TCU 02

This is basically a SIU 02 re-packaged from 1U into the RBS6000 form-factor.



It uses the same connector like e.g. the DUL 20 or DUG 20 units.


This is an RJ45 Ethernet port.

It is configured to a fixed IP address of and provides telnet + SSH access.

The default user name is admin; the default password is hidden.

You will get access to a command line interface:

Connected to
Escape character is '^]'.

login: admin
STN CLI - ready


The external clock port is labeled "GPS", and is now a 8-pin GPS connector similar to the DUL 20 or DUS 20 and connects to a GPS 02. This instead of 10-pin SYNC connector as on the SIU 02.


There are 8 E1/T1 ports, on 4 RJ-45 connectors. Same dual E1/T1 pinout as DAHDI cards.

Pinout TODO

Transport Network

  • 4x RJ45 Ethernet
  • 4x 1G SFP cages for the Transport Network (TN).

The ports are combo, ie, you must choose a RJ-45 OR SFP (max 4 TN ports active).
