However, when an Option 11C Mini chassis is used, the NTDK97 Mini System Controller (MSC) card is replaced with an NTDK20 Small System Controller (SSC) card and an appropriate IP Expansion daughterboard. Option 11C and Option 11C Mini software is stored in various areas of the NTDK20 SSC and NTDK97 MSC cards. In terms of customer data, there

By invoking one of the several data dump commands in the overlay, the user is ensured that at least one backup copy of configuration data exists in a location other than DRAM (Refer to Table 1).

This storage device can be an IBM- type PC or Macintosh-type computer, running an Option11C software feature called “Customer Configuration Backup and Restore” (CCBR). Through the use of LD 143 and the CCBR feature, the user can transfer customer records between the SSC or MSC’

There are four possible areas of where a backup of configuration data can be restored from — the secondary primary database, the backup flash drive, the PCMCIA drive, or an external computer hard-drive. (Refer to Table 2 for a description of the commands used to restore backup data to

Pre-programmed data is not mandatory for software installation. In fact, the NTDK20 or the NTDK97, can be programmed with the minimum number of files to allow the Option 11C and 11C Mini to operate. During start-up, the Software Installation Program is automatically invoked. The Option 11C or Option 11C Mini, loads system data from the NTDK2

Page 20 of 544 Memory, Storage and CPU capacity Telephone models simplify telephone installation. During telephone activation, the telephone prompts you to accept a default model. If a model is chosen, all keys are automatically assigned a feature and no further key programming is required. (The extension number is also predefined using the default numbering plan.) If you do not want to accept the default model, you can create other models by following the procedures in Chapter 19 of the Op
