Description
PCI and PCI-Express form factors are available for Sangoma TE435 quad-span digital cards. To provide effective hardware echo cancellation across all channels, all quad-span models can be combined with an Octasic DSP-based echo cancellation module. Sangoma’s quad-span digital interface cards can connect to PSTN trunks over four spans and support 96 (T1 / J1) or 120 (E1) connections (digital circuits). The quad-span digital cards are the best value in digital connectivity because they are specifically designed for use with Asterisk and Asterisk-based communications systems.
