It's a mix of Nera and Ceragon equipment.  Ceragon bought Nera in
2011.  Looks like the same stuff except for the badging.

This equipment is split - indoor and outdoor units (IDU, ODU), with up
to 300m of coax between them.  These IDUs appear to have management
ethernets and 4 x T1 interfaces on a 50-pin interface connector that
you may recognize from applications in SCSI-2 and HSSI land.

This auction is for just the IDUs.  Presumably the ODUs are still
bolted to towers somewhere or got sold for scrap.  Or maybe listed
elsewhere on that same auction site.

But IDUs are not especially useful by themselves.  It's like buying a
transceiver with no output stage beyond the modulator and no receiver
front end ahead of the IF.
