There are three sections to this FAQ: Section 1 Commands for accessing the STH line statistics Section 2 Screen capture of required commands Section 3 General line statistic information To obtain line statistics from the Alcatel STH modem, a command-line interface (CLI) via telnet must be utilized. Important Note: If you are using a separate router in conjunction with your modem must connect the modem directly to a single PC in order to access the modem's interface. Additionally, to access the data the modem must be in Expert (Trace & Debug) mode. You must have the challenge code before you can proceed with this FAQ. Please reference the STH Expert Mode FAQ to obtain the challenge code or if you are unable to telnet into the STH. If all the information and procedures listed above are too complicated or you simply don't want the hassle there is a third party program called Alcatool that provides a GUI alternative available here.

Anything over 2,000Kbps is considered good. The higher the number the better. Used Line Rate Your Used ATM Rate (actual service rate) plus bandwidth to cover the overhead and provisioning of the service. Fast Used ATM Rate Actual bandwidth at which your service has been provisioned. The actual number can vary a little depending how you are physically serviced. If there is a number here that also means your connection is "fastpathed". Interleaved Used ATM Rate Actual bandwidth at which your service has been provisioned. The actual number can vary a little depending how you are physically serviced. If there is a number here that also means your connection is "interleaved". Relative Capacity Occupation Percentage of your overall available bandwidth used to obtain your service ATM rate. For example; if your max line synch rate was 5888Kbps and you were provisioned on a 1472Kbps service you would be using 25% capacity. 1472/5888=25% capacity. The lower the relative capacity the better, but you can still get maximum speeds (although a less stable connection) even with a very high relative capacity. In other words you could be synching at 1472Kbps with 98% relative capacity and achieve maximum speeds, but you may experience more disconnects. Noise Margin (AKA Signal to Noise Ratio) Relative strength of the DSL signal to Noise ratio. 6dB is the lowest dB manufactures specify for modem to be able to synch. In some instances interleaving can help raise the noise margin to an acceptable level. The higher the number the better for this measurement. Line Attenuation Measure of how much the signal has degraded between the DSLAM and the modem. Maximum signal loss recommendation is usually about 60dB. The lower the dB the better for this measurement. Output Power How much power modem (upstream) or DSLAM (downstream) is using. Maximum recommended is about 15dB. The lower the power the better for this measurement. __________________________________________________________ Andy Houtz Feedback received on this FAQ entry:
