Highest availability for your SD-WAN
This high-end SD-WAN gateway for the first time combines two VDSL Supervectoring modems in just one device for a bandwidth of 2x 300 Mbps when using both connections at the same time. The device alternatively operates on a G.fast gigabit connection. The additional LTE Advanced module is an Internet backup that guarantees highest availability. Equipped with state-of-the-art SD-WAN technology for secure and automated VPN site connectivity, the LANCOM 1926VAG-4G is the top-class solution for mission-critical applications in medium-sized and large branch infrastructures.

Advantages
Multi-WAN & backup
The LANCOM 1926 series are the first routers on the market with two integrated VDSL Supervectoring modems for a total of 2x 300 Mbps. Alternatively, one of the two modems can be used to connect via G.fast at up to 1,000 Mbps. Also, their SFP port allows them to operate directly at high-speed fiber-optic connections. They can also operate with any external DSL or cable modem via WAN Ethernet. The LTE Advanced modem integrated into the LANCOM 1926VAG-4G ensures fast cellular access at up to 300 Mbps, and features two SIM card slots. This makes it ideal for intelligent backup scenarios.

Load balancing
The LANCOM 1926VAG-4G allows multiple Internet access connections to be operated in parallel, with load balancing ensuring that the available bandwidth is used to maximum effect. With the combined operation of 2x VDSL Supervectoring, fiber optic and dual-SIM cellular communications, it provides unsurpassed availability and bandwidth. The LANCOM 1926VAG-4G thus offers the ultimate in future proofing for performance-hungry SD-WAN scenarios in mission-critical environments.

LANCOM SD-WAN – Next-level networking
With LANCOM SD-WAN you can manage and monitor your entire corporate network centrally, cost-effectively, quickly, and stress-free! In combination with the LANCOM Management Cloud, the SD-WAN gateway gives you all the options for an automated setup of secure VPN connections (Auto-VPN) between sites, including network virtualization. Highlight features such as High Scalability VPN (HSVPN) and Advanced Mesh VPN offer you a significant plus in scalability and efficiency for a large number of branches and applications. Furthermore, if multiple WAN connections are defined, they are automatically operated in active/active mode (load balancing), thereby increasing the available total bandwidth. With Dynamic Path Selection and Dynamic Traffic Steering, applications are also dynamically routed via the best connection at any given time.

Next-generation SD-WAN: High Scalability VPN (HSVPN)
The LANCOM 1926VAG-4G supports High Scalability VPN (HSVPN). The ongoing rise of digitalization, greater diversity of applications, and higher data volumes demand powerful, state-of-the-art networks. High Scalability VPN significantly improves the extensibility and efficiency of your architecture. Where previously each individual application required a separate VPN tunnel, HSVPN bundles any number of networks into a single VPN tunnel and transports them collectively to the remote site—with each network remaining secure and strictly separated from the others. The advantage for your business: Considerably fewer VPN tunnels are required, and recovery times are much faster in a failover event.

Secure communication via VPN
With virtual private networks (VPN), you use the public medium of the Internet as a communication path and secure the connection in such a way that the communication still remains completely inaccessible to external parties. This SD-WAN gateway offers you 25 integrated IPSec VPN channels for secure encryption, so that the protection of internal company data is always guaranteed when connecting mobile employees, home offices, or branch offices. With the LANCOM VPN Option, you can also upgrade the device to up to 100 VPN channels, so that the infrastructure can easily grow with your needs without additional hardware.

Advanced Routing & Forwarding
The LANCOM 1926VAG-4G provides up to 64 securely isolated IP contexts, each of which has its own separate routing. This is an elegant way of operating IP applications with one central router and keeping the different communication channels securely isolated from one another.

Professional telephony with the LANCOM VCM (Voice Call Manager)
The LANCOM Voice Call Manager is already integrated into the LANCOM 1926VAG-4G and provides a wide range of telephony functions. It manages all aspects of the telephony and controls all of the router-based PBX functions for SIP, ISDN and analog components. Furthermore, it enables the easy integration of DECT telephones by auto provisioning with the LANCOM DECT 510 IP base station.

Integrated session border controller
The LANCOM Voice Call Manager acts as a session border controller: This ensures that external (unsecure) and internal (secure) networks are kept separate. Also, voice packets are given priority (Quality of Service) thanks to bandwidth reservation, which ensures a higher quality of calls. In addition, the VCM as a SIP proxy enables the professional management of signaling and voice data for high security in the setup, implementation and teardown of telephone conversations, including any protocol conversion by means of transcoding.

Premium full-metal housing
The LANCOM 1926VAG-4G comes in a high-quality full-metal housing with integrated 230V power supply. Thanks to the mounting system, it is easy to install in a 19" rack—with connection ports redirected to the front, it is quick and easy to work with.

Upgrade to up to 100 VPN tunnels
Ideal for fast and secure LANCOM home-office solutions: Upgrade the VPN capacities of your LANCOM router of the 19xx series now in a sustainable and resource-saving way! With the LANCOM VPN 100 Option you can simultaneously and securely connect up to 100 sites or remote employees to the corporate network!

What is active/active (load balancing)?
Active/active distributes network data traffic evenly between Internet connections that are operated in parallel. Data connections are divided evenly between at least two lines, and the individual bandwidths of the lines are combined (2x300 Mbps = 600 Mbps). Even if one line fails, the connection is always secured via the other line.

Application scenario with one client
One client is connected to the Internet via a 1926-series router (2x Supervectoring with 300 Mbps each). The download speed per session is 300 Mbps. Depending on the load, the load balancer integrated into the router now selects Internet line 1 (VDSL) or Internet line 2 (VDSL).

Application scenario with two clients
Two clients are connected to the Internet via a 1926-series router (2x Supervectoring with 300 Mbps each). Both clients are able to communicate with the Internet at the same speed (each at 300 Mbps) as the load balancer integrated into the router evenly distributes the data load between the two VDSL Supervectoring Internet lines (1 & 2). This ensures the maximum utilization of the available 300 Mbps for a significant increase in network efficiency.

Application scenario load balancing and VDSL/LTE backup of Internet connections
Equipped with 2 VDSL Supervectoring modems, the 1926-series allows both Internet lines (1 & 2) to be combined into a load-balancer cluster. Apart from providing fair load balancing, the failure of one of the lines causes the other line to take over the data traffic. The additional LTE/4G modem in the LANCOM 1926VAG-4G can be used as a backup connection in the event that the physical lines should fail—an ideal solution for maximum availability in mission-critical environments.

Application scenario VPN load balancing
The integrated load balancer makes it easy to bundle multiple IKEv2 VPN connections into a load-balancing cluster. Be it in combination with a LANCOM router, a central-site VPN gateway, or the innovative LANCOM vRouter: The load of data traffic is more evenly balanced and the system has redundancy. The combination significantly increases the VPN bandwidth available for multiple clients.

Application scenario load balancing with two All-IP lines
Thanks to the integrated VCM and SBC, the LANCOM 1926VAG and LANCOM 1926VAG-4G are ideal for seamless migration from ISDN/analog to All-IP. SIP lines can be bound to any of the Internet connections (All-IP line 1 or 2). The load balancer is used to distribute the Internet traffic.
