Detailed Product Description
The ICT FE1/V.35 provides an effective way to establish a permanent data link over a G.703/G.704 line. It performs the conversion between V.35 (N?64Kbps (N<=32)) and framed E1, suitable for the connection between a DTE equipment with V.35 interface and a E1 link. It can also functions as an access unit of digital services and features the benefits of compact size, high operating stability, ease of operation and maintenance. Options of standalone or line card are available
FEATURES:
l Conversion between V.35 N x 64K (N<=32) and E1 (2048Kbps, framed and unframed)
l full duplex, supports local and remote loopbacks in compliance with V.54 standard
l E1 interface: framed or unframed selectable
l Line code:HDB3
l Supports both PCM30 and PCM31 mode
l Supports CRC function
l Support range up to 1.5KM over 0.5mm wire gauge
l clocking: internal, external, network(receive)
l front panel status LEDs
l Line impedance:120ohm balance / 75ohm unbalance selectable
l Built-in Bit Error Rate Tester (BERT) for complete testing of the local and remote unit
l Compact in size
l low power consumption: <=2.5W
l 220VAC or -48VDC power supply
