signaling (LEI mode) include:
1. Calling Line ID Presentation (CLIP)
2. Redirecting Line ID Presentation (RLIP)
3. Message waiting indication (MWI)

When an incoming call over the TDM/IP network or a CS 1000 originated
call is directed towards the CAS+ compliant system, Calling Line ID can
be provided over the CAS+ interface. This is assuming that the incoming
call has the CLID without any presentation restrictions.
When an incoming call over the TDM/IP network or a CS 1000 originated
call which has undergone redirections is directed towards the CAS+
compliant system, Redirecting Line ID can be provided over the CAS+
interface. This is assuming that the incoming call has the Redirecting
Line ID without any presentation restrictions.
Message waiting indication can be provided over the CAS+ interface.
