AMTELCO XDS is pleased to announce the New 2-Port and 4-Port E&M Gateway Appliances! These new appliances have the following features:
  • Available with two or four (4-wire) E&M ports
  • Quad RJ45 E&M interface connectors, including status LEDs for each interface
  • Supports standard Type I, Type IV, Type V, and manual signaling protocols
  • Full-featured Asterisk switching to and from SIP service providers
  • Web-based programming
  • May be configured using the Asterisk Switch engine as an E&M/Radio to VoIP/SIP gateway
  • Power over Ethernet (PoE) is supported, as an alternative to (or in addition to) an included 5VDC wall adapter
  • External power switch allows for controlled power down of box
  • Appliance dimensions approximately 92 mm (W) x 160 mm (L) x 48 mm (H)
NEW Dual T1/E1 Appliance!

The XDS Dual T1/E1 Appliance provides an Asterisk®-based telephony system with two T1/E1 interfaces. It can be used as a VoIP gateway product supporting up to 60 VoIP channels connected to the PSTN or a PBX environment via T1/E1.

Additionally, the T1/E1 interfaces can be used in a high-impedance mode and combined to provide a tapping/monitoring function. In this mode, incoming calls from either interface are sent to the Asterisk dialplan for connection to other IP telephony resources. The audio streams from the T1/E1 interfaces are combined and sent to the connected VoIP resource for recording or monitoring, as needed.

The XDS Dual T1/E1 Appliance has the following features:

  • Two T1/E1 interfaces (software selectable) supporting PRI/PRA ISDN
  • Software programmable termination impedance, including a high-impedance monitoring mode
  • Web-based programming
  • Linux operating system
  • Full-featured Asterisk switching to and from SIP service providers
  • Hardware-based echo cancellation available*
  • Power over Ethernet (PoE) operation is available, supporting IEEE 802.3as standard as type 1 PD (13W)
  • Can be powered from a +5V DC adapter if PoE is not used or both for redundancy
  • Power switch for clean shutdown and startup of the appliance
  • Single RJ-45 connector for connecting the T1/E1 interfaces
  • Status LEDs for each T1/E1 interface
  • DMA audio transfers to minimize software overhead for transferring audio to and from the T1/E1 interfaces
  • Appliance dimensions approximately 92 mm (W) x 160 mm (L) x 48 mm (H)

*Telephony systems may under some circumstances experience the phenomena of excessive echo where speech is reflected from the far end with a noticeable delay. This is particularly true when the call involves VoIP, satellite links, or analog endpoint devices that combine the audio paths into a two-wire interface through a hybrid circuit. To combat this echo, the T1/E1 appliance is available with an optional echo cancellation feature that is integrated with the ISDN interface.
