Digital Lines and Voice
A digital line or digital trunk is a type of line that carries voice and/or data by using digital sampling.
By converting analog signals to digital, these types of trunks allow for more information to be transferred over a single connection.
For instance, the maximum speed of an analog modem is 56 Kilobits per second (Kbps) while the maximum speed of a digital T1 line is 1.544 Megabits per second (Mbps) – almost 30 times more.
As tech advances, digital voice is fast becoming the phone line of choice for businesses large and small.
A voice-over-internet protocol, or VoIP, phone system connects your phone line directly to the internet and allows you to add or remove as needed.
Your system can work with standard equipment, or you can buy special phones with added features that can even connect to your cell phone so you can take office calls on the go.
Business owners prefer VoIP for its better connectivity and scalability. Calls made on digital business equipment are cloud-based, so you can make calls as long as you have a network connection and a connected device.
How does a digital telephone line work?
Digital phone use Time Division Multiplexing (TDM), a method of transmitting multiple digital signals over one communication media, to accommodate up to 24 voice conversations over one circuit. The most common digital telephone lines are T1 and Primary Rate Interface (PRI).
Distinguishing An Analog Vs Digital Line
Analog line, also referred to as POTS (Plain Old Telephone Service), support standard phones, fax machines, and modems. These are the lines typically found in small offices. The line is found in large, corporate phone systems or cellular.
Keep your business setup in mind
Small businesses come in all shapes and sizes, so there is no one-size-fits-all solution when it comes to setting up an ideal telephone system.
