cessing, administration, or maintenance capabilities. In addition to the Z3A Message Waiting
Indicator, DEFINITY Generic 1 and Generic 3 can support the following adjuncts:
EIA terminal such as the 4410 BCT (TTY 5410) and 4415 (TTY 5420)
Personal computers, such as the AT&T PC 6300, PC 7300, PC 6312, or 6386 Work-
Group System (WGS)
HORIZONï communications system, MERLINï communications system, and Informa-
tion Systems Network (local area network) switching systems
Two multiplexers, the Channel Expansion Multiplexer (which doubles the channel capa-
city of a DS1 facility to 44 voice band channels) and the Channel Division Multiplexer
(which provides non-switched private line connections over DS1 facilities)
Protocol converters to allow ASCII terminals and personal computers to communicate
with SNA/SDLC IBM computer and bisynchronous networks, thus protecting investments
in existing low-cost terminals as data networks grow or are integrated and as protocols
change
