Chapter 3 Configuration The configuration software allows you to adjust and monitor the operating parameters of the media converter.
Configuration Starting a Configuration Session Downloading Software Updates In order to configure and manage your AT-MC601 and AT-MC602 VDSL network extenders, you need to download a copy of the configuration software onto the computers you will use to manage the units. The ATS57 configuration software is included on the Documentation CD provided with the units. New releases of the AT-S57 configuration software are available from the Allied Telesyn Web site at www.alliedtelesyn.
AT-MC601, AT-MC602 Installation and User’s Guide (For Use with AT-MCR12 Only) Opening the Configuration Software Open the configuration software by double-clicking the “ATS57” application icon, as you would with any other software program. The ATMC60x Configurator pop-up will appear, as shown in Figure 19.
Configuration Configuring the Provider Unit After performing the procedure described in the previous section, ”Starting a Configuration Session” on page 36, if you are connected to the Provider unit, the AT-MC60x Configurator menu will appear. The Configurator bar at the top of the menu indicates whether or not the Provider unit has established an Ethernet link by displaying [link DOWN] or [link UP] in brackets.
AT-MC601, AT-MC602 Installation and User’s Guide (For Use with AT-MCR12 Only) The parameters on the Configuration screen are described below. Upstream/Downstream The upstream and downstream data transfer rate. ❑ Actual (Mbps) Displays the actual data transfer rate on the line. The software automatically detects this speed. ❑ Min (Mbps) Allows you to adapt the data transfer rate by setting a minimum speed. ❑ Max (Mbps) Allows you to adapt the data transfer rate by setting a maximum speed.
Configuration The Configuration Saved pop-up shown in Figure 22 will appear when the set rate or the highest possible rate has been achieved. Figure 22 Configuration Saved An unsuccessful configuration attempt may include the following status reports: Loading defaults Can’t read link status Done These negative status reports may also be accompanied by error message pop-ups. Error messages are explained in ”Troubleshooting” on page 47.
AT-MC601, AT-MC602 Installation and User’s Guide (For Use with AT-MCR12 Only) VDSL Status To view the VDSL Status screen, click on the VDSL Status tab at the top of the menu. The VDSL Status screen is displayed in Figure 23. Figure 23 VDSL Status The parameters on the VDSL Status screen are described below. These parameters are for viewing and monitoring purposes only. They cannot be changed manually. SNR of Received Signal The Signal-to-Noise Ratio on the VDSL line, measured in decibels.
Configuration Reduced Constellation Link A lesser QAM constellation, causing reduced line rates. If the full constellation rate cannot be achieved because the received SNR is too low, then a reduced constellation link can be established and the software can automatically configure the Subscriber unit parameters. TC Synchronized Transmission convergence is synchronized. Ethernet Encapsulation Sync The process of encapsulating packets into frames at the VDSL link level is synchronized.
AT-MC601, AT-MC602 Installation and User’s Guide (For Use with AT-MCR12 Only) Ethernet Status To view the Ethernet Status screen, click on the Ethernet Status tab at the top of the menu. The Ethernet Status screen is displayed in Figure 24. Figure 24 Ethernet Status The parameters on the Ethernet Status screen are described below. TxRx Counters The data fields in this section indicate the number and type of frames that have been transmitted and received via the Ethernet link.
Configuration Stop/Start This button allows you to pause counting. When you press Stop, the counters remain at their present values. When you press Start, the counters continue adding to the values already recorded by the software. Local/Remote Select Local to view the parameters for the Provider unit. Select Remote to view the parameters for the Subscriber unit. The Remote option will only be available when an active link has been established.
AT-MC601, AT-MC602 Installation and User’s Guide (For Use with AT-MCR12 Only) Configuring the Subscriber Unit In rare instances, you may need to use the configuration software on the Subscriber unit to attempt link recovery. If the configuration software detects a problem with the Subscriber unit while you are connected to the Provider unit, it will prompt you to use the software on the Subscriber unit by displaying a pop-up error message.
Configuration Install The Install mode enables a watchdog timer to monitor the link attempt process. If the network extenders are not able to establish a link using the parameters you set on the Provider unit within a reasonable amount of time, a timeout will occur. After a timeout, the default configuration parameters will be used to establish a link with the highest possible speed. The default configuration parameters start at 0.94 Mbps upstream and downstream with negotiation set from Low -> High.
Chapter 4 Troubleshooting This chapter contains information on how to troubleshoot the AT-MC601 and AT-MC602 network extenders in the event a problem occurs. Note If after following the instructions in this chapter you are unable to resolve the problem, contact Allied Telesyn Technical Support for assistance.

Troubleshooting LEDs Check the PWR LED on the front of the network extender. If the LED is OFF, indicating that the network extender is not receiving power, do the following: ❑ If the network extender is inserted in the AT-MCR12 chassis, make sure that the power cord is securely connected to the power source and to the power connector on the back panel of the AT-MCR12 chassis.
AT-MC601, AT-MC602 Installation and User’s Guide (For Use with AT-MCR12 Only) Error Messages When using the configuration software, you may encounter the following error messages: ❑ “No answer from device,” as shown in Figure 27 Figure 27 No Answer Error Message This error message may occur when your computer is not responding, in which case you should re-start your computer and try again. ❑ “Communication error: the program will be closed.
Troubleshooting ❑ “P side must be connected to start this procedure” or “S side must be connected to start this procedure” These error messages occur when the management cable is connected to the wrong unit for the procedure you are trying to perform.This could happen if you switch the management cable between the units without closing the software window. Simply switch the management cable to the other unit to correct the problem.
