Types Of Connections…

In order to know the type of line is going to be most beneficial for your business, you must first consider how they are going to be used.

To help you with your decision, we have provided a brief description of each of the types, below:

  • Analogue Single – Works from the local exchange, suitable for smaller businesses with just one handset
  • Analogue Multi – Also work from the local exchange, but allow multiple calls through one number
  • ISDN2 – Digital, allows up to 8 different channels (extensions)
  • ISDN30 – Like ISDN2, but allows up to 30 different channels (extensions)
  • SIP Trunk – An alternative to ISDN, Sip Trunks connect to your existing PBX using either an IP Card or IP Gateway converter.

At 5G we recognise that every business is unique and that different types of business will require different types of lines. For this, we are more than happy to discuss your requirements with you, but to give you a general idea of the suitability, we have provided a short summary, below:

  • Small Business – Analogue (single/multi), ISDN2
  • Small/Medium Business (High Telephony use) – ISDN30
  • Large Business – ISDN30
Frequently Asked Questions

Can I access the internet over an ISDN line?

It is possible, but not advisable. Years ago, before the introduction of DSL broadband services it was not uncommon for people to use ISDN as a faster alternative to dial up internet. But now with DSL broadband, so much faster at affordable prices, there is no real need to do this.

What is the difference between ISDN2 and ISDN30?

The only difference between the two is the number of channels/terminals that each can support. ISDN2 can support up to 8 channels whereas ISDN30 can support up to 30 channels, significantly more than ISDN2.

Once I make the change over to 5G, how long will it take for my services to become active?

When signing up new customers, we generally quote between 7 – 14 working days for analogue lines and between 10 – 25 working days for digital lines.

What should I do about leaving my current provider?

We want to make your move over to 5G as quick and as painless as possible so we will strive to help you as much as we possibly can to ensure that leaving your current provider isn’t going to break the bank.

Will I save money with 5G?

Yes. If you sign up with 5G, we guarantee to save you at least 10% on your current bill.
