ISDN Administration

This option is available only if the relevant hardware and software has been installed. (See the system's hardware installation manual for instructions on adding network interface hardware.)

To Add a Remote Host Connection

1. On the Main Administration page, under "Network Connection Administration," click ISDN.

   The ISDN page is displayed.

2. Click Add a remote host connection.

   The Add Remote Host Connection page is displayed

3. Enter the information in the form using the following table.

   Table 7-11 Information for Remote Host Connection

   Option	Description
   Remote Host Address	The host address of the peer side of the ISDN point-to-point link.
   Local Host Address	The host address of the local side of the ISDN point-to-point link. Setting this field to the keyword "dynamic" turns on the negotiate address feature
   Netmask	The number that masks the host component of a host address and thus shows how to divide the network component of the host address into subnetworks.
   Inactivity Timeout	The number of minutes an ISDN connection is allowed to idle before it is disconnected.
   Host Setup Timeout	The number of minutes allowed before an ISDN connection request ceases its attempt to connect to the remote system.
   Default Route	The route entry that allows connections to unspecified hosts to go through this connection. The default route is created when the connection is made with the remote system; it is deleted when that connection is terminated or timed out. Choose On, or Off.
   Bandwidth Controller	The side of the connection that is controlling the number of ISDN links used on the connection. Only one side can be on at a time. Choose On, or Off.
   Encapsulation	The encapsulation protocol used in data transfers. For multilink PPP (MP), the control protocol may or may not be encapsulated. Ascend boxes require control encapsulation, others typically do not. Choose PPP, MP-Ascend, or MP-Other.
   Data Compression	Turn data compression on. Note: Encapsulation must be set to one of the MP options.
   Local Authentication	The authentication mechanism used by the Netra to authenticate incoming calls. Chap Authentication Protocol (CHAP) uses encryption-based password control. Password Authentication (PAP) is similar to CHAP. Choose chap, pap, or off.
   Remote Authentication	The authentication protocol that is used with remote systems. Choose chap, pap, or both.
   ID String	The login string used by the authentication protocol.
   Password	The password string used by the authentication protocol.
   Caller ID	If the incoming call presents its caller ID number, this number is used to find an isdn_path for the incoming call. Choose On, or Off.
   Channel Baud Rate	The B-channel baud rate. Choose data56, or data64.
   Hunt Mode	Sequentially dial through the phone numbers listed for a remote host, until a connection is made or until the list is exhausted.
   Phone Number 1	The phone number to dial to reach the system at the other end of the ISDN connection. Example 17005554141.
   Phone Number 2	An alternate phone number to dial to reach the system at the other end of the ISDN connection. This phone number need only be entered if supplied by the remote system.

To Configure a Local Port

1. On the Main Administration page, under "Network Connection Administration," click ISDN.

   The ISDN page is displayed.

2. Click Configure for the required port.

   The Configure ISDN Port page is displayed

3. Complete the form using the information in the following table.

   Table 7-12 Information for ISDN

   Option	Description
   Switch Type	Specifies the type of switch to which your ISDN line is connected. This information is available from your phone company or Internet Service Provider (ISP). Choices:   au1 (Australia) vn3, vn6 (France) 1tr6 (Germany) ntt (Japan) bt2 (United Kingdom) dms, 5ess, ni2 (North America) etsi (Europe) swd-etsi (Sweden) htk (Hong Kong)
   Force 56kb	Forces the ISDN line to a 56Kb transfer rate regardless of how the incoming call identifies itself. This is mainly used to solve incompatibility problems between switches.
   Calling Line Identify	Enables or disables exchange service (if available) where the exchange verifies that the local calling number is the phone number of the calling system.
   ISDN Number	Your ISDN phone number. This information is used for outgoing calls and specifies the calling number to the remote host.
   ISDN Subaddress	If more than one ISDN device is using the same ISDN line, sub-addressing can be used to address each device. This is an advanced feature; consult the ISDN documentation for details.
   SPID	The service profile identifier. It is used in North America as an additional identifier and in conjunction with the calling number, to identify the local number to the local switch.
   Local Number	Use to "filter" incoming calls. If the calling number of an incoming call does not match this number, the call is rejected. When used, this number should be your ISDN number.
   Local Subaddress	This is an advanced feature and is normally not needed.

   Note -

   Profile B should be used only within the USA.
