Description
Tau-PCI/32 adapter is a multiplexer/cross-connector with two E1 ports and 32 built-
in HDLC controllers. The adapter is installed in a computer with a PCI bus. The
Tau-PCI/32-Lite is a light version, has one E1 port and a compact design that allows it to
be installed in a Low-Profile PCI.
