TE235 Digital Cards
Sangoma’s dual span digital interface cards support 48 (T1 / J1) or 60 (E1) connections to PSTN trunks over two spans (digital circuits). Built exclusively for use with Asterisk, FreePBX and PBXact phone systems, the dual span cards provide the best value in digital connectivity.
Dual span digital cards are available in PCI and PCI-Express form factors. All dual span models can be combined with an Octasic DSP-based echo cancellation module from Digium to provide effective hardware echo cancellation across all channels.
