Lancom 1926VAG-4G

Maximum availability for your SD-WAN
This high-end SD-WAN gateway is the first device to combine two VDSL supervectoring modems in a single unit, delivering a bandwidth of 2 x 300 Mbps through simultaneous use of both connections. Alternatively, the device can also be operated on a G.Fast Gigabit connection. The additional LTE-Advanced module provides maximum availability as an internet backup. Equipped with state-of-the-art SD-WAN technology for secure and automated VPN site-to-site connectivity, the LANCOM 1926VAG-4G is the ideal solution for business-critical applications in medium-sized and large branch office 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 up to 2 x 300 Mbps. Alternatively, they can be used with one of the two modems for G.Fast connections with speeds up to 1,000 Mbps. Furthermore, thanks to their SFP port, they can be directly connected to high-speed fiber optic lines. They can also connect to any external DSL or cable modem via WAN Ethernet. The LANCOM 1926VAG-4G also features an integrated LTE-Advanced modem, providing fast mobile internet access with speeds up to 300 Mbps, and includes two SIM card slots. This makes it ideal for intelligent backup scenarios.

Active/Active (Load Balancing)
The LANCOM 1926VAG-4G enables the parallel use of multiple internet connections for ideal load balancing and increased bandwidth. In mixed operation with 2x VDSL supervectoring, fiber optic, and dual-SIM mobile networks, it delivers unparalleled availability and bandwidth. This makes the LANCOM 1926VAG-4G extremely future-proof for demanding SD-WAN scenarios in business-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! Combined with the LANCOM Management Cloud, the SD-WAN Gateway offers you all the possibilities for automatically setting up secure VPN connections (Auto-VPN) between locations, including network virtualization. Highlight features such as High Scalability VPN (HSVPN) and Advanced Mesh VPN provide you with a significant increase in scalability and efficiency for numerous branch offices and applications. Furthermore, if multiple WAN connections are defined, they are automatically operated in Active/Active mode (load balancing), thereby increasing the total available bandwidth. Dynamic Path Selection and Dynamic Traffic Steering also ensure that applications are dynamically routed via the best available connection.

Next-Generation SD-WAN: High Scalability VPN (HSVPN)
The LANCOM 1926VAG-4G supports High Scalability VPN (HSVPN). Constantly increasing digitalization, greater application diversity, and higher data volumes demand high-performance, modern networks. High Scalability VPN significantly improves the scalability and efficiency of your architecture. Where previously a separate VPN tunnel was required for each application, HSVPN bundles any number of networks into a single VPN tunnel and transports them collectively to the remote endpoint – while each network remains secure and strictly isolated from the others. The benefit for your business: significantly fewer VPN tunnels required and faster failover recovery times.

Secure communication via VPN
Virtual Private Networks (VPNs) allow you to use the public internet as a communication channel while securing the connection so that communication remains completely inaccessible to outsiders. This SD-WAN gateway offers 25 integrated IPSec VPN channels for secure encryption, ensuring the protection of internal company data 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, allowing the infrastructure to easily grow as needed without additional hardware.

Advanced Routing & Forwarding
The LANCOM 1926VAG-4G provides up to 64 securely isolated and independently routed IP contexts. This offers an elegant way to manage all IP applications through a central router and securely separate the various communication channels.

Professional telephony features thanks to LANCOM VCM (Voice Call Manager)
The LANCOM Voice Call Manager is already integrated into the LANCOM 1926VAG-4G and equipped with comprehensive telephony functions. It thus takes over classic telephone management tasks and controls all PBX functions connected to the router, including SIP, ISDN, and analog components. Furthermore, it enables the easy integration of DECT telephony via the auto-provisioning of the LANCOM DECT 510 IP base station.

Integrated Session Border Controller
The LANCOM Voice Call Manager offers standard Session Border Controller (SBC) functions, enabling secure separation of external (insecure) and internal (secure) networks. Bandwidth reservation ensures high call quality by prioritizing voice packets (Quality of Service). Furthermore, as a SIP proxy, the VCM provides professional management of signaling and voice data for enhanced security during call setup, execution, and termination, including necessary protocol conversion via transcoding.

First-class all-metal housing
The LANCOM 1926VAG-4G comes in a high-quality, all-metal housing with an integrated 230V power supply. Thanks to its mounting bracket, it can be easily installed in a 19“ rack – front-facing ports also ensure quick and convenient access.

Upgrade to up to 100 VPN tunnels
Ideal for fast and secure LANCOM home office solutions: Upgrade the VPN capabilities of your LANCOM 19xx series router now in a sustainable and resource-efficient way! With the LANCOM VPN 100 option, you can securely connect up to 100 locations or remote employees to your company network simultaneously!

What does Active/Active (Load Balancing) mean?
Active/Active is used to distribute the data traffic in the network across simultaneously used internet connections. This ensures that data connections are evenly distributed across at least two connections, with the individual bandwidths of the connections being added together (2 x 300 Mbps = 600 Mbps). Even if one connection fails, the connection via the other connection remains secure.

Application scenario with one client
A client is connected to the internet (2x supervectoring, each with 300 Mbps) via a 1926 series router. The download speed per session is 300 Mbps. The router“s integrated load balancer selects between internet connection 1 (VDSL) and internet connection 2 (VDSL) depending on network load.

Application scenario with two clients
Two clients are connected to the internet (2x Supervectoring, each with 300 Mbps) via the 1926 series router. Thanks to the router“s integrated load balancer, both clients can now operate simultaneously at 300 Mbps download speed, as this distributes the data load across both VDSL internet connections with Supervectoring (1 & 2). This allows for a maximum utilization of 300 Mbps and consequently a significant increase in network efficiency.

Application scenario: Connection to G.Fast
Application scenario: Load balancing and VDSL/LTE backup of internet connections
Application scenario: Load balancing and VDSL/LTE backup of internet connections
Thanks to its two VDSL supervectoring modems, the 1926 series enables the aggregation of both internet connections (1 & 2) into a load balancer network. This means that, in addition to fair load distribution, if one connection fails, the other can take over the data traffic. The integrated LTE modem in the LANCOM 1926VAG-4G can be used for a backup connection in case the physical lines fail – an ideal solution for maximum availability in business-critical environments.

Application scenario: VPN load balancing
Thanks to the integrated load balancer, IKEv2 VPN connections can also be conveniently combined into a load balancer cluster. Whether in combination with a LANCOM router, Central Site VPN gateway, or the innovative LANCOM vRouter: In addition to improved load balancing and the takeover of traffic if a connection fails, the clustering significantly increases the VPN bandwidth for multiple clients.

Application scenario: Load balancing with two All-IP lines
Thanks to integrated VCM and SBC, the LANCOM 1926VAG and LANCOM 1926VAG-4G devices are ideal for a seamless migration from ISDN/analog to All-IP. SIP lines can be permanently assigned to the desired internet connection (All-IP line 1 or 2) as needed. The load balancer is used to distribute internet traffic.
