modules with G.703. 

Wetting current is a small amount of electrical current (60 to 140 milliamps) sent from the central office 
to the card to prevent the corrosion of electrical contacts in the module network connection.

The wetting current feature can be enabled or disabled by the end user. It is controlled by the location of 
a jumper on the J8 (CTLR 0) and J9 (CTLR 1) connectors on the network module. (See 

.)

To enable the wetting current feature, connect pins 1 and 2 on the J8 and J9 connectors with the jumper. 
To disable the wetting current feature, either remove the jumper completely, or use the jumper to connect 
pins 2 and 3 on the J8 and J9 connectors.

The card is shipped with the jumper connecting pins 2 and 3 on the J8 and J9 connectors, disabling the 
wetting current feature.
