We use our single ECS line for a variety of functions ... different hardware 
& software consultants dial in using different protocols & we found it 
expedient to give each one a separate configuration all of which own the same 
comm line but only one can have it at a time, so we vary off folks, with 
default being varied on for IBM, then when we need to use the line for other 
folks & functions, vary off IBM & vary on whoever.  This is a bit of a trip 
since none of them have consistent protocols, some need master security 
clearance to vary on off their connection.  Some day I will put the whole bit 
on a menu using adopted authority ... take this menu option to vary off 
whoever has the line & transfer it to whoever.

We no longer do EDI, but when we did, they needed different modem deal than 
the one we were using for ECS, so we ended up with A/B switches from Black 

The wiring was ma bell plug with phone line to "C" connection of A/B phone 
line switch, with "A" going to one modem & "B" going to other modem, then the 
AS/400 comm lines from modems going to corresponding A & B connections of 
comm line A/B switch, then "C" line into AS/400 itself.

So the switcheroo involved:
vary off whoever now owns "B" line, manually switch both A/B switches from B 
to A, vary on whoever now owns "A" line.
At one time company wanted EDI to run automatcially off of job scheduler at 
particular time of day to get stuff based on expected schedule of customer 
delivering to mail boxes & also wanted customer service people to be able to 
run EDI on demand from some menu when they heard from some contact that there 
was stuff out there for us, but we had so much hassle with ma bell phone 
lines bad connections with EDI VANs & end users not being able to cope with 
the scenarios that the job reverted to MIS just get us the data & if it bombs 
due to lousy ma bell just deal with it & get us the data.
