1-Port ADSL NIM Card Port

The XSR’s Asymmetric Digital Subscriber Line (ADSL) NIM card, as shown in Figure A-23, provides 1 WAN port on an ADSL over POTS (Annex A/C) or ISDN (Annex B) line with a 6-pin RJ-11 connector. The ADSL NIM supports both G.dmt and G.lite standards. ADSL NIMs are shipped with a CompactFlash card containing DSP firmware. This driver software copies the Flash file into host memory where it provides on-demand use by the DSP.

Note: The XSR supports only one ADSL card type at a time, so multiply-installed card types must be similar.

The XSR supports only one ADSL card type at a time, so multiply-installed card types must be similar.

The LEDs behave as follows: LED 1 - Status - When OFF, the line is down; when ON; the line has ended “training” or synchronization with the remote DSLAM device and is operational; when Flashing, the line is in training mode; LED 2 - Data - When flashing, traffic is active.
