No, for what ever reason, any OTA stopped working on NYC Interoperable Communications Network (NYCICN). It stopped saying alias in the column and it stopped mentioning anything about Dsdplus server.
The pic I posted is from CLMRN and the first time seeing multiple underscores where the alias value should be.
The underscores are simply radio IDs that had OTAaliases which were captured and sent to the server. At some time later on all of those ______ would be replaced with the real cleartext alias value once the batch of aliases (which could include aliases from 50 different systems) was ran. So, as for CLMRN, everything is working as intended.
I probably fed misinformation before. The word "alias" in the common doesn't necessarily mean there is an alias. It means that DSDPlus is checking for an OTAalias. If it doesn't find one, it isn't going to display Alias next to a voice transmission with that RID again until the reacquisition time is met.
So you have have ten separate voice conversations where you see "Alias" next to them. It's checking for the existence of an OTA Alias or for the existence of an updated OTA Alias. Once it checks it, if there was a new / updated alias it sends it to the server. If there is already an OTA alias and it is the same as what is in the .radios file, it doesn't do anything. And there will be no more mentions of "Alias" next to voice comms with that RID until reacquistion time. That's my current understanding.
So in the case of NYCICN, perhaps you and/or somebody else already captured all of the OTA Aliases for the RIDs you typically see on the sites you monitor, and they are up to date, so no further "Alias" activity will happen until reaquisition time.
Also, keep in mind that some systems just don't have OTA Aliases enabled for all radios. And some sites on some systems will send OTA Aliases and others won't. Most of Ohio MARCS sites do not send OTA Aliases. But, get over into Zone 4 (SW Ohio), and there are multiple county simulcasts that are sending OTA aliases. Some systems may just have OTA aliases for a very small subgroup of radios, for instance a specific department, or consoles, etc. Again that's my understanding.
Anything you have described sounds completely normal to me based upon the systems I monitor (WVSIRN and PASTARNET).
