07/05/18, Dublin, Ireland. Deutsche Telecom Akliengesellschaft (DTAG) is turning off legacy ISDN networks, which will cause considerable disruption to customers with equipment and applications that rely on ISDN/X.31.
Read the full article ‘Ein Datendienst Verschwindet’ in the German technology magazine ‘Funkschau’, discussing the effect of such legacy migration by large telecoms providers on end customers. It discusses the Virtual Access solution that allows customers to continue operating their existing equipment without disruption using products that emulate ISDN/X.31 services over fully supported IP networks.
The Virtual Access solution
Virtual Access supplied the latest network technology for Datex-P and ISDN PH, and now offers a new solution suitable for the adaptation of PSPDN customer lines. The GW7600V, GW6600V-F and the AOS were originally intended for access to a central PSPDN network over IP, as Datex-P currently works. However, for a small number number of ports these routers can also provide packet network connectivity without the need for the core network technology but also without the special PSPDN switching functions.
|Access Method||Router||IP Access||Central Site Aggregator||Host Access|
|X.28||GW7600V-S||LTE, DSL, Fibre||GW7600V-S or AOS||Leased Line or XMP|
|ISDN/X.31||GW6600V-BRI||LTE, DSL, Fibre||GW7600V-S or AOS||Leased Line or XMP|
|Leased Line||GW7600V-S||LTE, DSL, Fibre||GW7600V-S or AOS||Leased Line or XMP|
*AOS is recommended when full emulation of legacy X.25 is required.
