Configuring the modem ═══ Prerequisites: To configure the modem you'll need at least: One SPID ( Service Profile Identifier. ) One TEI ( Terminal End Point ID. ) One DN ( Directory Number. ) In addition to the above information: The Switch Type used by your local telephone company. The Protocol Type used by your local telephone company. What kind of calls will be made on each channel. ═══ 2.1. Dialing Method Setting. ═══ There are two options for this setting: Standard analog ( Overlapping ) All digits at once ( en-bloc ) ═══ 2.1.1. Standard analog ( Overlapping ) ═══ The digitis are sent one at the time. This is the standard dialing mode. ═══ 2.1.2. All digits at once ( en-bloc ) ═══ The digitis are not sent unless the '*' character is sent at the end of the dialing process. ═══ 2.2. Call type for B1 ( Analog channel. ) ═══ There are two options for this setting: Speech Modem or Fax ( 3.1Khz audio ). ═══ 2.2.1. Speech ═══ Set this option if you will use the analog port only to make voice calls using a analog telephone. ═══ 2.2.2. Modem or Fax ( 3.1 Khz audio ) ═══ Set this option if you will be using fax machine or analog modem connected to the analog port. This type of call is also reffered to as 3.1 Khz audio. ═══ 2.3. Call type for B2 ( Data channel. ) ═══ There are six options for this setting: Automatic Service Choice. V.120 rate adaptation calls only. V.110 rate adaptation calls only. Modem or Fax emulation only. Clear-Channel synchronous calls only. Internet access mode ═══ 2.3.1. Automatic Service Choice. ═══ Automatic Service Choice. The modem will try to make a V.110 ( asynchronous, rate adapted to 64Kbps ) connection. If a V.110 connection can't be made it tries a V.110 connection ( depending on the value of S-Register 67 ). If a V.110 connection fails the modem attempts a V.34 ( analog ) connection. If a V34 connection fails the call is negotiated as an analog call ( V.FC, V32Terbo, V32bis, and so on. ) ═══ 2.3.2. V.120 Only. ═══ V.120 Only. The modem will try a V.120 connection. If the V.120 connection fails the modem will not try to connect at any other speed. ═══ 2.3.3. V.110 Only. ═══ V.110 Only. The modem will try a V.110 connection. If the V.110 connection fails the modem will not try to connect at any other speed. ═══ 2.3.4. Modem or Fax Emulation Only. ═══ Modem or Fax Emulation Only. The modem will only make analog calls when this option is selected. In this mode the modem only works in analog mode. Selecting this option reduces the connect time. ═══ 2.3.5. Clear Channel Synchronous Only. ═══ Clear Channel Synchronous Only. The modem sets up a clear channel, 56Kbps or 64Kbps. This option is best suited for videoconferencing and remote access to mini or mainframe computers. ═══ 2.3.6. Internet Access. ═══ Internet Access. This option requires TCP/IP to be installed. This option requires that your software can use a PPP or SLIP protocol. The modem firt tries to make clear channel digital connection by converting the asynchronous PPP stream from your computer to synchronous PPP used by your ISP. If the digital connection fails the modem tries a V.34 ( analog ) connection. If the V34 connection fails the call is negotiated as a standard analog call (V.FC, V32Terbo, V32bis, and so on. ) ═══ 2.4. SPID for B1 and B2 ( Data and Analog channels. ) ═══ Service Profile Identifier. The telephone company should have provided you with one or two SPID numbers ( depending on the service ordered. ) This field can be up to 20 digits. SPIDs tell the telephone company any special services and features to which you've subscribed. ═══ 2.5. TEI for B1 and B2 ( Data and Analog channels. ) ═══ Terminal Endpoint ID. If the telephone company provided this information it should be entered in this field. Otherwise the value should be set to 0 ( dynamic TEI assignment. ) This setting should be in the 0 - 63 range ( 0 is automatic TEI assignment. ) This setting identifies your link with the telephone company. ═══ 2.6. DN for B1 and B2 ( Data and Analog channels. ) ═══ Directory Number. DNs can be 10 or 7 digits, however the Courier I modem accepts only 7 digit DNs. In this case the area code should be ignored when setting this field. ═══ 2.7. Analog signal volume. ═══ Analog signal volume. This option sets the audio volume level for the analog channel. ═══ 2.8. Ring signal volume. ═══ Ring signal volume. This option sets the ring volume level for the analog channel. ═══ 2.9. Protocol Type. ═══ Protocol Type. There are four options for this setting: AT/T 5ESS Northern Telecom DMS-100 National ISDN-1 National ISDN-2 ═══ 2.9.1. AT/T 5ESS. ═══ AT/T 5ESS. Based on the switch type you should choose the protocol type. Switch Make/Model Protocol Type ┌────────────────────┬──────────────────────────────┐ │Northern Telecom │ National ISDN-1 ( PVC 2 ) │ │DMS-100 │ │ ├────────────────────┼──────────────────────────────┤ │Northern Telecom │ PVC 0 or PVC 1 │ │DMS-100 │ │ ├────────────────────┼──────────────────────────────┤ │AT/T 5ESS │ National ISDN-1 (Standard) │ ├────────────────────┼──────────────────────────────┤ │AT/T 5ESS │ Custom │ ├────────────────────┼──────────────────────────────┤ │Other │ National ISDN-1 │ └────────────────────┴──────────────────────────────┘ ═══ 2.10. Bus Configuration. ═══ Bus Configuration. If the switch protocol is AT/T 5ESS Custom then this option should be enabled. Bus configuration refers to how many devices will be on the S/T bus. A line configured for point- to-point expects only one device attached to the S/T bus. A multipoint line can handle more than one device attached to the S/T bus. Point-Point Multipoint ═══ 2.10.1. Point-Point. ═══ Point-Point. The modem requires one DN and no SPID when connected to a point-to-point configured line. ═══ 2.10.2. Multipoint. ═══ Multipoint. The modem requires one DN and one SPID when connected to a multipoint configured line. ═══ 2.11. 5ESS Incoming Call Route. ═══ 5ESS Incoming Call Route. If the switch protocol is AT/T 5ESS Custom then this option should be enabled. Set this option if analog calls should be routed to the modem's data port. If this option is not set all analog calls will be routed to the analog port. ═══ 3. Using the I-Modem Configurator. ═══ Using the I-Modem Configurator. COM1-COM4 Save Settings Test Line Help Exit About ═══ 3.1. COM1-COM4 Radio Buttons. ═══ COM1-COM4 Radio Buttons. Only valid ports will be enabled. When the I-Modem Configurator is loaded it searches for valid COM ports and disables those that don't exist or are in use by other sessions ( such as the mouse. ) ═══ 3.2. Save Settings. ═══ Save Settings. Pressing this button will save the current settings. The new values will not take effect until the 'Exit' or 'Test Line' buttons are pressed. ═══ 3.3. Test Line. ═══ Test Line. Pressing this button will test the ISDN line. The program will iterrogate the ISDN line for 60 seconds. The status of the ISDN line will then be displayed on the test window for every second during the testing phase. If the Physical Interface and the Data Link Layer becomes active before the 60 second timeout the test will end and a '*** Line OK ***' message will be displayed. If the Physical Interface or the Data Link Layer doesn't become active within the testing phase of 60 seconds the test window will display a '*** Line Bad ***' message and the test will end. There are three information fields in the test window: Physical Interface Data Link Layer Test timer. ═══ 3.3.1. Physical Interface. ═══ Physical Interface. This field indicates whether there is a good physical connection between the I-Modem and the telephone company. Valid result codes are: Inactive. No Connection. Active. Good Connection. ═══ 3.3.2. Data Link Layer. ═══ Data Link Layer. The data link layer can be active only if the physical interface is active. An active data link layer indicates that the I-Modem is ready to make and receive calls. Valid result codes are: Inactive. The I-Modem is not ready to make or receive calls. Active. The I-Modem is ready to make and receive calls. Active ( Incorrect SPID ). The telephone company does not recognize the SPID number set for one or both channels. ═══ 3.4. Help. ═══ Help. Pressing this button will bring up the Help window. ═══ 3.5. Exit. ═══ Exit. Pressing this button will result in the termination of this program. If modifications were made to the I-Modem a reset will follow. ═══ 3.6. About. ═══ About. This button will activate the 'About' window.
