Configuring the Modem at the SRX550 Services Gateway End

 

Before you can connect a dial-up modem to the console port on the SRX550 Services Gateway, you must configure the modem to accept a call on the first ring and to accept DTR signals. You must also disable flow control on the modem.

Note

These instructions use Hayes-compatible modem commands to configure the modem. If your modem is not Hayes-compatible, refer to the documentation for your modem and enter equivalent modem commands.

To configure the modem on the services gateway end:

  1. Connect the modem to the management device (a desktop or laptop computer).
  2. Power on the modem.
  3. From the management device, start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal), and select the COM port to which the modem is connected (for example, COM1).
  4. Configure the port settings, as shown in Table 1.

    Table 1: Port Settings

    None

  5. In the HyperTerminal window, type AT.

    For more information on the AT commands, see the Initial Configuration for Security Devices.

    An OK response verifies that the modem can communicate successfully with the COM port on the management device.

  6. To configure the modem to answer a call on the first ring, type ATS0=1.
  7. To configure the modem to accept modem control DTR signals, type AT&D1.
  8. To disable flow control, type AT&K0.
  9. To save modem settings, type AT&W.
