Interfaceslot. This same card supports the Attendant Console data link.
l This card provides the digital data link channel connection to
the system.
l The data link is full-duplex, 1,200 baud, 20 ma current loop in
serial form.
l The BLDU can connect to one port on an 
ATT12 card, and an
Attendant Console can connect to the other 
ATT12 port. Up to

the data link in service or out of service. If remote applications
require, the standard type of data link used is compatible with
readily available equipment designed for this application. Since
this type of installation depends...

TL-130500-1001BLDU16.5 The BLDU is powered from either a 24-VAC transformer
Powerconnected to a 115 VAC power source or from a -48 VDC
power supply. See TL-130300-1001 for power connections for
the BLDU. TL-130100-1001 describes the operations that can
be executed from the BLDU.
