Features

The CC-2M has the following characteristics:


Transmission speed is 512 kBit/s via the FO interfaces FO1/LWL1 and/or FO2/LWL2 with
ST-connectors (820 nm) at synchronous mode.

Transmission speed is 1.2 kBaud to 115.2 kBaud via the FO interfaces FO1/LWL1 and/
or FO2/LWL2 with ST-connectors (820 nm) at asynchronous mode. e. For an asynchro-
nous connection the transmission rate is 1.2 kBaud to 115.2 kBaud.

Connections to the protection device or device with serial interface via a interference free
fibre optic cable to a FO module integrated there.

Maximum fibre optic cable length for the connection between protection device and
CC-2M 1.5 km (0.93 mile) with 62.5/125 µm or 50/125 µm multi-mode fibres. Connection
with ST-connector.

Data connection to the communication device:


Maximum line length for the connection between E1/T1 transfer point (SDH / PDH-Network)
and CC-2M 40 m (131 ft).
Note
Protection devices are often mounted in an environment with increased EMC load. To
warrant an interference-free transmission of the electric signals, install the CC-2M in the
communication cabinet at the shortest distance to the communication-network connection
(DCE, multiplexer).
