The ESBC 9580-4B is the most highly integrated and versatile Enterprise Session Border Controller (ESBC) solution in the industry. It combines Enterprise Session Border Controller, PRI gateway, business line FXS ports, switched data port, DOCSIS 3.0 cable modem, and internal battery, all in one unit. The ESBC 9580-4B can be used by service providers as a PRI gateway to offer SIP trunks to enterprises with legacy TDM PRI PBXs (Figure 1), as an ESBC with B2BUA for IP PBXs (Figure 2) or with SIP ALG for IP Centrex (Figure 3), or as a complete ESBC solution for the combination of all of the above.
