Instruction manual

GLOSSARY
Interface
A common boundary between two systems or pieces of equipment.
Internal Call
A connection between two users within the system.
ISDN Gateway
An adjunct network that forwards information from the switch to a host for data screen
delivery to agents in an ACD split.
L
Link
A transmitter-receiver channel or system that connects two locations.
Loop-Start Trunk
After establishing a connection with the distant switching system for an outgoing call, the
system waits for a signal on the loop formed by the trunk leads before sending the digits
of the called number. On incoming calls, the received request for service is sufficient to
cause the call to route to a predetermined destination, normally the system attendant
group. No digits are received.
M
Main/Satellite/Tributary
A main switch provides interconnection, via tie trunks, with one or more subtending
switches, called satellites; all attendant positions for the main/satellite configuration, and
access to and from the public network. To a user outside the complex, a main/satellite
configuration appears as a single switch, with a single Listed Directory Number (LDN). A
tributary is a switch, connected to the main switch via tie trunks, but which has its own
attendant position(s) and its own LDN.
Message Center
An answering service for calls that might otherwise go unanswered; an agent accepts
and stores messages for later retrieval. (Requires an Applications Processor.)
Message Center Agent
A member of the Message Center Hunt Group who takes and retrieves messages for
voice terminal users.
