The capacity agile version, MMU 2x2 – 34+2, can be run at all traffic capacities
covered by t he MMUs with fixed capacities. The MS M software (≥ version
6.0) is used to set the traffic capacity locally on site. Consequently, the traffic
capacity of a terminal can be changed without replacement of M MU hardware.
3.8.1 Functio nal Blocks
The following functional blocks are i ncluded in the MMU:
• Traffic interfaces and router
• 2/8 multiplexer/demultiplexer (MMUs 4x2/8 Mbit/s only)
• Radio frame multiplexer/demultiplexer for traff ic and ser vice channels
insertion/ extraction and Forward Error Correction (FEC) encoding/decoding
• Transmitting and receiving signal modulation/demodulation
• Cable interface with the radio unit
• Control and supervision processor
