WSS100-TG is a VoIP trunking gateway for service providers and medium to large enterprises. Built in IP interfaces and T1/E1 interfaces, it bridges packet networks to traditional voice network trunking facilities which include PSTN class 4 switches, class5 swithes, and various enterprise PBXs. It supports ISDN PRI signaling protocol for interconnection to PSTN switches or PBXs and SIP protocol as the primary interface to soft switch. WSS100-TG has successfully completed interoperability tests with most advanced soft switches in the global market place.
WSS100-TG is designed with form factor and mountable rack in the 19 inch shell. It is equipped with a main control module, an interface slot to house 4-port T1/E1 module (WSS-4T1/E1). It also includes a DSP expansion interface on the main module to incorporate more voice processing power through a DSP sub-module. In addition, WSS100-TG offers redundant power supply option and hot swappable modules to guarantee high service availability.
Flexible configuration of one to four E1 / T1
Guarantee 4E1 120 DS0 voice processing with any codec (G.711u/aLaw, G.723.1,G.729,GSM,iLBC,T.38)
Ideal PSTN termination for IP phones, VoIP gateway, IPPBX, PBX access
Embeded with RTP voice proxy, Digits translation
Auto Dial and RADIUS billing interface for CDR
Enterprises can benefit from a variety of valuable applications such as PBX extension, remote office connectivity, long distance consolidation and call centers, IPPBX's SIP trunk
Service providers can deploy numerous VoIP applications such as SIP Trunking,Wholesale VoIP Termination, Calling Cards, Tandem Switching and Least Cost Routing.
Voice processing capability is the most important requirement and measurement for all trunking gateways. WSS100-TG configured with one to four T1/E1 interfaces can maximally process 120 simultaneous VoIP calls. WSS100-TG embeds powerful DSP technology which possesses 4800 MIPS processing power, for full load voice processing to support CODEC (G.711, G.729A, G.723,iLBC,GSM), echo cancellation (G.168), DTMF relay (RFC2833), and fax relay (T.30, T.38) etc.
WSS100-TG supports all kinds of features to satisfy various application requirements. Features include: Calling/Called Party Number Translation, Routing Selection, RADIUS Billing Interface, Second Stage Dialing and Ring-back Tone, DTMF Auto Dial, Tone Detection, RTP voice Proxy (for NAT traversal), T.38 Fax Relay. WSS100-TG supports ISDN PRI and SIP protocols and it is the ideal PSTN trunking gateway for IP phones, PC phones and PBX bridge to VoIP services.
The WSS100-TG supports use-wide ISDN PRI connections to class 4/5 switches such as those offered by Nortel, Lucent, Alcatcl, Siemens, Huawei, ZTE and others. It also supports network-side ISDN connections to ISDN PBXs and supports features such as Caller ID and Direct Inward Dialing.
The WSS100-TG supports wide array of the SIP inclustry standards that enable it to interoperate with SIP-based application servers, media servers and large variety of IADs.
Like other WSS series VoIP products, WSS100-TG has the Web GUI and text configuration interfaces to upgrade, maintain, download log files and collect statistics remotely.
