Wild guessing.... resistornetwork? capacitornetwork (was something like
that around?)?
That logo belongs to Data Delay Devices, who are still in business:
<http://www.datadelay.com/>
Their part number index lists the DDU4:
<http://www.datadelay.com/asp/alphanum.asp>
With a datasheet here:
<http://www.datadelay.com/datasheets/ddu4.pdf>
But there's nothing about a DDU-4-7992 in there at all. Based on the naming
convention, I'd be inclined to think it was a 7-output delay line, with a
total delay of 992 nanoseconds. 992ns seems a bit dubious though.
It might be worth emailing their tech support department (email address is at
the top of the part number index) and asking them about the meaning of the
'7992' part number suffix.
