atcomsystems.ca/forum Forums TDM Business Telephone Systems NEC Telephones & Systems EE 48/192 Station Expansion Problem

A base system 192 is 48 ports total.

16x32 maximum, so it must have a PKU chip since the system had more than 32 stations assigned before he added the new ESi card (32 digital phone ports plus his vm ports).

If the ports are green in 1-2-04 it means they are assigned as CAR (virtual) and not available for use with real desktop ext's.

Go back and look at 7-1 for the card you just assigned, (cabinet 1 slot 3) it will tell you the first port assigned to that card.

Program your ext #'s to those ports in 4-10 then try cross connecting an ext to the yellow/orange pair on the first amp tail ( the one with your CO lines ).

I have a feeling you do not have any stn #'s assigned to the ports on the card in slot 3 and therefore the ext's will not come up.

Scott and Dog....first off, thanks for taking the time to respond.

Checked 1-2-04:

04:CAR ASSIGN:01
LK1 to LK11 - Red
LK12 to LK16 - Off

04:CAR ASSIGN:33
LK1 to LK3 - Red
LK4 to LK16 - Off

04:CAR ASSIGN:65
All LK lines - Off

04:CAR ASSIGN:97
LK1 to LK8 - Off
LK9 to LK16 - Red

Also on S3 - first port is 37 (so 37-44)
S4 - first port is 01 (01-08)
S5 - first port is 09 (09-16)
S6 - first port is 17 (17-23) vm 25-28
S7 - first port is 29 (29-36)

Ran 4-10 Ports 37-44 are assigned stations 131-137.

Haven't installed the cross connection yet, my wiring guy is coming in today or tomorrow. Will let you know of the results.

Thanks again for your help.

Yeeeeefreakin'hawwww.....

FINALLY.

Doghart....you are da' man!!!!

As per your instructions, went to the wiring block.

"Program your ext #'s to those ports in 4-10 then try cross connecting an ext to the yellow/orange pair on the first amp tail ( the one with your CO lines )."

The yellow/orange pair was the first station added (37). This was the last row of blocks on my wiring block.....(duh, check em' all next time).

All is well with the world, although I do have a quick question.

I am using DTU-16D-2 and DTU-8-1 phones, I was given 8 used ETW-8-1's. Needless to say they do not work on the system. Can the 48/192 handle the two different types (DTU & ETU) phones and if so, what is the program block?

I have looked and did not see anything in the manual.

Again, getting the stations hot and properly assigned makes taking off tomorrow for my birthday a huge relief. Thanks again...


FORE!!!!!!!!!!

The ETW series phones use the Blk/yellow wires at the jack!

T & R is correct.

The older ETW phones will work, you just have to cross connect them to the second pair on the station cable (usually the white/orange) which connects to the yellow/black leads inside each jack.

Kind of a P.I.T.A to keep track of, especially if all your jacks don't have both pairs terminated.

If you don't need to use the ETW's then avoid it.

After reading this post I a PKU expansion is this on the cpu board?

The reason I ask is because in 1-2-04 my first 4 line button come up red.

Yes, it is on the CPU.

Scott.

Thanks have founded my problem for some reason I was only seeing 4 channels,pulled the cpu dumped tne memeory had to do it about 3 times finally came up with all 20 channels.A big thanks to all you guys for your help the last few nights.

Took your advice Dog, ordered new DTU's. Now I have 8 ETW's for sale......anyone interested?
