Anybody interested in one or more AT&T 353A adapters ?
Here is a quote from the manual :
"The 353-type adapters are coaxial-to-twisted-pair baluns that eliminate the
need for coaxial cable to connect IBM 3170- and 3270-type data equipment
using the Type A protocol. The adapters balance the unbalanced coaxial
signals from the IBM equipment so that they are compatible with the
unshielded, twisted-pair wiring of the AT&T Premises Distribution System
(PDS). By using the 353 adapters at the terminal and controller, you can
maintain a data transmission link at a speed of 2,36 Mbps while saving the
expense of coaxial cable."
If anybody wants more information please let me know.
Stefan.
