Modem Template Properties

The following table describes the properties displayed in the details pane for a modem template. Use this table to help you interpret and enter data in the details pane.

You might also need to consult your external device documentation.

Property

Definition

Access ID

Provides the Telocator Alphanumeric Protocol (TAP) access-id expected by your paging service.

The access-id has the format:

sstnnnnnn

where:

ss is the service type

t is the terminal type

nnnnnn is the password (usually not used)

The default value is PG1000000. For the appropriate string to use, consult your paging service.

Dial Response

Indicates how the modem is expected to respond to the telephone dial. Use the arrow () in the Dial Response property to select one of the following values:

  • None

    No response is expected from the modem.

  • OK

    A zero (OK) status is expected from the modem.

  • Connect

    A connection status (indicating a successful connection to another modem) is expected from the modem.

Connect is the default value.

If you select TAP as the Protocol property, Connect is automatically selected as the Dial Response property value and you cannot change it.

Dialing String

Provides the Hayes modem syntax used to instruct the modem to dial a number and make a telephone connection. Operations Sentinel sends the value you enter to the modem to dial a telephone number and establish a connection.

The dialing string typically has the format:

ATDT9,18006792778

where:

AT is the command prefix (it precedes most commands).

D dials the telephone.

T is used for tone dialing.

9 is the number to get an outside line.

, is used to pause before dialing the number. 18006792778 is the number to dial (in this example).

For the appropriate string to use, consult your modem documentation.

Hang Up

Provides the string used to hang-up the telephone line after a message has been sent. Operations Sentinel sends the value you enter to the modem to hang up the connection.

A typical value is ATH, where:

AT is the command prefix. H hangs up the telephone.

Do not specify a value for this property if your modem does not require a hang up message.

Network Name

Provides the Internet network name of the terminal/communications server that is connected to the modem. The network name must be in the hosts file on the Operations Sentinel server (SystemFolder\drivers\etc\hosts), in the Domain Name Server, or in the Windows Internet Naming Service. See the Operations Sentinel Administration and Configuration Guide for more information on host files.

Do not specify a value for this property if the modem is directly connected to the Operations Sentinel server.

Initialization

Indicates the initialization data that must be sent to condition the modem before it is used to communicate. Operations Sentinel sends the initialization string to the modem to initialize it before performing the remainder of any action that refers to this template.

This is typically used to disable data compression and error correction when connecting to a paging service modem. For example, AT&K6&Q6X4 is an initialization string for Practical Peripherals modems.

For the appropriate string to use, consult your paging service and your modem documentation. Do not specify a value for this property if the modem does not require initial conditioning.

PINs

Provides a list of personal identification numbers (PINs) to be used if you select TAP as the Protocol property value. Each PIN accesses an alphanumeric pager and is assigned by your paging service. The number usually corresponds to the phone number assigned to the pager and not the manufacturer’s PIN. Specify more than one value to apply any action associated with this template to multiple pagers.

If you select None as the Protocol property, the PINs property values are ignored and are not saved when you save an alert policy.

To enter personal identification numbers, click the ellipsis ().

See Define the PINs Property for additional information.

Protocol

Indicates the message protocol used. Use the arrow () in the Protocol property to select either

  • None

    Indicates no protocol. This is typically used to support digital pagers and is appropriate when the message can be sent using an ASCII string. The values you specify for the PINs and Access Id properties, if any, are ignored.

  • TAP

    Indicates the Telocator Alphanumeric Protocol. This is required by many paging services to communicate with alphanumeric pagers such as the Motorola Advisor. If you select TAP, you must also specify the personal identification numbers used by the paging service to identify individual pagers.

Retries

Indicates the number of times to retry when the action does not result in a successful connection because of a busy response, no answer to the Dial String, or other condition. There is a 10-second wait between each retry. A value of 0 means there are no attempts to retry the connection. The default value is 0.

Service Name

Provides the name from the services file that identifies the destination service address for actions that use this template. For example, the service name can designate the RS-232 serial port to which an external power control device is connected. You must create an entry for this service name in the services file on the Operations Sentinel server if one does not already exist. See the Operations Sentinel Administration and Configuration Guide for more information on the services file.

If you also specify a network name for the template, the service name refers to a port on the terminal/communications server identified by that network name, which is connected to the modem. The default line characteristics for the port are determined by the terminal/communications server port configuration. If you do not specify a network name, the service name refers to a port on the Operations Sentinel server that is directly connected to the modem.

Operations Sentinel assumes the following default line characteristics for the device being connected to the server’s port.

  • 8-bit character size

  • No parity

  • 1 stop bit

  • 9600 baud

You can change these values using alias parameters for the service in the services file.

If you do not specify a value for the Service property, any action using this template always fails and an event is recorded in the log SP-EAI on the Operations Sentinel server. You can examine this log using the Operations Sentinel Log Viewer.

Name

Provides the name of the modem template. The name you specify should be unique and distinguish the template from others. A unique name facilitates the copying of templates across multiple alert policies.

You can rename a template by editing this property.

Type

Displays the type of template. For a modem template, the value is always Modem. This property is read-only.
