Description
The 3.3V Multiple Rate Digital Switch (MT89L86) is
pin compatible with MITEL’s 5V MT8986 and retains
all of its functionality. This 3.3v device is designed to
provide simultaneous non-blocking connections for
up to 256 64kb/s channels or blocking connections
for up to 512 64kb/s channels. The serial inputs and
outputs may have 32 to 128 64kb/s channels per
frame with data rates ranging from 2048 up to 8192
kb/s. It also provides per-channel selection between
variable and constant throughput delays allowing
voice and grouped data channels to be switched
without corrupting the data sequence integrity.
