Two types of Attendant consoles are available with the SX-ZOO DIGITAL PABX. The
LCD Console uses four wires and interfaces with the Console module on the
Universal Card. The SURERC0A/S0~E 1000m Attendant Console uses one pair of
\
wires and interfaces to a Digital Line Card; it also has an RS-232 printer port and a
