event message
These are messages generated by the system to record activity. The messages are written
to the system log.
external call
A call to or from a destination outside the Business Communications Manager system.
external line
A line assigned to a telephone that allows calls to the PSTN.
external paging
A feature that allows voice announcements over an externally-installed loudspeaker
connected to the Business Communications Manager. The external speaker is not an
Business Communications Manager component.
FAX
FAX works with Business Communications Manager Voice Messaging. FAX allows a
caller to send a fax document to a voice mailbox.
feature code
A unique code used to access Business Communications Manager features and options on
the telephones.
filtering
Filtering is the process of examining a data packet on the network to determine the
destination of the data and whether the packet gets passed along on the local LAN, copied
to another LAN, or dropped.
frame relay
A frame relay is a high-speed, packet switching WAN protocol designed to provide
efficient, high-speed frame or packet transmission with minimum delay. Frame relay uses
minimal error detection and relies on higher level protocols for error control.
gateway
A system that links two different types of networks and enables them to communicate with
each other. The Business Communications Manager can provide the gateway to an
intranet or internet.
ground start trunk
Ground start trunks provide the same features as loop start trunks. Use this type of trunk
when the local service provider does not support disconnect supervision for the digital
loop start trunks. By configuring lines as ground start, the system can identify when a
caller hangs up the telephone at the far end. Ground start trunks are available only on a
Digital Trunk Interface (DTI).
