In [[hospital]]s, "switchboard" can also have duties in dealing with [[medical emergency]] (when announced on the telephone), [[disaster]]s and [[resuscitation]] calls.
In the early days of telephony, through roughly the 1960s, companies used manual [[telephone switchboard]]s and switchboard operators connected each call by inserting a pair of [[TRS connector|phone plug]]s into the appropriate jacks. Each pair of plugs was part of a [[cord circuit]] with a switch associated that let the operator participate in the call. Each jack had a light above it that lit when the telephone receiver was lifted (the earliest systems required a generator on the phone to be cranked by hand). Lines from the central office were usually arranged along the bottom row. Before the advent of [[direct distance dialing]], switchboard operators would work with their counterparts in the central office to complete [[long distance]] calls.
A note: in the United States of America, any switchboard operator employed by an independently owned public telephone company which has not more than seven hundred and fifty stations is excluded from the [[Equal Pay Act of 1963]].
