1. multiACCESS - GSM Gateway

2. Agenda What is it? Topex multiAccess characteristics Where does it fit? Conclusions

3. What is it ? GSM Gateway enabling interconnection of VoIP & PSTN network with mobile networks Assures international transport of voice channels via an Internet connection Support for 30 GSM channels Integrated VoIP gateway

4. Networks Mobile Networks: GSM, UMTS, CDMA2000 VoIP networks: SIP,H.323 Fixed networks: SS7,ISDN, R2, R1.5

5. Building blocks It starts with a rack-chase - dimension 7U You add the mandatory cards (source and processor) on the front-side of Topex multiAccess rack on the dedicated positions (1 and 3); You have another two special positions: ●A VoIP or 2E1 card into the position between the source and processor cards (slot no.2); ●In case a VoIP card is mounted in slot no.2, the E1 card will be added in the slot no.4 All the cards are hot-pluggable – no need for restart when replacing 1 – Power supply card 2 – VoIP or E1 card 3 – PG cards

6. Card components The other Topex multiAccess front-side cards can be: GSM cards with 2 modules on each board UMTS cards with 2 modules on each board CDMA cards with 2 modules on each board

7. VoIP cards Topex multiAccess can perform both SIPv2 and H323v4 signaling VoIP cards scale 8/16/30/60 RTP channels Topex multiAccess can perform transcoding functions Its DSP “speak” G.711 A and μ law, G.723 and G.729 Topex multiAccess can transmit T.38 Fax over IP

8. Fixed-line cards ISDN-PRI signaling, DSS1, Q.931 SS7 signaling – MTP1, MTP2, MTP3 and ISUP CAS R2, CAS R1.5, CAS DTMF Custom signaling for special applications

9. Administration Windows based GUI CLI – Linux SSH console Configuration in “real-time” – modifications happen as we speak

10. Applications Gateway between VoIP and Mobile Networks Gateway between TDM and Mobile Networks Enterprise Hybrid telephony SME solution Small capacity softswitch

11. Enterprise telephony solution PBX ISDN-PRI PSTN carrier Mobile network Enterprise Office IN & OUT VOIP Provider Call to GSM Least Cost Routing IP Call Least Cost Routing

12. Gateway between VoIP and Mobile Networks Up to 32 mobile modules Each module can connect to GSM,CDMA2000 and UMTS networks Call Back capabilities: classic and cross connect Mobile Network 30 channels VoIP network IP PBX EnterpriseService Provider WAN Least cost Routing Call to IP1 Call Back IP1 IP2 IP30

13. Conclusions Address a wide range of applications Advanced diagnosis program that monitors the system operation allowing the remote operation. Well fitted solution for small-size VoIP carriers or enterprises
