Nortel VMI (NT8B89DA-93) analog FXS ports not functioning

Hello all,

Long-time listener, first-time caller (hah, no pun intended...really).

Got an MICS 4.1 system we need to hook a VMI up to, which we will be using as a 2-port ATA. I bought one off of eBay that was supposedly pulled from a working phone system last year and then sat on a shelf for several months before I bought it.

I can hook it up to a KSU port and see the new feature code to program it come on-line. I can talk to it at F9*3 and on the F9XX feature code it allocates for itself. I can dial its extension # and hear the ringtone in the phone handset I'm dialing from. So the MICS is aware of its presence, and it is responding properly.

But I cannot, for the life of me, get an analog handset/FXO device to "work" on the VMI. When I ring the VMI's extension, the phone attached to the matching analog port does not ring. If the phone connected to the VMI goes off-hook, I hear no dialtone (which I should, according to page 4-4 in the manual).

I'm worried that, in a past life, some doofus plugged the KSU line into one of the FXS ports and fried something.

Does its behavior indicate to you all that this VMI unit is most likely physically defective, or am I missing something really simple here?

Thanks, everybody!

VMI programming: I reset both digital ports on the VMI to default values (F9XX -> VMI Admin -> Next -> DN # -> Next -> Feature Table -> Clear -> Default Data? -> Yes).

DN programming in the KSU: as directed by the VMI manual on page 3-3.

Less confusing if you could post in one forum only.

If programmed correctly and wired correctly then usualy its the device at fault.
Try another VMI.

What device are you installing? sure you need VMI?

I need an ATA with disconnect supervision and DTMF passthrough which will be connecting to an analog FXO port on an Asterisk box which will in turn be terminating a remote VoIP handset. The idea is to have a remote phone that has an internal office extension/DN and to use IP as the transport/trunking mechanism.

I still have my fingers crossed that Nortel will come out with an "ata3" that will pass dtmf before their sell out is complete.
 
Hah, I wouldn't bother holding your breath.
