Digital Station Boards
Digital Telephone Interface Board (DTIB)
The DTIB board provides the circuitry to support 12 digital phones.
This board plugs into any peripheral slot.
The station connections are via one 50-pin female (amphenol type) connector located on
the front edge of the card.
The board has two LED indicators for status. One LED for the DTIB status, one LED for the
DTIB-E status.
A Normal/Service switch located toward the top of the card allows the card to be inserted
or removed from the system while under power and also can be used to disable all
station circuits on the card.
The ejector tabs are color coded green.
