10GE-WAN-PHY to STM-64

Question

Hello,
I would be grateful if anyone can help me with this problem.
Is it possible to interconnect 10GE WAN-PHY port on router to STM-64 port on multiplexer?
Is it generaly allowed to inerconnect SDH and SONET (or their frames and signals are not compatibile) i.e oc-192 and STM-64?
I have DWDM with four STM-16/OTU-1 ports. I've planned to multiplex those 4 ports to one STM-64 and connect it to 10GE WAN-PHY router port.
(router)10GE-WAN-PHY-----STM-64/OTU-2 (multiplexer) 4xSTM-16/OTU-1-----4xSTM16/OTU-1(dwdm).
Is it feasible or I need some additional equipment?
thanks in advance,
A.

1) When I connect 10GE WAN-PHY router port to STM-64 box, will router send STM-64 frames, or it has different frames then SDH?
Is the 10GE WAN-PHY also compatibile with OC-192?
Yes it sends STM-64 frames (but it doesnot have network management features which SONET/SDH STM64 interface have) See this link
http://www.cisco.com/en/US/prod/collateral/modules/ps6267/product_data_sheet0900aecd80715dc5.html
So  one to connect to a DWDM STM 64 /SONET- 192 trasponder which then makes  a proper SDH/SONET frame with all those management bytes.
Same port can be either used for STM 64 or SONET 192. This STM64/SONET192 are still made from smaller SDH/SONET frames
2) Do you know if Cisco has a box that can  interface two boxes  STM64----OC192 (or OC-3 --- STM-1)? Which type of  box is that generaly?
Are you crossing  continent with your own infrastruture , service provider have  crossconnect that do that for them this conversionTellabs,Fujitsu etc  RAD for smaller line rates ? Cisco have boxes which either can be SDH or  SONET but see this link. Might be helpful.

3) (router)10GE-WAN-PHY-----STM-64/OTU-2 (SDH/SONET box) 4xSTM-16/OTU-1-----4xSTM16/OTU-1(dwdm).
I   wasn't clear enough in my previous post. I was thinking to put box   (multiplexer) between router and DWDM, which on one side toward router   will have STM-64 and toward DWDM will have four STM-16 ports.
Is the scheme that I corrected now above in point 3) allowed?
You  can have point to point link where STM 64 are demultiplexed to STM 16.  This is the way how 100G are trasnported over 10 x 10G. I dont see any  benefit on a extra box with point to point link.
But If this 10GEWAN is your hub and have spokes which have router with STM 16 interface, then you can make 4 STM 16 pipes. All these you are trying to achieve are possible but you may need extra equipments to get the result.
For one more opinion you can consult with Solution specialist from Cisco. Generally all marketing guys try to sell more than what you need.
