The MAGIC EEC allows the converting of ETI to EDI and EDI to ETI signals. Typical applications are headends with DAB modulators which do not yet support EDI and modern Ensemble Multiplexers which already provide an EDI output signal (e.g. Fraunhofer ContentServerTM). Due to the converter the contribution to the transmitter can be realised via E1 lines using the ETI format despite the EDI output of the Multiplexer. Another example are headends with Ensemble Multiplexers, which have only ETI inputs and outputs (e.g. Rohde & Schwarz DM001), but where the contribution is possible only via IP networks using the EDI protocol.

 

Interfaces

MAGIC EEC has one G.703/G.704 input and output for ETI. Additionally, two LAN interfaces are available. The functions of the LAN interfaces (configuration monitoring, SNMP and EDI input/output) can be freely programmed according the users requirements. Optionally, an ETI monitoring output can be equipped. Alternatively to the second ETI module, a LAN3/4 Upgrade is available to add two further LAN interfaces so that in total 4 are available.

Configuration

The system can be configured with the Windows PC Software included in delivery. Via the Windows PC Software the status of the ETI or EDI input streams as well as all system parameters are displayed in a clear and user-friendly way.

Further Features

  • Integrated Logfile
  • SNMP v1/v2 to integrate the system in up to four network management systems
  • Eight potential-free and programmable relay contacts
  • Eight programmable TTL GPIO contacts
  • Clocks: 1 PPS and 10 MHz/2,048 MHz (selectable)
