Signaling Tos: (Default Value: 0Xc0; Page Timeout: (Default Value: 10 Minutes; Echo Calibration (Default Value: 0; Ethernet Interface (Default Value: Auto Negotiate - NEC Electra Elite IPK II Installation And Maintenance Manual

Document Revision 1 H.323 Trunk
___________________________________________________________________________________

Signaling TOS: (Default value: 0xC0)

IAD(8)-U( ) ETU sets this value (in Hex) in the 1-byte TOS field for outgoing H.323
messaging UDP packets. Refer to 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.

Echo Calibration (Default value: 0)

When a VoIP call is transferred to a 2-wire loop start circuit, it has a potential to
generate large side tone towards the VoIP path. Due to the nature of delays involved
in a VoIP communication network, the side tone can be heard as large echo at the
distant end. The IAD(8)-U( ) trunk. However, as the loop start trunk characteristics
vary depending on the distances from the repeater/CO, further fine-tuning may be
required for optimum echo performance. This field can be used to fine-tune the echo
performance for a given trunk. As a general rule of thumb, if the trunk is "hot'" use the
negative numbers. The hotter the trunk, the larger the negative number.

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.
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).

DTMF Duration: (Default value: 110ms/80ms)

This field is used to set dual-tone multifrequency (DTMF) duration and interdigit time.
H.323 ID: (Default value: neciad)
Enter the ID used by the H.323 protocol for registration with an H.323 gatekeeper.
This field is required if the IAD(8)-U() Card H.323 package uses a gatekeeper. A
maximum of 24 characters.

Use FastStart:

Check this box to enable H.323 version 2 (Faststart). At default H.323 version 1
(Normal Start) is enabled.
