Telephone Point Questions

hi,

can anyone advise the following :

if i want to have telephone jack in each bedroom,

is this normal telephone jack available when you subscribe to singtel fixed line only ?

how about if you subscribe to starhub or M1 and they give you a modem which enables you to connect your telephone to the modem and give you cable digital voice,

how to do the connection from this to the telephone network which you have set up in each of the rooms ?

have anyone encounter this problem and solve it ? can share your solution ?
