The SAM2000G-12, SAM2000Q-12 and SAM2000-12 each have nine SHDSL bandwidth options; default
is 272 kbps. Distance capabilities at each bandwidth vary, dependent upon the type of line code being
utilized. Distances listed below assume the use of 26 American Wire Gauge (AWG) cable; connections
made with cable of a greater gauge will link up at greater distances. The ports on your module may not link
up if your cables are in poor condition or if cable distances are greater than the configured bandwidth will
support. Although it is sometimes possible for links to be achieved under such conditions, traffic quality
may be effected (e.g., packets may be dropped).
6.0 ADDITIONAL INFORMATION
6.1 Data Storage
Configuration backup is inherent in Net to Net Technologies IP DSLAMs. SAM2000G default
parameters remain in place unless changed via CLI, NMS or SNMP. Once changed, new
configurations are automatically recorded in both RAM and NVRAM.
6.1.1 Memory
6.1.1.1 Random Access Memory (RAM)
Data stored in SAM2000G RAM will be erased if the module is removed from your IP
DSLAM or if your IP DSLAM loses power.
6.1.1.2 Non-Volatile Random Access Memory (NVRAM)
Data stored in the NVRAM of your IP DSLAM's MUM will remain intact (even if your IP
DSLAM loses power) unless deliberately cleared or reconfigured.
6.1.2 Local Files
Management and interface module configurations can be saved on your PC, or local network,
both as a backup and/or for use as a template for future configurations, via the MUM in your
IP DSLAM. Management configurations and all interface module port configurations are saved
