5.29.5 Clock recovery
The data clock may be generated by the E-QUE card (Local Generated) or taken from the
T1 line. Normally the card should be set to ‘Line Recovery’ for connection to a third party
device or a T1 network. For other devices the clock source must be determined before
configuration. Select the correct configuration by clicking on the appropriate radio button.
If connecting two Eclipse HX matrices back to back using T1:
• An E1 or T1 crossover cable is required.
• One E-QUE card should be set to Local Generated clock and the other to Line
Recovery clock.
