Electra Elite IPK II
IP Station (MEGACO) – IAD
Enhancements
This feature was added with Version 1100.
Version 1500 or higher allows IP stations, which have call forwarding set, to continue forwarding calls, even if
the station loses power or LAN connection.
Description
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 Base-T/100 Base-TX 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.
The IAD ETU contains a regular TCP/RTP/IP stack that can handle real time media, support industry
standard MEGACO (H.248) communication on the WAN side, and interface with the Electra Elite IPK as
a regular Electronic Station Interface board [ESI(8)-U( ) ETU].
From the network administration perspective, the IAD ETU is an end point on the IP network.
