WIN500 Log question

[W2ER]

Below is the log from a local Motorola Type II SmartZone system.

My questions are, what does the TGL/O mean? Also why do some the entries have radio ID's and others have a 5 digit number such as 00530? I thought it my be an object number but I looked and 00526, 00530 etc are not valid object ID's.

Thanks for the help.
