Digium 4 PORT Digital PRI Cards

Quad Span

Digium's quad span digital interface cards support 96 (T1 / J1) or 120 (E1) connections to PSTN trunks over four spans (digital circuits). Built exclusively for use with Asterisk and Asterisk-based communications systems, the quad span digital cards provide the best value in digital connectivity.

Quad span digital cards are available in PCI and PCI-Express form factors. All quad span models can be combined with an Octasic DSP-based echo cancellation module from Digium to provide effective hardware echo cancellation across all channels.

Note: The TE410P model supports a 3.3v PCI slot only - typically available on newer server motherboards and in 64-bit PCI bus architectures. The TE405P is for use only with a 5.0 volt PCI slot.
