Nikel-TE
The Challenge:
The task of the customer was to implement a unified multi-service network on the basis of packet data transfer and IP-protocols. One of the requirements was to implement a telephony service that is to use a unified packet network as a transport backbone, and to connect the digital PBX with EDSS-1 protocol.
The Solution:
AT Software has developed Nikel-TE network system that is a Distributed Telephony Exchange. It consists of multiple EDSS-1/IP gateways connected via TCP/IP.
The distributed telephony exchange converts voice data between circuit-switched EDSS-1 part and packet-switched TCP/IP part with RTP/UDP protocol and G.711/G.729a codec algorithms, as well as provides standard PBX features.
Distributed telephony exchange supports brand Lanit-Tercom PBX O&M software as well as remote network management with SNMP protocol.
Tools and Technologies:
• VHDL, Leon, TMS320C6415 DSP;
• Linux, Linux kernel modules & drivers;
• EDSS-1, TCP/IP (RTP/UDP, SNMP), VoIP
