7.2. ISDN Diagnostic Program

When using Springware boards, the ISDN Diagnostic program (isdiag) is an interactive tool used to help verify ISDN line operation and to assist in troubleshooting the network trunk. When your application is ready for final installation, running this diagnostic program can help in determining what the network carrier is expecting first.

Note: The ISDN Diagnostic program (isdiag) is not supported when using DM3 boards.

With the ISDN Diagnostic program running, a trace on the inbound call will detect what the network sent. A trace on a failed outgoing call will show the cause of the failure.

When the ISDN Diagnostic Program is first started, users identify the specific board, channel number (time slot), bus type (SCbus), and board type (T-1 or E-1) on which outgoing calls will be made. Incoming calls may be received on any time slot. For a Linux application, you can use the F1 key to bring up the help screens and for a description of the menu items.

To run the diagnostic utilities:

1. Enter:

isdiag parm1 parm2 parm3 parm4  

where:

• parm1 - is the board number
• parm2 - is the channel time slot number
• parm3 - is the interface type (t for T-1 and e for E-1)
• parm4 - is the bus type (S for SCbus)

2. After the channel number and bus mode are selected, the program automatically configures the system and displays the first level menu.
3. Select from the following actions:
   • set outbound call parameters
   • request calling party number (ANI)
   • send maintenance request
   • display information (called party subaddress, user-to-user information, B and D channel status)
   • drop call
   • make outbound call
   • play and record 24K voice files
   • stop play/record
   • set and get ISDN information elements
   • send message
   • start/stop/browse trace files
   • restart ISDN line devices and set up to receive an inbound ISDN call
   • change the current ISDN line device number
   • shell to Linux [or shell to DOS (Windows)]
   • hold/retrieve calls (DPNSS and Q.SIG protocols only)
   • set supplementary DPNSS/Q.SIG services (intrusion, local diversion, remote diversion, virtual calls for inbound/outbound) (DPNSS and Q.SIG protocols only)
   • ESC exit
   • F1 help menu; describes the main menu options
