Description
The Mitel MH88435 Data Access Arrangement
(D.A.A.) provides a complete interface between
audio or data transmission equipment and a
telephone line. All functions are integrated into a
single thick film hybrid module which provides high
voltage isolation, very high reliability and optimum
circuit design, needing a minimum of external
components.
The impedance and network balance are externally
programmable,
as
are
characteristics, making the device suitable for most
countries worldwide.
