Table 2-2. E1-Related Telecommunications Specifications
ITUT G.703 Physical/Electrical Characteristics of G.703 Hierarchical Digital Interfaces
Defines the 2048kbps bit rate: 2048 ±50ppm. The transmission media are 75 coax or 120 twisted pair; peak-to-
peak space voltage is ±0.237V; nominal pulse width is 244ns.
Return loss: 51Hz to 102Hz is 6dB, 102Hz to 3072Hz is 8dB, 2048Hz to 3072Hz is 14dB
Nominal peak voltage is 2.37V for coax and 3V for twisted pair.
The pulse mask for E1 is defined in G.703.
ITUT G.736 Characteristics of Synchronous Digital Multiplex Equipment Operating at 2048kbps
The peak-to-peak jitter at 2048kbps must be less than 0.05UI at 20Hz to 100Hz.
Jitter transfer between 2.048 synchronization signal and 2.048 transmission signal is provided.
ITUT G.742 Second-Order Digital Multiplex Equipment Operating at 8448kbps
The DS26303 jitter attenuator is compliant with jitter transfer curve for sinusoidal jitter input.
ITUT G.772
This specification provides the method for using receiver for transceiver 0 as a monitor for the rest of the seven
transmitter/receiver combinations.
ITUT G.775
An LOS detection criterion is defined.
ITUT G.823–The control of jitter and wander within digital networks that are based on 2.048kbps Hierarchy
G.823 provides the jitter amplitude tolerance at different frequencies, specifically 20Hz, 2.4kHz, 18kHz, and
100kHz.
ETSI 300 166
This specification provides transmit return loss of 6dB for a range of 0.25fb to 0.05fb, and 8dB for a range of 0.05fb
to 1.5fb where fb equals 2.048kHz for 2.048kbps interface.
ETSI 300 233
This specification provides LOS and AIS signal criteria for E1 mode.
Pub 62411
This specification has tighter jitter tolerance and transfer characteristics than other specifications. The jitter transfer
characteristics are tighter than G.736 and jitter tolerance is tighter then G.823.
