TEW-5291 Series Bridging Transformer

TEW-5291 is designed to be used as a high impedance “Bridging Transformer” in the ISDN primary rate access network for T1 and CEPT applications. TEW-5291 will not significantly affect the line impedance, hence the return loss, if loaded with a high impedance >10 Kohm. Connect pin 1 & 8 across the line, short pin 4 to pin 6 and terminate 3 & 5 with a high impedance, not lower than 10Kohm.

  • Primary rate ISDN network nodes.
  • PBX or computer to T1/CEPT Digital trunks.
  • High speed data link using T1/CEPT Digital Trunk.
