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 CompactFlash 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).
Caution:
If your XSR has the 32 MByte Dual Inline Memory Module (DIMM) installed, you must
upgrade to the 64 MByte DIMM card to support ADSL operations. Refer to
“DIMM Upgrade for
ADSL Operation”
on page 2-6
