NetGuardian LT G2 Overview
1
Fig 1.1 Compact, easy-to-install, right-size capacity — the NetGuardian LT G2 ("Lite") offers a low-cost
way of effectively monitoring smaller sites.
Effective, easy-to-install, light-capacity alarm monitoring
The NetGuardian LT G2 is a compact, LAN-based, light-capacity remote telemetry unit. The NetGuardian LT G2
is designed for easy installation at smallremote sites, making it cost-effective to deploy alarm monitoring
throughout your entire telecom network.
Powerful monitoring for smaller sites
The NetGuardian LT G2 is based on the time-tested NetGuardian design used in high-capacity models. This telco-
grade remote is housed in a durable aluminum case that can be rack or wall-mounted. This SNMP remote is
scaled to the needs of small sites, such as remote huts, collocation racks, and enclosed cabinets - perfect for any
site where a large capacity RTU would be more than you need.
·Custom Voice Dial-In and Out with DTMF Acknowledge
·Data Dial-In and Out for TTYand T/Mon Alternate Path Reporting
·Up to 4 Discrete Alarm Inputs
·1 Integrated Temperature Sensor
·32 ping targets to monitor other devices
·1 Control Relay (Optional)
·Optional D-Wire Sensor Network
Easy Alerts via Phone or SNMP
When alarms occur, custom voice alerts will be sent to your phone. SNMP traps will also be sent to your SNMP
manager. Dial right into the NetGuardian LT G2 and request a verbal report using custom Voice Dial-Out
technology with DTMF acknowledge.
SNMP or T/Mon LNX
The NetGuardian LT G2 can report alarms to any SNMP manager or to the DPS Telecom T/Mon LNX Remote
Alarm Monitoring System using either SNMP or DCPx. The NetGuardian LT G2 can also report via SNMP and
DCPx.
Easy installation and configuration
Since it's LAN-based, the NetGuardian LT G2 installs quickly and easily, without the expense of laying dedicated
lines. The unit mounts in any 19" or 23" rack and occupies only 1 RU. The unit has spring-clamp terminal
connectors to make wiring alarms fast and easy. The front-panel LEDs show you the status for each alarm input
