ds0s are not part of sdh tho, the docs say it can go down to E1s and do 
channelized E1s, this implies to me a kind of 2 stage muxing is occuring, the 
first bit being SDH, the second being G704 

the muxing of E1s into STM1 and T1s into OC3 isnt the same tho .. so I can see
why the hardware only does one variety, probably to save costs but its odd there
isnt a T1/SONET version..
