| Downstream The maximum speed between the Provider and the Customer. For ADSL rate adaptive services, this speed depends on the characteristics of the telephone cable | 20Mb/s | 7Mb/s | 7Mb/s | 4Mb/s | 2Mb/s | 2Mb/s | 1,2Mb/s | 640kb/s |
| Upstream The maximum speed between the Customer and the Provider. For ADSL rate adaptive services, this speed depends on the characteristics of the telephone cable. The upstream is more sensitive to the quality of copper lines than downstream | 1Mb/s | 512kb/s | 384kb/s | 512kb/s | 512kb/s | 256kb/s | 512kb/s | 256kb/s |
| Committed bandwidthIt's the minimum guaranteed bandwidth. For ADSL rate adaptive profiles it depends on the speed of the initial handshaking (engagement), which in some cases may be lower. | 1M - 512k | 1M - 300k | 1M - 200k | 1M - 300k | 1M - 300k | 1M - 200k | 800k - 200k | 400k - 200k |
| Rate adaptive The term only applies to ADSL and indicates the tolerance in terms of downstream and upstream speed during installation. Due to the possible installation of systems generating interference on the same central, the performance of a rate adaptive line can change over time. The intervals are expressed in kb/s |
