Notes:
1. The typical RCVR thresholds listed above are for non-standby or hot-standby with space diversity configu-
rations. For hot-standby configurations, deduct 1 dB for the A side and 10 dB for the B side.
2. RCVR thresholds and dispersive fade margins are typical values. Guaranteed values are 2 dB worse.
Receiver DADE Automatic, range Not Less Than ±300 ns
CEPT INTERFACE (E1) REQUIREMENTS
Line rate 2.048 Mb/s ±50 ppm
Line code High density bipolar with 3 zeroes maximum (HDB3)
Line impedance 120 ohms nominal, line-to-line
Pulse Shape Refer to CCITT G.703, Section 6.
Pulse width 244 ns, nominal
Interference 18 dB without affecting error-free performance
Jitter tolerance 1.5 unit intervals peak-to-peak (UI p-p) from 20 to 2400
Hz, falling at 20 dB/decade to 0.2 UI p-p at 18 kHz,
and continuing at 0.2 UI p-p from 8 to 100 kHz
Intrinsic jitter 0.2 UI p-p, 10 Hz to 100 kHz; 0.05 UI p-p, 18 to 100
kHz
Jitter transfer Jitter gain will not exceed 0.5 dB from 1 Hz, and will not
exceed a gain line from 0.5 dB at 40 Hz falling (at 20
dB/decade) to -19.5 dB at 400 Hz.
