LS-108N Remote Unit

The LS-108N is typically located at the remote end (eg. substation) and connects between the phone line and multiple (up to eight) dial-up SCADA equipment such as IEDs and meters. It can be installed into existing dial up circuits with no change to the existing dial up parameters.
It logs activity information including time / date, identity of calling Unit and duration of call. This information is recorded regardless if the call is completed or not.
Each LINESHIELD Unit is factory configured with a unique serial number and customer ID.
The LS-108N is the same as the LINESHIELD LS-108 unit except that it does not perform authentication and authorization when connected to the phone line. If the latter functions are required in the future, the LS-108N is field upgradeable to the LS-108 version.
For larger systems, a Central Administration System (CAS) can be used to automatically gather individual LS-108N records. The call authentication and authorization part of CAS would of course not be enabled.
