One.Demarc Details


What is One.Demarc?
The One.Demarc solution is a TELIN SD-WAN implementation that leverages Peplink SpeedFusion and eSIM service technologies. This integration enables a sophisticated VMPLS connection between the client’s local network and our centralized data center. The primary objective is to uphold the integrity and reliability of voice communication by integrating cellular failover mechanisms.
How Does It Work?
TELIN provides you with a device to be positioned at the edge of your network, operating parallel to your existing data infrastructure. Phone traffic is isolated and routed through our edge device, then transmitted over a Speedfusion VPN directly to the hub in our data center. We provision an eSIM onto the device and include 1GB/month of 4G/5G* data. If a local ISP goes down, traffic seamlessly transitions to the cellular network without interrupting your call.
This service is offered at no upfront cost. The starting price varies from $85 to $150 per month for a one-year term, with the option to switch to a month-to-month arrangement after the first year. It also includes 1GB of data per month, with extra data priced at $10 per GB.

Main Highlights
• Zero CAPEX: Benefit from hardware, service, and reliability without any upfront costs.
• eSIM: Enjoy 1GB of data per month, available in 4G/5G* where accessible.
• Hot Failover: Our “Stateful Transfer” feature ensures active calls remain uninterrupted during the switch from your ISP to cellular in case of internet outages.
• Bandwidth Bonding: Combine your ISP and cellular networks to maximize connection speed, particularly useful in areas with limited connectivity (Additional cellular usage charges may apply).
• WAN Smoothing: Reduce latency and packet loss by redundantly transmitting packets across both connections, prioritizing network reliability over bandwidth consumption (Additional cellular usage charges may apply).
• Speed Fusion: Utilize unbreakable enterprise VPN technology via SD-WAN to establish a highly available VMPLS, ensuring top-notch connection quality and survivability.
• Customer to PSTN Tunneling: Leveraging TELIN’s One.Demarc and complimentary Megaport X-connect, establish a highly available, private, and secure connection directly from your customer’s site to the PTSN, bypassing any downstream carrier issues.
