This application is a continuation of U.S. application Ser. No. 14/577,769, filed Dec. 19, 2014, which is a continuation of U.S. application Ser. No. 14/153,282, filed Jan. 13, 2014, now U.S. Pat. No. 8,929,423, which is a continuation of U.S. application Ser. No. 13/004,254, filed Jan. 11, 2011, now U.S. Pat. No. 8,634,449, which is a continuation of Ser.

No. 7,835,430, which is a continuation of U.S. application Ser. No. 10/619,691, filed Jul. 16, 2003, now U.S. Pat. No. 7,570,686, which is a continuation of U.S. application Ser. No. 09/755,173, filed Jan. 8, 2001, now U.S. Pat. No. 6,658,052, which claims the benefit of and priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 60/224,308, filed Aug. 10, 2000 entitled “Characterization of transmission lines using broadband signals in a multi-carrier DSL system,” and U.S. Provisional Application No. 60/174,865, filed Jan. 7, 2000 entitled “Multicarrier Modulation System with Remote Diagnostic Transmission Mode”, each of which are incorporated herein by reference in their entirety.
The diagnostic and test information can include, for example, but is not limited to, signal to noise ratio information, equalizer information, programmable gain setting information, bit allocation information, transmitted and received power information, margin information, status and rate information, telephone line condition information, such as the length of the line, the number and location of bridged taps, a wire gauge, or the like, or any other known or later developed diagnostic or test information that may be appropriate for the particular communications environment. For example, the exchanged diagnostic and test information can be directed toward specific limitations of the modems, to information relating to the modem installation and deployment environment, or to other diagnostic and test information that can, for example, be determined as needed which may aid in evaluating the cause of a specific failure or problem. Alternatively, the diagnostic and test information can include the loop length and bridged tap length estimations as discussed in U.S. patent application Ser. No. 09/755,172, now U.S. Pat. No. 6,865,221, filed herewith and incorporated herein by reference in its entirety.
While the exemplary embodiment illustrated in FIG. 1 shows the diagnostic link system 100 for an embodiment in which the remote terminal modem 300 is communicating test and diagnostic information to the central office 200, it is to be appreciated that the various components of the diagnostic link system can be rearranged such that the diagnostic and test information can be forwarded from the central office 200 to the remote terminal modem 300, or, alternatively, such that both modems can send and receive diagnostic and/or test information. Furthermore, it is to be appreciated, that the components of the diagnostic link system 100 can be located at various locations within a distributed network, such as the POTS network, or other comparable telecommunications network. Thus, it should be appreciated that the components of the diagnostic link system 100 can be combined into one device for respectively transmitting, receiving, or transmitting and receiving diagnostic and/or test information. As will be appreciated from the following description, and for reasons of computational efficiency, the components of the diagnostic link system 100 can be arranged at any location within a telecommunications network and/or modem without affecting the operation of the system.

13. The device of claim 8, wherein the multicarrier transceiver is further operable to receive power information associated with the remote receiving device.
14. The device of claim 8, wherein the multicarrier transceiver is further operable to receive gain setting information associated with the remote receiving device.
15. A device operable to transmit channel measurement information, comprising:
wherein the multicarrier transceiver is further operable to retransmit a message with customized information in response to the message not being successfully received by a remote receiving device.
16. The device of claim 15, wherein the multicarrier transceiver is further operable to receive a second message that causes the multicarrier transceiver to transmit the message that includes the channel measurement information.
17. The device of claim 15, wherein the wideband communication channel is comprised of a plurality of discrete frequency carriers.
18. The device of claim 15, wherein the message further conveys status information associated with the multicarrier transceiver.
19. The device of claim 15, wherein the multicarrier transceiver is further operable to receive data rate information associated with the wideband communication channel.
