exist. To remove old and unwanted node information from this MIB, the operator must set the
“Clean” field to 1. The old node information will be removed. No further action is required.
Note if the node is valid, it will re-appear within seconds, even if it is cleared.
3.8.1.7 Setting the RF Rack/Chassis ID
transceptHubNodeRfTable.transceptHubNodeRfRackID
and
transceptHubNodeRfTable.transceptHubNodeRfChassisID
The Hub CPU may manage the I2C communications to the chassis that contains the RF
equipment belonging to some (1 – 2) of the tenants. The chassis and its rack are configured with
the Hub Node RF Rack ID and the Hub Node RF chassis ID fields. As not all Hub CPU’s
control RF chassis, this field is optional. If used, the allowable values are strings of 1 – 16
characters. The Hub configuration process will push these values to the Tenant Node MIB of the
CPU being configured as well as to the previously used locations in the BTS Connection MIB.
3.8.1.8 Setting The GPS Coordinates (Hubmaster Only)
(transceptHubNodeGpsCoordTable.transceptHubNodeGpsLongitude)
and
(transceptHubNodeGpsCoordTable.transceptHubNodeGpsLatitude)
For cases where a GPS receiver is not present and it is desired to manually enter the GPS
coordinates, the Hub Node MIB contains two MIB fields to configure the GPS longitude and
latitude settings. Since only the Hubmaster node in the Digivance CXD/NXD system contains a
GPS receiver, these MIB fields will not be used for Hub Slave nodes. The Digivance CXD/NXD
software (Hub Config Process) checks for the presence of a GPS on the Hubmaster node - if the
GPS is present, then the GPS longitude/latitude values will be automatically populated from the
Hubmaster Network Node MIB. If the GPS is not present, then the manually entered values will
be pushed to the Network Node MIB of the Hubmaster node.
When entering in the GPS longitude and latitude values, the format is a string representing
degrees as follows:
(-)xxx.yyyyyy, where the leading minus sign is optional.
3.8.2 Managing the RAN Node MIB
This MIB correlates RAN node IP addresses with their hostnames and physical locations. It also
documents where RF connections are made in each RAN. It resides solely at Hubmaster node. It
is comprised of the following elements:
