National Estate and Lettings agency
A national estate and lettings agency that have 40 offices through out the UK. The Head Office is in Bristol. Seetech staff have a long relationship with the customer having installed and maintained their old NT4 architecture, and recently migrated them to Windows 2000. In early 2001 they made a business decision to link all remote offices with HO. In the short term this will enable database integration and the use of Microsoft exchange 2000 at all sites. In the medium term they will move to deploy thin client technology.

After extensive consultation with Seetech and after investigating the cost of a private circuit solution, they chose a cutting edge solution using ADSL technology. This involves installing a 512KB ADSL line at each site with a Cisco router that will act as a firewall and VPN end point. At Head Office a 2MB leased line will be installed with a central Cisco PIX firewall, which acts as the "HUB" VPN end point for all the sites. Phase 1 of this implementation started in June 2002.

Leisure Management
A Leisure management company based in surrey manage sport centres nationally, currently approximately 70 centres. Their WAN architecture is based on a combination of frame relay and ISDN. All 70 sports centres link back to HO in surrey. There are also links between local centres in particular geographical areas. Overnight database replication occurs between the EPOS systems in each centre with the main SQL database held at HO. During the day the accounts staff in each centre manage the accounts through a central accounts system held at HO. They use Citrix thin client technology to achieve this. The links also enable the use of a central Email system, currently with approximately 1000 active users.

Regional Fire and Rescue Service
The F&RS wished to move from their ISDN based WAN to a fixed cost system as the expense of ISDN calls was becoming prohibitive. A tender was issued to link 24 sub-fire stations with HQ. Seetech staff won this tender with a solution based on channelized E1. An E1 presentation was installed at HQ with a 64Kb channel terminating in each of the 24 sub-fire stations. Ericsson routers were used at each site, with an Ericsson Amazon PRI router at HQ. With this solution the F&RS realised improved costs and as an additional benefit improved network speed and link reliably between the sub-fire stations and HQ. This has enabled the F&RS to move forward to implement Thin client technology at the sub-fire stations which will allow all servers, data and applications to be located and managed at HQ, substantially improving IT costs and control.
