Part 2 Call Routing 325
Analogue-Analogue (A-A) or Digital-Analogue (D-A)
• Release on the analogue interface cannot be guaranteed with these connec-
tion types. On analogue network interfaces the PBX only recognises loop inter-
ruptions but not polarity reversals, busy tones, etc., as a release criterion.
Detection of the loop interruptions can be activated or deactivated throughout
the system.
• Any exchange-to-exchange connection is disconnected at the latest after 2
hours.
• The maximum duration of an analogue exchange-to-exchange connection can
be further restricted for the A-A connection type (1...120 minutes).
Note:
As release cannot be guaranteed for connection types D-A and A-A,
unintentional high costs can occur. What's more the national guidelines
and regulations should be observed before enabling these connection
types.
