"Trellis graph" is it standard term in graph theory ? What are its properties ? In coding theory (convolutional codes) the graph called "trellis diagramm" is used
to visualize something. 
I wonder is it a standard term in graph theory? Corresponding Wikipedia article is not 
convincing.
If it is well-known graph - what are its properties (chromatic polynom, spectrum, etc...) ?
What is known about it ? What are the references ?
PS
Let me remind definition of trellis graph - it depends on alphabet say {0,1} and 
on two integers "k" (state number = (alphabet size)^p for some "p") and "n".
The graph have k*n vertexes.
Each of vertexes corresponds to words in the alphabet of lenth "p".
Say p=2, we have 4 words 
00   00   ........ 00 
01   01   ........ 01
10   10   ........ 10
11   11   ........ 11
This words are copied "n" times.
Now we have (alphabet size)  size of edges going from each vertex.
They connect the words X  and Y if X stands in l-th column and  Y in (l+1) copy and
Y can be obtained by adding 1 symbol to word  "X" from the left,
and deleting the rightest symbol in X.
E.g. X = 00  will be connected with Y=00 and Y=10
 A: Graph theory and trellis graphs are related, for example, in Chapter 2 of this MSc. Thesis, M. Stylianou, Evaluating the Network Survivability issue of K-best Paths through Graph Theoretic Techniques, Univ. Cyprus, June, 2005.
Another interesting work is S.D. Nikolopoulos, Addressing network survivability issues by finding the K-best paths through a trellis graph, Proc. Sixteenth Annual Joint Conference of the IEEE Computer and Communications Societies - INFOCOM '97, IEEE, Vol.1, pp. 370-377, 1997. 
From the abstract,
*In this paper we aim to offer a solution in the selection of the K-best disjoint paths through a network by using graph theoretic techniques. The basic approach is to map an arbitrary network graph into a trellis graph which allows the application of computationally efficient methods to find disjoint paths. *
In the Appendix, the author presents an algorithm named Net-to-Trellis ...with a help of an example the processes of transforming a network G(V,E, c) into a A trellis graph. ...
