Figure 2-13 Connecting ADSL Connector

A CompactFlash card is provided with the XSR ADSL NIM. It is loaded with the Digital Signal

Processing (DSP) firmware (

adsl.fls) required to communicate with your DSLAM. When

inserted into the Compact Flash slot - upon first configuring an ATM interface - the XSR’s ADSL

driver will copy

adsl.fls into host memory where it will remain available for use on demand. Be

aware that if all ATM interfaces are deleted,

adsl.fls must be recopied into Flash.

Note: The XSR supports one installed ADSL NIM card type at a time (multiple installed cards must

be of the same type).
