    AMTELCO XDS Introduces E&M Appliance

    McFarland, WI – AMTELCO XDS is pleased to announce the new E&M Appliance, designed to interface to radios. The new E&M Appliance is Asterisk™-based for quick implementation of applications. It is a small, compact, highly cost-effective system providing a self-contained Asterisk LTS switching environment with an integrated E&M analog interface. Bidirectional connection of the 4-wire E&M interface to a corresponding SIP channel on the Ethernet interface is implemented through standard Asterisk dialplan entries. Independent control of the M-lead signaling is supported for radio push-to-talk (PTT) compatibility. External LED indicators provide visual confirmation of E-lead and M-lead signaling activities.

    The gateway unit on the E&M Appliance includes an internal web server allowing user-programmable E&M port settings and arrangement of the Asterisk dialplan through a custom designed web interface, which is accessible through any standard web browser. Additional connectivity to the operating system for administration of the Linux environment or Asterisk utilities is available through SSH. The new E&M Appliance includes protocol support for Type I, Type II, Type IV, Type V, and Manual (radio interface).  

    AMTELCO XDS also offers a T1/E1 Appliance, which can be used as a VoIP gateway using the SIP capabilities of Asterisk. It is the perfect solution for developers who need to add T1 or E1 capabilities into their VoIP systems.

    AMTELCO XDS also offers a complete line of HMP, PCI, and PCI Express Boards, helping developers meet their application needs. Boards are available for E&M, T1/E1/J1, Station, Conference, BRI, and Loop Start.
