U-BUS/DNIC Input/Output Transformer
TEW5318
TEW5318 is designed to inter-
face with the subscriber prem-
ises (NT) and the 2-wire line
side of the central office equip-
ment (LT) in the ISDN system.
TEW5318 meets the require-
ments for the Mitel MT8972 and
MT8971B/72B devices.
Features:
• Low profile construction.
• Handles 100 mA unbal-
anced line current.
TEW5318-1 is supplied with a
“Flux-band” for additional cross
talk suppression.
