Manage digital transmission networks

Welcome to SGRwin a multi-vendor and multi-technology Network Management System for Utilities

Discover SGRwin a powerful NMS

Utilities use dedicated (private) telecommunication networks to guarantee the continuity on the delivery of the service provided. Those networks are thus critical networks.

Utilities have very long life cycles for their dedicated networks, often more than 25 years. These networks are composed of equipment from different manufacturers and technologies, with different levels of maturity. Life cycles in telecom equipment manufacturers are shorter, around 10 years, and portfolios are impacted by mergers and acquisitions. This is a huge problem for Utilities who have to manage their networks for a much longer time while planning the next technological evolution.

SGRwin is a Network Management System (NMS) that allows to manage equipment from different manufacturers and technologies and provide a unified vision of the network. The list of managed equipment is large, including legacy and modern equipment, a reflection of the typical Utility network.

SGRwin replaces legacy discontinued network management systems, providing legacy networks with enhanced functionalities, while integrating as well modern equipment, allowing the smooth transition of services from legacy to new ones. SGRwin enables a smooth transition from TDM networks to next generation packet based networks.

Others, traditional network monitoring systems,  only list alarm flows and leave up to the operator to understand the real impact in the service.

SGRwin provides business information through advanced functionalities that allow to know how a service is performing and what is the impact of a failure on the service.



Fault Management

Fault management

Fault management is the chain of activities performed in order to monitor the network, detect failures and take the corrective measures to solve or mitigate the failure. Network management systems are the cornerstones for fault management. SNMP monitoring and Q1 monitoring are available under SGRwin.

Why is multi-vendor/technology important?

Networks are composed of equipment from different manufacturers and technologies. Usually, a failure in the network involves or impacts to different equipment. Multi-vendor/technology NMS provides a consolidated view of the complete network in one system making easier to trace the root cause of the failure instead of checking the partial view provided by vendor specific NMS.

NMS Fault Management

SGRwin provides multivendor/ technology fault management in a consolidated alarm view. In addition, more than one alarm viewer can be opened simultaneously in the same workstation and have their own alarm filters applied allowing different alarm views.

  •  Multi-vendor and Multi-technology network topology maps with a custom background
  •  Multiple simultaneous alarm monitoring windows in the same workstation
  •  Alarms at the equipment level, circuit level, service level
  •  Circuits affected by an alarm
  •  Configurable alarms in colour, severity, text
  •  Alarm filtering, acknowledge, suppression
  •  Equipment Local Craft Terminal launch from alarm record
  •  Equipment location from alarm record.
  •  Event forwarding by email
  •  Reports



Configuration consists of setting the desired values in the network equipment parameters in order to create the network or obtain certain service / behaviour from it.

SGRwin configures the equipment either in native modes, like Dynanet and Connection Master case,  launching the local craft terminal (LCT) or both.

SNMP protocol VS Q1 protocol

Protocols define a language and connectivity rules to access the equipment resources and configure them. Nokia designed Q1 protocol to communicate with the Dynanet equipment family. This protocol works over DCNs composed by serial data links.

SNMP or Simple Network Management Protocol is one of the most widely used protocols to communicate with equipment. This protocol works over IP DCNs. Is defined by several IEFT RFCs and implemented by many vendors.

SGRwin allows to create end to end (E2E) circuits according to critical requirements: protected circuits, circuits using different infrastructure, logical linkage of circuits that provide service redundancy.

With SGRwin multivendor circuits  can be created just selecting the end points. The system automatically calculates the available paths and operator selects the most suitable one.

To create multivendor circuits SGRwin creates the required cross-connections in the supported equipment and uses virtual nodes to load cross-connection tables  for other manufacturers. It means that SGRwin can  import  third party NMS circuit reports and use this information in the multivendor circuit creation.

SGRwin provides Unmanaged elements (UME)  to create complete network maps. UME are nodes and links, not supervised by the system, and are used to provide visual information of elements that are connected to the network or around it.

SGRwin features are:

  • Automatic equipment structure building
  • Vendor Local Craft Terminal launch
  • Web based manager launch
  • Tools (Telnet, SSH, Ping)
  • Scheduled backup/restore of equipment settings
  • End to End (E2E) circuit configuration and display.
  • Protected circuit creation avoiding to use the same infrastructure.
  • Simultaneous display of redundant circuits
  • Link free capacity and slot usage
  • Support of virtual nodes and unmanaged equipment (UME)
  • Third party NMS reports circuit import.

NMS Configuration


Network administration

Administrate a network includes all the activities related to the network inventory and its maintenance. Inventory includes all the hardware infrastructure and the business logic created on top of it such customers, sites, services, circuits…

Why are inventory reports important?

The inventory contains all the information configured and all the equipment present in the network.
It is critical to be able to search, filter, display, and export this information to get relevant business information.

NMS Administation

SGRwin provides a complete and comprehensive network inventory, including sites, equipment in sites, cards in equipment, serial numbers, SW versión, links between sites, circuits, services….

  • Multi-vendor inventory
  • Serial number inventory
  • Link advanced info, duck, segments, frame
  • Multidimensional inventory reports
  • Scheduled database back-up and restore



Performance monitoring

Performance monitoring aims to measure the quality of the service given by an equipment or the quality of a network service. A network service is given by one or several network equipment.

Performance monitoring measures the desired network element (equipment or service) according to certain parameters such as Error seconds, Unavailability seconds, Error rate among others.

Why is performance monitoring so important?

Performance monitoring provides a view of how a service is perceived by the customer.

While alarm monitoring provides information on how the network is behaving at the certain moment, performance gives information of the behaviour of the network in the time.

NMS Performance

SGRwin implements multivendor network performance management. Performance information for different equipment like PDH and SDH nodes, microwave radios, teleprotection and more is available and stored. Performance data can be exported in the most common formats.

  • SONET monitoring according to G.826
  • Configurable performance management
    • Equipment to be monitored
    • Counters to be stored
    • Start/ End date/ period of storage
    • Status
  • Circuit performance. Performance not far an individual equipment but for the end to end circuit.
  • Graphical view or performance reports


Utilities’ dedicated networks ensure the delivery of critical services to the society. This is the reason why those networks must be dedicated to that specific service and must be secure.

Secure the access to the network resources is of paramount importance. Users must be granted the required access level to the resources and user activity must be tracked and registered.

Security is of paramount importance in critical networks.

NMS Security

SGRwin uses up to date operating systems according to IT compliance rules. Different methods of user authentication are supported. Every user can be granted rights (individual, roles and groups) that shapes the access to the network.

  • Cyphered  client-Server communication
  • Secure access control
  • User authentication via Radius, Active Directory…
  • User privileges limited/grouped by permissions, roles and groups.
  • Permissions per equipment type and views
  • Automatic client log-out
  • Events and activity logs
  • SNMP v1,2 and 3 supported


Fieldwork is any task performed on-site by the field force. It means that an authorized person has to visit the site where the equipment is physically located and perform the required task. Typical field force tasks are: Preventive maintenance, Corrective maintenance and Inventory.

Timely response to critical alarms is essential.

As a result of the fault monitoring activity, it might be decided that a visit to the site is needed in order to fix a problem pointed by a critical alarm.


SGRwin incorporates an interface with CIC field force management tool, FIELDEAS to link network alarms with field force activation.

SGRwin can automatically create a work order for the field force as a response of a critical event in the network SGRwin also allows the network operator to manually create a work order by right-clicking in the critical alarm and select the appropriate option in the menu.

An order is immediately managed by the work order tool according to predefined criteria avoiding in this way unnecessary delays.

Performance Monitoring VS Performance Management

Performance monitoring consists of displaying the performance key indicators in periods of 15 minutes and 24 hours typically.

Performance management also provides long-term storage and correlation of indicators to calculate new performance indicators and provide complex graphical representation.

Your business is not a network element but a series of critical services delivered by means of circuits created through several network elements.

In dedicated networks to measure how the circuits are performing is of paramount importance to understand the quality of service delivered.

Traditional performance provides a view of how an individual network element is performing but this is not enough to understand how a circuit is performing.

SGRwin correlates E2E and inventory information to understand how circuits are performing.

Predefined dashboards provide a comprehensive view of the critical information of your network.

Information Management

Business Intelligence (BI)

In general business intelligence aims to collect all the data spread in the organization to aggregate and correlate them in order to transform data into information.

This information increases the knowledge of the organization and improves the decision-making processes.

Information is usually spread through the system databases. SGRwin implements tools to get the most from the network data.

SGRwin includes a business intelligence tool for data analysis and custom reports creation.

Complex reports and graphics can be implemented giving multidimensional business information.

 Network Evolution

TDM networks VS Packet networks

Time division multiplexing (TDM) networks are and have been present in critical infrastructures since many years ago. PDH and SDH equipment provides reliable and secure communications and switching time below 50ms (critical for power utilities).

But new services and devices demanding efficient bandwidth usage and improved connectivity are gaining room in critical networks. Packet networks fulfil those requirements at a lower cost.

Still, the shift from TDM networks to packet networks is happening at a slow pace.

Utilities networks are facing a transformation from traditional TDM technologies towards packet transport technologies.

This transformation must be smooth and seamless in order to preserve the critical services. SGRwin combines in the same system your existing network with packet networks (Carrier Ethernet and soon MPLS-TP). Migration from existing network to packet network will be performed under the same SGRwin system in a controlled way and thus minimize the risks.

The operating systems in which SGRwin is implemented include the remote access options (RAS, ADSL, etc) among their network options, which allow the TCP/IP network to be extended through the telephone connection, allowing client applications to be located beyond the bounds of the LAN. For example, some users of SGRwin can use this method to monitor and operate the network remotely, from home, in the event of an emergency.
