- University of Utah bought a SLC system to expand their modem bank,
- unfortunately they failed to check on wether it would support 28k, and
- are now in mess with US West over what to do with this piece of
- equipment.
- My first job was at Bell Labs, where we looked at using voice SLC for
- a single data chanel above the voice band on every suscriber loop.
- To get 28k on most suscriber loops on a SLC channel. would have taken
- a hell of a lot of line conditioning. In short, unless you pay for a
- conditioned line, you have no gurantee of getting a loop that supports
- 28k whether on a SLC interface or baseband. Most SLC's are not
- designed to carry 28k data, nor are suscriber loops guranteed to carry
-
- that type of modulation.
