I have a small Nitsuko Vs system installed at my SOHO. I have just purchased a Nitsuko OPX for this system and got it installed. I can use any digital set on this extension with no problems. After removing the digital set and replacing it with the OPX, I get nothing. A toner verifies that there is System battery there, however, I cannot pull dialtone from the system with my butt-set. If I call the station, I get RNA at calling parties side, and nothing at all on the called party side. I don't even see ring current with my toner. I have checked the system programming for that extension, as well as the COS and am not sure what the heck I am missing.

opx needs to be set as type 51

if it doesn't take that try 52 , its been awhile and its one or the other

51 popped into my head right off now I'm thinking 52

And needs to be connected to 2 digital ports.

that depends whether it is one or two port , the single port uses a single digital port

the two port require two digital ports

also want to add these weren't terribly robust so a used unit may be DOA

I set the OPX to Circuit type 51, however, this does not fix the problem. Also, this is a two port OPX, but there are only 4 conductor line cords for this unit. How does it use two ports? The station side of the OPX is only able to accept one line cord, which is 4 conductors, Since this is a two pair switch, how would I connect this to two ports?

PM sent

You just jumper 2 digital ports together and then to a 4 cond jack. Both digital ports have to be programmed 51. You will need to reset after programming. I think I remember you have to use a odd numbered port for the fisrt connection.

Sorry Skip if thats what you sent him by PM. If he get to much deeper he is going to need to call for Tech support.

I have a NVM 202EX. What is the easiest way to change a name in the directory from an old employee to a new employee. Can I do this from a telephone?

sorry, I guess I should have stated that this issue is fixed. Thanks to you Skip, much obliged......much easier on Norstar and Nortel.
