I think the term 'unchannelized structured service' just refers to a service with one channel that uses up all the timeslots. In fact, if you look at the CES specification from the ATM Forum ('Circuit Emulation Service Interoperability Specification -
AF-SAA-0032.000') you will see that the very definition of a strucutred service is that it is as 'Structured DS1/E1 Nx64 Kbit/s Service' - there is no provision within that for unchannelized operation. However, it does allow for all 24 timeslots to be used to form a channel.
I don't think the issue is your understanding... the issue seems to be the meaning intended by the CLI of whatever system you are configuring.
looking at an E1 the terms are more understandable (at least for me ;-).
Unchannelized E1 -> 2048 kbps bitstream - no DS0s
Channelized E1 -> 1984 kbps data rate, TS0 used for framing.
Both can be used to transport frame-relay or ATM cells in OSI layer2 as an example.
The terms in your last post probably refer to something different. I assume UNSTRUCTURED will just transport the bitstream of the interface - maybe not even looking for Byte boundaries and especially independant of Layer2.
STRUCTURE will look for structures in Layer2 like Frame-relay, ATM, etc. This is possible for an channelized or unchannelized E1 (see above). The confusion arises probably from the fact, that there are different structures in different OSI layers. In this sense STRUCTURE or UNSTRUCTURE are relating to Layer2 and not to the terms in Layer1 used for an E1 or T1. This view is also supported through the terms "channelized" and "unchannelized", which refer to Layer1 settings.
