The Patton SmartNode SN9000 Series Gateway is a flexible digital telecom switch for inter-networking TDM and SIP networks. The units support T1/E1 multiplexing, signaling conversion, digital switching, and media gateway functions.
As an SIP-to-SS7 and SS7-to-SIP Media Gateway the unit delivers the ability to integrate TDM equipment, trunks and inter-connects with SS7 into IP, IMS, and NGN networks. Similarly, the unit can act as a V5.2-to-SIP and DSS1-to-SIP VoIP gateway.
As a Signaling Converter the unit can be used to adapt and interwork between SS7, ISDN-PRI (QSIG), DSS1, V5.2, R2/CAS and Ethernet transferring media across PSTN and/or IP networks. Integrated TDM Multiplexing and Switching provides the ability to cross connect and groom E1 channels between several E1 links.
The unit is equipped with 16 T1/E1 ports, 2x Ethernet ports, and 1x RS-232 console port. It offers a full suite of routing, switching, signaling, and control protocols including IP SIP, RTP, RTCP, TCP, and UDP. On the TDM side SS7 (MTP2, MTP3, ISUP), ISDN PRI (DSS1), V5.2 (LE/AN mode), and MFC-R2.
The unit offers G.711, GSM, G.723, G.726, G.729 compression codecs, fax-over-IP using G.711 or T.38 fax relay. DTMF (via RFC2833) and, SIP INFO (via RFC 2976) are supported as well as Comfort Noise Generation.
The unit is rack mountable in 1U of space and the unit comes with either dual DC (48/60V) and/or AC (100 to 240 V) internal power supplies.
Applications:
The SN9000 is a flexible device used for adaptation of VoIP and TDM telephony networks and equipment. As a Media Gateway, the devices are used to adapt legacy TDM trunks to SIP/VoIP. The unit supports all signaling types used with PSTN network and useful for converting signaling protocols or multiplexing TDM channels.
