QUAD FEEDER POWER SUPPLY
SUPPLIES POWER FOR UP TO FOUR DIGI-
TAL TELEPHONELINES
CONFORMS TO THE CCITT RECOMMEN-
DATIONS FOR POWER FEED AT THE S OR
T REFERENCE POINTS
SUPPORTS POINT-TO-POINT AND POINT
TO MULTIPOINT CONFIGURATIONS
EACH OF THE FOUR LINES IS INDIVIDU-
ALLY CONTROLLED
HIGH-VOLTAGE BCD TECHNOLOGY SUP-
PORTING UP TO -130V
AUTOMATIC THERMAL SHUTDOWN
STATUS CONDITION DETECTION (BY MI-
CROPROCESSOR) FOR EACH LINE:
– Lowoutput voltage
– Openloop
– Current overload
– Thermaloverload
– Normal line condition
PROGRAMMABLE CURRENT LIMITING
OUTPUT CURRENT UP TO 120mA
DESCRIPTION
The ISDN Quad Feeder Power Supply (IQFPS)
provides a power source for up to four line inter-
faces. The power source to the device is a local
battery or a centralizedregulatedpower supply.
It can operate in point-to-point and point-to-mul-
tipoint configurations as far as S interface is con-
cerned.
By the device microprocessor interface, each
powered line is individually controlled and moni-
tored.
Therefore,overloads and faults are easy to detect
and localizeeven in a large system.
The status conditions detected by the device on
each line that may be read by the microprocessor
are :
low output voltage
openloop
current overload
thermaloverload
normalline conditions
A hardwarecurrent limiting programmable feature
is available.
