2.6.3 Analog Conference
The "Analog Conference" option is supported by XMP1 version 3.8 and
higher. It is implemented by a software package. This software runs on the
processor of the KZU FEK (8) module (62.7040.250.00-A001,
AN00113903).
In the XMP1 node, this KZU FEK (8) module is mounted in any card slot of
the XMP1 subrack. In the Operator Terminal, not the KZU FEK (8) module,
but the "CNF Analog Conference" module is entered in the Node
Equipment. This module represents the Analog Conference functionality.
The "CNF Analog Conference" module provides up to four analog
conference channels for configuring an "analog conference". The
subscribers of a conference are connected to these conference channels
via subscriber interfaces (KZU SUB and KZU FEK).
Note: If the KZU FEK (8) module is used for the "Analog
conference", an application as a pure KZU FEK (8) module is no
longer possible irrespective of the number of conference
channels used.
Note: The following settings has to be done for the E1 interfaces
which are involved in an „analogue conference“:
Info no. 3: „Disconnect also at Ext.-D & Ext.-Dk“ must be
activated.
Otherwise on the E1 interface the signal (user data) in forward
direction would be involved in the signal of the backward direction
if an on-sided error appears.
Thereby no usable transmission of the conference would be
possible.
Info no. 2: „Disconnect immediately when fault“ should be
activated. Otherwise the rebuild of the conference starts after 4 to
5 seconds.
In case of an analog conference, a distinction is made between the following
options:
• Analog conference with signalling (a-bit)
• Analog conference without signalling (modem mode)
