System functions and features as of R4.1
syd-0570/1.2 – R4.1 – 08.2016
The system supports exchange-to-exchange connections on both digital and analogue
network interfaces. The following settings are possible:
• Not allowed: Exchange-to-exchange connections not allowed
• Digital-digital only: Both network interfaces must be digital
• Digital-analogue also: At least one network interface must be digital
• Analogue-analogue also: Both network interfaces can be analogue
If sections of exchange-to-exchange connections are analogue, the transmission qual-
ity will decrease.
If a user tries to set up an inadmissible exchange-to-exchange connection (e.g. by initi-
ating an exchange enquiry call and then hanging up), the second connection is discon-
nected and user B obtains long ringing after hanging up, to be able to answer the first
connection on hold. This is the case for example if one or both network interfaces are
analogue and the parameter is Exchange-to-exchange connection = Digital-digital
only.
Tip:
In some countries private operators of communication systems are not authorized to transfer an
outside call back to the public network. Explain the situation regarding operating rights to opera-
tors of communication servers already at the negotiation stage.
User-specific configuration
The settings described in the last section can also be configured individually for each
user. The user-specific configuration takes priority over the setting for the system as a
whole. If a user’s settings are not to deviate from the settings made for the system as a
whole, Exchange-to-exchange connection must be set with the assigned permission
set ( =cb) to According to exchange settings (initialization value).
Specially configured abbreviated dialling numbers
Exchange-to-exchange connection can be enabled in general for specially configured
direct dialling numbers ( =vk) ( Exchange--to-exchange connection = Yes). This
allows all types of exchange-to-exchange connections, and is also valid in cases
where exchange-to-exchange connection is barred in the system configuration and the
user-specific configuration. The abbreviated dialling number stored does not have to
be complete, which means digits can be suffix-dialled manually. This allows for exam-
ple exchange-to-exchange connections to be enabled for an entire office branch using
a single abbreviated dialling number.
