Digital Extension Card

IP Office Digital Extension Card

At time of purchase, an IP500 V2 control unit, the base unit of the IP Office system, will be configured by your telephone system company to your specifications. This is typically done using cards or combination of cards, the building block of the IP500 V2 hardware unit. An IP Office digital extension card is one such card; in this case it is the internal unit which allows digital handsets to be fitted onto the IP Office phone system.

The IP Office Digital Extension Card (Digital Station 8 Card) provides 12 RJ45 ports: the first 8 ports are DS ports for the connection of AVAYA digital phones other than IP phones. The card can be fitted with an IP Office 500 daughter trunk card, which then uses the additional 4 RJ45 ports for trunk connections.
