Robust, Flexible Design

There are many applications where devices and sensors can be connected to an RTU for the purposes of monitoring and remote control.  The many connectivity options available to the RTU make the RTU a robust, flexible tool for these applications.


RTU Applications

The RTU is capable of adapting to a variety of environments and applications.


Equipment Shelters

Equipment shelters include CEVs, mountain top equipment huts, transmitter huts, repeater stations, and fiber-route regeneration huts.


Headend management includes cable & HFC headends, digital TV equipment headends, nodes, and hubs.  When used in headends, RTUs provide an effective tool for monitoring gaps in mission critical equipment.

Many of the managed devices do not have embedded SNMP agents, though most have contact closure outputs that are activated during alarm conditions.  These outputs are connected to the RTU's contact closure inputs to allow these devices to be managed remotely.

Some of the managed devices already have embedded SNMP agents.  These devices usually still also have the external contact closure outputs.  In these cases the RTU provides uniform alarm management, with similar packets being transmitted regardless of the type of equipment being managed or is manufacturer.  The RTU provides an independent manager capability, while also incorporating environmental alarms and flexible connectivity options.

In this way the RTUs provide a consistent interface to a large variety of equipment from a number of manufacturers.  This simplifies training of operations staff, making it easier to identify the root cause of problems.  An RTU is a management gap filler providing additional levels of information for equipment which may have otherwise had little or no management capability.

Floor Alarms & Rack Equipment

Floor alarms cover a range of different things, but this description focuses on monitoring rooms full of rack based equipment and other general equipment.  The RTU provides a uniform alarm interface for monitoring racks of multi-vendor equipment, including security and environmental sensing.

Typical floor alarms are generated from a wide variety of equipment.

Kerbside / Roadside Cabinets

Kerbside cabinets are used by a number of different infrastructure industries including:



power, water, utiliteies, sewerage

road and rail traffic management

As these cabinets are located away from the central monitoring centers, it is critical that information and alarms are communicated quickly and efficiently.

The RTU can communicate back to the Operations Center using an Ethernet link or a dialup connection.  The RTU operates the same way in either case.  This means that if you deploy RTUs with different types of communication mechanisms, this is transparent to the staff at the Operations Center.

Server Rooms

Server rooms include IT equipment rooms, communications hubs.  PCs, servers, mini computers and mainframes.  Some or all of these will need monitoring.  These facilities usually incorporate adequate monitoring of network issues, storage, memory, and operating systems, but often fail to manage devices such as air conditioners, smoke alarms, high temperatures, water ingress etc.  When one of these alarm conditions arises, whole clusters of servers and other equipment can fail and can sometimes be irretrievably damaged.  RTUs can be used in server rooms to report back these alarm conditions in addition to normal operational feedback.

Exchange Equipment

Monitoring of exchange equipment is vital for the efficient running of any telco network.  Most core exchange equipment comes with its own monitoring capabilities, but often much of the supporting equipment is not monitored in a manner suitable for centralized monitoring control.

RTUs fill in these monitoring gaps, allowing central operations staff to monitor a range of equipment in real time using SNMP and web functionality.  RTUs provide a uniform interface over all connected equipment from one or more manufacturers.

Infrastructure Monitoring

Infrastructure includes CEVs, pipe lines, water, power nodes, sub station management, mountain top equipment huts, transmitter huts, repeater stations, fiber route regeneration huts, etc.

Items That Typically Need Monitoring

The following are items that tend to be monitored by RTUs in most applications.  Some applications may also need to monitor information more specific to those applications.

air conditioning

rectifier alarms

battery levels

mains power

water levels

pressure, flow rates, humidity

solar panel voltages and theft



site door control

water ingress

Midnight Technologies

Midnight Technologies designed the RTU and have organised all manufacturing.  Midnight Technologies now manage all sales and marketing activities for the RTU.(more)

RMS Has Moved

RMS has moved office. We are now co-located with our hardware designers as work gets under way on the next generation of RTU. (more)

New Firmware Released

The RTU now supports connections using CDMA mobile modems. It incorporates acknowledgement of notifications sent as SNMP traps or SMTP email messages, to ameliorate delivery of messages. The new firmware also allows connection to serial-based devices using the RTU's Multi Function Port and the new Pass Thru feature. (more)
