Input/Output Transformer
The 4 wire interface between Sub-
scriber Terminals and the Network
Termination has been stand-
ardized by CCITT recommenda-
tion I.430. It uses a passive bus
which provides separate receiver
and transmit loops operating at
192 Kbits/s.
Two versions of TEW6197 have
been designed and approved for
use with the following devices:
