Telephone companies are replacing older,analog lines with digital lines because?

Question

A-data is transmitted more quickly over digital lines
B-digital lines are less expensive
C-computers can now be equipped with modems to translate transmissions
D-wireless transmissions can be used only for short distances

Answer 1

A: No. It's more like: more information can be delivered reliably over digital fiber optic lines than analog copper lines. Not any quicker.

B: No, in fact, it's costing the local carriers an awful lot of money to lay fiber to the home, much more than copper.

C: Not relevant. Modem are use to translate from one transmission medium to another. Modem = modulator-demodulator. You already did that when you had dialup (the screeching noises). Now we do it for DSL, cable, and now FiOS.

D: Not relevant. The local phone companies won't and can't compete w/ the wireless carriers in that realm.

The real reason: They need to compete w/ the cable companies and satellite TV companies in providing services to homes and businesses. Local telephone service and routing LD calls into and out of their networks won't cut it long term. The big services: Telephone, Internet Access, TV. The way to do it: run high bandwidth cabling to the home (fiber optic cable) and provide these services via IP. That's why Verizon et al is rollng out VoIP, Internet, and IP TV services to residents w/ FiOS.

Answer 2

FIber to the prem is the newest trend - A single cable that will carry TV service, Phone service and also Internet Service that is much faster than your DSL service.
