Digium Digital Telephony Cards

Digium Digital Telephony Cards: Single Span, Double Span, Quad Span

Digium® cards in the TE series are high-performance, cost-effective, digital telephony interfaces which support T1 and E1 environments. The environments are selectable on a per-card or per-port basis. This feature enables signalling translation between T1 and E1 equipment and allows inexpensive T1 channel banks to connect with E1 circuits. The bus-mastering TE cards improve I/O speed over slave-only architectures, resulting in reduced CPU usage and increased card density per server. The cards provide the power to interconnect traditional telephony systems with emerging Voice-over IP (VoIP) technologies.

The TE cards support industry standard telephony protocols, including Primary Rate ISDN (both N. American and Euro Standard) protocol families. Both line-side and trunk-side interfaces are supported, as well as advanced call features.

The TE cards have been designed to be fully compatible with existing software applications. They are fully integrated with Digium’s Asterisk® software. The open source drivers for these cards support an API for custom application development. With the combination of Digium hardware and Asterisk software, numerous telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications.
