JSS has a fully deployed and sophisticated digital switching network using Sonus Networks, the premier «Next-Generation» Soft-Switch technology, for emerging Voice-Over-IP (VoIP) for incoming/origination as well as outgoing/termination interconnections. JSS has a fully redundant IP network of private MPLS connectivity, and Public-IP via Tier-I carriers, and over a hundred traditional Time Division Multiplexing (TDM) Sonus trunk ports at DS-3 signaling levels.
Each JSS’s super POP has a fully redundant Sun Micro-Systems processing clusters and dual Cisco series Gateways. JSS augments the network with traditional TDM switching based on Cisco switches. Additional Points-Of-Presence for customer and carrier interconnections are available in forty eight (48) States and sixty five (65) countries. JSS Networks has customers in the US, Canada, United Kingdom, Switzerland, France, Germany, Ireland, Finland, Russia, Ukraine, Israel, India, China, Japan and Australia.
The ingress network switches are connected to Tier I providers, for both incoming Direct Dial and Toll Free calls, by diversely routed interconnections at DS-3 high capacity digital facilities and Optical Fiber connections in all cities for TDM traffic, and Public-IP Tier I Internet Service Providers for SIP traffic. Through a highly complex Least Cost Routing (LCR) engine and switch interface, JSS provides over forty (40) termination (or egress) route choices on Tier I, II & III providers for granular Intra-state, Inter-state and International call completions, based on “partitions” offering several Grades Of Service (GOS).
JSS's network has ‘extended reach’ with Non-Geographic Numbers (NGN) from sixty five (65) countries OnNet, International Direct Inward Dialing (DID) services from seventy (70) countries, along with International Toll Free Service (ITFS) from one hundred and one (101) counties for either dedicated TDM interconnections in the US, UK, France, Ireland and Russia or SIP interconnections world-wide. NGN are ‘in-country’ domestic Toll Free numbers, while DID are PSTN or ‘local in-city’ numbers.
Carrier-Grade SS7 Signaling is used in all switching centers for fast and robust call set-up, feature richness and superior accurate billing records. AT&T, Qwest, Verizon, Level (3), and VeriSign provide JSS’s domestic US SS7 networking. Inter-working between platforms is seamless with JSS’s network.
A fully empowered Network Operations Center (NOC) is located in Staten Island, New York US for engineering, network design and routing instructions, as well as monitoring all vital signs of the numerous network components world-wide. A fully redundant Network Monitoring Center (NMC) is located in Poughkeepsie, New York providing Tier I support and fail-over capabilities.
Alternate Routing and Disaster Recovery programs can be implemented within minutes should either network hardware components or digital interconnection facilities fail. Manned 24×7x365 by network engineers JSS customers and vendors are afforded swift response to network issues and efficient restorations, many times corrected even before end-users have noticed.
