14 Staring Up
Device connection to the network or device under testing (NUT/DUT) using
one port is schematically shown at figure 3.1. In this case, traffic generated
by testing device should be redirected back by means of loopback.
In case networks or devices under testing are able to redirect traffic from
one port of B4-GBE card to its another port, a connection scheme is used
that is shown at Figure 3.2.
When two Bercut-MMT devices are used for remote testing of networks
or devices, (refer to Figure 3.3), it is necessary to perform configuration,
described in Annex A, p. 69.
3.2 Operation Mode Selection
The mode of operation of data transmission interface analysis card can be
configured with the help of
Firmware Update utility application: O-
Menu
⇒

⇒
Firmware Update utility (for detailed description of
operation mode configuration for pluggable modules refer to

operations manual. Telecommunication Systems Universal Analyzer Plat-
form ).
3.3 Connection device to Network Interfaces
• Install the B4-GBE card according to description in Operations Manual .
• Install SFP modules in the card interface ports, up to click.

• Connect device to the network equipment to be tested according to
Connection diagrams shown above.
After the device is connected to equipment to be tested, it is necessary to
configure measurement parameters, that are described in details in section 4,
p. 17.
3.4 Network Interfaces State Indication
For B4-GBE cards, network interfaces state indication is provided by LEDs
at the
Bercut-MMT front panel. In the upper part of a screen there are
LED labels.
