Chapter 1 Electra Elite IPK IAD(8)-U( ) ETU
SECTION 1DESCRIPTION
The IAD (8)-U( ) ETU with Megaco Station Package is an optional interface package
forElectra Elite IPKKTS that can convert digital station portsinto Megaco IP stations.
This ETU can be assigned as a ESI (8)-U( ) ETU and can support up to eight IP
Telephones.
The onboard 10/100 base T connector provides WAN/LAN connectivity. The
IAD (8)-U( ) 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 interface board. The IAD card,
from the network administration perspective, is an end-point on the IP network. For
the Electra Elite IPK system technician, it is just like any other Electronic Station
Interface.
This interface card can provide:
K Megaco (H.248) signaling Protocol
K DTMF generation
K RTP port number designation
K TOS field QOS support
K G.711 and G.729a voice compression
K 10/100 BASE-T LAN interface
K Echo Canceller
K Remote configuration and maintenance
K NAT - Network Address Translation Firewall
Refer to the Appendix E Electra Elite IPK IAD(8)-U( ) ETU Installation for instructions
for installing Echo Tuning in the IAD (8)-U( ) ETU hardware.

2.1 LED Indicators
A total of nine LEDs on this ETU are described in Table 1-1 Default Boot
Sequence: In Active IAD(8)-U10 ETU - Without IP Application Loaded.
2.1.1 Status LED
This LED chart shows the status of the IAD(8)-U( ) ETU during boot
up. The conditions change as the IAD(8)-U( ) ETU boots up and
passes through different boot states. This boot sequence will occur
with the IAD(8)-U10 ETU, when there is no IP Application loaded and
the card is at default.

The boot sequence shown below will occur on the IAD(8)-U10 ETU
when an IP Application has been loaded.
2.1.2 Hot Swap
The IAD(8)-U( ) does not require powering down the ETU or KSU.
The user can remove the IAD8)-U( ) ETU from the Electra Elite IPK
KSU the same way any other ETU is removed.
2.1.3 Ethernet Status
There are two built-in LEDs on the front of each RJ-45 connector to
indicate Ethernet connection status. These LEDs indicate data
transmission and reception (Transmit and Receive LED).

Chapter 2 IPK IAD(8)-U( ) ETU Setup
SECTION 1INSTALLING THE IAD(8)-U( ) ETU
1.1 System Requirements
The IAD(8)-U( ) ETU can be viewed and installed like any other ETU used in
the KTS system. (Refer to Appendix E Electra Elite IPK IAD(8)-U( ) ETU
Installation.) However, the CAT5 Ethernet cable plugs into the Ethernet
connector on the front of the ETU, and not through the regular connections as
with other interface boards.
1. Set the IAD(8)-U( ) ETU to desired card type in accordance with the dip
switch settings. (Refer to Table 1-3 IAD(8)-U( ) ETU Switches on page
1-4.)
2. Place the IAD(8)-U( ) ETU in the Electra Elite IPK KSU.
3. Connect the Ethernet cable to the J6 connector.
4. The CH1~CH8 LEDs start to run indicating that the system is initializing
the IP networking parameters. The status LED is red. (Refer to Table
1-1 Default Boot Sequence: In Active IAD(8)-U10 ETU - Without IP
Application Loaded on page 1-2.)
5. Once all LEDs are off and the status LED (D12) is flashing red, the IAD
(8)-U( ) ETU can be set up with the system.
1.2 Installation Precautions
As with all static sensitive devices, the ETU must be installed following the
Electra Elite IPK hardware installation general directions.

Chapter 3 IPK IAD(8)-U( ) Programming
SECTION 1SYSTEM PROGRAMMING
The IAD (8)-U( ) ETU (Megaco Station) is recognized by the Electra Elite IPK system
as an ESI(8)-U( ) ETU. This ETU takes longer to initialize than the other Electra Elite
IPK ETUs and must be programmed using Memory Block 7-1 (Card Interface Slot
Assignment).
The following procedure provides the general directions for Electra Elite IPK
programming for the ETU Interface Slot Assignment.
1. From port 01 or 02, enter the programming mode.
2. Press A, H,
L , K and J .
3. Assign the Card Interface Slot Assignment by pressing LK7 and LK1.
4. Press
A , B or C for the cabinet number of KSU where the IAD(8)-U( )
ETU is installed.
5. Press
L to move the cursor to the right.
6. Enter slot number (1~8) of the KSU containing the IAD(8)-U( ) ETU.
7. Press Cto change the page number (Page 2).
8. Assign the ESI ETU and select LK1.
9. Press Gto write the data.
10. If assigning the telephone type and station number:
H Assign the telephone type by pressing LK7 and LK2. (If assigning the Megaco
terminal, assign the port as: TEL = LK2.)
H Assign a station number on a per port basis. (Elite KSU Programming MB 4-10)
 PC Programming can also be used to program the Electra Elite IPK system.
When programming the key telephone system, the IAD(8)-U( ) ETU (Megaco
Station) is always assigned as an ESI(8)-U( ) ETU.
