18.3 xDSL Performance Screen

These counters display line performance data that has been accumulated since the

system started. The definitions of near end/far end are always relative to the ATU-

C (ADSL Termination Unit-Central Office). ATU-C refers to downstream traffic from

the IES-1248-51V. ATU-R (ADSL Termination Unit-Remote) refers to upstream

traffic from the subscriber.

Port Name This section displays the name of the ADSL port.

Bit Allocation “DS carrier load” displays the number of bits transmitted per DMT

tone for the downstream channel (from the IES-1248-51V to the

subscriber’s DSL modem or router).

“US carrier load” displays the number of bits received per DMT tone

for the upstream channel (from the subscriber’s DSL modem or router

to the IES-1248-51V).
