The NVRAM does not require a back up battery so that you can eliminate the threat of data loss due to a dead battery, as well as avoid hardware damage due to electrolyte leakage.
2.10 Factory Default Profile (FDP)
The FDP is the default configuration profile stored in your modem
To display the FDP, use command &F to place the profile into the active configuration area (ACA), then issue AT&V. Note that some modems may have more than one
2.11 Stored Configuration Profile (SCP)
The SCP is the configuration profile stored in the NVRAM of the modem to be retrieved for later use.
Initially the factory sets the SCPs identically to the FDPs. To view all the SCP configurations, issue command &V. note that once an SCP is selected and loaded into ACA, it becomes the major SCP and provides the control characteristics of the modem.
If you hav edited the ACA and wish to write it to an SCP, issue a &W command. The modified configuration profile overwrites the original SCP and becomes the new SCP.
For information on the SCPs of your particular modem, refer to your Getting Started manual.
2.12 Major Stored Configuration Profile (Major SCP)
The major SCP is the SCP that is loaded into the ACA each time the modem is turned on or reset by ATZ. To designate an SCP as the major SCP, issue &Y followed by the SCP number. For example, issuing &Y1 designates SCP1 as the major SCP.
2.13 Active Configuration Area (ACA)
The ACA is a portion of the
