Farm Food Case Study

Farmfoods retail chain installs 3G failover system to guarantee EPOS uptime

Major food retailer rolls out Billion 3G/ADSL failover routers to its 300+ outlets

Frozen food specialist, Farmfoods, has over 300 retail outlets across Britain.  As with all retailers, Farmfoods aims to ensure customer card payments made through the EPOS system are authorized as quickly as possible; this enhances the customer experience, maintains the reputation of the business and increases staff productivity.

One major threat to ensuring a seamless payment process is a break in the telecommunication line between the store and the bank. To address this threat, Dacoll Ltd,

IT consultant to Farmfoods, recommended a specific Billion 3G-failover product that would guarantee a consistent and secure working EPOS system even if the fixed line communications went down. The solution also needed to be able to cope with dynamic IPs, on both ADSL and 3G networks, across different geographic locations with varying signal strength.

The Billion BiPAC 7800GZ was chosen to be installed as a trial run for 30 retail outlets over a six month period - during which time the units proved themselves on several occasions when ADSL failed.  After a successful installation and review of the trial, Dacoll has rolled out this solution to all of Farmfoods’ 300+ stores across the UK. Each outlet’s EPOS system can now be assured of: data security; automatic failover to 3G and back again; instant communication to Farmfoods HQ of failover activation via email alerts

The 3G failover system also ensures each outlet can still communicate via email if the fixed line infrastructure fails. Mark Haggerty, IT Manager at Farmfoods explains: “The Billion BiPAC 7800GZ provides Farmfoods with a simple 3G backup to DSL communications. It is vital our stores maintain IP connections for processing payments, but it is also important to be able to send orders and keep in touch by email; if a problem arises, we need a router that reacts without user intervention – the Billion units fulfil this requirement, leaving our staff to concentrate on delivering the best service to our customers.”

In the past, Farmfoods kept a small stock of 3G routers at HQ that could be deployed for prolonged outage; however these took time to be delivered to the affected store, required manual setup and were also comparatively expensive. The new system means each individual outlet is equipped and ready to handle any ADSL failure 24/7 cost-effectively, with no user intervention.

Farmfoods uses three different mobile networks, with the network provider with the best coverage selected for each location. All outlets use Dynamic IP on the SIM with ADSL as the fixed line infrastructure.

The failover system provides peace of mind both to outlet staff and HQ. Edward Kung, MD at Billion UK, explains: “We’re delighted to have worked with Farmfoods and Dacoll on this extensive project. The BiPAC 7800GZ is perfect for retail chains to ensure card payment systems’ uptime whether using ADSL or 3G – staff can rely on them 24/7. It is very flexible, able to cope with different mobile networks and fixed infrastructure, challenging geography and fixed or dynamic IP”

UPDATE 2017: Farm Foods are still using the original 7800GZ in existing stores which was deployed in 2012, but for new store installations they have upgraded to the 7820NZ model which adds dual SIM functionality, and the 8920NZ model which has dual SIM and an integrated VDSL modem.

Key Features of Billion BiPAC 7800GZ

Always-On Connection

The BiPAC 7800GZ features triple-WAN interface allowing users to connect to the Internet via either wired connectivity of ADSL, or broadband connectivity, such as cable or BT Infinity (FTTC) by configuring one of the Ethernet ports as a secondary WAN, or via 3G connections via inserting a 3G / HSPA SIM card into its built-in SIM slot. The auto fail-over feature ensures maximum connectivity and minimum interruption by quickly and smoothly connecting to a 3G network in the event that the ADSL line fails. The BiPAC 7800GZ will then automatically reconnect to the ADSL connection when it’s restored, minimizing connection costs. These features are ideal for retail and office situations where constant connection is paramount.


The Billion BiPAC 7800GZ is tried and tested in the field -proven to be a robust, flexible and easily user-configured unit. It uses high tech components, including the top of the range Broadcom ADSL chip and Sierra Wireless 3G embedded module. Not only can it send email alerts if a failover occurs, but also alerts of 3G data usage figures. In addition, the embedded 3G module provides a more robust design, instead of external dongle attachments which have been known to become knocked, broken or missing.

High security

The BiPAC 7800GZ supports embedded IPSec VPN (Virtual Private Network) protocols, allowing users to establish encrypted private connections of up to 4 simultaneous tunnels over the Internet. With a built-in DES/3DES VPN accelerator, the router enhances IPSec VPN performance significantly - so users can access a card payment system or corporate intranet and transmit sensitive data between branch offices and remote sites anytime, thus enhancing productivity.
