ISDN2 & ISDN30
With ISDN2 you'll have 2 lines/channels to use separately or simultaneously, so you can do 2 things at once.
A single high-quality ISDN30/30e connection has between eight and thirty 64k channels. In normal operation you use these separately, which means you can perform different tasks simultaneously.
For ISDN 30, there's a choice of options to cover your lines should they ever be disrupted. We can re-route circuits and calls to various locations, meaning your business isn't affected.
See the options for Assurance Continuity.
You can have an unlimited number of DDI numbers, allowing frequent callers to get straight through to the person they wish to contact, without passing through a switchboard.
Using Fast File Transfer you can send files directly over the ISDN network to another computer with ISDN access and compatible file-transfer software.
Useful for large documents, graphics or video files. It is often quicker and cheaper than using a courier.
If you wish, you can have separate phone numbers for telephones or other devices connected to your circuit.
If you use a switch/PBX, you can have an unlimited number of Direct Dial-In (DDI) numbers.
You can add further connections to your installation, increasing the number of simultaneous calls and/or available data bandwidth.
