ISDN2e
ISDN2 is especially designed for small and medium businesses with a small phone system. ISDN2 delivers a minimum of two digital lines and is available in multiples of two up to a maximum of eight channels.
ISDN provides:
- Digital line high speed connections for clear voice transmission
- Fast call set-up - virtually instantaneous call connection, improving efficiency
- Unlike analogue lines you can allocate DDI numbers using ISDN2*
*DDI numbers are individual numbers supplied to phones & faxes and are available on both ISDN2 and ISDN30. Using DDI you can allocate individual extensions their own telephone numbers, so callers can ring individuals in your company directly without going via your switchboard. DDI allows you to increase the amount of telephone numbers available for use with your ISDN2 and ISDN30 channels. For example, you can allocate 10 DDIs but only have 6 lines, as not everyone will be on the phone at the same time.
ISDN30e
ISDN30 is especially designed for medium and large businesses with a telephone system (PBX) on their premises. Connecting to ISDN30 is a very cost-effective method of providing large volumes of lines into a business - ideal for call centres or offices with growing communications needs.
ISDN30 delivers a minimum of eight channels and can be increased to any number required.
With ISDN30, you will have a connection into your premises from your local BT telephone exchange, with a maximum of 30 independent channels per ISDN30 trunk.
Finally, with ISDN30 you will still be able to subscribe to additional services.
These include Call Diversion, Calling Line Identity (CLI), Diverse Routing, and Out of Area Service.
PromptCare maintenance which is an integral part of ISDN30 provides a 4 hour response.
