OpenScape Cordless IP V2 is the DECT over IP solution for pure and hybrid Unify IP platforms.

The radio technology used in the OpenScape Cordless IP V2 solution complies with the DECT (Digital Enhanced Cordless Telecommunications) standard. The OpenScape Cordless IP V2 solution makes the DECT standard already established for mobile voice communications also available in Voice over IP infrastructures. The entire radio range managed by the system consists of DECT IP base stations that either together form a seamless network of overlapping and synchronous radio cells or individual islands of radio signals. The size of a radio cell depends on local conditions. The connection to the Voice over IP infrastructure is made by means of the SIP protocol. This means that DECT radio cells are the perfect way to supplement SIP-capable Voice over IP systems as mobile communication solutions. DECT IP base stations support the seamless handover of existing voice connections, in other words the changeover between the radio cell and a DECT handset during a call. In addition, the roaming function is made available to mobile users, i.e. the change of radio system without an existing call.

Solution Components

The OpenScape Cordless IP V2 system solution consists of the following main components:

• Handset: DECT handsets with PN-CAP functionality
• Base station: DECT IP base station with PN-CAP/GAP functionality for the DECT handsets and IP interface with the Ethernet network
• OpenScape Cordless IP V2 software (DECT Manager and Integrator) is the central software component for:
  • controlling the DECT IP base stations
  • implementing the SIP/RTP interfaces in the direction of the Communication Server
  • central administration and configuration of the entire OpenScape Cordless IP V2 solution

The DECT Manager SW can run either on an active DECT IP base station (small solution) or on a DECT IP base station with deactivated DECT part (medium Solution).

The Integrator SW runs either together with the DECT Manager on a base station (small and medium solution) or separate on a virtual server (large solution)

Overview

This section gives you an overview over the most important features of OpenScape Cordless IP V2.

DECT IP base station (BSIP2)

DECT IP base stations form a network of radio cells and conduct communications with the handsets. If these radio cells overlap and are synchronized, the DECT handsets can move between the radio cells with an existing voice connection. The best location for the DECT IP base stations for radio coverage in a building or site is determined by means of radio measurement. Special antennae can be used for increased radio ranges. The DECT IP base stations can be fitted with an outdoor casing to protect against inclement weather. DECT IP base stations have the complete software for DECT and IP functionality. This software does not need to be configured and administered locally on the DECT IP base stations; this can be conveniently implemented on a centralized basis by means of the OpenScape Cordless IP V2 software.

OpenScape Cordless IP V2 Software (DECT Manager and Integrator)

The DECT Manager software has several functions, exists once (small and medium solution) or multiple times (large solution) in the system and can be activated on one of the DECT IP base stations. Function: Router and protocol converter The DECT Manager software is the interface between the IP DECT base stations on the one hand and the Communication Server on the other. It has a router and protocol converter function whereby it controls the voice connections between the Communication Server and the relevant DECT IP base station and also converts these into a data format that can be used by the DECT base stations. Only the DECT Manager knows the DECT IP base stations with which the relevant handsets are associated; this is not apparent to the Communication Server. The DECT Manager software is a Gateway User agent for the Communication Server which manages the configured handsets. The DECT Manager software is also used to register all handsets on the Communication Server; this software administers the login procedure and the active DECT handsets. The Integrator SW exists only once in the system and runs in small and medium solution together with the DECT Manager on one of the DECT IP base stations, in the large solution on a virtual server under VMWare. Function: Configuration and administration interface All administration and configuration of DECT IP base stations and OpenScape Cordless IP V2 software itself is executed by means of the web-based management of Integrator software. Function: Synchronization management In DECT systems with a circuit-switched connection, e.g. OpenScape Cordless Enterprise/Office systems, the synchronization information required to synchronize the base stations is derived from the UP0 connection. This is not possible in the case of the OpenScape Cordless IP V2system. However, accurate time synchronization between the DECT IP base stations is vital for a seamless call handover. A seamless handover cluster is formed between synchronous DECT IP base stations; calls can only be handed over seamlessly in this cluster. More clusters of this type are possible for each Communication Server, however these are not synchronized with each other. Seamless handover is not possible between different non-synchronous clusters. Synchronization via DECT (radio synchronization) In order to synchronize with another DECT IP base station via the DECT interface, a DECT IP base station must be within the overlap area of the radio cell that forms this DECT IP base station. In addition, the DECT IP base station can be synchronized on other DECT IP base stations, which increases the availability of synchronicity in this cluster. In the event that synchronicity is lost, this DECT IP base station no longer accepts calls. After all ongoing calls on the asynchronous DECT IP base station have been ended, an attempt is made to resynchronize this DECT IP base station. Only then can new calls be made on this DECT IP base station.
