Optiset E Teleworking Adapter
The Optiset E Teleworking Adapter (OTA) is a component of
the Teleworking Application that enables an Optiset E display
telephone to be used by a remote teleworker or telecommuter.
Once the option module is installed, the Optiset E telephone
will work with all of the Hicom 300 E CS features available to
the telephone when connected directly to the communications
server.
With the OTA, a teleworker can replicate the configuration of
his or her office with regard to the PC and telephone equipment.
The OTA option requires a PC running the OTA Service
Sofware, a local power supply, and any one of the Optiset E
display phones. The adapter is a standard bay option module
that can be installed underneath the base of the phone, however,
it can operate without being plugged into a telephone.
Note: Refer to the Teleworking Client Installation and Guide
(G281-0518-00) for more information regarding this
application.
Only the Optiset E Standard, Advance, Advance Plus,
and Advance Conference telephones support this
option.
