All New SNMP Implementation Guide Gives Practical Step-By-Step Advice for Converting Your Network to SNMP
If you want to know more about SNMP, you're not alone. Telemetry professionals are hungry for information about SNMP, as shown by the interest in our SNMP Tutorial series, which has been viewed and downloaded over 50,000 times and counting.
|Bob Berry, President & CEO
The SNMP Tutorial has been a great educational resource, but I thought it was time to supplement it with a real nuts-and-bolts, step-by-step guide to what you need to do to make SNMP alarm monitoring work for your network.
This new white paper, "How to Implement SNMP Monitoring in Your Network: A Practical, Step-by-Step Guide" is now available for download, free to Protocol subscribers.
New Product Announcement: The Critical Alarm Enunciator Provides Local and Regional Notification of Battery Plant Voltage Levels
|The Critical Alarm Enunciator provides local notification of alarms.
At remote sites, nothing is more critical than maintaining a constant power supply to your revenue-generating equipment. When the power goes, everything goes with it, so monitoring your battery plant voltage levels is the most important telemetry job you can do.
The new Critical Alarm Enunciator (CAE) is the right tool for monitoring mission-critical battery levels. The CAE monitors three battery plant voltage threshold alarms and three discrete alarm, provides audiovisual notification to local personnel, and then relays alarms to your NOC via your existing alarm collection equipment.

New York City Transit's $141 Million Project to Create an ATM/SONET Network for the 21st Century
|NYCT Engineering Team at Siemens factory acceptance tests in Florida.
Carrying over 4 million passengers on an average weekday, the New York City subway system places huge demands on its internal signal, control, and communications network—which, like the trains, must run 24 hours a day, every day of the year.
To meet these demands and create increased capacity for future services, the New York Transit Authority (NYCT) has undertaken a proactive project to create a new network for the 21st century. The $141 million project will upgrade a key fiber optic network connecting 188 subway stations across Manhattan, Queens, Brooklyn and the Bronx to an ATM/SONET voice and data network.
Of course, providing these services requires the highest levels of system reliability.
Why implementing network reliability management is an essential part of this project...
Application Feature: Four Ways Your IAM Can Automate Network Management
|The IAM-5 and The NetGuardian 832A support derived alarms, which correlate diverse alarms and trigger automatic correction responses. The flexibility of derived alarms support a variety of advanced network monitoring applications.
Derived alarms and controls are one of the most powerful features in T/MonXM. Derived alarms are "virtual" alarms created through user-defined formulas that coordinate inputs from several alarm points and apply logical operators to them. One classic example of a derived alarm is the combination of a low battery AND a broken generator. Either condition isn't only a Major alarm by itself, but in combination they are a Critical alarm.
The value of derived alarms is that they provide a way for you to watch for alarm combination scenarios. You don't have to scan your monitoring screens to figure out what's happening with your network. If you've configured your derived alarms, you've told T/MonXM what to watch for, and it will keep track of your alarms for you.
- Notification when scheduled events do not happen when they should.
- Operate a secondary notification device.
- Notification of LAN failure using a heartbeat alarm.
- Notification of events that are only alarms when they happen at a certain time.

QuickTips: How to Send an IAM Heartbeat Alarm to an Upper-Level Master
|Configure Your IAM to Send a Heartbeat Alarm
in telemetry monitoring, the information
you most want to see is a simple positive
confirmation that your monitored devices
are up, running, and connected to your
is no problem if you're using one of the
many alarm monitoring protocols that support
polling, in which the master actively
verifies communication between it and
remotes. But there are many widely used
protocols, like SNMP and SCADA, that don't
In these protocols, communication between
remotes and the master is initiated by
the remote only if it has an alarm to
report. Silence from the remotes usually
means all is well —
but sometimes it means the communication
lines have broken down completely.
