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.

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 rear panel of the unit provides for all connections to

Configured automatically or manually, one or both of the
WAN links can be replaced with an ISDN interface running
at 64Kbps on each link. The module is plugged into rear
socket on the LINKSTREAM.

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 :
LINKSTREAM Terminal
RJ45 DB25 Function
1 <<-- 4 RTS
2 <<-- 20 DTR
3 <<-- 2 TXD
4 -->> 8 DCD
5 -->> 3 RXD
6 7 GND
7 -->> 6 DSR
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
