- How many lines you want to run may also determine your approach. We are
- running 16 phone lines into a bank providing deposit information. The
- overhead of sending out digitized voice data for that many lines threatened
- to swamp the application processing going on. Ergo, we implemented a
- PC which caught all the line traffic, then multiplexed it down to a single
- line into the unix server, which then split it out to application
- transactions. The conversion between the unix system and the PC was
- simple:
- PC Unix
-
- 2#
- 3
-
- 1#
- $13432.45
-
- And the PeeCee took care of retrieving the voice data, synthesizing the
- messages ("thirteen thousand, four hundred and thirty two dollars and ...")
- and spitting out the result. If I remember right, some of those prompts
- took 40k to store away. I wouldn't want to shoot that data down a serial
- line.

- The hardware we used was built by Rhetorix.
