General ISDN Parameters

Parameters

Description

ISDN Mode

Off	The ISDN interface is deactivated.
In/out	The camera can answer a phone call and dial out to the Internet (e.g. for transferring an image to an FTP server) at the same time.

Only data calls	The camera can dial out to the Internet (e.g. for transferring an image to an FTP server). The camera does not accept incoming phone calls.

Termination Reboot

The factory default setting for this feature is off.

Incoming Calls

Parameters

Description

Accepted MSN

The MSN (Multiple Subscriber Number) is the telephone number used to call the camera. By its factory default settings, the camera will answer to every MSN that is called on the ISDN S0 bus.

Set the MSN you would like the camera to react to.

Every	The camera answers to every MSN valid for this ISDN S0 bus.
Next called	When the camera is connected to a telephone system, the MSN can differ from the telephone number. The camera reacts to the next called MSN and sets it automatically.
(Enter MSN manually)	Enter the MSN of the ISDN port you would like the assign to the camera. When the camera is connected directly to an NT, enter the MSN without prefix.

Store the settings and reboot the system and the camera will only react to the registered MSN or the one it has set automatically.

Note:	The easiest way to determine the correct MSN is to select the Next called option and then call the camera.

Allowed Phone Numbers

The camera can be configured to either react to all incoming calls or only to the telephone numbers entered here.

In order to create a list of the accepted telephone numbers, enter the numbers in the text box, separated by spaces.

Camera IP Address

The camera uses this IP address for ISDN connections. It can vary from the IP address of the network interface. It is recommended to only change the ISDN IP address with good reason.

By the factory default settings, the ISDN IP address is identical to the IP address of the network interface.

Caller IP Address

This IP address is assigned to a computer that dials into the camera via ISDN. Make sure that this address has not yet been assigned to another device within your local network. The caller IP address has to be be different from the ISDN IP address.

Idle Time

In order to minimize telephone costs, the camera can terminate an ISDN connection if it does not detect data traffic within the period of time specified here.

Authentication

It is recommended to always select an authentication protocol. Most computers understand both protocols. Other than PAP, CHAP transmits encrypted user name and password information.

Camera Login

For successfully logging into the camera, you need to enter a user name and password.

Note:	It is recommended to replace the factory defaults by specifying your own user name and password.

Outgoing Calls

Parameters	Description
Number to Call	Enter the telephone number the camera will use for dialing out. Your Internet provider or administrator will provide the correct number.
Outgoing Gateway	Do not change this entry. When the connection is active, the called computer sets this address automatically.
Idle Time	In order to minimize telephone costs, the camera can terminate an ISDN connection if it does not detect data traffic within the period of time specified here.
Authentication	For the camera to successfully establish a data connection with the provider, enter a valid user name and password in these text boxes. Your Internet provider or administrator will provide this information.
Dialing Pause	Set the time in seconds for the camera to wait between two dial attempts.
Dial-Out Limits	Using the dial-out limits helps you limit the costs of ISDN operation. For doing so, you can set different limits which, once reached, will block any dialing-out action: Time limit in seconds for day, week, month Number of connections for day, week, month
