ADSL Port Commands 3-5
Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce throughput but it makes the
connection more stable.

The numbers of milliseconds of interleave delay for downstream and upstream transmissions are listed. The total
output power of the transceiver varies with the length and line quality. The farther away the subscriber’s ADSL
modem or router is or the more interference there is on the line, the higher the power will be.
Current ATUR Information contains data acquired from the ATUR (ADSL Termination Unit – Remote),
in this case the subscriber’s ADSL modem or router, during negotiation/provisioning message interchanges. This
information can help in identifying the subscriber’s ADSL modem or router. The country code is from the Vendor
ID (g.994.1). The provider code includes the Vendor ID and Version Number obtained from Vendor ID fields
(g.994.1) or R-MSGS1(T1.413).
Information obtained prior to training to steady state transition will not be valid or will be old information. Annex
A refers to POTS.
