signal), b1eoc (an eoc loopback on B1), b2eoc (an eoc loopback on B2), 2beoc (an eoc
loopback on both B-channels) and bdeoc (an eoc loopback on both B-channels and the
D-channel).
If the LB GEN option (on the previous screen) is set to ta, the U-ST field must show actv
before any loopbacks selected become operational.
LB ST
The Loopback State (LB STATE) field indicates the local loopback selected on the main
screen for this port. This field will show off, ta, or net. Since this is an information-only field,
there are no user-selectable parameters.
SEAL
The sealing current field indicates whether the sealing current option is selected or not. This
only applies to the BRI-U*8, BRI-SC U*8, BRI-2 U*8-SC and BRI-2 U*8 cards.
CRC-TEST
The CRC-Test tells the user whether the CRU test for LULT and LUNT is in progress or not.
This is a read only field and the possible values are YES or NO. When the CRC test is in
progress the LT may receive corrupted data blocks. CRC Test parameter is available when in
LUNT or LULT mode. This only applies to the BRI-2 U*8-SC and BRI-2 U*8 cards.
5.3.15 Performance Data Screen
The BRI U*8 and BRI-SC*8 cards support proprietary performance data monitoring, which
continuously measures operation performance of the connection from the system unit to the
NTU.
To get performance data for a particular port, highlight the port in the BRI Card Main Screen
and press “p” (Perf). The Performance Data Screen shown in Figure 5-19 will appear for the
BRIU*8 and BRI-SC U*8 cards. Table 5-26 lists the actions you can perform for the BRI U*8
and BRI-SC U*8 cards form the bottom line of the screen.
While viewing the Performance Data Screen, press “r” (Refresh) to obtain updated
information.
