Protect Your Organization in the Event of a WAN Outage

For organizations with remote locations, reliable connectivity between sites is often a critical requirement. It's important for these organizations to have contingency communication plans in the event of network disruptions. With the Remote Site Failover functionality, Syn-Apps' Paging Relay provides true fault-tolerance protection in the event of a WAN outage.

How Fault-Tolerance Works with Paging Relay: 

During normal operations, all notifications are answered by SA-Announce at the primary location (Location 1). If a remote site experiences a wide area network outage and the SA-Announce server is not accessible, notifications are automatically routed to the Paging Relay locally via a backup call control (Location 2).

In active failover mode, users at the remote site can pick up a phone, dial the same pre-configured extension to reach the Paging Relay, and broadcast a live page to supported IP phones, analog and IP speakers.


Let's recap!

The Paging Relay is an innovative, all-in-one device that is easy to install, provides enhanced services at a fraction of the cost, and requires virtually no configuration. Key features include:

  • Unicast to multicast conversion - Converting a single unicast stream into multicast decreases network bandwidth and provides clear, intelligible audio - which is important for communicating to personnel.
  • Two type of contact closure connections - Smart detection and automated alerts can help improve situational awareness and keep personnel safe.
  • Various musical capabilities - Streaming live background music or playing music on hold creates an ambient environment for customers waiting for assistance.
  • True fault-tolerance protection - The Remote Site Failover functionality keeps remote locations connected and provides live communication, during a network disruption across the WAN.

How Converting Unicast into Multicast Can Optimize Your Network

Posted by Sydney Hirshberger on Wed, Oct 26, 2016 @ 09:00 AM

Paging_Relay_Banner_3.png*This is the first of a four-part series highlighting the various features of Syn-Apps' patented Paging Relay.

Syn-Apps’ Paging Relay is a small, patented PoE network appliance that provides customers with a number of communication solutions. It enables connectivity to analog endpoints, contact closure devices, alarm panels and more. The device can also be used to configure remote site failover, broadcast background music, play music on hold, and alert staff of incoming calls after business hours with the night ringer functionality.

One key feature of the Paging Relay is its ability to significantly reduce bandwidth consumption by converting incoming unicast audio streams into multicast to destination sites across the WAN.

What is unicast?

Unicast is an industry-standard transmission method of sending data to a single network destination identified by a unique IP address.

Unicast Traffic Flow

Above: Each endpoint is sent the same set of data.


What is multicast?

Multicast sends one data stream to multiple endpoints and optimizes network performance by controlling network traffic and reducing the bandwidth load on network devices.

 Above: Data is sent to designated endpoints.


How can the Paging Relay help?

By converting a single unicast stream into multicast before delivering a notification, the Paging Relay decreases network bandwidth and provides clear, crisp audio announcements to designated endpoints — like IP phones, IP speakers, or traditional PA systems.

Unicast to Multicast with Paging Relay

Above: One unicast stream is sent from the server to the Paging Relay, which then converts the stream into multicast and sends individual streams to each designated endpoint.


Ask yourself this: Could your organization benefit from taking additional measures to optimize your network - such as reducing bandwidth consumption or broadcasting intelligible audio notifications?
