Communication delay & jitter delay modelling

How to consider a communication & jitter delay for a signal in matlab.
eg: If there are two system say A & B. System A & B both read sinusoidal signals. Now i need to communicate the system B signal through system A.
But system B data is linked through CLAN (optical communication) in system A so there will be some delay.
So my query is, how to model that communication & jitter delays present in the CLAN port.
Need your best support for the same.

This is confusing to me, because "signal" is the term for connections between blocks in Simulink. So, are you wanting an answer for a Simulink implementation or a Matlab code implementation?
Also, if you can show a block diagram of the problem perhaps it would be more clear what you are asking for.

Here is my interpretation of what you are asking. It seems that this woud be very easy in Simulink.
You have signal PT which is available in System A and System B. System B performs some process and provides another signal to System A which is delayed from signal PT.
In Simulink, you would simply add a "transport Delay" block on the Signal going from B to A, assuming that your model is structured as a "continuous time" model. Inside the transport delay block, you simply specify the duration of the delay time.
If the model is a discrete time model, then the "Memory" block can be used to implement a delay. The memory block specifies the number of discrete time samples to delay, so in this case, the magnitude of the delay is limited to an integer multiple of the discrete sample time (i.e. the memory block specifies a delay of 1 sample or 2 samples, etc.)
