Teradata Database Ports Usage (1025 ? & more) & Services

I see the following entries in services file: (C:\WINDOWS\system32\drivers\etc)

dbw 3015/tcp # PDE Console Subsystem
sysdbg 6481/tcp # PDE System Debugger
pdepcl 56148/tcp # PDE pcl
pderecond1 701/udp # recond start-up port
pderecond2 702/udp # recond send/receive port
tdmst 1025/tcp # TGTW

When I start Database(V2R6.1) using "Teradata Service Control", I see the following ports in "netstat -a" console
TCP MY_MACHINE_NAME:tdmst MY_MACHINE_NAME:0 LISTENING
TCP MY_MACHINE_NAME:5298 MY_MACHINE_NAME:0 LISTENING

assuming Teradara Database runs on port 1025 (tdmst) , why port 5298 is also listening?

what are the other ports mentioned in services file? PDE* & recond seem to be related with Teradata tools and utilities.

When these ports are getting used ? By Which Apps/Tools/Utility/Services?

Thanks in Advance for Help.
