E1 TRUNK AND DIRECT MODES

The E-Que card 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 encoded audio are available on each
port, 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 Signalling
• G.722 64 kbit/s Audio Encoding
• Tx Clock locally generated
• Rx Clock Line Recovered
Figure 4-6 shows E1 trunking using a direct connection between the
matrices using a CAT5 crossover cable. The E-Que card should be
set to "E1 Direct" in ECS Matrix Hardware setup.
