What This White Paper Will Do for You
The number one question clients ask about SNMP is “How can I use SNMP to do this?” — where “this”
is the alarm monitoring application they care about the most.
You don’t deploy a new kind of alarm monitoring for the fun of it. If you’re thinking about deploying
SNMP in your network, it’s because you have specific problems you need to solve.
This is the book with the specific answers to your specific questions — a quick cookbook of solutions to
show you how you can get your job done with SNMP. For each application, I’ll show you how it works
and what you can do with it.
I’m constantly looking for ways to improve DPS Telecom white papers. If the question most important
to you isn’t in this book, give me a call at 1-800-622-3314. Let me know what you want to know, and
I’ll make sure it’s included in the next edition.
Cheers!

Create a MOM System Incorporating SNMP and Non-SNMP
Network Elements
Problem
•
Need to monitor both SNMP and non-SNMP equipment.
•
Need to consolidate monitoring of legacy and modern networks.
•
Inherited mixed collection of mutually incompatible equipment from predecessors.
•
Inherited incompatible alarm systems from merger/acquisition of another company.
Solution
T/Mon NOC consolidates all your equipment, regardless of protocol or manufacturer, to one platform,
giving you a single-screen view of all your network equipment. T/Mon NOC supports over 20 different
protocols, including SNMP, TL1, TABS, TBOS and many proprietary protocols. (For a full list, see
Appendix).
Because of its support for multiple protocols, T/Mon NOC can monitor hundreds of different devices. For
every protocol it supports, T/Mon NOC supports every device that uses that protocol — and you’re not
charged extra probe fees for supporting multiple devices.
It doesn’t matter what the size of your integration issue is. Whether you have a few incompatible systems, or you need to consolidate two entirely separate networks, T/Mon NOC will give you a seamless
view of all your equipment.

Fig. 2. T/Mon NOC can act as a local NOC that collects alarms from local remote sites and mediate all alarms to
SNMP traps that are forwarded to the SNMP manager at the regional NOC.
Create a Local NOC for Local Visibility Within an SNMP Network
Problem
•
Relying on a distant regional NOC for alarm notifications gives you limited visibility and prevents
timely repairs of remote site problems — ultimately increasing downtime and maintenance costs.
Solution
T/Mon NOC can serve as both an alarm collector and alarm forwarder. Alarms within your local area can
be collected to your T/Mon NOC using any of T/Mon’s supported input protocols. You have real-time
visibility of all your equipment, giving you the power to proactively monitor your remote sites and correct problems early.
While collecting alarms at the local level, the T/Mon NOC will simultaneously forward your alarms in
SNMP (or in TL1, ASCII, TABS, TBOS or other output protocols) to your central regional NOC. From
the regional NOC’s point of view, it’s no different than if the local alarms had been sent directly.
Another advantage of this setup is that you can selectively filter which alarms will be forwarded to the
regional NOC. You can have an alarm for everything you need to see locally, down to very granular
detail, without overwhelming the regional NOC with a cascade of alarms.
5
Mediate Non-SNMP Alarms to SNMP
Problem
•
Need to monitor non-SNMP equipment from your SNMP manager.
Solution
T/Mon NOC’s alarm collecting and alarm forwarding capabilities combine to create a protocol mediation solution. T/Mon collects the alarms in their original protocol, mediates them to SNMP traps, and forwards the traps to your SNMP manager.
Any alarm that T/Mon collects can be mediated to an SNMP trap. Once again, you can filter which alarms
T/Mon forwards, so you only see the alarms you want to see.

Mediate SNMP Alarms to TL1
Problem
•
Need to monitor SNMP equipment from your TL1 manager.
Solution
T/Mon NOC can also mediate alarms to any of its supported output protocols, including TL1. T/Mon
NOC will collect alarms from SNMP devices or any other supported equipment and mediate the alarm
inputs to TL1 autonomous messages, forwarded to your TL1 manager.

Fig. 4. T/Mon NOC gives you many ways to filter unimportant alarms.
•
Alarm system reports every unimportant status alarm, conditioning users to ignore alarms.
Solution
T/Mon NOC offers several features to filter nuisance alarms:
Alarm Qualification: if problems are self-correcting, you might not need to know about them. You can
filter these alarms by using an alarm qualification time that sets how long the alarm condition must be in
effect before an alarm is declared.
Alarm Silencing: alarms that oscillate and create a lot of alarm activity can be silenced for a specified
length of time.
Alarm Tagging: oscillating alarms can also be tagged to stay silent until untagged.
No Log: alarms that are simply not important do not even need to appear on the monitoring screen. The
alarm report goes straight to the history file, where it is recorded and can be retrieved later for analysis,
if necessary.

All Alarm
Data via SNMP
SNMP Manager
Fig.5. The NetMediator mediates TBOS alarms to SNMP traps on-site.
•
Need to monitor on-site TBOS equipment (such as microwave radios) from your SNMP manager.
Solution
The NetMediator T2S provides dedicated on-site protocol mediation of TBOS devices. The NetMediator
mediates up to 8 displays of TBOS data to SNMP traps. Mediating TBOS to SNMP gives you much better visibility than the alternative, relying on vague, major/minor summary alarms. The TBOS data contains detailed alarm descriptions, allowing you to diagnose equipment problems accurately.
The NetMediator is also an SNMP RTU with 32 discrete alarms, 8 analog alarms and 8 control relays.
Mediate Contact Closures Collected at Your Main Distribution
Frame to SNMP
Problem
•
Collecting contact closure alarms from a main distribution frame ordinarily requires hours of
tedious cross-connecting between a terminal block and an SNMP remote telemetry unit.
Solution
The Remote Alarm Block 176N combines the functions of a terminal block and an SNMP RTU, providing easy conversion of contact closures to SNMP traps right at your main distribution frame. The RAB
is a compact alarm block that mounts directly to your MDF, or to the wall if space is at a premium. The
wires at the distribution frame are connected directly to the
Remote Alarm Block’s wire-wrap terminals — and the only thing
that comes out is one Ethernet cable that connects directly to your
LAN and your SNMP manager.

ity alarms, temperature sensors and environmental alarms, etc.) from your SNMP manager.
Fig. 7. The NetGuardian 832A mediates discrete and analog alarms from remote site infrastructure equipment to
SNMP traps.
Solution
The NetGuardian 832A remote telemetry unit mediates standard alarm in like contact closures and analog voltages to SNMP traps. All NetGuardian inputs can be mediated to SNMP traps — but you can select
to not send a trap for each individual alarm, so you can filter out any unimportant stuff.
The analog inputs send traps for four thresholds, plus the SNMP manager can retrieve live actual readings from analog inputs by issuing a GET command. SET commands issued to the NetGuardian will activate the control relays, for turning on-site equipment on and off, locking and unlocking doors, etc.
The NetGuardian can report to up to three SNMP managers at different IP addresses simultaneously,
which makes it great for filtering alarms to different departments. The NetGuardian can also report simultaneously to T/Mon NOC.

Fig. 8. The NetGuardian will transport SNMP traps over dial-up or serial connection to a PPP server that interfaces with your LAN and SNMP manager.
Solution
The standard NetGuardian 832A comes with an internal dial-up modem for backup transport. The
NetGuardian is also available with optional support for RS-232, RS-422/485, 202 modem, 212 modem,
FSK modem or PSK modem.
The NetGuardian can transmit SNMP traps over dial-up or supported serial transport to a PPP server,
which in turn connects via LAN to your SNMP manager.
The NetGuardian also provides a migration path for converting sites to LAN transport. Installing a
NetGuardian now will provide immediate SNMP support over existing transport; when LAN access is
installed at the site, you only have to switch the NetGuardian to LAN transport — and you don’t have to
install a new RTU. You can either turn down to dial-up or serial connection or keep it as a secondary
backup data path.
Ping IP Elements and Receive SNMP Traps if a Device Fails or
Goes Offline
Problem
•
Need to monitor online status of IP elements from your SNMP manager.
Solution
Both T/Mon NOC and the NetGuardian 832A have ping alarm functionality. Either unit will ping IP elements and send an SNMP trap to your SNMP manager if a network element does not respond to the ping.
Which unit you should choose for this application depends on the scale of your needs. The NetGuardian
can ping up to 32 IP addresses; T/Mon NOC can ping up to 960 IP addresses.

Need 24/7 monitoring, but you can’t afford a 24/7 manned NOC
Solution
T/Mon NOC comes standard with everything you need for 24-hour pager and email notification. Paging
and email take network alarm monitoring out of the NOC to wherever you are — your car, your remote
sites, and even your home.
You’ll have total assurance that you’ll be notified if problems happen at any time. You can keep your field
techs out in the field, dramatically reducing windshield time. Email notifications even create an automatic alarm history record.
Alarms can be acknowledged or tagged by two-way paging or email from your cell phone. T/Mon NOC’s
automatic escalation ensures that you’ll be notified if a tech doesn’t acknowledge a page.
The NetGuardian 832A also supports pager and email notifications — perfect for monitoring small networks without investing a lot of manpower.
Install Cost-Effective SNMP Monitoring for Small and Large Sites
Problem
•
One-size-fits-all RTUs don’t scale to the needs of large or small sites, leaving you with the options
of paying for more alarm capacity than you need, installing insufficient alarm capacity or buying
multiple units to cover one site..
Solution
The NetGuardian 832A, NetGuardian 216 and NetGuardian 480 provide SNMP RTU capabilities, scaled
to the needs of small, medium and large sites.
11
The NetGuardian 832A provides 32 discrete alarms, 32 ping alarms, 8 analog alarms, 8 control relays,
and 8 serial reach-through ports. A powerful all-purpose RTU, the NetGuardian 832A has all the tools
you need to manage your remote site. For extra-large alarm capacity, the NetGuardian 832A can be
augmented with 1–3 NetGuardian Expansion units, which raise the NetGuardian’s alarm capacity to 80,
128 or 176 discrete alarm points.
The NetGuardian 216 provides 16 discrete alarms, 2 analog alarms, 2 controls, and 1 serial reachthrough port. The NetGuardian 216 provides cost-effective alarm monitoring for small sites such as
remote huts, collocation racks or enclosed cabinets. With the NetGuardian 216, you can afford to deploy
alarm monitoring at every site in your network.
The NetGuardian 480 provides 80 discrete alarms and 4 controls. The NetGuardian 480 offers enough
alarm capacity to cover an entire site, saving you the cost of buying multiple units and giving you the
most economical cost per alarm point.

Remote Alarm Block 176N
Convert Contact Closures to SNMP Traps
Right at Your MDF
Ordinarily, if you want to get SNMP Traps from your Main Distribution Frame, you’re looking at hours of work and a hefty
price in technicians’ time and overtime pay.
First you’ve got to collect all the wires at your Main Distribution Frame and tie them down to a terminal block. Then you’ve
got to cross connect the wires from the terminal block to an SNMP RTU — and that means running the wires over an equipment ladder and sewing them down.
There’s an easier way - the Remote Alarm Block 176N. It’s a remote alarm block and SNMP RTU in one unit. The RAB
installs right in your Main Distribution Frame. Tie all the wires to the RAB — and the only thing you’ve got going out is
a nice, clean Ethernet cable … straight to your LAN and your SNMP manager.

NetGuardian 480
The low-cost, easy-to-implement solution to monitoring
your entire site with just one unit — for SNMP or TL1
The NetGuardian 480 (NG 480) is a specialized member of the NetGuardian family, optimized for use as a high-capacity
discrete-only responder. The result is a highly cost-effective solution for gathering the diverse equipment at your remote
site and integrating it into a single modern network management system.
With 80 discrete alarm inputs — 2½ times as many as the NetGuardian 832A- you can easily forward all the alarms of a
small to medium-sized site. This dense alarm coverage gives you the convenience of a single-box solution, saves you the
cost of buying multiple low-capacity RTUs, and offers you the lowest possible cost per point.
