Tau-PCI/32 Adapter, User Manual The Tau-PCI/32 adapter is primarily used in the construction of data transmission networks based on E1 channels, and for the creation of specialized E1 flow processing equipment (telephony, signaling). The adapter delivery set includes operating system drivers that implement the primary operation modes of the adapter, which are enough to construct data transmission networks.

Adapter Tau-PCI/32, User Manual The transceiver provides exchange (reception/transmission) of information between the “logical channels” and RAM via the PCI bus. The logical channels of the transceiver are formed from the predefined E1 timeslots. Each timeslot can be "connected" to only one logical channel. This allows up to 32 logical channels to be obtained.
Tau-PCI/32 Adapter, User Manual Not all of the 32 transceiver timeslots are used in the unstructured bit rate slow-down modes. The control modules are assigned to timeslots that should be used, and their number must correspond to the speed selected. The indicated timeslots are disconnected from the cross connector, and are only used by the unstructured mode modules.
Adapter Tau-PCI/32, User Manual Adapter Check The adapter delivery set includes two 3.5” floppies or a CD-ROM. If floppy disks are included, boot up the computer using the “Diagnostic Boot” floppy, otherwise boot up from the CD-ROM. After the boot, a diagnostic application that will start automatically will search and perform basic testing of the internal circuits (bus test) of the installed adapters. Then, you choose the adapter that needs testing.
Tau-PCI/32 Adapter, User Manual Adapter Configuration in Linux After the kernel modules (drivers) are assembled and installed, a startup module launch and channel configuration command file will also be installed. Because different Linux clones use a distinct startup procedure, for some systems this command file has to be installed manually (also, modification of the command file itself may be required). When prepared command file is used, to change the channel operation parameters the /etc/cronyx.
