DS3/STS-1 -- RECEIVER SPECIFICATIONS (Transformer-coupled)
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 RG59B cable should be better than Figure
C2 of ANSI-T102.1993.
Min spec corresponds to minimum DSX amplitude, 5.5dB of cable loss (450ft) and 6dB of flat
attenuation. Error-free receiver performance is guaranteed for up to 600ft of cable from DSX cross-
connect. Typical part can handle up to 900ft.
Min spec corresponds to amplitude of 425mVpk at DSX, 5.5dB of cable loss (450ft) and 20dB of flat
attenuation. In monitor mode, interfering tone performance is not guaranteed.
In this mode, no noise, jitter, or interfering tone impairments should be added for guaranteed receiver
performance.
Interfering signal is a non-synchronous sinusoidal tone of 22.368MHz for DS3 or 25.92MHz for STS-1.
Data is a PRBS15 (2
15
-1) pattern.
