Black Box Explains...Consumer-Grade vs. Commercial-Grade Phone-Line Managers.
The difference between consumer- and commercial-grade phone-line managers is more than just a matter of size. The number of ports, phone lines, and connected communications equipment possible with commercial-grade devices is larger—as many as 24 devices on 8 lines!
But flexibility is the key factor. The extra features, like programmability and built-in surge protection, set commercial line managers apart. Some models feature connections for three devices to each phone line, available on a first-come, first-served basis. Others can provide shared connections for an entire business, saving thousands of dollars per year.
And data-collection transmissions can also be run on the same lines used for voice calls, so remote business sites can transmit information for centralized data collection over one phone line—no dedicated line necessary.
