The current deployment of ADSL lines grows up day by day. Next application is VoIP where the user receives an Integrated Access Device to make everything and Video over IP is also coming. For those kind of application a normal ‘sniffer’ over Ethernet is practically un-useable!
The solution to this problem is the new xDSL Monitor. The xDSL Monitor provides a cost-effective in-line xDSL Protocol Analyzer for trouble-shooting xDSL line installations and developing and testing xDSL equipment. With the optional 3Play Quality pack you can improve your testing with VoIP and IPTV services quality analysis for a full 3Play deployment.
This is an xDSL monitor to be inserted between the Central Office (DSLAM side) and the customer premise (CPE side). The plug and play monitor follows the xDSL Monitor family policy where an hardware probe captures the relevant details of the line and the optional software package decodes it. All the packets are stored with its timestamp for later analysis, if the external pc is connected, it is possible to make a live capture and analysis of the traffic. The xDSL Monitor plugs directly into the xDSL line to be analyzed, connected in circuit between the DSL Access Multiplexer (DSLAM) and an xDSL modem (CPE). The xDSL Monitor provides a powerful protocol analysis capability for use in capturing, decoding and displaying all the AAL5 packets that are transmitted in both directions across an xDSL line. Its features make it a device smart to use and an ideal companion for the xDSL technicians, called for troubleshooting or SLA maintaining.
In fact the ATU-R emulation provides a valid aid to exclude possible problems of the user's modem while the xDSL link operation data gives a detailed overview on the present status of the connection and allow an aimed and quick intervention. The link conditions can be furthermore monitored through the graphical display of the DMT bits per tone allocation in order to discover possible noises or interference signals.
The xDSL Monitor consists of a Probe chassis with one plug for Test Interface Modules (TIM) emulating the CPE and one for the TIM simulating the DSLAM. Each TIM module support different technologies and are used for the connection from the CPE and the DSLAM. The Probe captures all the traffic on the line for both downstream and upstream directions and stores it on its own memory and it sends the data to a connected PC for a long term recording via standard 10/100BT Ethernet. The embedded processor cards feature an advanced communications microcontroller, ROM, RAM and FLASH memory. The user interface for this system is established over the Recording PC via the Ethernet connection. A simple, intuitive Protocol Analysis Graphical User Interface (GUI) runs on the Recording PC for analysis and quick setup of xDSL line and ATM PVCs parameters.
