Subnet Mask: (Default value: 255.255.255.0)
Enter the Subnet mask for the IAD(8)- U( ) ETU. This is the same one you have been
using on your subnet.
Starting RTP Port Number: Default value: (49150)
Use this field to specify the RTP port number to be used. NEC recommends leaving this
field at its default value, unless otherwise required by the network administrator.
Country: (Default value: North America)
Choose the country where this card will be operating. When operating the card in the
United States and Canada choose North America.
Media TOS: (Default value: C0)
IAD(8)-U( ) sets this value (in Hex) in the 1-byte TOS field for outgoing voice RTP
packets. Refer to IETF RFC791 and subsequent RFCs describing the usage of TOS field
in the Internet.
Signaling TOS: (Default value: C0)
IAD(8)-U( ) ETU sets this value (in Hex) in the 1-byte TOS field for outgoing Megaco
messaging UDP packets. Refer IETF RFC791 and subsequent RFCs describing the
usage of TOS field in the Internet.
Page Timeout: (Default value: 10 minutes)
The page timeout setting applies to the time Web Configuration Utility remains active.
Ethernet Interface (Default value: Auto Negotiate)
The Ethernet Interface setting allows for manual configuration of the Ethernet port
connection mode. This can be set to operate in the following port speed and duplex
mode: 10MB/Full Duplex, 100MB/Half Duplex, and/or 100MB Full Duplex. At default, this
will be set to Auto Negotiate. When set to Auto Negotiate, the IAD card will sense the
peer connection (wherever the cable is connected to (e.g. Hub, Switch, or Router)
hardware capabilities and negotiate the best possible speed and operation mode.


Firewall IP Address:
Enter the IP Address of the Firewall Router that the IAD(8)-U10 ETU is placed behind.

___________________________________________________________________________________
A - 4
When set to Auto Negotiate, make sure that the peer (the other side of the Ethernet
cable) is capable of Auto Negotiate (some Routers may not have this feature).
When set to a default other than Auto Negotiate, make sure that the peer is configured
to operate in the same manner. Speed and duplex mode must match on both sides of
the cable.
The Firewall Router should be configured to forward all packets that are destined for the
IAD(8)-U10 ETU.
