Replacement for NTDU27AB Signaling Server

[AJ9U]

All of our systems are CS1000M or CS1000S, running on release 4.0 or 4.5 software. We have a stash of NTDU27AB signaling servers for spares, but that stash has dwindled due to failures. Is there a replacement/newer model available that does not require a system upgrade?

You could probably find a place to repair or refurbish the ones you have as they fail, then return to spare inventory.

There are 7 of them on Ebay right now, and really you could probably find more if you wanted. I would say it would be cheaper to upgrade to latest hardware but you could just repair/replace those as the break with used ones.
