Solutions Overview

When public safety matters...

Aztek Networks' 5000S offers service providers unparalleled emergency stand alone (ESA) switching capability in a compact form factor and at a cost effective price. The Aztek 5000-series products are the ideal solution for customers who want to add reliability to installed access systems or remove switches and upgrade to triple play via broadband access systems while still maintaining voice reliability and customer access to 911 services, even in the event of a loss of signal from the host switch.

What does ESA mean and how do your customers benefit from this technology?

In a traditional "Class 5" TDM network, subscribers who are not located within the immediate area of a central office host switch are typically connected to the PSTN network via a legacy Class 5 remote switch unit or via an access device such as a digital loop carrier (DLC). Increasingly, carriers are deploying high-bandwidth DLCs called broadband loop carriers (BLCs), Multi-Service Access Platforms (MSAPs) or fiber access systems such as gigabit passive optical networking (GPON). A key difference between a Class 5 remote switch unit and an access system (DLC, BLC, MSAP or GPON) is that a remote switch unit has ESA capability. This means that the remote switch unit is capable of completing local calls even if the link to the host central office switch is severed. Subscribers served from a remote switch unit have more reliable phone service and, assuming the 911 capability of the remote switch is enabled, they have continuous access to emergency 911 responders. Most DLC, BLC, MSAP or GPON systems do not have ESA capability and thus are unable to deliver dial tone to subscribers or complete any local calls, including emergency 911 calls, if the link to the host central office switch is cut.

Aztek brings ESA capability to access systems

Adding Aztek's 5000S True ESA™ switch adjacent to any open-standard access system (DLC, BLC, MSAP or GPON) improves network reliability. ESA from Aztek brings traditional remote switch unit standalone capability to the access system location in an open standards, compact and power-efficient system. With the Aztek 5000S installed adjacent to a DLC, BLC, MSAP or GPON, if the network connection to the host central office switch is cut or the host switch fails, the 5000S detects the loss of signal and assumes all local switching duties, including the handling of emergency 911 calls, until the signal from the host central office is re-established.

ESA for current and future needs

All of the Aztek Networks 5000-series products are based on a common hardware platform and all are IP ready. These products can be deployed in today's TDM networks to meet demand for cost effective, reliable and open standards emergency stand alone switching requirements while giving customers the assurance that their ESA systems can upgrade to IP as their network architecture changes.

These features make the Aztek 5000-series products a critical addition to any new DLC, BLC, MSAP or GPON implementation.  Our products are an ideal solution for switch collapse or the decommissioning of proprietary satellite switching offices or remote switch units. The Aztek 5000-series products are also an excellent addition to existing and installed DLC, BLC, MSPA or GPON access systems in order to provide crucial network survivability.
