TN corruption is caused when the protected & unprotected unit pointers are invalid, or have become missing from the card pointers.
The corrupted TN can be printed as normal in LD 20, but you will not be able to make any changes to it. It can’t be removed in LD 11. You will also get the error “SCH0128” message.
e.g
REQ: “CHG” or “OUT”
TYPE: 2616
TN 4 0 0 6
SCH0128 = Terminal does not exist.
TN ****
Another way to find out if a TN port is stuck in set relocation, Is to do a “STAT” first in LD 32. Use e.g. “STAT 4” etc to list out all the TN’s on the card that port is on.
REQ: STAT 4

01 = UNIT 01 = IDLE (2616)
02 = UNIT 02 = IDLE (2616)

04 = UNIT 04 = IDLE (2616)
05 = UNIT 05 = UNEQ
06 = UNIT 06 = MSBY (2317)
07 = UNIT 07 = IDLE (2616)

REQ:
This situation tends to happen only on older Option 11 software versions. The cause of this is when a customer picks up the handset on a TN port that has just become spare. The old DN on that TN port was in the process of being moved via TTY programming to a new TN position.
There is a Model set template that exists for the Option 11 software. This will have now become corrupted.
There are a number of ways to resolve this problem, & I’ll start off with the easy & safe method. You will need to be in contact with an Engineer / Customer on site. If they are providing a new extension, It may be possible for them to unlock the TN port.
This is done my using a revised Opt11 “Model” set (Usually 20) for either the M2006, 2008, 2216, 2616 & Orion type phone versions. First of all, I would print out the phones type model set to check if it exists in software.
e.g.
>LD 20
REQ: PRT
TYPE: 2616 M
MODL 20 (You can just key in “Enter” to list out all the model sets for the set type!)

Some of the later Meridian Option 11c databases will not have any model sets programmed on the system. In that case it’s best to create a new model set 20.
Don’t programme in two SCR / MCR keys etc. Just provide a basic phone with key 0 as SCR. If you find that the model set 20 exists, then check or make key 1 “Null”.
The next thing to do, Is to plug the phone in onto the faulty TN port. If the phone has a display fitted then you may see “20” appear on the right hand side of the terminal screen, when the handset is picked up.
All that needs to be done on site, Is to get the Engineer or Customer to key in ## on the phone & replace the handset. One of two things should then happen.
1) The TN port will become spare & unequipped. (The port can now be used)
2) Or a new digital phone will be shown on the TN. (TN can now be deleted)
Whatever the result is, The TN can be used for programming again.
