ESA for New Access Installations

When Public Safety Matters...

Aztek Networks' ESA switch is a vital addition to any new Digital Loop Carrier (DLC), Broadband Loop Carrier (BLC), Multi-Service Access Platform (MSAP) or Gigabit Passive Optical Network (GPON) installation. The addition of the Aztek 5000S gives any new access installation and it's served subscriber community a crucial stand alone switch that preserves the ability to serve dial tone and allows for community dialing and access to local 911 services, even if the host switch goes down or the link to the outside world is cut. The Aztek 5000S is compact (only 1RU high) and hardened so it can be installed adjacent to access systems in new field cabinets or conditioned end office environments. The 5000S implementation is seamless and introduces no additional point of failure into the network architecture. Even if the power is cut to the 5000S system it does not interupt the normal flow of traffic between the access system and the host switch.

Triple Play Access with a Back-Up Voice System

Installations with Aztek's ESA switch adjacent to new copper or fiber triple play access systems , such as BLCs or GPON, offer subscribers the same level of reliability and access to emergency services as traditional Class 5 remote switch units. The Aztek ESA switch monitors the link between the access system and the central office host switch, remaining entirely passive until there is a failure in the link. While the ESA switch is in monitor mode, all calls are switched by the central office host and all 911 calls are routed to a regional public safety answering point (PSAP) where operators dispatch appropriate local emergency responders. If the switch link fails, the Aztek ESA system becomes active and completes all local calls. Any 911 calls made during this time are routed by the Aztek ESA system directly to local emergency responders. Once the central office link is restored the ESA system reverts to passive monitor mode. The Aztek 5000S will monitor and interoperate with any standards-based GR-303 or IP access system.
