Single-span T1/E1/J1/PRI interface

This Digium PCI-Express card provides one digital span for T1, E1, J1 or PRI telephony connections. It includes hardware echo cancellation to offload voice processing from the host system. The card targets businesses integrating legacy TDM circuits with modern VoIP platforms such as Asterisk.

PCI-Express slot required for installation

The card occupies a standard PCI-Express slot and draws power from the bus, so no external supply is needed. Driver support is available for Linux-based telephony distributions, freeing CPU cycles for call handling rather than signal processing. Buyers needing multiple simultaneous spans or analogue FXS/FXO ports should look for multi-span or hybrid alternatives.

Highlights

  • Single T1/E1/J1/PRI span connects to digital telecom lines
  • Hardware echo cancellation removes voice echo without CPU load
  • PCI Express interface fits modern servers and workstations
  • New condition ensures full manufacturer reliability
