In 2007 Avon Tyrrell downsized their London office and movedkey employees to the main centre in the New Forest. As part ofthis exercise, systems were standardised such that everyoneused a common email system, data was stored centrally withbackup and opportunities to reduce costs were identified.

The London office was to continue with five staff where thefinance software and mail server is hosted. Fifteen workers atthe Activity Centre would need access to these systems in theiroffice and from home. A decision was also made to use Voice-over-IP(VoIP) technology to reduce telephone call costs.

Unified systems that were common to all staffRemote access between offices and teleworkersValue-for-money so that charity funds deliver the best returnReduce monthly costs where possible.Security, Reliability and Performance.

“Once we understoodAvon Tyrrell's requirementsDrayTek was the obvious choice. Our previousexperience with them was very good and weknow them to provide robust products that do thejob and can be deployed easily ”.Steve Jones, Christchurch Computer Centre

CCC assisted Avon Tyrrell in implementing a fullyresilient, secure and flexible network basedaround DrayTek's Vigor 2950 and Vigor 2820load balancing routers.

At the New Forest office, a Vigor 2950 wasinstalled with two ADSL lines to handle the datacommunications requirements. The loadbalancing feature allows both lines to be used toprovide maximum performance and in the eventof line failure the alternate line takes overautomatically. A VPN (Virtual Private Networking)tunnel was used to create a secure connectionbetween the offices over the Internet.

For voice, a VoIP server (IPPBX) was installed atNew Forest which connects with a second Vigor2950, also with two load-balanced ADSL lines.This enables the charity to make free calls acrossthe internet to the London office and home userswhich has resulted in a saving in excess of £200per month on telephone calls as well as saving ofcost of additional line rental.

In the London office and teleworker’s homes, aVigor2820 provided the ADSL/VPN connectivityand load-balancing/failover for the London office.

Avon Tyrrell - Network Topology (Simplified)

Avon Tyrrell’s headquarters in the New Forest uses ADSL for its voice and data traffic. Voice calls, incoming andoutgoing use Voice-over-IP using an IP-PBX on-ste. The IP-PBX and the IP Telephones use one Vigor 2950Router/Firewall for their Internet access. That Vigor2950 uses a pair of ADSL line in order to allow for failover in theevent of oneADSL line failing;ADSLcan be unreliable in remote locations such as theirs. Asecond Vigor 2950, withanother pair of Vigor 120ADSLmodems andADSL lines is used exclusively for their data requirements (web access,email etc.), again with the second ADSL modem and line providing contingency in the event of the first line failing.The remote office in London also has a pair ofADSL lines for failover and two telephones which act as extensions offthe main PBX in the New Forest. Teleworkers have a similar setup, with singleADSLor cable-modem lines.
