System functions and features as of R3.0
syd-0367/1.3 – R3.0 – 03.2013
5. 1 Overview
From the system’s viewpoint a destination is an interface (e.g. network interface or
terminal interface). In this context user groups or user configurations are also rout-
ing elements, not destinations. Fig. 44 shows how all the routing elements relate to
one another:
[1] Routing via the numbering plan to one of the elements. Applies only to calls from the permanent net-
work PISN (page 189)
[2] Routing via a transit route (page 261) or as [1]. Applies only to calls from the permanent network PISN
[3] Does not apply to calls from the analogue network
[4] Outgoing KT calls
