Description  
The MT9079 is a feature rich E1 (PCM 30, 2.048  
Mbps) link framer and controller that meets the latest  
CCITT and ETSI requirements.  
Automatic interworking between CRC-4 and  
non-CRC-4 multiframing  
Dual transmit and receive 16 byte circular  
channel buffers  
Two frame receive elastic buffer with controlled  
slip direction indication and 26 channel  
hysteresis (208 UI wander tolerance)  
CRC-4 updating algorithm for intermediate path  
points of a message-based data link application  
The MT9079 will interface to a 2.048 Mbps  
backplane and can be controlled directly by a parallel  
processor, serial controller or through the ST-BUS.  
Extensive alarm transmission and reporting, as well  
as exhaustive performance monitoring and error  
diagnostic features make this device ideal for a wide  
variety of applications.  
Applications
