All of the circuits to Elizabeth City are intertoll two-way dial circuits.

Windsor is a tributary office of Williamston, meaning the operators were in Williamston for the Windsor customers. These circuits would dial toward Windsor and just ring toward Williamston. Both of these offices were in CT&T territory so I don't know why these records are in my collection.

H carrier is one channel, operating on 7.5 KHz, USB one direction and LSB the other. (And you thought single-side-band was a modern thing.) It weighed more than 50 pounds per channel. OB carrier is the second frequency allocation of the O carrier family which consists of OA OB OC OD, also using single-side-band.

One pair of open-wire could carry the following:

• One physical voice circuit, signaling separate.
• Two signaling circuits, either dial or telegraph.
• One H carrier.
• One OA carrier, or more commonly three Lenkurt 33 carriers (same as WeCo C carrier).
• One OB, one OC and one OD.
• OC and OD didn't perform well with multiple systems on one wire route so usually only one of each would be provided per route.

An additional phantom circuit could be run over two pair of wires.
