TDM NIS

TDM's railway communications platform for operations, routing calls, text messages and alarms to the right operator at whichever terminal they log in.

Overview

Call handling for Help Point estates

The TDM Network Information System (NIS) is TDM’s operational communications platform, delivered, configured, upgraded and supported by TDM on the networks it serves.

Platform

One system for calls, messages and alarms

NIS is IP-based, so only one IP environment is needed. ComNodes provide call-server functionality, voice switching, call routing and system interconnection. Dedicated gateways connect it to existing PBX systems, private or public networks, ISDN and analogue telephony, and VoIP. Operator terminals combine GSM-R, analogue or digital radio and telephony in one device. Optional functions are assembled to each operator’s requirements, including analogue, TETRA and Tetrapol radio integration, connection to CCTV systems, Public Address announcements and call recording.

TDM NIS operational communicationsTDM Help Points, VICOS call points and, through gateways, existing PBX systems, telephony, VoIP and radio networks connect to TDM NIS, which routes calls, text messages and alarms by role to operator terminals. Each operator's roaming profile follows them to any terminal, and a central management tool configures the system.ConnectedPlatformControl centreTDM Help PointsPassenger callsVICOS call pointsRemote management with SNMPGatewaysPBX, telephony, VoIP and radioTDM NISCalls, messages and alarms by roleOperator terminalsRoaming profilesCentral managementConfiguration and softwareConnectedPlatformControl centreTDM Help PointsPassenger callsVICOS call pointsRemote management with SNMPGatewaysPBX, telephony, VoIP and radioTDM NISCalls, messages and alarms by roleOperator terminalsRoaming profilesCentral managementConfiguration and software

Roles and access

The right calls reach the right operator

Calls, text messages and alarms are routed by role, and roles can be shared in parallel when traffic is high. With a roaming profile, an operator logs in at any terminal on the network and gets their own interface, with their calls and alarms routed to it. Access rights can be limited by location and by function, for devices, people and groups.

In projects

Renewals, upgrades and control centre dispatching

In a network Help Point renewal, TDM configured and commissioned NIS alongside the physical rollout so that new units came into service with call handling in place. In a network-wide technology upgrade, TDM upgraded and configured NIS at Puddle Dock KICC, and careful phasing maintained Help Point availability during each system update. In a rail control centre, TDM delivered GSM-R and fixed telephony dispatching to controller workstations, integrated with the train describer system.

Features

Each node works on its own, with no central core

  • Central management of configuration, software distribution and users
  • Remote monitoring, configuration and updates of TDM's VICOS call point electronics, with SNMP diagnostics
  • Routing elements that can be set up with multiple redundancies
  • Each node works autonomously, with no central core for operative functions
  • A fully meshed network, with routing that adjusts automatically when a failure is detected
  • Modular, from a single site to a networked estate
