[. . . ] The disable port command forcibly disables the specified ADSL port. The factory default of all ports is disabled. A port must be enabled before data transmission can occur. An enabled but disconnected ADSL port generates more heat than an operating port. To minimize heat generation and to enhance reliability, remember to disable a port when it is not in use. 7. 5. 3 Syntax: Disable Ports Command 192. 168. 1. 1 adsl> disable ports The disable ports command forcibly disables all ADSL ports. The factory default of all ports is disabled. A port must be enabled before data transmission can occur. An enabled but disconnected ADSL port generates more heat than an operating port. To minimize heat generation and to enhance reliability, remember to disable a port when it is not in use.

The enable port command forcibly enables the specified ADSL port. The factory default of all ports is disabled. A port must be enabled before data transmission can occur. An enabled but disconnected ADSL port generates more heat than an operating port. To minimize heat generation and to enhance reliability, remember to disable a port when it is not in use. 7. 5. 5 Syntax: Enable Ports Command 192. 168. 1. 1 adsl> enable ports The enable ports command forcibly enables all ADSL ports.

The linedata command shows the line bit allocation of an ADSL port. 192. 168. 1. 1 adsl> linedata 7 DS carrier load: number of bits per symbol(tone): tone tone tone 0- 31: 32- 63: 64- 95: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 22 22 33 33 33 33 33 33 44 33 44 44 44 4 44 44 43 43 33 34 44 33 44 44 34 44 43 33 44 7-4 ADSL Commands IES-1000 User's Guide tone 96-127: 44 43 34 44 44 33 43 44 44 34 44 44 33 44 44 44 tone 128-159: 44 44 44 34 44 34 43 44 33 43 34 33 33 33 33 34 tone 160-191: 43 33 33 34 34 33 23 33 33 33 22 33 33 33 33 33 tone 192-223: 33 33 33 23 22 33 33 33 23 33 33 33 22 23 22 32 tone 224-255: 22 22 22 22 20 22 22 22 20 0 0 0 0 0 0 0 US carrier load: number of bits per symbol(tone) tone tone 0- 31: 32- 63: 0 0 0 0 0 0 0 0 2 34 55 77 88 89 99 99 99 98 88 87 0 0 0 0 0 0 0 0 0 0 0 0 The results can determine whether a given sub-carrier loop has sufficient margins to support ADSL transmission rates, and possibly to determine whether certain specific types of interference or line attenuation exist. The bit allocation contents are only valid when the link is up. 7. 5. 7 Syntax: Lineinfo Command 192. 168. 1. 1 adsl> lineinfo <port number> where <port number> = A port number, from 1 to 8. The lineinfo command shows the line operating values of an ADSL 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. If the DSL LED still turns on and off repeatedly, contact the distributor. 16. 4 Data Rate Table 16-4 Troubleshooting the SYNC-rate The SYNC-rate is not the same as the configured rate. STEPS 1 CORRECTIVE ACTION Connect the DSL modem or router directly to the DSL port of the network module using a different telephone wire. If the rates match, the regular phone wire quality may be limiting the speed to a certain rate (see section 6. 2). 2 Use the linerate command to check the subscriber's regular telephone wire (refer to Chapter 6 ).
