8.4 E1 Trunk and Direct Modes
The E-QUE interface can be used for both direct E1 to E1 port connections or to provide
trunk linking via a network between systems. The E1 connections can be made between
Eclipse systems or between Eclipse systems and compatible third-party equipment. E1
mode provides 30 channels of G.722 or G.711 encoded audio available on each of ports 1
and 5, giving 60 channels per card.
The E1 specifications are:
• HDB3 Encoding.
• Long Haul Receive Signal Level.
• E1 120 Ohm Transmit Pulse Amplitude.
• Balanced.
• 120 Ohm Line Impedance.
• No Signaling.
• G.722 or G.711 64 kbit/s Audio Encoding.
• Tx Clock locally generated.
• Rx Clock Line Recovered.
Figure 36: Matrix to Matrix direct E1 Trunking shows E1 trunking using a direct connection
between the matrices using a CAT5 crossover cable. The E-QUE interface should be set to
E1 Direct in EHX hardware setup.
