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).
Handsfree
A feature used to make calls without using the telephone receiver. Activate Full Handsfree
under Capabilities in System DNs programming. When activated, the Business
Communications Manager assigns a Handsfree/Mute button to the telephone.
