The major difference between DMT and CAP is:

Which modulation techniques are typical of ADSL, but not SDSL, SHDSL, or IDSL?

What ADSL DMT line rate requires (occupies) the most bandwidth on a telephone line?

In ADSL DMT systems, the highest downstream transmit power occurs at what rate/reach combinations?

A DSLAM is using Reed-Solomon forward error correction on a DMT DSL line. The DSL service is using TCP/IP over ATM over DSL. A high number of upstream RS uncorrected errors are occurring on the DSL line, as reported by the DSLAM in the following status message:DSL Statistics:Init Events: 2Transmitted Superframes: near end: 93681573 far end: 0Received Superframes:
near end: 93516422 far end: 0Corrected Superframes: near end: 142631 far end: 31571Uncorrected Superframes: near end: 191 far end: 1LOS Events: near end: 0 far end: 0LOF/RFI Events: near end: 0 far end: 0ES Events: near end: 5 far end: 1What is the result of the uncorrected errors?

What is not a valid service type between an 827 and a 6400?

A DSL subscriber reports that the CPE modem untrains and retrains several times each hour, but not at regular intervals. The subscriber has a DMT modem operating on 10 kft of #26 cable (3 km of 0.4 mm cable). The provisioned downstream rate is 2 mbps, and the provisioned upstream rate is 256 kbps. When the modem retrains, the downstream DSL may be as low as 512 kbps. Sometimes manually retraining the modem allows it to return to a 2 mbps line rate, and sometimes manually retraining the modem does not improve the DSL line rate. Which options would cause the intermittent train/untrain symptom as described? (multiple answer)

In DMT DSL transmission systems, what is the effect of turning off half of the available downstream carriers (tones)?

Which DSL modulation types allows line sharing (DSL and POTS voice on the same line)?
