Chapter 52 ADSL Commands
The atuc information fields show data acquired from the ATUC (ADSL Termination Unit
– Central), in this case
–Remote), in this case the subscriber’s DSL modem or router, during negotiation/provisioning message interchanges. This information can help in identifying the subscriber’s DSL modem or router.
The vendor ID, vendor version number and product serial number are obtained from vendor ID fields (see
Syntax:
ras> statistics adsl lineperf <portlist>
where
<portlist> | = You can specify a single DSL port <1>, all DSL ports <*> or |
| a list of DSL ports <1,3,5>. You can also include a range of |
| ports <1,5,6~10>. |
This command shows the line performance counters of a DSL port.
An example is shown next.

These counters display line performance data that has been accumulated since the system started. In the list above the definitions of near end/far end will always be relative to the ATU- C (ADSL Termination
A block is a set of consecutive bits associated with the path; each bit belongs to one and only one block. Consecutive bits may not be contiguous in time.
