The RBS can supply transmission equipment with +24 V DC. The maximum
power output is 250 W.
8 Transmission
The RBS 2206 is normally connected to a DF for transmission (PCM lines).
Four PCM cables are connected to the ports on the front of the DXU. The RBS
2206 supports two transmission standards:
• T1 1.5 Mbit/s, 100
, with PLM synchronisation
• E1 2 Mbit/s, 75 , with PCM synchronisation
• E1 2 Mbit/s, 120
, with PCM synchronisation
PCM Overvoltage Module
This module contains overvoltage protection for the PCM lines. If the PCM lines
are terminated in equipment outside the RBS equipment room, these lines must
be protected by OverVoltage Protectors (OVP) in the DF.
Optional Transmission Equipment
The cabinet can be connected to optional transmission equipment that is
mounted externally. The optional transmission equipment used is:
• Transmission adapter (not connected to DF) with BNC connector
• DXX (installed in the OXU)
• Mini-link
• Mini DXC (installed in the OXU)
