[c-nsp] Channelized DS3 over SM fiber handoff

Allstream at 151 front street in Toronto does this.  They run a single
strand SMF and they terminate it into a form of a media converter, which
passes off 2x BNC as expected for a DS3.  They do this for both clear
channel and channelized DS3.

Interestingly enough, our channelized OC12s come in on a pair of SMF
from them.

I would imagine you would need a similar media converter - I'm sorry I
don't have the model number of the equipment Allstream uses.  All I know
it is some sort of WDM equipment (obviously) on the fiber side.

Maybe; odd though if one asked for a DS3. If that's the case you can
just get an OC3 port adapter.
