[. . . ] For example, you could set up different profiles for different kinds of accounts (say economy, standard and premium). Assign the appropriate profile to an ADSL port and it takes care of a large part of the port's configuration. You still get to individually enable or disable each port, as well as configure its encapsulation type, multiplexing mode, VPI, VCI and operational mode. See later in this chapter for how to configure profiles. 7. 3 Configured Vs. Actual Rate You configure the maximum rate of an individual ADSL port by modifying its profile (see the set profile command) or assigning the port to a different profile (see the set port command). However, due to noise and other factors on the line, the actual rate may not reach the maximum that you specify. ADSL Commands 7-1 IES-1000 User's Guide Even though you can specify arbitrary numbers in the set profile command, the actual rate is always a multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32 Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps. Note that when you configure an ADSL port, the upstream rate must be less than or equal to the downstream rate. Note also that the list port command displays the configured parameters of the ADSL port, while the show port command displays the actual rates. 7. 4 Default Settings The default profile always exists and all of the ADSL ports belong to it when the AAM1008 is shipped. The default profile's maximum downstream rate can only be obtained when using the G. dmt standard. Configure a profile with a maximum downstream rate of 1536 Kbps or less for use with G. lite. 7. 4. 1 · · Default Profile Settings The following are the settings of the default profile.

[. . . ] If you cannot ping, connect a DSL modem to a DSL port (that is known to work) on the same network module. If the DSL modem or router works with a different DSL port, there may be a problem with the original port. Contact the distributor. 2 3 4 5 6 7 If using a different port does not work, try a different DSL modem or router with the original port. Troubleshooting 16-1 IES-1000 User's Guide 16. 3 SHDSL or ADSL LED(s) Turn On and Off Table 16-3 Troubleshooting a Non-Constant DSL LED An SHDSL or ADSL LED turns on and off intermittently. STEPS 1 2 CORRECTIVE ACTION Use the lineinfo command with G. SHDSL (refer to 6. 6. 6) or the linerate command with ADSL (refer to 7. 5. 9) to check the subscriber's telephone wiring. Connect a DSL modem directly to the DSL port of the network module using a different telephone wire. [. . . ]
