SPC8800-GT1000 Digital Relay Gateway

The SPC8000-GT1000 from shollper Technology is mainly designed for telecom operators, integrators, value-added service providers, and large and medium-sized enterprises with relevant needs for VoIP services. It is an important component of NGN solutions, located at the edge access layer of NGN networks, connecting PSTN and NGN networks, and realizing the mutual conversion between IP packets and PCM through IP interfaces and E1/T1 interfaces. It carries the task of voice integration between IP domain and circuit domain, and requires a good processing mechanism for echoes on the circuit side. The functions of SPC8000-GT include voice processing, call processing and control, maintenance and management, etc.

SPC8000-GT1000 has echo cancellation technology, which can process the conversion of voice packets and provide signaling such as NO.7, Q.931, Q.sig, etc. Having digital relay interfaces and IP relay interfaces, capable of carrying IP networks and PSTN networks.

Ethernet ports can be provided to interconnect with the softswitch system via SIP/H323 protocol. Connect to PABX/PSTN through E1 interface to achieve interconnection between PSTN and IP network.

SPC8000-GT1000 can complete the conversion between SIP/H323 protocol and NO.7/Pri signaling, while achieving perfect integration between PSTN network and IP network.

As a new telecom grade VoIP gateway device from shollper Technology, SPC8000-GT1000 has more obvious advantages in performance, system reliability, compatibility, and cost-effectiveness compared to other similar products. Efficient software and hardware design, as well as powerful DSP processing capabilities, ensure that the SPC8000-GT1000 can perfectly convert PCM voice signals to IP packet under full load traffic conditions, complete speech signal encoding and decoding (G.711, G.729A), and perform main functions such as echo cancellation.

Product features:

High performance

The SPC8000-GT1000 adopts ARM and DSP chips with strong speech processing capabilities. Through DSP daughter cards, each gateway can have a processing capacity of 6000 MIPS, ensuring that it can still perform speech processing smoothly under full load concurrent operation (G.711 G.729A、 G.723.1）、 Echo cancellation, fax relay (T.38) and other functions.

High security

SPC8000-GT1000 supports comprehensive security protection, including support for SSH protocol, signaling and media stream encryption, automatic password strength detection, password modification reminder, anti brute force password cracking, user data ciphertext storage, external network access control, Telnet/SSH function switch, disable Ping function, blacklist and whitelist, system log backup, etc., effectively achieving anti-virus, anti attack, anti-theft, anti eavesdropping, anti port scanning, and anti call fraud.

High reliability and maintainability

To meet the highest reliability requirements of telecommunications operators for gateways, the hardware design of the system, from structure to component selection, fully considers optimizing the mean time between failures (MTBF). The system adopts a web-based graphical management interface, which facilitates user configuration and daily maintenance management.

Reduce costs and ensure work efficiency

SPC8000-GT1000 is a new generation voice gateway device based on IP network. Its powerful SIP, RTP, TFTP, FTP, HTTP, STUN protocols, ISDN PRI signaling, and G.711, G.729A, G.723.1 encoding and decoding technology support can effectively integrate various voice lines, save investment in multi system networking, and improve communication efficiency.
