According to the company, as a result of the interoperability testing Cisco can provide an approved solution that allows organisations maximum internetworking between DPNSS
PBX systems and its IP telephony solutions.
The prevalence of DPNSS
as a telecoms only standard and its continuing popularity through the rich set of supplementary services that it provides, has inhibited this happening as most data networking equipment has been built to meet the European Q.
The VoiPZon Product Family integrates IP networks with circuit switched networks based on signaling protocols like SS7 (ISUP), Euro ISDN, DPNSS
At TMA Westell will be exhibiting its new IiQ 2030 DPNSS
to IP Gateway, which enables legacy voice systems to be integrated into new IP networks.
By compressing seven simultaneous calls into the space of one regular 64k/bit call together with the DPNSS
inter-switch signalling, the VCC provides the benefits of a Digital Private Network over ISDN to INDeX customers without the usual costs of leasing a private line.
Intel(R) SS7 products support a wide range of international SS7 variants and switch types and support ANSI, ITU-T, China, Japan SS7, ISDN, NI2, QSIG and DPNSS
To facilitate networking, Ipera 2000 includes QSIG networking capabilities and the full-featured DPNSS
protocol extensively deployed in Mitel's SX-2000 portfolio.
Traditionally, PBXs in these medium and large companies are linked via point to point digital leased lines using signaling protocols such as DPNSS
(Digital Private Network Signaling System) or QSIG (Q-reference point signaling).
The Aculab Groomer supports a comprehensive range of common channel (CCS) and channel associated signaling (CAS) types, such as DASS-2, DPNSS
, BT CAS, Mercury CAS, Euro-ISDN (UK); VN3 (France), 1TR6 (Germany), Swissnet-2 (Switzerland), TS014 (Australia), CAS (Austria), R2 CAS (Portugal), MFC R2 (Belgium), MFC R2 (Norway), Euro-ISDN (all of the European Economic Area) and many others.
This is a Cisco-endorsed product which was specifically designed to allow legacy protocols such as DPNSS
, Digital Private Network Signalling Systems, to run over frame relay, ATM or IP networks.
It supports ISDN using ETS-300 (EuroISDN), VN3 (French ISDN), 1TR6 (German ISDN), and Enhanced DPNSS
(European-wide Digital Private Network Signaling System).
Excel currently supports ISDN Primary Rate Interface as well as DPNSS
and DASS2, two UK variants of the ISDN PRI product.
