not only phone service but also voice mail, an automated attendant, automatic call distributor (ACD)
and computer integration.
The system itself is housed in a surprisingly small case that is wall-mounted in the telephone
equipment room. An external, wall-mounted power transformer powers the system.
Programming of the system can be done locally or remotely through either the phone or the

Esi-Access
program (on a PC-compatible computer which has either dialed into
the system from another location or is physically connected to its RS-232C serial port).
