[GreenKeys] East Wire and West Wire?

[Commtekman at aol.com]

And I have seen it labelled North & South, as the open wire that I  worked 
on ran up and down a deep valley with 14,000' mountains on each side. The  
OW also had Lenkurt 33 cxr running on it with local & main lines with  
rolling and straight transposition at regular distances. Ring down or mag  
circuits were still common on outlying areas that didn't have any type of dial  
service, either by microwave drop or radio link.

In  telegraphy you often have a wire that loops through a station.
So one  direction from the station is arbitrarily called East and
the opposite  direction is called West.  I've also seen North and
South used in some  Western Union circuits and in railroad usage.

Also in telephone carrier  systems, where a different frequency
is used in each direction, a carrier  terminal will be identified
as East or West depending on which frequency is  used in which
direction.  Likewise in a two-wire system with repeaters  the
two ends of the repeater will be labelled East and West, although
in  this case it doesn't matter which end is which since it
repeats the same  frequencies in both directions.

Since the designations are arbitrary  you'll have circuts labelled
East and West even if the wire runs directly  north and south.  And
occasionally due to strange circuit geography  you'll find a circuit
labelled East that actually leaves the west side of  the office before
going toward the  East.
