Bionic Buffalo Tech Note #103: Introduction to Pegasus Client Support
In systems without U-N signalling, the 
DSM::Session
 object connects with a local
DSM::SessionSI
 object. The local 
DSM::SessionSI
 sets up a session between the
local 
DSM::ServiceGateway
 object and a remote 
DSM::ServiceGatewaySI
object on the server. The server's 
DSM::ServiceGatewaySI
 object performs some of
the same functions as the SRM would in the U-N case.
