OCTAL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
REV. 1.0.2
Once the T1/E1 input signal has been normalized to 0dB by adding the maximum gain (+29dB), the receiver
will declare RLOS if the signal is attenuated by an additional -9dB. The total cable loss at RLOS declaration is
typically -38dB (-29dB + -9dB). A 3dB hysteresis was designed so that transients will not trigger the RLOS to
clear. Therefore, the RLOS will typically clear at a total flat loss of -35dB. See Figure 7 for a simplified diagram.
Setting the Receiver Inputs to -36dB T1/E1 Long Haul Mode
By setting the receiver inputs to -36dB T1/E1 long haul mode, the equalizer will detect the incoming amplitude
and make adjustments by adding gain up to a maximum of +36dB normalizing the T1 input signal. This setting
refers to cable loss (frequency), not flat loss (resistive). Once the T1/E1 input signal has been normalized to
0dB by adding the maximum gain (+36dB), the receiver will declare RLOS if the signal is attenuated by an
additional -9dB. The total cable loss at RLOS declaration is typically -45dB (-36dB + -9dB). A 3dB hysteresis
was designed so that transients will not trigger the RLOS to clear. Therefore, the RLOS will typically clear at a
total cable attenuation of -42dB. See Figure 8 for a simplified diagram.
E1 Extended RLOS
E1: Setting the Receiver Inputs to Extended RLOS
By setting the receiver inputs to extended RLOS, the equalizer will detect the incoming amplitude and make
adjustments by adding gain up to a maximum of +43dB normalizing the E1 input signal. This setting refers to
