c&p from another site,thanks goes to those responsible
(
This post is comprised of explination given by three persons, it is the closest that I have come to an explaination on TIDS & NIDS.-Grynner)
TID and NID explanation Thanks goes to nania
I was recently asked about this by an associate and I thought it was a good question that required a good explanation and since good questions are probably questions that other people have too, I decided to make it a public discussion. Here is how I understand NID and TIDs:
NIDs are the code references used to identify the satellite and they do not change for a given satellite. Note the table below:
148W (4101)
119W (4100)
110W (4102)
61W (4098?)
If anyone has the NID codes for all the Beverly and Charlie sats then feel free to append or correct the ones above. The TIDs are the code references used to identify the transponder and these will change depending on the nature of the switch/lnbf being used and the number of transponders on the satellite. For example:
TP 12239 on 119W will have a TID of 2 if you are using a legacy setup but
TP 12239 on 119W will have a TID of 20 if you are using DishPro and
TP 12239 on 110W will have a TID of 32 if you are using DishPro
Given the information above, it's a small wonder that the guides are flaky on FTA.
Thanks goes to Conductor
The TID is used for the program guide... If you remove it you won't get the program guide information for that channel. (It has nothing to do with the LNB type) In simple terms it's a pointer into the program guide data stream... what data to assigned to what channel.

That is not completely correct. A DP LNB requires you to use a DP channel list and I believe that channel list will have a different TID than a legacy one. Are you saying that the TID should be identical for both types of lists?
Thanks goes to Conductor Yes, the only thing that changes is the frequency the horizontal transponders reside on. A DP LNB converts the horizontal polarity transponders to a different blockdown frequency. Its new frequency is (25600-orginal frequency). This allows both the horizontal and vertical polarities to be received by the receiver at the same time. A normal legacy LNB will send only the horizontal transponders or when switched the vertical transponders to the receiver. If we check out LyngSat and look at satellite 119, transponder (tp) 1 is at frequency 12224 and tp 2 is at 12239, difference of 15. They’re so close in frequency that they would collide if it wasn’t for the polarity. But the only way for the receiver to receive them is to either only send one (legacy) or move one away from the other in frequency (DP). So with a DP LNB transponder 2 which was at 12239 now sets at 13361 with the same NID and TID information. Check out LyngSat it also tells the NID and TID information for the transponders... note the TIDs for spotbeams also. Thanks goes to Dr Spark TID- Transponder ID -> each transponder in the sat has a diferent ID.
NID -Network ID-> each network has a diferent ID.
for instance all the transponders owned by the same provider has the same NID, but since their are diferent transponders they have diferent TID.
