Description  
The Mitel MH88437 Data Access Arrangement  
(D.A.A.) provides a complete interface between  
audio or data transmission equipment and  
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.  
Meets French current limit requirements  
Conforms to German dial pulse standards  
Approvable to UL 1950  
a
Industrial Temperature Range Available  
Applications  
Interface to Central Office or PABX line for:  
FAX/Modem  
The impedance and network balance are externally  
programmable, as are the DC termination  
characteristics, making the device suitable for most  
countries worldwide.
