ISDN 2

Basic Rate has two 64k/bit B channels (lines) which can be used for voice, data or video together with one 16k/bit D signaling channel which runs the European signaling protocol Q.931 otherwise known as I.421. ISDN 2 is generally provided over copper wire.

Benefits of using ISDN:
DDI: (Direct Dialing Inwards)
Your key customers can access you directly by being given a specific number to dial.
Calls can be directed to your desk phone or mobile relieving your switchboard operator to answer more necessary calls.
There will be no more need for direct lines for Directors or Fax machines therefore making an instant saving on line rentals.

CLI: (Calling Line Identity)
You can give your customers a personalised service by knowing who is calling you as their name appears on their display.

CTI: (Computer Telephony Integration)
By linking your computers with your telephones, customers' records can pop up the instant they are calling you, allowing you to deal with their enquiry in the most efficient manner possible.

Trunk to Trunk Transfer:
If you are often out of the office or need to receive calls out of hours ISDN allows calls to be transferred to another phone or mobile seamlessly.

High Speed Data Transfer:
ISDN ensures that your data travels up to 9 times faster than on analogue lines. This can be used for Videoconferencing, PC application sharing and Internet access and faxing. The higher speeds ISDN offers ensures that all these communications become faster, cheaper and more reliable.
