1. The following BERT settings are available only on the four-port HSU 530/35 Card:
ds0, ff, 7e, 32, 40, ocu-a, dsu-a, csul-a, and csu2a. These settings are not available on
the HSU-T V11 and HSU-T 35 Cards.
BERT
The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected HSU port. The patterns that can be selected are off, mark (1111), space (0000),
1:1 (1010 alternating), 1:7 (0100-0000), 511 (511 test pattern), qrss (quasi-random signal
source), and 2047 (2047 test pattern).
On the four-port HSU 530/35 Card, selecting the ds0 pattern will display another set of BERT
patterns. Additional non-latching loopback patterns are ff (1111-1111), 7e (0111-1110), 32
(0011-0010), 40 (0100-0000), ocu-a (ocu-alternating byte), csu-a (csu-alternating byte),
dsu-a (dsu-alternating byte), csu1a (csu–one repeater–alternating byte), and csu2a (csu–two
repeater–alternating byte). The results of the alternating patterns (ocu-a, csu-a, dsu-a, csu1a
and csu2a) appear in the Test Screen.
Also note that the Bit Error Rate Tester is supported on the HSU-T V11 and HSU-T 35 Cards
only if the port mode is set to dce in their Card Main Screens.
