System Coordinates
The system coordinates is the Alcatel-Lucent Chassis MIB tmnxChassisCoordinates object. This
text string indicates the Global Positioning System (GPS) coordinates of the location of the
chassis.
Two-dimensional GPS positioning offers latitude and longitude information as a four dimensional
vector:
where direction is one of the four basic values: N, S, W, E, hours ranges from 0 to 180 (for
latitude) and 0 to 90 for longitude, and minutes and seconds range from 0 to 60.
<W, 122, 56, 89> is an example of longitude and <N, 85, 66, 43> is an example of latitude.
System coordinates can be expressed in different notations, examples include:
•
N 45 58 23, W 34 56 12
• N37 37' 00 latitude, W122 22' 00 longitude
• N36*39.246' W121*40.121
The system coordinates can be any ASCII printable text string up to 80 characters.
Naming Objects
It is discouraged to configure named objects with a name that starts with “_tmnx_” and with “_” in
general.
Common Language Location Identifier
A Common Language Location Identifier (CLLI) code string for the device is an 11-character
standardized geographic identifier that uniquely identifies the geographic location of places and
certain functional categories of equipment unique to the telecommunications industry. The CLLI
code is stored in the Alcatel-Lucent Chassis MIB tmnxChassisCLLICode object.
The CLLI code can be any ASCII printable text string of up to 11 characters.
