2.3 INTERFACE CARDS

UNI CARD

These cards provide the interface connections for telephone lines and stations to the KSU. These cards fit into the

universal card slots to configure the system as required.

The UNI card can be installed in any of the two universal slots of the OfficeServ 7100 system. The UNI card is used

to accommodate other optional daughter boards. Any combination of the 4DLM, 4SLM or 4TRM modules can be

installed in any of the three slots on the UNI card for a total of 12 ports per UNI card. This type of slot configura-

tion allows the customers to grow or expand in 4 port increments. Customer can start out and configure the sys-

tem as a 4 line by 8 station system and later expand to a 8 by 16 configuration and beyond.

Each slot can be used as a voice trunk line board or voice station board depending on the mounted option board.

If a 4TRM option board is mounted in the UNI board, it operates as a voice trunk line board. If 4SLM and 4DLM

option boards are mounted, it operates as a voice station board. The UNI card is not hot swappable. This card can

not migrate to the OfficeServ 7200 or OfficeServ 7400 systems. See installation manual for details.
