Installation
The VoIP card can be placed in slots 1-7 of Cabinet 0 and in slots 0-7 of Cabinet 1, 2, and 3.
Once the slot is identified, it takes the required time slots and deducts them from the
available ones. If more then one card is identified, each card is identified in the same manner
and it requires its own unique IP address.

There are six indicator LEDs that signal the status of the LAN Ethernet connection properties.
The Ethernet port auto-negotiates connection speeds and duplexing which is indicated by

The VoIP card is a combination card that has both IP Trunks and station ports. If a VoIP card
is installed in any slot prior to a station-related slot, the station numbering plan will be
affected. In the event that VoIP installation causes undesired effect to the station numbering
plan, use FLASH 52 to revise the plan as desired.
