USER GUIDE

This User Guide gives quick set up information. For more

detailed information, the LINKSTREAM Range Reference

Manual is available.

The LINKSTREAM is a stand alone product combining

the functions of a terminal server and router in the same

unit. It consists of a metal case with an internal power

supply with 8 asynchronous ports. In addition, there is

an Ethernet port and two WAN interface connections.

The LINKSTREAM function is primarily that of a

distributed data switch working at both the wide and local

area network level. LINKSTREAM combines a host of

features providing the user with two high speed link ports

to access remote local area networks, eliminating the

need for additional bridges and routers. The two high

speed link ports operate at speeds up to 2Mbps enabling

the user to perform remote terminal multiplexing

accommodating Nx64K digital services.

LINKSTREAM is supplied in packaging specially designed

to prevent damage during transit. It is important that

the contents are checked against the list below BEFORE

installing. In the unlikely event of a damaged or missing

item please contact your supplier.

USER GUIDE

The LINKSTREAM consists of a stand alone case of metal

construction with an internal power supply. Up to two

expansion cards can be fitted to provide additional user

channels, up to a maximum of 24.

The unit is supplied as standard with the following

features:

2 x Serial (WAN) ports

8 x Asynchronous user channels

3 x Ethernet LAN ports 10Base5, 10Base2 and 10BaseT.

Optional upgrade modules are available and are detailed

later in this section.

The front panel of the unit is shown below.

RUN

A green LED which flashes at a constant rate of approx.

once every second. This indicates that the power is

applied, all self checks are completed and the unit is

running normally.

LNK0

A green LED which flashes to show data transfer over

Link0. When data transfer ceases, the LED may be left in

the ON or OFF condition.

LNK1

A green LED which flashes to show data transfer over

Link1. When data transfer ceases, the LED may be left in

the ON or OFF condition.

For data transfer over the ISDN the appropriate link LED

will be permanently on.

ENET

A green LED which flashes to show data transfer over the

Ethernet interface. When data transfer ceases the LED

may be left in the ON or OFF condition.

ATTN

An amber LED which when illuminated indicates that a

fault is present or has occurred during system operation.

If lit, please contact your supplier for assistance. If unable

to do this, the fault may be due to a corruption in the

unit's configuration and it is advised that a cold start is

activated and the unit re-configured.

There are also two recessed push buttons on the front

panel:

RSET This performs a 'warm start' to the system in

that it clears down all queues and restarts the

system with existing configuration parameters.

RSRT This button is used to perform a full 'cold start'

and is used in conjunction with RSET.

The ISDN function within LINKSTREAM has been designed

to offer the same operation to the user whether the

internal ISDN module is installed or an external Terminal

Adaptor is connected to the LINK0 or LINK1 interface.

Stand alone and rackmount units are supplied with 8 user

channels. Up to 24 user channels can be supported by

the addition of LINKSTREAM expansion cards. These are

ordered separately and are fitted by the user.

The LINKSTREAM VIP card provides 2 compressed voice/

fax channels for IP networks.

On power up, the LEDs on the front panel illuminate while

the LINKSTREAM performs system checks. Once

successfully completed the RUN LED flashes at a constant

rate (approx. once every second).

If the RUN LED does not flash at a constant rate, or the

ATTN LED is on, then do not continue with the

installation. Contact your supplier for advice.

Connect the RJ45 end of your console cable into any of

the user channels. Connect the other end of the console

cable into the serial port of your computer or terminal,

tighten the locating screws where applicable.

To make up your own console cable the RJ45 socket pin

outs are detailed in the 'User Channel Connection' section,

below.

The user channel RJ45 sockets present asynchronous

V.24/V.28 as a DCE with the following pin outs :

2 <<-- 20 DTR

8 -->> 5 CTS

Please ensure that user channel cables do not exceed V.24/

V.28 (RS232) recommended lengths or data corruption

can occur.

The following cable specification is typical to allow

bidirectional modem access. We recommend that you

check with your modem manual to ensure that the

specification is suitable.

The user channels on LINKSTREAM have 5 control lines

for modem access, 3 outputs (DCD, DSR, CTS) and 2 inputs

(RTS, DTR). The 2 inputs are monitored for call status

whilst 2 outputs (DCD and CTS) are used by LINKSTREAM

to control access. DSR is permanently 'ON' by being tied

high through a resistor.

LINKSTREAM is capable of working in 3 different modes

with a modem to suit every application :

1. Initiate call only (Dial Out)

2. Receive calls only (Dial In)

3. Bidirectional calls (Dial In/Out)

This User Guide only deals with bidirectional call set up.

Full details of configuration for each mode are available

in the LINKSTREAM Range Reference Manual.

An optional ISDN2e Terminal Adaptor (TA) can be installed

in LINKSTREAM. This can be used to replace one or both

of the WAN links with an ISDN interface running at 64Kbps

on each link.

We recommend that you configure your LINKSTREAM

before connecting the TA or serial link cable. The ISDN

cable is supplied with the TA. A second serial link cable

can be ordered separately for connection to a NTU.

We recommend that you configure your LINKSTREAM

before connecting the Ethernet port.

Care should be taken when connecting the Ethernet port

of the LINKSTREAM to your network. Ensure that you

follow the usual precautions as laid down in the Ethernet

guidelines. If unsure of connection procedures for

Ethernet then contact your supplier for advice.

10Base5, 10Base2 and 10BaseT interfaces are provided

on the stand alone LINKSTREAM although only one may

be used at any time. Failure to observe this will corrupt

the data and prevent correct operation. Selection of the

interface is by use of the 6-way multi-coder between

column pairs as set out below:

10BaseT RJ45 Link columns A-B (factory default).

10Base2 BNC Link columns B-C
