCE devices.


Technical specification:


E1 interface:

  1. Coding: HDB3.

  2. E1 Impedance: 75Ω (unbalance) and 120Ω (balance).

  3. Clock: three modes for option.

  4. Jitter tolerance: fine than G.742 and G.823.

  5. Frame structure: framing match G.704, support time-slot.


V.24 / V.35 interface:

  1. Interface Rate: n*64Kbps, n=1~2.

  2. Interface character: match V.24 or V.35.

  3. Connector: DB25 (female).

  4. Interface type: DCE.

  5. Clock: G.703 resume clock, internal clock.
