Failover to Cellular

Enable always-on availability

Opengear Failover to Cellular™ (F2C) provides continued internet connectivity for remote LANs and equipment over high-speed 4G LTE or 3G networks when the primary link is unavailable. Ensuring speed to keep the network running smoothly and link diversity for true WAN resilience, Failover to Cellular is built on robust IP Passthrough technology. This allows for easy integration into existing installs or can be rapidly deployed for instant-on connectivity for new networks and branch locations.

This feature is useful for an SD-WAN deployment. SD-WAN enables organizations to reduce costs and maintain secure network connections, however the high bandwidth internet connections, routers and constant firmware updates associated with this can introduce a single point of failure. If the network goes down during a deployment, Smart OOB™ and Failover to Cellular ensures secondary access to the routers to easily reflash or power cycle. NetOps staff are able to remotely get the network backup and running without an onsite visit.

Increase resilience and remediation

Failover to Cellular allows organizations to maintain connectivity and decrease disruption with ensured business continuity. Easily integrating with existing IT systems and network infrastructure, F2C restores WAN connectivity without manual intervention. Utilized with Smart Out-of-Band  (Smart OOB), which is built into all Opengear devices, organizations are able to have remote access even when WAN and LAN networks are down. During an outage, in order to remediate the problem as quickly as possible, network engineers must have visibility of the whole network. Smart OOB provides engineers with full visibility to maximize uptime and reduce outages.


Remediate issues remotely

Distributed enterprises often times may experience disruption events that effect the primary network connection. Failover to Cellular built-in to Opengear devices, automatically activate a secondary connection to re-establish in and outbound network access. Once failover is enabled, Opengear devices are able to detect failures sending ICMP ping requests from the primary network interface to a primary and secondary probe address remotely. If these requests fail – the primary connection has been deemed as having also failed. When the primary connection has been restored, the devices automatically fail forward and resumes normal operation.



Swiss full service provider Quickline introduces new out-of-band management with failover to cellular backup for centralised management of IT infrastructures

The comprehensive service offered by Quickline Group, with its head office in Nidau in the canton of Berne, covers internet, telephony and digital TV through to digital workspace and business cloud hosting. So for Quickline, ensuring seamless network connectivity for business continuity was absolutely critical. The company has been using out-of-band management since 2008 for permanent monitoring and remote maintenance of critical IT infrastructures in its data centres and remote sites and ensuring high availability, even if the primary in-band network were to fail.

Because our networks are distributed all over the country, reliable remote access to critical infrastructure devices is essential for our support staff so we can act immediately and precisely and resolve possible faults remotely and as quickly as possible”, explains Simon Koch, Head of Network Operation, Quickline. “The quality of our customer service is of prime importance for us. That is why we have been using OOB technology for the last ten years across all of our business divisions. However, the time had come to replace our previous OOB solution, which only offered a conventional modem-failover connection, with a state-of-the-art solution.

Latest generation OOB solution with high-speed failover to cellular

As the second largest cable network provider in Switzerland we have a large number of sites scattered all over, even in the Alps. Since it’s difficult to get copper connections there, we were looking for an alternative which could also offer us an out-of-band management solution” Koch continues. “We looked at several manufacturers and finally decided on Opengear. The decisive factor was the integrated 4G solution for devices. Its functionality and the whole package with centralised software management met our needs exactly. That’s why we decided to replace our previous out-of-band management system generally with the new wireless OOB solution, with 12 or 48 serial ports at large sites and 4 ports at smaller sites.”

Implementation of the first 80 or so OOB devices began in autumn 2017. In addition to a conventional modem failover, the Opengear console servers offer an integrated solution via a high-speed cellular connection (3G/4G LTE). Opengear IM7200 OOB infrastructure managers are now being used for remote maintenance and proactive monitoring in Quickline’s data centres. Opengear ACM7000 resilience gateways are used for the points of presence (POPs) spread across the country; as compact solutions they are tailored to smaller remote sites.

“We are planning to change all our sites successively to 4G OOB technology” Michel Renfer, IT Manager Strategy & Network at Quickline, explains. “In the next three to five years we will probably upgrade a total of 200 to 300 sites.”

The integrated wireless option offered by the OOB console servers also scored highly in terms of operating costs:

Apart from the hardware, another factor was that the costs for our previous out-of-band access system vis DSL weren’t scalable” Michael Renfer reveals. “As well as selecting a new OOB management system we have found a wireless access solution which is so much cheaper in terms of operating costs than the previous wired DSL access.

Simon Koch adds “wireless give us much more flexibility because copper wires are no longer laid in many new sites, particularly in new buildings; they only use fibre optics which means that wired OOB access isn’t available anymore.”

Centralised management of the whole OOB infrastructure

“With the large number of sites that we have, a centralised management system with automatic configuration for simple scalability and device provisioning is very important. That’s why the new OOB solution had to have a software management platform” Simon Koch explains. “The new out-of-band management software tool allows our administrators to keep an eye on all installed OOB console managers and connected devices from a central location. In addition, new devices can be configured and provisioned very simply.”

Quickline is using Opengear’s Lighthouse OOB management software. As a central management platform for remote access gateways, the solution is implemented as a virtual software appliance and implements OpenVPN encrypted tunnels to gateways for all LAN, WAN and wireless remote access connections. Lighthouse can be installed on any VMWare sessions and also has a RESTful API interface, allowing the platform to be integrated easily in other management tools already installed.

Devices can be grouped according to users, sites or manufacturers, making for clear and simple management. The management software gives a status overview over all access gateways or nodes. Nodes are declared to the software tool and the process is simplified using enrollment bundles. These bundles combine a unique registration token with user-defined tags such as a geographical location, a department or even a rack position. In addition, specific strict access authorisation can also be defined.

Zero touch provisioning (ZTP): Rapid preconfiguration and provisioning

Time-saving provisioning of devices was another factor in our decision” Simon Koch adds. “Our administrators use the management software to integrate new devices into the existing network structure quickly and without local intervention on site. They have the option to automate node configuration and the provisioning process for new devices.

Once the console servers have been preconfigured, they only have to be hooked up on site (ZTP, zero touch provisioning). Several units are preconfigured at the same time. This reduces provisioning costs and sources of human error.

Out-of-band management means a fast and targeted response

“Out-of-band management helps our engineers enormously with general maintenance work on our backbone”, Michel Renfer explains. “If something isn’t working as it should, which can always happen, our technical staff can see immediately the status of the particular device. They can intervene directly without having to go on site. It is especially important to be informed at all times of the status of devices, for example, when we are carrying out maintenance work on a core router, such as a software update. Since in-band connectivity is interrupted at times, which is inevitable, we can monitor the status of devices permanently out-of-band.”

Around one year after introducing the new out-of-band management solution, the view at Quickline is positive throughout. Simon Koch sums up:

“We are very satisfied with the new OOB solution, particularly since we can avoid on-site intervention which means considerable savings in time and hence costs. We can reduce unnecessary downtime, guarantee quality support for our customers and we can act quickly and precisely to resolve any network failures or technical issues. And should a visit on-site be necessary at any point, our support staff can use the OOB remote maintenance solution to identify in advance which spare part is needed.”


The Quickline Group is one of Switzerland’s leading full-service providers of communication and entertainment. The third largest TV provider and fourth largest internet provider in the country, the organization provides private customers, SMEs and network operators a wide range of products.

SD-WAN Deployments in Finance

Download our White Paper today!

There has been a widespread move towards SD-WAN in the financial sector. An industry that embraced features such as online banking and mobile apps, is continuing the tech forward mindset by using technology to improve network performance, communications and speed. IoT and mobile devices are just a few applications that have increased customer expectations and to continue to meet these, financial institutions must build their online engagement model. As more are added to the network, performance can suffer and onsite technicians distributed sites are few and far between. Providing improved security, reliability and performance, SD-WAN ensures a more streamlined solution with less need for a technician onsite. Additional benefits of SD-WAN for financial institutions include:

Bandwidth Optimization

More than 36% of organizations have chosen to move to SD-WAN because of the optimization of bandwidth.1 Providing the ability to utilize a variety of connectivity options, most jump at the chance to eliminate expensive MPLS circuits, it continually searches for the best path as it carries packets across the network. This is an immediate benefit, as other most other solutions have little capability to actually prioritize the data being carried.

This allows financial organizations to use lower priced bandwidth products, without sacrificing quality or consistency. It also provides consistent communications – with the amount of transactions being processed in finance this is a necessity. Now these organizations like credit unions and banks, with distributed locations, can also switch to lower data packages allowing them to reduce costs and improve communications.

WAN Integration

Finance has a variety of business distribution models – each with challenging network needs. Requiring an always-on network, any small disruptions can quickly escalate. In fact, 28% of organizations indicate that the ability to use existing architecture in an aging network is a major concern. SD-WAN provides organizations with greater control over solution used across each network.

Automation at Distributed Sites

Financial institutions have distributed locations and without the proper solution, functioning as a cohesive unit can be a challenge and if not properly managed, it can become a source of operational and financial inefficiency. This makes SD-WAN a perfect fit for these distributed organizations. More than 28% of organizations state a need for improved automation and self provisioning for their network.2 This would allow financial institutions to manage and view the WAN as one entity, instead of treating each endpoint as a standalone resource.

SD-WAN has a variety of benefits, but it does have points of failure. To learn about adding Smart Out-of-Band to your next deployment for always-on access, see our storygraphic.

The Problem with POTS Lines

What’s IP-based, cost efficient and rapidly replacing Plain Old Telephone Service (POTS) infrastructure? That would be 4G LTE. Over the past few years, many organizations are moving towards deploying newer technologies like 4G LTE instead of legacy POTS lines to use for Out-of-Band (OOB) connectivity or site backup. Opengear has been on the front of the technology wave, providing embedded cellular as part of our Out-of-Band offering since 2010. We understand the ins and outs of this technology boom- like how LTE allows for Smart Out-of-Band™ (Smart OOB) to be easily implemented into any infrastructure with its reliable, fast and secure failover for wireless connections.

Using POTS Lines

Remember the 80’s and 90’s and those sweet sounds of modems training up to provide blazing fast connections of 38400 Baud? Now do you remember the disconnects during downloads, the no answers and the busy signals? These memories are starting to quickly become not so fond. Do you want to run your OOB emergency access to infrastructure like this? Most would say no. The truth is carriers want to move away from POTS due to the cost of maintaining copper lines. This cost is passed on to you if you happen to be in an area where you can still get a POTS line. Most office phone connections today are now VOIP and running POTS over VOIP can be challenging as well. All of the these have contributed to the decline of POTS usage, in fact, the U.S. Federal Communications Commission (FCC) is vying for POTS lines to transition to wireless connectivity – which most already seem to be doing. The National Health Center has projected that only 6% of the population are actually using POTS lines.1

Top 3 Reasons For the Replacing POTS Lines
  1. Maintenance: The Communication Workers of America reports that many phone companies aren’t consistently repairing phone lines due to the cost, which delays how quickly linemen are sent out on calls. It’s estimated that $13 billion is spent every year to maintain old telephone networks – and from that kind of investment the benefits gained in return aren’t notable.2 In fact, in 2018 carriers including Verizon and AT&T will no longer have to install or maintain existing POTS lines. This means that POTS lines services and maintenance prices, which already are high, may increase. The Internet Innovation Alliance (IIA) states that there’s disincentive for phone companies to spend on infrastructure.
  2. Inclement Weather: Rain, lightning strikes, snow and tornadoes, when inclement weather strikes, many times phone companies are left to try and quickly remediate the issue not knowing where to start when the damage is excessive. In just a matter of seconds, these weather events can take out a landline.
  3. Costs: When it comes to maintaining POTS lines it can become costly with all of the purchasing needed for onsite hardware, IT resources needed for reconfigures and power cycle modems that are not responding. On average, it can cost $50 to $100 per month to have one POTS line and keep in mind you need two, one calling line and one answering line. Anyone that has already invested in the infrastructure can head on over to POTS to cellular return on investment (ROI) calculator to see how cellular will pay for itself.
Failover to Cellular by Opengear

Opengear has made the most dependable console server which can be seen within the features of each device. Our console servers enable uninterrupted availability for remote networks utilizing 4G LTE for either OOB needs or failover needs and remediates network issues remotely by providing a cellular backup to small remote sites. Need more reasons to switch to cellular?

  • Opengear’s IP interface is always available, but we also provide other options to have it deactivated by default and utilize SMS or Failover mechanisms for activation. This allows you to control when the IP address is reachable, eliminating unwanted guests. In addition, we also have a built-in firewall to allow you to tightly control who has access when the interface is active. Being an IP interface you can also monitor it with network tools ensuring maximum availability and visibility.
  • It’s inexpensive! Carrier plans start as low as $5/month for 1 MB of data. That doesn’t sound like much in today’s world – but for OOB purposes, it’s a great start. Your average SSH session to a router console to issue some commands run from 200 to 400k worth of data! If you do need more data, you can raise the data plan to accommodate your needs. Below are some going rates for the major carriers in the US:

Don’t take our word for it, reach out to your carrier of choice and ask them about their Machine 2 Machine plans for IoT devices. If you do plan on using Opengear as a failover connection, you will need to choose a data rate plan accordingly because there is more data than just for OOB usage.

  • Opengear devices provide both Out-of-Band and Failover to Cellular™ (F2C) capabilities. This allows you to not only use it for Out-of-Band, but also as a backup data circuit using the LTE interface as an internet connection, or if you add in IPSEC/VPN back to your main site, a backup link. This will allow your users to stay connected at remote locations if and when the primary WAN service were to go down.

Make your job easier. Don’t rely on antiquated modems and traditional lines as your troubleshoot, backup connection. Upgrade yourself to Opengear’s OOB and failover to increase your network’s resiliency using our embedded cellular technology. This means better availability, reliability, dependability monitoring and performance – all at a fraction of the cost of a POTS line connection.
