Security device

The NTDK20 SSC card in each MG 1000S must contain a NTDK57DA Security device, a remote dongle (NT_Rem) which is keyed to match the NTDK57AA Security device on the Call Server and a standard dongle (NT_STD). This maintains the requirement of a single keycode for each system. Refer to Figure 167 on page 801 for the location of the device.

This security scheme provides the following:

•enables the system to operate as a single system when all links are up.

•enables the MG 1000S to continue operating with its existing configuration in the event of a failure of the Call Server, or the failure of the link to the Call Server from the MG 1000S.

•prevents users from configuring or using unauthorized TNs or features.

The MG 1000S security device provides the following capabilities for the MG 1000S:

•System software can be installed but no calls can be processed or features activated until communication with the Call Server has been established and a match between the security ID of the Call Server and the

MG 1000S has been confirmed.

•System software can be upgraded.

Note: Local data dump, LD 43 commands, and LD 143 commands are not permitted.
