 WE 543 DBMW - without Bell System markings. 8-78. NOS in box. |
| Western Electric 543 -- 4-button,
single
line, specific to a 761A PBX, designed for the small hotel/motel
market,
used in the guest rooms. (I don't ever remember staying in
a
hotel that used them!) Control buttons, exclusion key and "A-leads" (control leads) tell the switching equipment what kind of line to connect to the set (switching done within the PBX). Buttons marked: "Message waiting" (the front desk could illuminate it to alert you to a message), "Desk" (connected you to the front desk), "Local" (connected you to a CO trunk for a local call), and "Long distance" (gave you a direct path to a toll operator). The last three buttons are momentary contact. These button features relieved the attendant of having to route much of the guest traffic. Outwardly, these sets look like a 544 or 545 set but have fewer line cord conductors (12). 543DB – 641A line key, C4B ringer 543DBC – 588B line key, C4A ringer – field/distributor converted from 544BB or 545BB. |
