Most phone lines sample at 8kHz, which means any signal beyond the 4kHz mark will be down sampled to the point of significant data loss and returned as noise, so yes, most phone lines only operate with 4kHz of bandwidth.

The telephone frequency range used for communication typically falls between 300 Hz to 3.4 kHz.
The term "5 4 on the AM radio dial" typically refers to a frequency of 540 kHz, which is the lower end of the AM radio band. In this context, "5 4" indicates the numbers 5 and 4, where 5 represents 500 kHz and 4 denotes 40 kHz, leading to a total of 540 kHz. This frequency is often used by various radio stations for broadcasting.
If 10 V input causes a frequency shift of 4 kHZ then 2,5v causes a freuency shift of 1 kHz. The input signal frequency of 1 kHz is irelevant.
You can use an in-line coupler to extend a telephone line.

No Not really sure what you are looking for in an answer but: A mobile telephone is a telephone, your Telephone connected to a land line is also a Telephone.
No the British Telephone line is not accessible from America. In order for it to work in America it has to be a 1 800 number. The British Telephone line is not a 1 800 number.
A tradition phone line has a sampling rate of 2400 baud but a baud is not a bit. A traditional phone line can transmit at close to 100 kbit/sec. To cleanly transmit a voice takes about 10 kbit/sec.
The first transcontinental telephone line was joined at Wendover, Utah, in 1915
First long-distance telephone line was created in 1877.
