Intelligent Network Restoral System (INRS)

Intelligent Switching makes the right connections... automatically.

INRS combines monitoring, datascoping and switching functions to ensure that data moves continuously to its intended destination.

Backup for critical equipment and circuits
The INRS (Intelligent Network Restoral System) is an integrated network management tool for centralized real-time alarm reporting, diagnostic support and intelligent network restoral.

Most networks, particularly those that are transaction oriented, cannot afford service interruptions. With this in mind, INRS was designed to monitor, control and provide critical backup for network links or equipment. Typically attached to communication equipment at hub locations, the INRS enables the network manager to remotely detect problems and instantly restore service from his PC. Often, this occurs without end-user knowledge of failure conditions!

Configurable Switching
INRS link and equipment restoral can be set for automatic, controlled or manual switching. Typically, concentration points use INRS automatic switching to minimize downtime. However, network managers occasionally require controlled switching for less critical links or manual switching to dedicate links to their primary or secondary ports.

Automatic switching triggered by user-defined conditions
INRS continuously monitors remote links for user-defined alarm conditions. Audible alarms and link identification error messages alert the network manager of problem areas. With automatic switching enabled, INRS instantly restores the failed link or equipment to reestablish service. Automatic switching can also be scheduled for weekends or off-hours to satisfy routine outage period requirements.

Controlled switching regulated by the network manager
With INRS Controlled switching, the network manager can supervise the switchover of failed links or equipment. Group or Supergroup definitions enable single command control over individual or multiple link switching.

Manual switching provides override
With INRS manual switching the network manager can override automatic and controlled switching. By simply setting the appropriate front panel toggle switch, a common port can be dedicated to either the primary or secondary port.

Safety from unintended switching
INRS protects communications against accidental switching with two safely features. INRS Anti-Glitch Control Feature filters out electrical line noise which might trigger inadvertent switchover. INRS Delay Feature prevents switchover due to transient changes by requiring the new signal state to be stable for 1 to 64 seconds. In addition, INRS protects against power outages by maintaining all switch positions with latching relays.

Datascoping of remote links
Datascoping facilities at the control centre is a feature unique to Omicron`s product series. Without additional circuits or equipment, the network can view and analyze Rx and Tx data of remote links to determine protocol related faults.

Omicron`s modular architecture
Omicron`s wide range of data communication products is based on an innovative modular design. Reliable products can be mixed and matched in 19" racks. Up to 32 racks with 16 interface cards can be combined for a cost-effective, space-saving solution. The Omicron modular concept provides a migration path for network growth by building on investments already in place.

Easy to use operator interface
A menu driven interface supported by on-line help provides access to alarms, trends, utilisation, link status, etc. Refer to the SureNeT brochure for more information.

Omicron combines monitoring , datascoping and switching functions, that provide the network manager with a powerful fault isolation tool to minimize cost and maximize uptime.
