What is ISDN 2 & ISDN 10/20/30?

ISDN (integrated Subscriber digital network) is a Digital Phone service as opposed to the traditional Analogue Phone service. ISDN is mainly used by business for voice calls but prior to deep penetration of ADSL Internet, ISDN was used as a higher speed Internet product as it could carry twice the speed of data as PSTN.

In Australia ISDN comes in two configurations: ISDN 2 Basic rate and ISDN 10/20/30 Primary rate. In Australia Telstra brands its ISDN products as Telstra On Ramp.

ISDN 2 is mainly used for businesses that need up to 8 phone lines. The lines are integrated in multiples of 2’s (2, 4, 6, or 8 phone lines or channels). With ISDN 2 You also have the option of a Direct In Dial (DID) Number Range.

ISDN 10/20/30 digital phone lines are a larger capacity services that can carry up to 30 individual lines or channels. Configurations available on ISDN 10/20/30 are 10, 20 or 30 Channels. When installing ISDN 10/20/30 a large capacity cable is put in and  the required number of channels are activated. This makes upgrading from ISDN 10 to ISDN 20 relatively easy and the cable is already in place and all that is required is activation of the services.ISDN 10/20/30 is also know as Primary Rate PRA Digital ISDN service or On Ramp.

ISDN services provide better functionality when connected via digital PABX Phone systems and can also provide crisper call quality due to the Digital Transmission. At the telaustralia website there is a lot of information on ISDN 102030
