1INTRODUCTION
MAGIC EECallows the conversion from ETI to EDI and EDI to ETI signals.
Typical applications are Ensemble Multiplexers, which cannot generate an ETI signal
anymore (e. g. Fraunhofer ContentServer), but which must be fed to the transmitter
via E1 lines with ETI or Ensemble Multiplexers, which only have ETI inputs/outputs
(e. g. Rohde & Schwarz DM001), but which are to be fed via IP lines with EDI.
The system has two LAN interfaces by default. These are freely programmable in
terms of functions, configuration, monitoring, SNMP and EDI input/output. The ETI
interface has one G. 703/G. 704 input/output each.
The system is configured via the PC software included in the scope of delivery and
displays the status of the ETI or EDI input data streams and all system parameters in
a very clear manner. All events are stored in the device in a log file, which can be
retrieved via the PC software or alternatively stored in a network folder.
MAGIC EEC supports SNMP v1/v2c protocol for connection to up to four independent
network management systems.
In addition, alarm messages can be output via eight potential-free and programmable
contacts. Alternatively, eight programmable TTL GPIO contacts are available.

1.1 Conventions
In this manual the following conventions are used as text markers:
The Tip symbol marks information which facilitates the operation of the system in
its daily use.
The Note symbol marks general notes to observe.
The Attention symbol marks very important advice that is absolutely to observe. In
case of non-observance malfunctions and even system errors are possible.
1.2 Safety
The unit described has been designed to the latest technical parameters and
complies with all current national and international safety requirements. It
operates on a high level of reliability because of long-term experience in de-
velopment and constant and strict quality control in our company.
This manual contains basic safety instructions that must be observed during
configuration and operation. It is essential that the user reads this manual before
the system is used and that a current version of the manual is always kept close to
the equipment.

1.3 General safety requirements
To keep the technically unavoidable residual risk to a minimum, it is absolutely
necessary to observe the following rules:
•Transport, storage and operation of the unit must be under the
permissible conditions only.
•Installation, configuration and disassembly must be carried out only by
trained personal based on the respective manual.
•The unit must be operated by competent and authorised users only.
•The unit must be operated in good working order only.
•The device must be protected from water.
•The device may only be installed in indoor rooms.
•The device may only be cleaned with a dry cloth.
•Any conversions or alterations to the unit or to parts of the unit (including
software) must be carried out by trained personnel authorised by the ma-
nufacturer. Any conversions or alterations carried out by other persons
lead to a complete exemption of liability.
•Only specially qualified personnel are authorised to remove and override
safety measures, and to carry out the maintenance of the system.
•External software is used at one’s own risk. Use of external software can
affect the operation of the system.
•Use only tested and virus-free date carriers.

1.4 Construction
MAGIC EECcontains a mainboard with an additional connector, a display, a keypad
and five LEDs.
The functions of the system are implemented in a 19” x 1U housing, the dimensions
are 434 mm x 44,5 mm x 260 mm. MAGIC EECcan be used as a table-top device or
it can be mounted in 19" racks. The 19” mounting brackets are included in delivery.

1.5 Functionality
MAGIC EEC is equipped with a G.703/G.704 input/output (for ETI signal) and two
LAN interfaces which can be configured freely regarding their functionality
(input/output for EDI signal, control and configuration, SNMP). A second ETI
module can be equipped, whereby an additional and unrestricted ETI output is
available. This may be used as a monitoring output or to supply a redundant
ensemble multiplexer, for example.
Configuration and control are especially comfortable with the MAGIC EEC Windows
PC software which is included in delivery and which communicates with the system
via the LAN interface.
For an external alarm signalling eight TTL contacts and eight relays are provided. All
alarm or status events are also stored in an internal system logfile, which is
readable via the logfile browser of the PC software. Alternatively, an automatic
download in e.g. a network folder is possible.
Via the integrated SNMP agent, which supports the SNMP v1/v2 protocols, control
of the system can be realised for up to four independent network management
systems.
With the optional SDC upgrade a MAGIC EEC system can be upgraded to a full
MAGIC SDC Switch & Converter.
Options
•Monitoring output
A second ETI module can be optionally equipped, which means that an
additional unrestricted ETI output is available. This can be used, for
example, as a monitoring output or to supply a redundant Ensemble
Multiplexer.
•SDC Upgrade
The optional SDC upgrade allows a MAGIC EEC system to be upgraded to a
full-featured MAGIC SDC Switch & Converter.
•Dual converter mode
With this upgrade MAGIC EEC has two independent ETI/EDI converters.
For the Dual Converter mode you need a MAGIC EEC with monitoring
output (second ETI module).
•Dual LAN Upgrade
Optional extension with two additional Ethernet interfaces. The
assignment of functions such as EDI, SNMP etc. is freely configurable.
However, a second EDI module can then no longer be assembled.
Redundant Power Supply
Optionally a redundant power supply can be used, the 5V DC table power
supply is included in this hardware upgrade.
•N+1 Redundancy Upgrade
The N+1 redundancy upgrade adds an additional EDI input to the system
to enable non-seamless redundancy switching in the event of errors in the
EDI input signal of the main path. This option provides a cost-effective N+1
redundancy solution using our MAGIC DABMUX Go or MAGIC DABMUX
plus in an N+1 multiplex setup. This feature is only available in EDI → ETI
conversion mode.

2PUTTING THE SYSTEM INTO OPERATION
2.1 Mounting
With its dimensions of (width x height x depth) 434 mm x 44.5 mm (1U) x 260 mm
the MAGIC EEC system can either be used as desktop device or mounted into a 19-
inch rack. 19“mounting brackets are included in delivery. When mounting the unit
please keep in mind that the bending radius of the connected cables is always
greater than the minimum allowed value.
When the MAGIC EEC is installed, please make sure that there is sufficient cooling:
It is recommended to keep a spacing of ca. 3 cm from the openings. In general, the
ambient temperature of the system should be within the range of +5 °C and +45 °C.
These thresholds are specially to observe if the system is inserted in a rack. The
system works without ventilation.
The system temperature can be indicated on the display under MENU > STATUS
INFORMATION > DEVICE TEMPERATURE or in the software under Extras > System
Monitor > System Temperature.
During operation humidity must range between 30 % and 85 %.
Attention! Incorrect ambient temperature and humidity can cause functional de-
ficiencies.
Improper use of the unit can lead to a loss of warranty claim.

2.2 Connection to the mains voltage
Attention! High touch current possible! Before connecting the power supply,
MAGIC EEC must be earthed.
For this purpose, the earthing cable must have a conductor cross-section of at least
2.5mm² if it is mechanically protected, or otherwise 4.0mm².
The following graphic symbols are located on the rear of the unit to indicate the
correct and safe use.
After plugging the power cable and switching on the device, the unit boots within
30 seconds.
An additional power supply socket for connecting an external 5 V power supply unit
is optional available.
