Funny Coincidence

[Chip Fetrow]

In general, in old school telephone engineering a T-1 would spin out  
to 23 or 24 POTS lines, or 23 or 24 ISDN channels (or 12 2BSD).  Of  
course, today, with compression it can be pretty much as many as you  
want as long as you are willing to put up with the bad audio quality.

Broadcast Audio Loops were also equally dedicated over several T-1  
Channels.  An 8 k Hz loop would occupy three channels, as an example.


I never got the guys name.  He didn't offer, and I didn't ask.  I  
should have, as it turns out that today the problem is STILL not fixed.

I could not care less that the equipment is damaged.  I care that I  
don't know what is going on inside the electrical box and if there is  
a fault, there could be 240 Volts AC on the cabinet.

I should have asked for his card.
