Note 1: 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.  
Note 2: 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.  
Note 3: 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.  
Note 4: In this mode, no noise, jitter, or interfering tone impairments should be added for guaranteed receiver  
performance.  
Note 5: Interfering signal is a non-synchronous sinusoidal tone of 22.368MHz for DS3 or 25.92MHz for STS-1.  
Data is a PRBS15 (215-1) pattern.
