INSTALLATION
NOTE: The telephone system referred to in
this manual is the customer premise
equipment such as an electronic key system,
a PBX or a dedicated single line telephone
sets. The VIP-821A is not intended for direct
or indirect connection to the public telephone
network. When used with a customer premise
telephone system such as a key system or
PBX system, these units are interfaced to the
FXS or single line station port, which is a fully
protected interface device. Also, the host
system must be configured to disallow central
office trunk conferencing in order to prevent
indirect connection to the public network.
