ITG Basic Unit Installation and Reference Guide
Setting Up the ITG
This section describes the processes for setting up your Internet Telephony Gateway once it has been installed. Microsoft Explorer version 4 or higher, or Netscape Navigator version 4.5 or higher can be used in this section to view and change any setting parameters.The main screen is as the following:
The followings describes the settings that can be changed and personalized to best suit the environment in which you use your Internet Telephony Gateway. There are five basic settings and a menu for each of the respective settings. They are described below:.
4.1 Telephone Mode Settings
The option "Telehpone Mode Settings" helps to setup the basic parameters between your ITG and your analog devices. Click on the button and shows the help screen.
Select the port from the upper frame and click on button "Select", the scrren as below should apprared.
There are six different settings in the Telephone Mode Setting Menu that can be changed.
They are the following:
Channel The parameters include eight channels that can be chosen to make changes in.
Each individual channels parameters can be changed.Gain (Receive) The reception gain from telephone sites can be changed or adjusted here. The parameters range from 14 to 14 db.
The default setting is 1 db.Gain (Transmit) The transmission gain to telephone sites can be changed or adjusted here. The parameters range from +14 to 14 db.
The default setting is 1 db.Comfort Noise Level This comfort noise level can be changed or adjusted here. This setting sets the low level or comfort noise for/when no speech is in progress.
The default setting is -65 dbm.Tone Dial-Out Type The tone dial-out type can be changed here. Either tone or pulse can be selected.
The default setting is on tone.Tone Detection Threshold The call progress is used to indicate the status of your call, whether your call is dialing, in progress, or busy. For an abnormal detection of a call session, Call Progress (CP) Tone Detection is used to automatically tear down the session.
The threshold level is provided to fit different conditions of telecommunication environments. The parameter of the CP is 20 to 35.
The default setting is 28.
4.2 H.323 Configuration
The H.323 Configuration options help in the H.323 protocol stack setup. Up to eleven (11) fields are configurable, depending on the needs.
- Display Name:
This field is to set the display name information that is carried in the H.323 setup messages. Up to 48 characters can be entered, and the default string is Customer.
This message will be used for receiver to identify the caller's name. For example the receiver like Microsoft NetMeeting will display this name, i.e. Customer, to promote the receiver accept the call or not.
- H.245 Terminal Type:
This field is to set the H.245 terminal type, which is used as part of the master/slave determination process of H.245. Typically, setting a value of less than 50 will force slave operation, and a value of greater than 200 will force the master operation. The default value is 60.
A table is listed below.
Terminal Type value table H.323 entity Feature Set Terminal Gateway Gatekeeper MCU Entity with No MC 50 60 NA NA Entity contains an MC but no MP 70 80 120 160 Entity contains MC with data MP NA 90 130 170 Entity contains MC with data and audio MP NA 100 140 180 Entity contains MC with data, audio and video MP NA 110 150 190 For more details, please refer to H.323-related standard documents.
- RTP Port Base:
This field is to select the starting port number for assignment of RTP and RTCP ports. According to the H.323 specification, RTP port number should be even in value, and the RTCP port number should be one greater than the RTP port.
Typically, numbers from 0 to 1023 are reserved on most systems. The default value is 30000.
- Fast-Start Mode (Outgoing Side):
This field is to enable or disable the Faststart mode on the outgoing side of the link. The default setting is off.
- Fast-Start Mode (Incoming Side):
This field is to enable or disable the Faststart mode on the incoming side of the link. The default setting is off.
- Gate Keeper Mode:
This field is to select the co-operation mode with some gatekeeper(s). Three options available:
- off: disables gatekeeper co-operation,
- auto: enables auto-discovery of the gatekeeper, and
- manual: enables gatekeeper co-operation in manual operation (the gatekeeper address must be properly assigned).
The default setting is off.
The following fields must be filled up when the Gate Keeper Mode is set to either auto or manual.
6-1. Gate Keeper Address:
Specify the gatekeeper address when configured to manual mode. When auto mode is desired, this field should be set to auto.
6-2. Allow Calls Without Gate Keeper:
This field is to inform the H.323 stack to allow calls when the endpoint is not registered with a gatekeeper.
6-3. Maximum Registration Tries:
This field is to control how many registration attempts will be made before the endpoint considers itself to have failed registration.
6-4. Endpoint Registration Type:
This field is to set the endpoint registration type. This specifies how the endpoint will register itself with the gatekeeper.
6-5. Alias:
This field is to create or delete aliases that are registered with the gatekeeper.
4.3 IP Address
SettingThe Internet Telephony Gateway IP address can be changed here. You may set it to fit your local network and sub net mask.
Note: The new IP address will take effect only after you reboot your system.
4.4 Dial Plan Setting
The dial plan is set up and/or changed here. Basically, the concept of the dial plan is the group or region.
4.4.1 Group - Calls to Local port
A group is a set of telephone numbers called from the IP network to local channels that calls a specific working group. For example, there may be five phone numbers configured for an R&D Group, and ten other phone numbers for the Technical Support Group. The maximum group number depends on the product type you have, that is, whether it is a 4-channel product or one module installed- which can support up to four groups, or an 8-channel, two module installed- which can support up to eight groups.
Ten (10) phone numbers are accepted for each group, where each number can be up to 20 digit.
In this example, the port 1 of your ITG accept remote call with the number or the number with the prefix number above. That is, if your ITG get a remote request with the number say, 011-567-1234, or 011. Your ITG will accept the request using port 1 since "011" is in the list.
This will come into two results according to the module installed.
To a FXS module, the port 1 will activate the connected device, for example, make a ring to the KTS (Key Telephone System).
To a FXO module, the port 1 will activate the connected device according to the number it gets and also with the parameters below.
In this example, if the stripped off digit is "3" with number "011-567-1234" from remote, ITG will send the number "5671234" to the connected device. I.e. call out with number 567-1234 if the connected side is your local PSTN.
Or, if stripped digit is three and prefix with "555", the ITG will use port 1 to call to your extension number "555" if the remote number is "011" and your are connecting your port 1 of the ITG to your PBX internal line or call out using 555-567-1234.
To click on "Save the Changes" will save the setting to your ITG and promote the settings.
4.4.2 Region - Calls to IP Networks
A Region is an area where a remote call can be placed. For example, in the United States, we can use the Area code as the region indicator, e.g. 408 for the San Jose Region. Within any given region, only one IP address is required. If you have ten different phone numbers with the same Area code, a single IP address can accommodate them all.
There are two buttons available in this screen, "List all Region" and Region "select".
4.4.2.1 List All Region
After click on "List All Region", your ITG will show you all the IP address recorded. You can then select the IP netwrok or "Add a New Region"
The "Add a New Region" button will locate and display an available blank table. Up to 50 IP regions are available.
4.4.2.2 IP Network Setup
Four parts available for IP Netowrk Settings.
1. IP Address Region:
The IP address of the H.323 end node, this IP address should be a legal IP address for your ITG to reach the receiver. Incorrect IP address will failed in making the phone call.
You can direct modify the IP address, or to delete the region, leave the field blank and save the changes.
2. Company / Location Description:
This field is used to describe the regions. Up to 31 chacters ("A"-"Z", "a" - "z", and ASCII characters except space) are allowed.
3. Phone Numbers:
The same with "Calls to Local Port", ten phone numbers are available and up to 20 digits accepted for each number.
4. Dial Parameters:
The same with "Calls to Local Port" number, the stipped number and prefix number fields will modify the call before send the request to the remote IP address.
4.5 Password Change
You may choose to change the default User ID and Password here at anytime during or after the initial set up stage.
After save the changes, you will need to reload the Web screen with the new ID and password.
