E1 Interface

Line Rate:

2.048 Mbps, ± 50 bps (± 200 bps VCO lock range)

Line Code:

Bipolar AMI or HDB3

Line Impedance:

120 Ohms (balanced) or 75 Ohms (balanced or unbalanced)

Minimum Pulse Density:

Zero code suppression via HDB3 coding

Frame Format:

Unframed, 32-channel (G.703). Framed: 30 or 31-channel CEPT

 

multiframe per ITU-T G.704.

VF Signalling:

CAS or CCS

Max. Line Lengths:

E1 output complies with G.703, so cabling must not exceed

 

–6dB/1000 feet at 1024 kHz (applies to 75 Ohm coax or 120 Ohm

 

twisted pair up to 350 meters or 1000 feet). StrataCom supplies

 

cable with a maximum attenuation of 7 dB /1000 ft., so the

 

maximum length of this cable is 850 feet (260 meters).
