  • Page 11: Chapter 1. Introduction

    For remote access applications, ATLAS receives incoming analog or ISDN-based signals from remote users, concentrated onto T1 or primary rate ISDN circuits. These calls are processed and directed to the Async-232 Module via ATLAS’ inter- nal bussing system. As with all ATLAS components, configuration can be accom- plished through a variety of mechanisms, including Telnet or VT-100 emulation.

  • Page 18: Async-232 Menu Description

    Displays the module type installed in the slot or the module type you plan to install in the slot. If an Async-232 Module is installed, the Type field automati- cally defaults to Async-16. You can use this field to preconfigure a system before installing modules by specifying the module that you want to install into each slot.

  • Page 19: Table 3-2. Async-232 Module Status Messages

    Displays whether there is an alarm condition on the Async-232 Module. Press Enter in this field to activate the Alarm menu. Test Read security: 5 Displays whether the Async-232 Module is executing a test. Press Enter in this field to activate the Test menu. State Read security: 5 Displays whether the module is online or offline.

    Async-232 Module Submenus Info ASYNC-232 MODULE SUBMENUS Figure 3-2 shows the Menu options available for the Async-232 Module. The fol- lowing paragraphs describe these options. (Some submenu headings are abbrevi- ated in the Terminal menu when displayed in column mode.) Figure 3-2.

  • Page 22: I/O Status

    In all fields, the RX direction refers to data flow from the Async-232 Module ports towards the DTE. The TX direction refers to data flow from the DTE towards the Async-232 Module ports. Statistics are kept since the last powerup or reset statistic command.

  • Page 23: Session Status

    Resets all the statistics for a specific port. Session Status Session Status fields display the status of any dial-in or dial-out call for all ports of the Async-232 Module (see Figure 3-6). Descriptions of the available fields fol- low. Figure 3-6. Session Statistics Panel...
  • Page 24 Async-232 Module Submenus Session Status Ring An incoming call has been routed to the Async-232 module port. The call has not yet been answered and the call type is not known. Modem Ringing An incoming analog call has been routed to the port but has not yet been answered.
  • Page 25 Displays a string indicating the reason the last call was disconnected from the port. Disconnect reason messages may also be logged in the ATLAS Event Log or remotely via Syslog by setting the Async-232 severity threshold to Normal or lower. The following fifteen status messages may be present: None No call is active on the port.

  • Page 26: Configuration

    All fields are read and write, although the availability of some fields depends on options chosen in other fields. The Async-232 Module port data format assumes 8 data bits, no parity, and 1 stop bit (8N1).
  • Page 27 DTE Bit Rate Write security: 3; Read security: 5 Selects the bit rate used at the connector between the Async-232 Module port and the DTE. Changing this field hangs up a connected call and requires confirma- tion. Selectable values range from 300 to 115.2 Kbps. Higher bit rates normally require hardware flow control.
  • Page 28 DTE for an incoming call to be answered. If the port is part of a group assigned in the Dial Plan, then the first idle port with DTR active will answer the call. If the DTE drives DTR inactive, the Async-232 Module port hangs up an active call.
  • Page 29 An outgoing call attempts to allocate a modem resource and make Modem an analog call. Asynchronous data is passed unmodified between the Async-232 Module port and the allocated modem. The analog modem resource is freed when the call is hungup. ISDN PPP An outgoing call attempts to allocate an ISDN resource and make a digital call.
  • Page 30 Selected options are issued to the modem when it is allocated to answer an incoming call or initiate an outgoing call. Some options imply a negotia- tion with the remote modem. These modem options may also be specified through the AT command interface if enabled. 3-14 Async-232 Module User Manual 61200182L1-1...

  • Page 31: Test

    Loopback can be Enabled or Disabled for a port with this field. When Enabled, all data received from the DTE by the Async-232 Module port is transmitted back to the DTE. Loopback state is not saved in the module configuration; and, if the card is hot swapped or the ATLAS system restarted, loopback is disabled on all ports.

    232 Module. The Dial Plan menus are only accessible when using terminal mode. To access these options, select Dial Plan from the top level menu. An Async-232 port or range of ports must be assigned in the Dial Plan before it may be used to answer incoming or initiate outgoing calls.

  • Page 34: Figure A-2. Sample Dial Plan

    Ports Available Indicates which of the Async-232 Module’s 16 ports have already been defined in another switched end point (indicated by “s”). Ports which are defined in the cur- rent switched end point are indicated with “!”. Available ports are indicated by a single digit number representing the last digit of the port number.

  • Page 37: Appendix B. At Commands

    AT command mode is not enabled. If the Async-232 Module port is connected to a DTE that echoes all received charac- ters, perhaps as part of a text menu interface, it may be useful to change the escape character or turn it off to prevent entering command mode based on an escape sequence received from a remote modem.
