E1R2 coax trunk cards must be grounded correctly and require the IP Office control unit to be connected to a protective
ground . Normally the ends of one connection is grounded. For example, if the exchange Tx1 is grounded, the IP
Office Rx1 should also be grounded. However this must be confirmed with the line provider to establish which ends they
want grounded.

(C) to the chassis with the long securing screw also supplied with the card.
2.Use the two jumpers supplied with the card, match the ground selection of the line provider. For example, if the line
provider has grounded their Tx1, place a jumper across the two Rx1 pins of jumper block J6.
