• The Tenant ID sub-string is comprised of four particular pieces of information: Tenant
Name, BTS ID, BTS Sector, and Tenant Band. These four pieces of information form
the Tenant ID sub-string, where each piece of information is delimited by a single
character (currently a colon ":").
• The IP Address sub-string indicates the IP Address of the CPU node that transmits the
pathtrace string.
• The Path Flag is a one-character string, “M”, "P" or "D" that indicates the path on
which the path trace was transmitted (“M”=Main Forward, “P”=Primary Reverse,
“D”=Diversity Reverse). The delimiter used to separate the primary sub-strings of the
pathtrace string is a single character, currently a comma (",").
An example of a complete pathtrace string is as follows:
wspname:bts4:alpha:us1900A,172.20.1.1,P
6.3.1 Pathtrace Creation
Pathtrace is automatically created using information contained in the BTS Connection MIB..
6.3.2 Pathtrace Forward Transmission
Though the BIM, FBHDC, and FSC all create the pathtrace string and report it in their MIB’s,
the FSC is the originator of the pathtrace string in the forward path of the system. The
pathtrace string will be routed to all RAN’s belonging to this tenant.
6.3.3 Pathtrace Forward Reception
In the forward path, the SIF modules in the Hub that are connected to the FSC outputs, as well
as the SIF’s in the simulcasted RAN’s, pass-through the pathtrace strings from their inputs to
their outputs. In addition, the SIF Hardware Control Process (HCP) report the passed-through
pathtrace strings in the SIF MIB for use by tenant processing and other higher-level processes.
In each of the simulcasted RAN’s, the RUC module receives the pathtrace string into its FPGA
from one of its two DIF input connections. The RUC HCP then reports the received pathtrace
strings in its MIB for use by tenant processing and other higher-level processes.
