Functional Description

Possible ways of using the SWT 3000

Analog transmission path

Figure 8:
Examples 1 and 2:
Pilot cable connections. For operation via pilot cable, two SWT 3000 devices can be linked di-
rectly through the analog inter faces (CLE).
Example 3:
The analog link (CLE) between two SWT 3000 devices can also be a PLC link. Depending on de-
vice configuration, SWT 3000 can be used with PowerLink in alternate multipurpose, simultaneous
multipurpose or single-purpose mode.
Example 4:
Fiber optic connections between SWT 3000 and PowerLink. A short-distance connection between
an SWT 3000 and Siemens' PowerLink PLC terminal can be realized via an integrated fiber optic
modem. In this case an SWT 3000 standalone system provides the same advanced functionality as
the version integrated into PowerLink. Each PowerLink can be connected to two SWT 3000 de-
vices via fiber optics.

Digital transmission path

Figure 9:
Examples 5,6,7:
SWT 3000 digital connections. The digital interface (DLE) permits protection signals to be trans-
mitted over a PDH or SDH network.
