Setting Jumpers on the 2-Port FXO Card

Note This information does not apply to the VIC2-2FXO card.

The FXO voice interface card includes two jumper headers, W3 and W4, to set loop-start or ground-start

mode. One jumper configures each FXO port. The default setting is loop-start, which should be

satisfactory in most installations. In this setting, jumpers are placed over positions 2 and 3 of headers

W3 and W4.

Most modern central office equipment, such as DMS-100 and 5ESS switches, provides calling party

control (CPC) and Ring on Seize on loop-start lines. CPC allows quicker disconnection, and Ring on

Seize minimizes glare (collision of inbound and outbound calls on the same interface).

If your central office does not provide these features on loop-start, you may want to configure the FXO

card for ground-start operation instead by moving the jumpers to positions 1 and 2.

For proper operation, both jumpers on the VIC-2FXO card must be configured identically.

Note This setting does not apply to VIC-2FXO-EU and VIC-2FXO-M2 interface cards.
