DTMF/Voice Interface: Acknowledge or Tag Alarms with Just a Phone Call

DTMF/Voice Interface
Simplicity and convenience: Ack or tag alarms from a touch-tone phone with the T/Mon DTMF/Voice Interface

The DTMF/Voice Interface for T/Mon NOC lets you acknowledge or silence alarms from the field, using any touch-tone phone. As easy and familiar as a voice-mail system, the DTMF/Voice Interface uses synthesized voice prompts to guide you through a menu of options, and you just select your choice by pressing a phone button.

The DTMF/Voice Interface for T/Mon NOC, combined with T/Mon NOC's built-in support for pager and email notifications, puts easy-to-use, cost-effective, automated tools for 24/7/365 network alarm monitoring within the reach of your company.

If you thought you couldn't afford 24/7 monitoring, T/Mon NOC and the DTMF/Voice Interface gives you an automated 24-hour NOC without the huge costs of keeping a staff and duty after hours and on weekends.

  • Ack or tag alarms from any touch-tone phone
  • No-fuss integration with T/Mon NOC (DTMF On-Call Software Module required)
  • No extra databasing required
  • Two-year warranty
Critical Alarm Enunciator - Applications

How the DTMF/Voice Interface Works:

T/Mon NOC notifies field technicians of new alarms by sending a detailed text message to the techs' alphanumeric pager or email-capable cell phone. The pager message contains an eight-digit ID number that uniquely identifies the alarm.

To acknowledge the alarm, the user calls T/Mon NOC over an ordinary landline or cellular touch-tone phone. A synthesized voice prompts the user to enter the alarm's ID number. The user can then follow the voice prompts to acknowledge or tag the alarm - either individually or all the alarms for that site.

The DTMF/Voice Interface is easy to install in any standard telco environment.
