* This is basically a glue dissector for the Cisco SM protocol. It sits
|
|
|
|
* between the RUDP and MTP3 layers in conversations on port 7000 between
|
|
|
|
* SLTs and MGCs. A link to an overview of the technology :

|
|
|
|
*
|
|
|
|
* I'm unable to get local debugs of this protocol, as the SLT's are
|
|
|
|
* slow cpu cisco 2600's, and they tend to drop the signalling links
|
|
|
|
* if you turn any debugging on! But there's not much interesting
|
|
|
|
* here, its just glue to get the ISUP/MTP3 data nicely.
