Dial-up Connections

Routing via Fixed Links

Remote hosts are machines not connected to your local network. These can be reached via a fixed link (attached to the synchronous port (B) or another router on your local network), or via a temporary dial-up connection. This section covers temporary dial-up connections and fixed links.

Dial-up Connections

To make dial-up connections you need to connect a modem to a serial port on the IOCOMM:

1. On the IOCOMM Main menu page, select Serial ports configuration.
2. Select the port number to which you have attached the modem.
3. Select Modem options.

   The Modem options (initialisation commands) available on this page are listed below. Entries shown to the right of each field are the IOCOMM factory default settings.

   1st init string	[AT ]
   Response	[OK ]
   2nd init string	[ATV1 ]
   Response	[OK ]
   3rd init string	[ATSO=1 ]
   Response	[OK ]
   Dial string	[ATD ]
   Response	[CONNECT ]
   Modem disconnect	[%D+++%DATH%D ]
   Response	[OK ]

   
   Check that the settings are suitable for your modem.

   Note: Initialisation strings should not contain any commands that may cause the modem to pause operation. For example, the save configuration command on some modems.

4. Select Physical parameters

   Description

   [Asynchronous serial device ]

   
   Note: The Description field is for information only.

   The next options allow you to specify:

   Terminal type	[wyse 50 ]
   Attached device	[Asynchronous terminal ]
   Baud rate	[9600 ]

   
   Note: The Terminal type field is for your information only.

5. For the Baud rate and Attached device options, select the down arrow for an option list and then select the required setting.
6. Check the port boxes to write this configuration to additional ports for which you require the same settings.

   There is also an Expert mode for Physical parameters which offers additional configuration options.

7. Select the Expert button while still in the Physical parameters page.

   You will be presented with the additional options:

   Character framing	[8 data, no parity, 1 stop ]
   Inactivity timeout	[No timeout ]

   
   
   Character framing defines the format of the asynchronous characters on this link.

   Inactivity timeout allows dialled connections to be automatically shut down after a period of no data traffic.

8. For Character framing, select the down arrow and choose from the list.
9. For Inactivity timeout, select the down arrow to view and select the appropriate timeout setting.
   Special wiring options cause the access server to ignore the RS-232 signals DCD or DSR.
   
   Special operations option allows the access server to be used with modems that do not raise RTS until a call is connected.

   
   Special wiring

   DCD ignored/not wired

   DSR ignored/not wired

   
   Special operations required for attached modems

   RTS not raised until DCD present

   
   Flow control parameters

   Hardware flow control

   Software (XON/XOFF) flow control

   None

   
   If required, data flow control can be performed using RS-232 signals or special XON/XOFF characters.

10. Select Check here to reset port and make changes immediate.
11. Select Submit.
12. Select Return to the Main menu.
13. Select Remote sites configuration and then Create new entry.

    Note: Details for the following fields should be obtained from the Remote Host administrator.

14. Enter the Remote host name.
15. Enter the Telephone number of the remote modem.
16. Enter the username.
17. Enter the password.
18. Enter the IP Address of the Remote Host.
19. Enter the IP Netmask of the Remote Host.
20. Select again the port number to which you have attached the Modem.
21. Select Submit.
22. Select Return to the Main menu.

Routing via Fixed Links

You need to create a new entry for each permanent route you wish to create. RIP listening is a more dynamic alternative to these fixed links.

1. On the IOCOMM Main menu page select Static routes configuration.
2. If you have static routes already set up and wish to change one, select the entry for the route you wish to change and edit the entry as appropriate. Select Submit to save the entry.
3. If you do not have any static routes configured or wish to add a new route, select Create new entry. The following fields will need to be completed.

   
   Destination IP

   Enter the IP address of the remote host to which you wish to create a static route.

   Note: You can also specify a host name in this box, but there must be a corresponding DNS entry.

   
   Destination mask

   Enter the appropriate mask value.

   
   Gateway IP

   Enter the IP address for the gateway (router) device.

   Note: You can also specify a host name in this box, but there must be a corresponding DNS entry.

    

4. Select Submit. You will obtain the Static routes configuration main page and your new entry will be listed.
5. If required, create further static routes by selecting Create new entry or quit the page by selecting Return to the Main menu.
