U-BUS/DNIC Input/Output Transformer
TEW5039
TEW5039 is designed to inter-
face with the subscribers prem-
ises (NT) and the 2- wire line
side of the Central Office Equip-
ment (LT) in the ISDN Network.
TEW5039 meets the electrical re-
quirements for the
Mitel MT8972 & MT8971B/72B
devices.
Certified to EN60950 and
EN41003.
Applications:
• Up to 50 mA line current.
• TEW5039 meets the
requirements of BS6301 for
reinforced insulation,
clearance and creepage
distances between the line
and the device side.
• TEW5039-1 meets the
requirements for pollution
