OK.  Good.

Yes, it's a layer 8 problem.  I actually have 2 different situations:

Situation 1:

We have two locations, one in SBC territory, one Valor Telecom territory.
We want fiber between the locations, but this is not possible at the moment.
SBC has their GigaMan service, but, we can't run GigaMan betweeen the two
locations because it is in two different territories.

We have a colocation facility in SBC territory which has fiber in it to
location 2.  So, we ran a GigaMan circuit from our location in SBC territory
to the colo facility.  The handoff from SBC is SX.  We had an old 3508G
switch, so we put that switch in the colo facility and ran ZX from the 3508G
to the 2nd location.  So, we now have ZX-ZX from one 6509/Sup720 to the
3508G, then we have SX to the SBC GigaMan to the other 6509/Sup720 handed
off to another SX connection.

So, this is a technical problem.

The other is a Layer 8 problem involving Valor Telecom.  I'd rather not go
into those details on list.  :-)
