Description
ALFRED is a digital announcement device with the following features:
-Courtesy announcement
The device must be connected to a analouge PABX extension line.
This port has to be programmed on the PABX to receive, using features
like call diversion or call rerouting, all calls which can not be answered
by the attendant or other extensions. Depending on the required
function the calls can be diverted to ALFRED only if the attendant or
the extension is busy, doesn't answer within a specific time or in any
case. With small PABX were call diversion or call rerouting features
are not available the device should be programmed to receive incoming
calls at the same time as the attendant. You can program then a call
answer delay on ALFRED giving enough time to the attendant to
aswer the call if he/she is free. After answering the call the device can
send an up to 60" long message. The message can be recorded by the
user itself using the build in microphone or an external source like a
CD or MC player. At the end of the message the device will send a
flash signal, followed by an up to 16 digit long telephone number.
This will connect the answered call back to the attendant, or other
extension. Now the external call will be placed in the waiting queue
of the PABX. Using an optional MOH device like the Phonphon, the
waiting caller can now receive waiting messages with a background
music. The external music on hold source can be also connected to
ALFRED and then forwarded to the PABX MOH input as well. In this
case you will have a courtesy announcement system with the same
background music for all the duration of the process.
- Automated attendant
This feature can be activated by programmation. With this feature
activated the caller party can be invited, during the greeting message,
to dial a specific internal number using his DTMF dial pad. If the caller
will follow the instruction, the device wil stop the outgoing message
as soon as a valid DTMF digit is detected. At the end of the dial
ALFRED will transfer the call to the dialed number and not to the
stored one. The device will not survey the dialed number. Only the
number lenght is programmed in the device. This gives a high grade
User guide ALFRED Issue 1.01

of flexibility in the possible applications of this feature. To ensure that
the external caller may not activate PABX features or external calls,
the extension line with the connected ALFRED should be restricted
using the class of service programmation of the PABX.
If the caller doesn't dial a number, or if the dialed number is shorter
then the programmed lenght, the device will forward the call the the
programmed extension at the end of the message or after a time out.
- Digital announcement device
If no telephone number is programmed, the device will work as a
digital annoucement device. After the message the connection will
be released.
- Digital announcement device with start/stop interface
Thedevicehasabuildin start/stopinterface.This interface can be used
to connectALFREDto larger PABX withthisspecificinterface(likeSie-
mens Hicom 300 or Nortel) or ACD systems.With this interface the unit
can be used also as digital announcement device for other kind of
installations (i.e.PA systems).The start/stop interface has a start input
(5 to 48Vdc), a busy signaloutputand aisolated LF signal output.Both
start/stop and t/r interface can be used at the same time, as far as for
both of it the same message is used.
- Modular expandable
Up to four units can be configurated together as one device.One of the
units is automatically indentified as master unit.All the programmation
and the recording of the message is done on the master unit.This unit
will then forward automatically the information and messages to the
connecteddevices.Inthiswayyoucan configure a multilinedevice with
the same message for all channels. After the recording and
programmation all units will work stand alone for the normal business.
The following programmations can be done on the ALFRED:
- 1 to 16 digits long telephone number (0 bis 9, *,#)
User guide ALFRED Issue 1.01
Page 5
- Delay on answer (0 to 99 calls)
- Flash signal duration (0 to 999 ms)
- Internal numbering plan lenght (1 to 16 digits)
The programmation is done using DTMF dial signals. For this procedure
ALFRED has do be called, after the programming mode has been
activated. After the answer you will receive a acknowledge tone and
the programmation can be done using a DTMF dial pad. Follow the
instructions on the following pages.
The message is stored on a EEPROM memory using the DAST
procedure. This memory is protected against loss of data due to power
failure for a period of ten years. The message can be recorded using
the build-in microphone or an external source.
The message volume can be regulated. The output inpedance is about
600 Ohm. The power supply is provided by the attached plug PSU.

Start/Stop interface
The start/stop interface is used to connect ALFRED to larger PABX
(like Siemens, Nortel or Alcatel). Over this interface the PABX can
control the the stored message and synchronise itself with the lenght
of it. Applying a DC voltage between 5 and 48 V on the pins 12 and
13 of the DB 25 connector the message will be started. At the same
time the busy relais contact on the pins 11 and 9 will be closed (opened
on the pins 11 and 10). At the end of the stored message the busy
contact will be opened (closed) again. With the busy contact the PABX
can determine the aviability of the device for a new call. The message
is send on a 600 ohm galvanic isolated output (LF signal output on
pins 4 and 4 of the DB 25 connector). The device is delivered with a
DB 25 plug. The connection cable to the PABX has to be prepared on
the installation site.

Configuration examples
Example 2. Courtesy announcement with no answer
- Call diversion after time is programmed for the attendand/extension.
- The call is forwarded to ALFRED only if the attendand/extension
doesn't answer.
Example 1. Courtesy announcement with busy attendant
- Call diversion on busy feature is activated for the attendant.
- If the attendand is busy the call is diverted immediatly to ALFRED.

Example 3. Courtesy announcement with no answer or busy
attendant
- Attendant and ALFRED are called at the same time.
- The call will be answered by ALFRED only after a programmed delay.
Example 4. Courtesy announcement with busy operator and
automated attendant
- Call diversion on busy feature is activated for the attendant.
- If the attendant is busy the call is diverted immediatly to ALFRED.
- The waiting caller can dial during the message an internal number
using the DTMF dialpad.

Night service
Example 6. Night message
- Alfred is programmed as night answer machine.
- The call will be answered immediatly. At the end of the message the
connection will be released.
Example 5. Automated attendant
- Alfred is programmed to receive all incoming calls.
- The caller can dial during the message an internal number using the
DTMF dialpad.
- If no number is dialed the caller will be connected to the attendant.
