TFS 2574 is specifically designed for use as a Line Input Transformer in T1/CEPT applications. It has been approved by MITEL for use with their MH89760 and MH89790 devices. TFS2574 is available in five versions: - 0, -2, -3, -4 and -5 for 100, 120 and 75/120Ω line impedances. Also suitable as Input/Ouput transformer for other makes of T1/CEPT interface devices.
Typical applications are:
PBX or computer to T1/CEPT Digital Trunks. High speed data link using T1/CEPT Digital Trunk. TDM Multiplexers. ISDN Primary Rate.
