AlphaCom XE - Installation, Configuration & Operation
This board is likely to be installed in XE servers with DTMF telephones
due to the expanded capacity.
The default DIP switch settings should normally not be changed.
See separate LCM documentation for more information.
AlphaCom XE20/XE26
The ATLB-12 boards are connected to the LCM via 1.5 m (100 9501
011) or 3.0 m (100 9501 014) connection cables, one for each board.
Stations are connected to the terminal strip, the first telephone on Line
Board 1 to the terminals marked 1A, B, the next to 1C, D and so on.
Telephones on Line Board 2 starts at terminal 7.
RCOs are taken from Line Board 1 and are available on terminals
marked 1K+/- to 6K+/-.
RCO function is set by the switches S1 to S6.
Poten Free
-
Potential-free closing contacts, max. 250 VAC, 5 A
24V
-
Fused internal 24VDC, max. 1 A
Telephones may also be connected to connection boards 100 9930 202
- two connection boards are needed per ATLB-12 board.
AlphaCom XE7
All telephones are connected by means of pluggable screw terminals on
the server backplane.
The ALTB-12 board can be placed in any board positions 1-6. The
example drawing shows an ATLB-12 board in position 2. Avoid using
boards in position 1 if possible as connection points 5 and 6 are
reserved for program input by default.
2.2.12 AGA - General Purpose Audio Interface
The AGA board is a multi-purpose audio interface board used for
program feeding or speech communication between modules. There are
easily accessible potentiometers at the front for input sensitivity control
of the audio channels.
The impedance can be set to 600 ohm or ‘high’ for each input by strap
switches on the board.
Further information on the AGA board is found in datasheet
A100K10182.
Multi program distribution
Each board provides 16 audio inputs for program distribution when used
in AlphaCom XE20 or XE26. There can be 1 to 4 boards in a module
placed in positions 18 to 21.
An AGA connection kit, 100 9930 300, has to be purchased to connect
the audio sources. The kit contains a filter board, a connection board,
and an interface cable.
AGA boards can be placed in board positions 1-6 in an XE7 server but
the number of inputs are reduced to 6 per board. Input adjustments
are performed by potentiometers 4, 6, 8, 10, 12 and 14. The program
sources are connected to the
c
and
d
terminals on backplane
connectors.
Audio distribution in AlphaNet
Each board provides 6 audio channels between the servers.
There can be any number of AGA boards in each server placed in
any position. Positions 20-23 are recommended in XE26 to avoid
modifications of the backplane.
Use the same filter board with cable and connection board as ASLT.
