PSTN Lines are what most business users call standard telephone lines. A telephone line can be supplied with a single number, but in most cases business users require multiple lines supplied on a single number. This would enable multiple callers to call the phone number and contact the company at the same time. This is called Auxillary Working. If you required up to 4 inbound calls at any one time, you would need four telephone lines, which would mean paying four monthly or quarterly line rentals. If all four telephone lines were auxillary working to a single number then up to 4 people could use these phones lines. If all four lines were in use and a fifth caller telephoned the number they would get an engaged tone.
Analogue telephone lines need to be connected to an analogue trunk port of a telephone system, and if you have four telephone lines, you will need four spare analogue trunk ports to connect these phone line to. So in the case of the Panasonic analogue phone systems you would need the Panasonic KX-TES824 CCU with the optional 3+8 expansion card. This would give you a capacity of 6 lines and 16 extensions. Once the four telephone lines were connected there would be a spare capacity of two lines, so two additional lines could be purchased to provide six lines, therefore six simultaneous calls.
If your business requires more than six or eight telephone lines, you should consider using ISDN or Voice Over IP Telephone Lines becasuse many entry level analogue phone systems so not expand pass eight analogue / PSTN telephone lines. Analogue Phone lines can be connected to all panasonic Phone Systems providing that the analogue trunk card is purchased. Many bsuiness customers using analogue phone lines will use the KX-TEA308 or KX-TES824 analogue phone systems. If a business wants to start with analogue lines and upgrade to ISDN or VoIP Telephone lines then they should consider the KX-TDA15 or KX-TDA30 Digital Hypbrid Systems and start with the analogue trunk card, which can be swapped out later to an ISDN2e Trunk Line Card when the upgrade to ISDN Digital Telephohne Lines is required.
