Description

Adapters of Tau-PCI-E1 family are designed for use

in Intel-compatible computers with PCI bus for

directly connecting computers to E1 communication

links.An expansion card allows you to add two extra

links for connecting communication and terminal

equipment with RS-232, V.35, RS-530, or X.21

interfaces.

Tau-PCI-E1 multiplexer implements HDLC

synchronous protocol. Data are transmitted over a

direct memory access channel in master mode that

ensures an effective usage of computer input/output

bus.

Tau-PCI-E1 multiplexer has two data transmission

channels. Tau-PCI4-E1/V multiplexer has four

channels and consists of two cards: main adapter

card (Tau-PCI-E1) and expansion card (Delta).

Each serial channel of Delta expansion card provides

two interfaces: V.35 and RS-232. Switching between

Models

There are several models of the multiplexer:

• Tau-PCI-E1 - two channels with E1 interface.

• Tau-PCI-4E1 - four channels with E1 interface.

• Tau-PCI4-E1/V - two channels with E1 interface

and two extra channels with V.35/RS-232

interfaces.

• Tau-PCI4-E1/R - two channels with E1 interface

and two extra channels with RS-530/X.21

interfaces.

You can also order an expansion card separately:

• Delta – two channels with V.35/RS-232

interfaces.

• Delta/R - two channels with RS-530/X.21

interfaces.

Adapter Installation

Warning! V.35, RS-232, RS-530, and X.21

interfaces have no galvanic decoupling. To avoid

damage of your multiplexer and communication

equipment make sure that the housings of the

communication equipment and your PC are securely

connected to each other through grounded outlets

or with a separate wire, and there is no significant

potential drop between them.

Also, check if the power source of your PC has

enough power reserve for installing an additional card.

• Make sure that your PC is turned off!

• Remove the cover from your system unit, locate

an empty PCI slot, and demount the related stub

on the backside of the chassis.

• Before inserting the multiplexer into your PC set

jumpers of E1 line type selection for each channel

as required (see appendix).

• Insert the multiplexer into the slot up to the stop

and secure it to the backside of the chassis with

a screw.

• For Tau-PCI4-E1 model: locate another empty

slot, demount its stub, and insert an expansion

card into the slot. Make sure the card does not

touch any other parts within your PC and secure

it with a screw. Connect the main card to the

expander with a cable.

• Replace the cover of your system unit.

• Solder E1 lines to HDB-26 connector supplied

with the multiplexer. See Appendix for a list of

signals assigned to the connector pins. Use dry

flux when soldering for not to soil pins.

Adapter Testing

• Boot your PC from the floppy disk labelled "Diag

(Boot)". After the boot DIAG utility will start

automatically to search for installed adapters.

• Choose "General Test" from "Test" menu. This

will check main communication circuits of the

adapter (bus test) and then start an internal test

of all channels. The test should find no errors

(several CRC errors are only allowable in the

beginning of the test because of the sync

adjustment).

• To check external signal circuits go to "Channel"

menu, select the necessary channel number

("Select Channel..." row), connect an external

contactor (supplied with the adapter) to the

connector of the channel so selected, and launch

an external loopback ("External Loopback"

E1 Line Protection

Communication lines can be subject to pulse

interference from electrostatic and lightning

discharges, or other sources. If you are utilizing long

lines extending beyond a single building it is advisable

to use special safety devices (Communication Line

Surge Suppressors) which should be located in close

vicinity to your PC.

Devices with rated break-down voltage of about

7.5V and allowable pulse current of 200A having

small self-capacitance will fit to protect E1 lines.

Examples of such devices are D10B2 (for coaxial

cable) and D10BT (for twisted-pair cable) models

by TRIPP LITE company (U.S.A.).

row). When testing digital channels of Delta

expander make sure "Internal clock" sync method

is set. For X.21 interface, you should use "RS-

530" contactor.

• If the connected communication equipment

supports the loopback mode you can use the

latter for cable testing as well as for

synchronization instead of the contactor. To do

that switch the external equipment to the

loopback mode and start an external loopback

of the channel ("Channel" menu, "External

Loopback" row).

• "Setup" menu is used to change sync mode,

speed, test data type, etc. "Channel", "Adapter",

and "Test" menus are used to test single channels,

all channels of the same adapter, or all adapters

simultaneously.

Software Installation

The first (bootable) floppy disk supplied with the

adapter is intended to test the adapter. The second

floppy disk contains drivers for Linux and FreeBSD.

Installing Drivers in FreeBSD

and Linux OS

Drivers for Linux and FreeBSD are on the second

floppy disk. File readme.txt contains the full

list of the drivers. You can read files on the floppy

disk using "mread" utility (mtools package). Use "tar"

utility to unpack files. For example:

mread a:linx30.tgz .

tar xvzf linx30.rgz

After unpacking the necessary driver, follow the

installation instructions provided in readme.txt file (or

install.txt).

Configuring Channels in

FreeBSD OS

Use sconfig utility to set channel modes. Modes are

normally set at the start of the operational system

(e.g. from /etc/rc file) and do not need to be changed

afterwards. The full description of sconfig utility is

included in software package supplied, see "man

sconfig".

Configuring Channels in Linux

Use sconfig utility to set channel modes of Tau-PCI

adapter in Linux OS. Create a batch file that sets

channel modes at the start of the operational system

using examples provided in the distributive package.

For help on sconfig utility use the following command:

Tau-PCI-E1 could be configured by the software

for three modes of operation. These modes

interrelates physical and logical channels.

ConfigurationA: Dual E1 access unit. E1 Link 0 and

E1 Link 1 operate independently and have identical

data pathes to the PC memory. Data transfer rate is

determined by the number of timeslots used (fig. 1).
