5.0 BANDWIDTH AND DISTANCE
N
Parameters common to all interface module models are defined in the CLI, NMS and SNMP Management User Guides.
OTE
Bandwidth, however, is specific to the SAM2000GV-12, SAM2000QV-12 and SAM2000-12.
The SAM2000GV-12, SAM2000QV-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. SAM2000GV 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 SAM2000GV 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.
