Digium TE122BF T1/E1 PRI PCI + HW EC
Numer produktu: VODIGITE122B
- Description
Digium® cards in the TE series are high-performance, cost effective, digital telephony interfaces and support both E1 and T1 environments. The environments are selectable on a per-card or per-port basis. This feature enables signaling translation between E1 and T1 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 and data protocols, including Primary Rate ISDN (both N. American and Euro Standard) protocol families for voice, PPP, Cisco HDLC, and Frame Relay data modes. 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 Digiums 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.
