ISDN Tab

Usage: Click the Help button at any time to get online help for the settings in the current tab.

This opens a World Wide Browser, such as Netscape Navigator or Internet Explorer, and displays information about the settings.

To close the help display, close the browser as you would any other program. For example, in Windows 95, click the X button at the upper right of the window or choose Exit from the File menu.

With some browsers, a new window will open each time you click the Help button. If this happens, simply close each window when you're done with it.

Finding setting descriptions: At the beginning of each help window is a table of contents for the window. To go information about a particular setting, click the hyperlink (the underlined text in most browsers) for that setting in the contents. To return to the contents, use the control in your browser for going back, such as the Back button in Netscape Navigator or Internet Explorer 3.0.

Usage: Click this button to send the settings shown in the Java-Based Pipeline Configurator to the Pipeline.

These new settings replace the previous settings in the Pipeline. You can use this button at any time; you do not have to enter values for all settings before updating the Pipeline.

Usage: Click this to save the settings shown in the Java-Based Pipeline Configurator in a file on your computer.

You then use your operating system's facility for specifying a name and location for the file, such as the Save To dialog box in Windows 95.

You can later open a file in which you've saved settings by clicking the Open a Configuration File button in the first window that appears when you run the Java-Based Pipeline Configurator.

You can use this button at any time; you do not have to enter values for all settings before saving settings.

Usage: Click this to open the Pipeline Monitor.

Usage: Choose one of the following:

Dependencies: Keep this additional information in mind:

• The Switch Type setting does not apply to a link using inband signaling (Call Type setting is 56K or 56KR) or consisting entirely of nailed-up channels (Call Type setting is Nailed).

  For inband signaling, a line uses 8 Kbps of each 64-Kbps B channel for WAN synchronization and signaling. The remaining 56 Kbps handle the transmission of user data.

• All switch types outside of North America except German operate in multipoint mode.

Usage: Choose one of the following:

• Switched
  This is the most common type of service. With switched service, the Pipeline dials a telephone number to make a connection to a remote network. In addition, remote ISDN devices can connect to the Pipeline by dialing a telephone number.

• Leased
  With leased service, the Pipeline has a permanent connection to a remote network. There is no telephone number for the B channel.

• Unused
  Unused means that the B channel is not used. The Pipeline can use only the other B channel, which limits the speed of data connections to 64 Kbps.

Usage: The phone number can include any of these characters:

1234567890()[]!z-*#"

You can include a hyphen in the phone number but not spaces.

Example: 5105551972

Dependencies: Keep this additional information in mind:

• You get this number from the telephone company providing your ISDN service. There is no telephone number for leased service.

• When the Pipeline receives a multichannel MP+ call, it reports the primary phone number (Number A) and the secondary phone number (Number B) to the calling party. The calling Pipeline can then add more channels. If you do not specify a phone number and the calling Pipeline needs to add more channels, it redials the phone number it used to make the first connection.

A SPID is typically formed by adding a code to the phone number assigned to the line. Your phone company provides you with one or more SPIDs.

Usage: The SPID can contain up to 16 characters.

Dependencies: Keep the following additional information in mind:

• For ISDN service in North America, you must enter a value for SPID A unless you have AT&T Custom Point-To-Point service for your ISDN line. If the value of Switch Type is AT&T Point-to-Point, there are no SPIDs for your ISDN line.

• If the Pipeline uses only one channel of a multipoint ISDN BRI line and another ISDN device uses the other channel, set Usage for one B channel to Unused and enter a SPID for the B channel that the Pipeline uses. Use the second SPID for the other ISDN device.

• The Pipeline appends a terminal identifier (TID) to the SPID if you are connected to a Northern Telecom switch running NI-1.

Usage: Choose one of the following:

• Switched
  This is the most common type of service. With switched service, the Pipeline dials a telephone number to make a connection to a remote network. In addition, remote ISDN devices can connect to the Pipeline by dialing a telephone number.

• Leased

Usage: The SPID can contain up to 16 characters.

Dependencies: Keep this additional information in mind:

• For ISDN service in North America, you must enter a value for SPID B unless you have AT&T Custom Point-To-Point service for your ISDN line. If the value of Switch Type is AT&T Point-to-Point, there are no SPIDs for your ISDN line.

• If the Pipeline uses only one channel of a multipoint ISDN BRI line and another ISDN device uses the other channel, set Usage for one B channel to Unused and enter a SPID for the B channel that the Pipeline uses. Use the second SPID for the other ISDN device.

• The Pipeline appends a terminal identifier (TID) to the SPID if you are connected to a Northern Telecom switch running NI-1.

SPIDs identify devices connected to the ISDN line. All types of ISDN service in North America except AT&T Custom Point-to-Point use SPIDs to specify the device that receives an incoming call. When you order ISDN service for a Pipeline, you normally get two SPIDs, one for each telephone number.

Each SPID for a Pipeline can identify more than one device. It identifies the Pipeline when the corresponding telephone number is used for an incoming data call. It identifies a telephone or other analog device when the device uses the corresponding telephone number for an incoming voice call. This sharing of SPIDs is possible because a single telephone number can handle data or voice, but not both at the same time.

See the descriptions of the Phone 1 Usage and Phone 2 Usage settings for information on using the same SPIDs for voice.

The proper value for this setting depends on the telephone switch and type of ISDN service for your ISDN line.

• For an AT&T 5ESS switch providing either National ISDN-1 (NI-1) or AT&T Custom Multipoint service, you can specify either or both SPIDs for incoming data calls. Because the 5ESS can use a single telephone number for all data calls, including simultaneous calls to different locations, you can specify just one SPID--which is associated with one of the two telephone numbers--to be used for all incoming data calls. In this case, the other SPID is never used for data calls, and the telephone number that corresponds to it remains available for use by an analog device on that telephone number, such as a telephone or fax machine.

  The drawback is that if the telephone number is being used for a voice call--which can happen if there are analog devices connected to both Phone ports--it cannot also be used for data, and an incoming call to that telephone number receives a busy signal.

  If you specify both SPIDs--A + B--data calls can be received on either telephone number. If one of the Phone ports is in use, the call can be received on the other telephone number.

• AT&T Point-to-Point service does not use SPIDs. Because of this, the Data Usage setting is dimmed if the Switch Type setting is AT&T Point-to-Point.

• For ISDN services provided by Northern Telecom DMS-100 switches, each telephone number can handle only one of the two B channels needed for 128Kbps data connections. To handle incoming data calls that use both telephone numbers, you must set Data Usage to A + B, which makes the SPIDs corresponding to both telephone numbers available for data calls. Specifying just one SPID for incoming data calls limits the data connection to a single B channel.

• A + B
  This allocates both SPIDs to data usage.

• SPID A
  This allocates SPID A to data usage.

• SPID B
  This allocates SPID B to data usage.

• AT&T Point-to-Point service does not use SPIDs. Because of this, the Data Usage setting is dimmed if the Switch Type setting is AT&T Point-to-Point.

SPIDs identify devices connected to the ISDN line. All types of ISDN service except AT&T Custom Point-to-Point use SPIDs to specify the device that receives an incoming call. When you order ISDN service for a Pipeline, you normally get two SPIDs, one for each telephone number.

Each SPID for a Pipeline can identify more than one device. It identifies the Pipeline when the corresponding telephone number is used for an incoming data call. It identifies a telephone or other analog device when the device uses the corresponding telephone number for an incoming voice call. This sharing of SPIDs is possible because a single telephone number can handle data or voice, but not both at the same time. The description of the Data Usage setting explains how to use the same SPIDs for data.

Usage: Choose one of the following:

• SPID A
  This routes incoming voice calls for the telephone number corresponding to the SPID A setting to the Phone 1 jack. This is normally the telephone number specified by the Number A setting.

• SPID B
  This routes incoming voice calls for the telephone number corresponding to the SPID B setting to the Phone 1 jack. This is normally the telephone number specified by the Number B setting.

• None
  This prevents analog calls from being routed to the Phone 1 jack.

• AT&T Custom Point-to-Point service does not use SPIDs. Because of this, the Phone 1 Usage setting is dimmed for Custom Point-to-Point service. With Custom Point-to-Point service, the Pipeline can handle only one voice call at a time. An incoming voice call is always routed to the Phone 1 jack.

SPIDs identify devices connected to the ISDN line. All types of ISDN service except AT&T Custom Point-to-Point use SPIDs to specify the device that receives an incoming call. When you order ISDN service for a Pipeline, you normally get two SPIDs, one for each telephone number.

The Description of the Data Usage setting explains how to use the same SPIDs for data.

Usage: Choose one of the following:

• SPID B
  This routes incoming voice calls for the telephone number corresponding to the SPID B setting to the Phone 1 jack. This is normally the telephone number specified by the Number B setting.

• SPID A
  This routes incoming voice calls for the telephone number corresponding to the SPID A setting to the Phone 1 jack. This is normally the telephone number specified by the Number A setting.

• None
  This prevents analog calls from being routed to the Phone 1 jack.

• AT&T Custom Point-to-Point service does not use SPIDs. Because of this, the Phone 2 Usage setting is dimmed for Custom Point-to-Point service. With Custom Point-to-Point service, the Pipeline can handle only one voice call at a time. Incoming voice calls are always routed to the Phone 1 jack.

When ISDN service is provided by a Northern Telecom DMS-100 switch, each B channel is associated with a particular telephone number. Because of this, when a B channel is in use, its telephone number is not available. If Phone Number Binding is set to No, an outgoing call that would normally be made on a particular telephone number can be made on the other telephone number if the B channel for the first telephone number is already in use and the B channel for the second telephone number is free.

If outgoing calls must come from a particular telephone number to be identified by Caller ID, setting Phone Number Binding to Yes ensures that the call is made using the telephone number for the port to which the device is connected. If the B channel for this telephone number is already in use, the call cannot be made.

When Phone Number Binding is dimmed, any call originated at the Pipeline is associated with the phone number set in the Data/Phone Usage settings. If the outgoing call is a data call and Data Usage is set to A+B, the data call will be placed from the first available phone number.

Usage: Choose one of the following:

• Yes
  This means that an outgoing call is always made on the telephone number for the port to which the device is connected. If the B channel for this telephone number is already in use, the call cannot be made. Set this to Yes only if calls must be made on a particular telephone number to be identified by Caller ID.

• No
  This means an outgoing call that would normally be made on a particular telephone number can be made on the other telephone number if the B channel for the first telephone number is already in use and the B channel for the second telephone number is free.
