D-channel. The MegaBERT expands the bandwidth to 2 Mbit/s - to either 2048 kbit/s (framed) or 1984 kbit/s in time slots 1-31 (2 Mbit unframed). Last but not least, the ARGUS can run a BERT to a remote loopbox or perform an end-to-end measurement to another ARGUS. - Page 6 Performs a BERT in an extended call to itself, via a loopbox or in end-to-end operation. The ARGUS will, if needed, handle the loopbox function itself. The optional MegaBERT extends the bit error test on E1/PRI accesses to a full 2 Mbit/s bandwidth....

Page 15: Connection For A Pri Network
3.1 Pin Assignment on the ARGUS (BRI/PRI/E1) In TE mode, the ARGUS sends on lines 4 and 5, in NT-Mode on 1 and 2 (see illustration). An adapter cable, which is suitable for the PRI network/system to be tested, can be connected using the RJ45-RJ45 adapter. -
Page 16: Operation On A Pri Access
Use the included connection cable to connect the ARGUS "BRI/PRI/EI" jack to the access to be tested and then switch the ARGUS on. The PRI settings are made in chapter 2 Configuring accesses page 7. In this example the PRI TE mode was selected. -

Page 36: Test
In the case of a manual test, the ARGUS will setup a D-channel connection and an X.31 connection. The duration of this connection is determined by the user (or the remote end). For the duration of the connection, the ARGUS will repeatedly send a predefined data packet. - Page 37 Default setting: 10 Entry (from the keypad) of the TEIs (Terminal Endpoint Identifier) to be used in the X.31 test.

The ARGUS checks all of the TEIs from 0 to 63 one after the other. All the TEIs, which support X.31service on Layer 2, will be displayed. - Page 41 X.31 cause for the failure (in the example above: 512) and the associated diagnostic code if there is one.
