Standard ....................................................
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 ver-
sions: - 0, -2, -3, -4 and -5 for 100,
120 and 75/120Ω line impedances.
Also suitable as Input/Ouput trans-
former 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.
