3Com Router Module Guide Chapter 3 Multifunctional Interface Modules3-47Step 1: Insert one end of a T1 cable into the RJ-45 connector on the T1 or T1-Fmodule;Step 2: Connect the other end of the cable to the device to be connected:z directly if the cable is long enough; orz after extending the cable if it is not long enough, as shown in the following figure:Router DDN, etcRJ45Network interface connectorRJ45 Straight-through network cableRJ45shielding network cable)T1 cable (100-ohm straight-throughFigure 3-52 Extending a T1 cableStep 3: Power on the Router, and check the corresponding LED READY on the frontpanel of the router for the slot: ON means that the MIM is operating normally and OFFmeans that the POST of the MIM has failed. In the latter case, please contact youragent;Step 4: Check the behavior of the LINK LED on the T1 or T1-F panel. It is OFF whenthe line is faulty and signal is Off.3.11 ROUTER 1-PORT ADSL OVER POTS MIM3.11.1 IntroductionROUTER 1-PORT ADSL OVER POTS MIM/, the 1-/2-port ADSL over PSTN interfacecard, allows a LAN subscriber to connect to the digital subscriber's loop accessmultiplexer (DSLAM) at the central office over a regular analog subscriber line ortelephone line. Thus, the subscriber can access the ATM/IP backbone or the Internetto enjoy services such as high-speed data communication and video on demand(VoD).ADSL transmits data in the high frequency band above 26 kHz. Therefore, it canprovide services without interfering with the voice service being provided in the lowfrequency band (0 to 4 kHz) on the same line. It provides downlink rates in the range32 kbps to 8 Mbps and uplink rates in the range 32 kbps to 1 Mbps.The ADSL interface cards provide these functions:z Manual ADSL line activation and deactivation, supporting SAR loopback forconvenient fault isolation.z Interface standards of G. DMT, G. Lite, and T1.413, auto-sensing.z Trellis coding (except for G. Lite) on ADSL interfaces, enhancing stability of ADSLconnections.
