Description and Installation
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 170 on
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.
