E1 Trunk Connections

You can use the E-QUE interface card to make E1 connections between Eclipse systems or between Eclipse systems and compatible third-party equipment.

E1 mode provides 30 channels of G.722 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 64 kbit/s Audio Encoding.

  • Tx Clock locally generated.

  • Rx Clock Line Recovered.

The following image shows Matrix to Matrix direct 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.

E1 trunking between matrices can also be achieved over an E1 network, as shown.

For EI Trunking with an E1 Network, E1 ports 1 and 5 of the E-QUE interface are connected using standard straight-through CAT5 cables rather than crossover CAT5 cables.

The E-QUE interface can also be used to connect the matrix to third party equipment using E1 port 1 or 5.

The CAT5 cable connecting the E1 port on the E-QUE rear card may be a crossover cable or a straight-through cable depending on the requirements of the third-party equipment. The E-Que interface should be set to Direct in EHX.
