18.8. DSDL - Don't send diversion LEG information 
Feature:
Network-wide call forwarding and call forwarding no answer
Function:
Parameter DSDL can be used in the COT of a trunk to suppress the sending of protocol
elements "Diversion Leg Information 1 to 3" to the partner system.
Information about the origin and destination of call forwarding is transferred in
these
protocol elements.
If a provider analyzes these elements and if it only permits call diversion, then
call
forwarding is not executed when encountered.
Without diversion LEG information, the remote side cannot recognize whether the call
is one
that has already been diverted. It can therefore perform another call forwarding operation
for DSS1 (Digital Subscriber Signaling System No. 1) and Q-Sig -based protocols.
