SEMICONDUCTOR TECHNICAL DATA  
(UDLT II)  
The MC145421 and MC145425 UDLTs are high–speed data transceivers  
capable of providing 160 kbps full–duplex data communication over 26 AWG  
and larger twisted–pair cable up to 1 km in length. These devices are primarily  
used in digital subscriber voice and data telephone systems. In addition, the  
devices meet and exceed the CCITT recommendations for data transfer rates  
of ISDNs on a single twisted pair. The devices utilize a 512 kbaud MDPSK burst  
modulation technique to supply the 160 kbps full–duplex data transfer rates.  
The 160 kbps rate is provided through four channels. There are two B channels,  
which are 64 kbps each. In addition, there are two D channels which are  
16 kbps each.

The MC145421 and MC145425 UDLTs are designed for upward compatibility  
with the existing MC145422 and MC145426 80 kbps UDLTs, as well as compa–  
tibility with existing and evolving telephone switching hardware and software  
architectures.
