Busy Status Display
When a display multiline terminal user places an Intercom call to a busy extension,
the details of the busy status (who it talking to the extension or which line is in use by
the extension) can be displayed. The details of the trunk’s busy status (the extension
using the line) can be displayed after trying to access the trunk. This feature provides
a user information which can determine whether they should use the Barge-In feature
for the extension or trunk. This information automatically displays for a multiline
terminal once programmed.
Internal Hub
A network switch is a computer networking device that connects network segments. It
uses the logic of a network bridge but allows a physical and logical star topology. The
switch determines how and to which port the data is forwarded, based upon layer 2
MAC addresses. It is often used to replace network hubs. A switch is also often
referred to as an intelligent hub.
Switches, unlike hubs, use microsegmentation to create collision domains, one per
connected segment. This way, only the Ethernet devices which are directly connected
via a point-to-point link, or directly connected hubs are contending for the medium.
By eliminating the possibility of collisions, full-duplex point-to-point connections on the
switch become possible.
When multiple ETUs requiring Ethernet data connections are installed in an Electra
Elite IPK II KSU, the HUB ETU can provide a neat and simple installation.
The HUB(8)-U( ) ETU is an in-skin, fast Ethernet switching hub unit that provides the
following services:

Basic LAN Settings:

Port Mirroring
IP Station (MEGACO) – IAD (Integrated Access Device)
The IAD (8)-U( ) ETU with IP Station (MEGACO) application loaded is an optional
interface package for the Electra Elite IPK II system that converts digital station ports
into MEGACO IP station ports.
An on-board 10/100 Base-T connector provides a WAN/LAN connection. Voice and
signaling data from/to the IP stations are converted into IP packets and transmitted
through the Data Communication IP Network Intranet or Internet. The IAD (8)-U( )
ETU supports station to station direct RTP connections (peer-to-peer) for calls
between IP telephones. Each IAD (8)-U( ) ETU supports up to eight IP telephones.
