What is PSTN?
The public switched telephone network (PSTN) is the original and still most common form of telecommunication connectivity and is a much needed part of many businesses. It supplies a single phone line and telephone number.
Is PSTN right for my business?
PSTN is ideal for businesses that require only one or two lines and is also required where a dedicated line is needed, such as fax, EFTPOS , alarm system lines, and ADSL2+ internet connections.
What is ISDN?
Arrow ISDN (Integrated Services Digital Network) is a digital, fixed line service providing high capacity, directly connected voice and switched data. ISDN transforms your existing phone line into the equivalent of 2-30 digital lines depending on which plan you choose. Each digital line can handle both voice, image, data and video.
Is ISDN right for my business?
ISDN is ideal for businesses who require multiple phone lines, and is scalable to suit your needs. If you’re a smaller business you might want to consider our ISDN 2 plan or if you’re a medium to large business, our ISDN 10, 20 or 30 might suit you better.
ISDN also allows your staff to have their own unique phone numbers which can be dialled directly. This is called a Direct in-dial number (DID).
