E3/DS3/STS-1

Transceiver

DS3/STS-1 RECEIVER (RFO = 5.23KΩ FOR DS3 AND 4.53KΩ FOR STS-1, E# PIN IS SET HIGH OR

ALLOWED TO FLOAT), INPUT IS TRANSFORMER COUPLED

Bit Error Ratio in the presence IS is a sinusoidal tone, 22.368 MHz

10-9

of an Interfering Signal (IS) at for DS3 or 25.92MHz for STS-1. Data

LIN+,LIN-

is a PRBS15 (215-1) pattern. IS power

is 10dB below data signal power.

Note 3: 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 4: Receiver can handle up to 450 feet of cable loss (5.5dB) from the DSX cross-connect.

Note 5: Case where test signal is fed directly into receiver with fast rise times violates DS3 template and normal

maximum. Interfering signal performance is not guaranteed in the presence of DS3 High at the input..
