OpenScape Cordless IP upgrades IP communications systems by a campus-wide mobility solution.<\/em><\/p>\n\n\n\n Mobility<\/p>\n\n\n\n Providing staff with cordless phones allows for direct, location-independent communication and is ideally suited for instant availability and enabling decisions to be taken quickly. This generates organizational and economic advantages.<\/p>\n\n\n\n The flexibility in the number of stations, station frequency, surface coverage, upgrading and the provision of comfort functions with the most modern handsets characterize the system architecture of OpenScape Cordless IP<\/a>.<\/p>\n\n\n\n The digital transmission standard DECT (Digital Enhanced Cordless Telecommunication) is used worldwide and works in a secured frequency range.<\/p>\n\n\n\n The OpenScape Cordless IP<\/a> solution also makes the established DECT standard available in Voice over IP infrastructures. SIP (Session Initiation Protocol) is used to connect to the communication systems. This enables DECT cells to optimally complete SIP-enabled Voice over IP systems as the basis for mobile communication solutions.<\/p>\n\n\n\n Multi-cell technology<\/p>\n\n\n\n The radio coverage required in the building or on company grounds is achieved by means of multi-cell technology. The synchronized cells of the base stations installed at the company overlap, so that calls in the entire area of the cordless system can be seamlessly set up and made on the move (roaming and handover).<\/p>\n\n\n\n Handsets<\/p>\n\n\n\n A high degree of flexibility and mobility makes the Atos Unify OpenScape DECT Phone S6<\/a> and OpenScape DECT Phone SL6<\/a> handsets for office environments, and the OpenStage M3<\/a> handsets for industrial environments to favorites among the cordless telephones.<\/p>\n\n\n\n The handsets offer excellent digital speech quality, a high degree of immunity to eavesdropping, and a long range (up to 50 meters indoors and up to 300 meters outdoors).<\/p>\n\n\n\n As well as low investment and operating costs, the phone provides simple user prompting in connection with the mode-dependent menu keys. This enables optimal access to the large range of comfort features.<\/p>\n\n\n\n A further advantage is the access security in the entire OpenScape Cordless IP<\/a> system, where central registration of the handsets in the system restricts access by unauthorized cordless telephones.<\/p>\n\n\n\n The OpenScape Cordless IP<\/a> handsets allow calls to be made in the area covered by the network.<\/p>\n\n\n\n Handsets enable the most important SIP comfort features of the communications systems to be used on the move within the site.<\/p>\n\n\n\n Detailed information on the individual handsets can be found in the Page for “OpenScape DECT, Handsets<\/a>, Datasheet)”.<\/p>\n\n\n\n DECT IP base stations<\/p>\n\n\n\n The base stations form a network of wireless cells and manage communications with the handsets. The multi-cell technology enables subscribers to move between the wireless cells with their handsets during a call.<\/p>\n\n\n\n The software of the base station contains complete DECT and IP functionality. The software does not need to be configured and administered locally for each base station but instead can be conveniently operated centrally via the OpenScape Cordless IP<\/a> software.<\/p>\n\n\n\n The optimal location of the base stations for coverage of a building or of a site is determined by a radio analysis-technical measurement.<\/p>\n\n\n\n Special antennas can be used to increase the range.<\/p>\n\n\n\n The base stations can be encased to protect them from the weather.<\/p>\n\n\n\n OpenScape Cordless IP Software<\/p>\n\n\n\n The OpenScape Cordless IP<\/a> software provides the interface between base stations on the one hand and the communications systems on the other.<\/p>\n\n\n\n Router and protocol converter<\/p>\n\n\n\n The software offers the router and protocol converter functions by controlling the voice connections between the communications systems and the respective base station. It also converts these into a data format which the base stations can use.<\/p>\n\n\n\n Configuration and administration<\/p>\n\n\n\n The base stations and the OpenScape Cordless IP<\/a> software itself are all administered and configured using the web-based management of OpenScape Cordless IP<\/a> software.<\/p>\n\n\n\n Synchronization management<\/p>\n\n\n\n In DECT systems with line-switched connection, e.g. Atos Unify OpenScape Cordless Enterprise, the synchronization information is attained from the connection. This is not possible with the OpenScape Cordless IP<\/a> system.<\/p>\n\n\n\n Accurate time synchronization is also necessary between the base stations for an interruption-free call transfer.<\/p>\n\n\n\n Synchronization via DECT (synchronization over the air)<\/p>\n\n\n\n A DECT IP base station must be within the overlapping area of the cell which this DECT IP base station forms in order to synchronize with another DECT IP base station via the DECT interface.<\/p>\n\n\n\n Synchronization via LAN<\/p>\n\n\n\n With this type of synchronization, the DECT IP base stations can be synchronized via LAN. This is based on a method similar to IEEE1588.<\/p>\n\n\n\n
