System Description
teleCARE IP
3 System Structure
3.1 System infrastructure
The teleCARE IP system is part of the Ascom Communication Platform providing emergency call
services. The figure below shows the infrastructure around the teleCARE IP system.
Figure 2. teleCARE IP system infrastructure
In a typical configuration the infrastructure comprises the teleCARE IP system and one or more
messaging systems of the Ascom communications platform. The teleCARE IP carrier devices (NISM and
NIRC3) integrate with the other carrier devices through UNITE. All carrier devices require an
appropriate IP medium for carrying data, voice and messages.
teleCARE IP end user devices (doorside modules, bedside modules etc.) connect as active and passive
peripherals to the teleCARE IP room controllers (NIRC3).
In the teleCARE IP infrastructure the Unite Connectivity Manager (UNITE CM) module adds remote
management, system supervision, logging, fault handling, group handling, number planning,
message routing capabilities and other system services. The logged information can be viewed by
accessing the UNITE CM log viewer application.
The Messaging, Assignment, Reporting interface (MARi) web application is an enhancement to the
existing graphical user interface. It is designed to improve the efficiency of the caregivers’ work.
The teleCARE IP system requires a Dynamic Host Configuration Protocol (DHCP) server for the
assignment of IP addresses to the carrier devices.
For full details of the IP infrastructure requirements please refer to the “IP Infrastructure
Requirements” document TD 92636.
3.1.1 IP Medium
teleCARE IP requires a dedicated LAN network. The physical connection of NISM and NIRC3 is
Ethernet LAN using Cat-5 (or above) 10/100 Base-T or Unshielded Twisted Pair wiring (UTP).
