AgendaDescription
Topex Qutex characteristics
Applicability
Conclusions
-
DescriptionIt is both a small capacity VoIP Gateway and
Signaling Converter
Softswitch for small capacity Next Generation Network
SS7 interconnection solution
-
NetworksVoIP networks:SIP,H.323Fixed networks:SS7,ISDN, R2,
R1.5
-
Building blocksIt starts with a 3U dimension rack-chase
You have the mandatory cards (source and processor)
on the back-side of the rack
You add a VoIP card on the back-side of Topex Qutex rack
On the front side you place the 2E1 card
All the cards are hot-pluggable no need for restart when
replacing
-
Card componentsThe features of the cards are:
2E1 cards with signaling:ISDN;SS7;R1;R2.
VoIP cards with signaling:SIP;H323.
-
VoIP cardsTopex Qutex can perform both SIPv2 and H323v4
signaling
VoIP cards scale 8/16/30/60 RTP channels
Topex Qutex can perform transcoding functions
Its DSP speak G.711 A and law, G.723 and G.729
Topex Qutex can transmit T.38 Fax over IP
-
Topex fixed-line cards
ISDN-PRI and ISDN-BRI signaling QSIG, DSS1, Q.931
SS7 signaling MTP1, MTP2, MTP3 and ISUP
CAS R2, CAS R1.5, CAS DTMF
Custom signaling for special applications
-
AdministrationWindows based GUI
CLI Linux SSH console
Configuration in real-time modifications happen as we speak
-
