Electra Elite IPK II Document Revision 1
IP Station (MEGACO) - IAD (Integrated Access Device) 2 - 465
IP Station (MEGACO) - IAD
(Integrated Access Device)
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 10/100 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.
The IAD ETU contains a regular TCP/RTP/IP stack that can handle real time media, supports industry
standard MEGACO (H.248) communication on the WAN side, and interfaces 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.
This interface can provide:
J
MEGACO (H.248) signaling Protocol
J
DTMF generation
J
RTP port number designation
J
ToS field QoS support
J
Tone generation
J
General Tone detection
J
G.711 and G.729a voice compression
J
10/100 Base-T LAN interface
J
Echo Canceller
J
Remote configuration and maintenance
J
NAT Beater - Network Address Translation
For this feature, the IAD (8)-U( ) ETU is installed and assigned as an ESI (8)-U( ) ETU. Each IAD(8)-U( )
ETU supports up to eight IP Phones and reduces the maximum capacity of stations in the system by
eight.
A maximum of 14 IAD (8)-U( ) ETUs can be installed supporting the maximum of 112 stations (refer to
Table 2-30 KSU Power-Based Calculator Chart on page 2-898 in the Universal Slots feature).
