Bit Error Ratio in the presence of
an Interfering Signal (IS) at
LIN+,LIN-
IS is a sinusoidal tone, 22.368 MHz
for DS3 or 25.92MHz for STS-1. Data
is a PRBS15 (2
-1) pattern. IS power
is 10dB below data signal power.

Note 5:
Signal source should meet DS3 template of ANSI-T102.1993 Figure 4 and STS-1 template of ANSI-
T102.1993 Figure 5, Loss characteristics of the WE728A or RG 59B cable should be better than Figure
C2 of ANSI-T102.1993.
Note 6:
Receiver can handle up to 450 feet of cable loss (5.5dB) from the DSX cross-connect.
Note 7:
Case where test signal is fed directly into receiver with fast rise times violates DS3 template and normal
maximum. In this mode no noise, jitter, or interfering tone impairments will be added.
Note 8:
This is performed in digital loop-back mode. Jitter is supplied by a Bit Error Rate Tester and bit errors
are measured. Jitter is specified in terms of UI (Unit Interval) and frequency, is summed with DS3
PRBS15 data through 450 feet of cable.
