With the new scalable Multi Cell AP500 base station for Small, Medium and Large Enterprises, we are opening a new chapter in professional and modern IP DECT technology. AP500 BENEFITS > Up to 254 basestations (4.000 for a project together with COMTEL) > Up to 1.000 handsets (16.000 for a project together with COMTEL) > DECT and LAN synchronisation > Over-the-air software updates for handsets > Repeater support > PoE support > TLS encryption > Wallmountable > Local and LDAP phone book support AP500 MULTI CELL IP DECT BASE STATION The new easy-to-use base station comes not only in a completely new design, but also with new, versatile functions. In addition to an integrated DECT manager, the AP500 also offers DECT and LAN synchronization. The integrated DECT manager manages all base stations in one installation and ensures constant availability and seamless handover. This means that calls are seamlessly transferred between the individual base stations – even across floors or buildings. Security is a top priority in daily business communication. With the integrated TLS encryption, the AP500 base station also sets absolute standards in terms of encryption. EXTREME SCALABILITY The new AP500 DECT base station provides a solid foundation for any installation size. From a small office with can enable individual installations comprising up to 254 base stations and up to 1.000 handsets. In a DECT project under guidance of COMTEL a system with 4.000 AP500 multi cell base stations and 16.000 handsets can be realised. Thanks to the AP500 base station, the maintenance of the devices can also be carried out easily and efficiently. Each base station can wirelessly send software updates to the connected handsets, greatly reducing the workload for the IT department. The system easily integrates towards a cloud solution that ensures easy maintenance and flexibility. comtelinternational.com IP DECT BASE STATION FOR SMALL, MEDIUM AND LARGE ENTERPRISES DECT MULTI CELL BASE STATION VOICE AP500

ON-SITE WIRELESS COMMUNICATIONS ON YOUR IP NETWORK COMBINING THE BENEFITS IP AND DECT TECHNOLOGIES DECT delivers on-site wireless telephony that uniquely combines the benefits of IP technology with the superior quality and facilities of the well-established DECT technology. A configuration typically consists of Base Stations (BSs), and DECT handsets. The BS connects to the IP network and form a DECT system that provi- des peer-to-peer IP communications. ADD SOPHISTICATED DECT WIRELESS COMMUNICATIONS TO YOUR NETWORK With VOICE DECT, a single converged network provides both fixed and wireless te- lephony. Wireless communications in a multi-site company or large campus environ- ment is a matter of installing Base Stations Points at remote locations, with no need for additional remote equipment. These remote locations become an integral part of your central communication infrastructure. Today’s business environment demands flexible ways of working and excellent customer services. Organizations seek to extend the reach of their converged voice and data network and integrate wireless communications without compromising on voice quality, availability and security. DECT realises all of this, and much more. WEB MANAGEMENT INTERFACE ROAMING AND SEAMLESS HANDOVER ENTERPRISE LAN DECT BASE STATION 3 DECT

WAY INTO THE FUTURE IP AND DECT TECHNOLOGIES Since its standardisation, DECT has developed into the most successful and favourite technology for wireless on-premises communications. Over the years many innovations have been introduced, resulting in the extensive feature set of VOICE DECT AP500 offered by Comtel. Today, IP DECT plays an important role in connecting and integrating devices, applications and data. It allows to dynamically design, manage and streamline meaningful workflows across an organization. Looking to the future, private 5G promises to become a viable option for organizations wanting to deploy their own mobile network without being dependent on a particular operator. 4 PROVEN RELIABILITY ACROSS ALL LEVELS DECT has been around for a while and still is the best possible mobility solution for practically all businesses. For one, it offers the ultimate in reliability - in terms of scalability, security and coverage. Its secure dedicated frequency band makes it totally free from interference, while encryption and security are standard. And once installed it never fails. CORPORATE DIRECTORY VOICE DECT provides users access to the company’s corporate directory. At all times the telephone numbers and names of the entire organization are at hand. No need to search for personal contact information or consult the nearest PC screen, just browse to the right person in your DECT handset. IP DECT INTEROPERABILITY SUPPORT THE SIP PROTOCOL VOICE DECT is an open system that can potentially interconnect with platforms from any vendor that supports the SIP protocol.

6 AP500 BASE STATION The VOICE AP500 DECT Base Stations provide extensive call features combined with crystal clear sound quality. VOICE DECT supports standard SIP and is optimised for the InFrom Voice communication platform. MULTI-SITE MOBILITY SOLID FOUNDATION FOR ANY INSTALLATION Consisting of a Dual Cell base station, a Multicell base station and a Repeater, the series is a solid foundation for any installation size. From a small office with only one base station up to large enter- prises and campuses with several hundred devices, the integrated DECT technology can enable individual installations comprising up to 254 base stations and up to 1.000 handsets. In a DECT project under guidance of COMTEL a system with 4.000 AP500 base stati- ons and 16.000 handsets can be realised. The AP500 Dual Cell Base Station is a perfect fit for small and medium-sized businesses, providing on-site mobility for users who must be contactable wherever they are within the office. Together with the VOICE G277, G577 and I766 DECT Handsets it offers an extremely cost effective and reliable DECT solution. The coverage can be extended with AP500 Repeaters if needed. The solution can also be upgraded to two AP500 Dual Cell Base Stati- ons in one system ensuring a larger coverage area. DECT

VOICE DECT IN ACTION IN THE OFFICE From small businesses to large enterprises, workforces are more mobile than ever in the past. With fewer spaces allo- cated to individuals, more flex-desking and a more distri- buted workforce, VOICE DECT provides the ideal solution for cost-effective and secure wireless connectivity across the office and its premises. VOICE DECT provides scalable and secure communications for single office, campus or even metropolitan environments. IN HEALTHCARE COMTEL’s IP DECT dramatically improves communication and collaboration in hospitals, enhancing the quality of patient care as well as patient safety, staff satisfaction and efficient clinical workflows. In care institutions, wireless communication between residents and mobile caregivers reassures residents and saves time. Caregivers can ascer- tain a call’s priority while on the go. CRUISE INDUSTRY A particular sector where COMTEL is favoured is the cruise industry. With everything shielded for radio signals, many small rooms, and everyone – guests and staff – expecting to be able to communicate as they walk around, a ship is an extremely difficult environment to deploy wireless commu- nications. IN RETAIL & WAREHOUSING Comtel’s smart retail solutions create deeper customer loyalty and accelerate better business results. VOICE DECT communications help to handle incoming callers with ease while attending to in-store customers. Store and ware- house managers have access to realtime data and order taking directly from the floor and can quickly respond to requests, reducing lead times and boosting productivity. 11 DECT IN HOSPITALITY VOICE DECT makes hotel staff reachable at all times, no matter where they are.
