[. . . ] Type this command to show the VDSL auto upgrade status (without "on" or "off") or turn on/off auto upgrade. When auto upgrade is on, the P841C will check the subscriber's modem VDSL version and automatically upgrade it if it is an earlier version than the P841C's. Ethernet-related Commands enet status enet clear Type this command to display P841C and the subscriber's VDSL modem's Ethernet statistics (if link is up). Type this command to clear P841C and the subscriber's VDSL modem's Ethernet statistics (if link is up). vdsl reset vdsl reconnect vdsl status vdsl clear vdsl debug [on|off] vdsl monitor [on|off] vdsl show vdsl write (lt|nt) addr value vdsl mode (mode) vdsl active [on|off] vdsl autoupg [on|off] 3-4 Configuring the P841C P841C Central-Side VDSL Modem Table 3-1 P841C Help Commands FIELD enet speed (lt|nt) (speed) enet fctrl (lt|nt) [on|off] enet monitor [on|off] DESCRIPTION Type this command to set the Ethernet port speed of the P841C (you must type "lt") or P841 ("nt"). Type this command to set the Ethernet port full duplex flow control of the P841C (you must type "lt") or P841 ("nt"). P841C full duplex flow control is displayed if you just type "enet fctrl". Display P841C and the subscriber's VDSL modem's Ethernet statistics (if link is up) if this flag is on. 3. 4. 4 Sys Status Command Type sys to display the following system status parameters. firmware version = V1. 00(DH. 0)b3 | 3/26/2002 VDSL modem code version = 0x50 sys uptime = 27782 ms (0:00:27. 782) Figure 3-7 Sys Status Command Table 3-2 Sys Status Command FIELD firmware version vdsl modem code version sys uptime DESCRIPTION This field shows the P841C firmware version and the date it was created. This field displays in milliseconds (and hours, minutes, seconds) how long the system has been up. 3. 4. 5 Firmware Upgrade Command fwupgrade Follow these steps for a successful firmware upgrade. Step 1. Type fwupgrade to begin the firmware upgrade process via XMODEM. P841C>fwupgrade This operation will overwrite the old firmware!Continue?(Y/N) Figure 3-8 Upgrading Firmware First Warning Step 2. You now see the next screen warning you not to abort the upload process after the Xmodem file transfer begins. If you want to quit the firmware upgrade process and you have NOT YET started the file transfer process (using a Terminal emulation program), then restart the P841C now to exit. Configuring the P841C 3-5 P841C Central-Side VDSL Modem You MUST NOT abort this operation after XMODEM data transfer begins. Restart your device before XMODEM transfer begins to quit the upgrade process. Figure 3-9 Upgrade Firmware Last Warning Step 4. Launch your terminal emulation program (see next example). You should have already downloaded the firmware and unzipped it on your computer. DO NOT interrupt it ­ wait until the file transfer process finishes. If you abort the upload after the transfer begins, your device will be seriously damaged! Example Xmodem Firmware Upload Using HyperTerminal Click Transfer, then Send File to display the following screen. Type the firmware file's location, or click Browse to look for it. The firmware file has a "bin" extension. Choose the Xmodem protocol. Finally, click Send. Figure 3-10 Example Xmodem Upload 3-6 Configuring the P841C P841C Central-Side VDSL Modem Chapter 4 VDSL- Related Commands This chapter shows you how to configure VDSL using Commands. 4. 1 Introduction VDSL-related commands supported by the P841C are shown in Table 3-1. The default values for the following VDSL parameters are: Table 4-1 VDSL Default Values VDSL PARAMETER VDSL Mode VDSL Active VDSL Upstream Rate VDSL Downstream Rate On 12Mbps 12Mbps DEFAULT VALUE 0 = 10BaseS mode 4. 1. 1 VDSL Mode Command vdsl mode (mode) This command displays the VDSL mode if you don't type a mode and sets it if you do. Use the "vdsl reset" or "vdsl recon" command to make VDSL reconnect after you set the mode; it does not do this automatically. The modes are listed in the next table. P841C>vdsl mode vdsl mode: 10BaseS(0) Figure 4-1 VDSL Mode Table 4-2 VDSL Mode MODE NUMBER 0 1 2 MODE TYPE 10BaseS mode ANSI Mode (ANSI/ETSI Band Plan 998) ETSI Mode (ETSI Band Plan 997) The band plan is different for each mode even though the speed may be the same. The following table summarizes transmission rates and frequency ranges for each VDSL mode supported by the P841C.

Rates vary according to VDSL mode selected ­ see Table 4-4 and section 4. 1. 1. Upstream Rates vdsl uprate [uprate] "uprate" is an integer from 0 to 4 as defined in the next table. This command sets the upstream VDSL rate if you set a rate and displays the rate if you don't. If you set a new rate, you must use "vdsl reset" or "vdsl reconnect" command to reconnect. P841C>vdsl uprate vdsl upstream rate: 1562500 bps (0) Figure 4-2 VDSL Upstream Rate Downstream Rates vdsl downrate [downrate] "downrate" is an integer from 0 to 4 defined in the next table.
