| Remember when the telephone industry had switchboards and operators? |
| The tactical network consisted of satellite terminals, telephone switchboards and data network operation equipment. |
| There was a shortage of switchboards, field wire, open wire, insulators, construction troops, and teletype machines. |
| Last year the traffic on international telephone switchboards topped 100 billion for the first time. |
| As manual switchboards were phased out after World War II, we started moving from analog to digital telephony. |
| By 1887 there were 26,000 telephones in use in Britain and multiple switchboards had been installed in most major towns and cities. |
