What is line speed
Line Speed is the speed of data transmission between your modem and your ISP. ADSL1 services allow upto a theoretical maximum of 8000/1000kbps, ADSL2 has a theoretical maximum of 12000/1000kbps and ADSL2+ has a theoretical maximum of 24000/1000kbps with ADSL2+ (Annex M) having a higher upload maximum of 24000/2500kbps.
Factors Affecting Line Speed
- the length of the telephone wire from your premises to the telephone exchange - this is always higher than the distance 'as the crow flies' (The longer the distance, the lower the synch speed).
- the number and type of other services being used by other customers over telephone lines running close to yours.
- the configuration and line quality of the copper wire pair between the telephone exchange and your premises.
- electrical interference from outside sources (such as electric motors).
- the configuration of the phone wiring within your premises (i.e. use a central splitter for optimal performance).
- the software configuration and applications on your computer (in particular how it uses the uplink back to the exchange).
- your ADSL hardware and its capabilities (some devices run out of CPU power below the configured line synch speed at ADSL2+ data rates).
- the capacity of, load on, and access data rate of the destination host computer or server that you are accessing.
