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).
