with on-board voiceband codecs, or other 3.3V voiceband
codec devices.
The ISL5586 provides on board ringing signal generation up
to 95V peak supporting sinusoidal or trapezoidal
waveshapes with DC offset. Loop start and ground start
trunks are supported, and an open circuit DC voltage of less
than 56V is maintained on the subscriber loop in the on-hook
condition, in compliance with MTU operation and the safety
requirements of UL-1950.
Together with the Broadcom BCM3352, the ISL5586
provides resistive and complex two wire impedance
matching and transhybrid balancing. Also supported are on-
hook transmission of caller id signals, soft and hard polarity
reversal and 12/16kHz subscriber pulse metering systems
used in Europe and Asia, thereby allowing a low cost, low
risk, global product design to be achieved.
