Description  
- Ringing Voltage  
- Switch Hook  
The Mitel MH88634-2 Central Office Interface Circuit  
trunk provides a complete analogue and signalling  
link between audio switching equipment and a  
telephone Line. The device is available in a single in  
line package for high packing densities or with a lead  
frame formed at 90° for low clearance applications.  
One Relay Driver  
On-Hook Reception  
Small footprint area  
Meets FCC Part 68 Leakage Current  
Requirements  
The device is fabricated as a thick film hybrid  
incorporating various technologies for optimum  
circuit design and very high reliability.  
Applications  
Interface to Central Office for:  
PABX  
This part supercedes the MH88634-2 and is pin for pin  
compatible.  
Key Telephone Systems  
Channel Bank  
We advise that the B rev parts are fully tested.  
However, we do not expect to see changes between  
MH88634-2 and MH88634BV-2.  
Voice Mail  
Terminal Equipment  
Digital Loop Carrier  
Optical Multiplexer  
The component design has been changed to  
improve the general performance of the part. It is  
also now capable of operating at a 24V battery.
