Management
InterChange iQ 2000 products are designed for years of error-free running with little, or no,
requirement for management involvement once initial set-up is complete. Normally
any network faults are notified and diagnosed from alarms provided by the attached
equipment, after interaction with the InterChange unit, and it is superfluous and confusing to
network operations staff to have these indications repeated at a second interface.
For the rare cases where installation philosophy requires direct notification of alarms,
InterChange iQ 2000 and iQ 2000plus have four types of management interface:
• LEDs,
• A relay which can make or break an alarm circuit in the event of a major hardware
related failure,
• An RS-232 serial interface which can be used for fault diagnosis and configuration
management, either from a locally connected PC running Vision iQ, or from a
remote PC via a modem link, and
• Ethernet.
These interfaces operate concurrently and quite independently.

InterChange iQ 2000 and iQ 2000plus
Vision iQ
Vision iQ is a Windows application for managing the InterChange iQ 2000 and iQ 2000plus.
Vision iQ is used to download protocol conversion software to the InterChange unit from a PC,
using the Download utility. The product is configured using the Vision iQ application described in
this manual. Vision iQ also manages the operational, diagnostic and alarm information for each
port used in the conversion or channel grouping.
Vision iQ identifies the software and hardware facilities available on an InterChange unit and
displays parts or all of the configuration and management dialogues accordingly.

Introduction
1 Introduction
1.1 InterChange iQ 2000
InterChange iQ 2000 is a dual port ISDN unit designed to perform signalling and service
reconciliation between two unlike ISDN signalling systems.
It is typically deployed to attach:
• a QSIG (or DPNSS) PBX to a DPNSS (or QSIG) network, or
• a number of DPNSS PBXs to a QSIG or Q.931 backbone (e.g. VoIP or ATM)
network, or
• a DPNSS PBX to a Q.931-based Public ISDN service (such as ‘ISDN 30e’).
When attaching a QSIG (or DPNSS) PBX to a DPNSS (or QSIG) network,
InterChange iQ 2000 provides seamless service interworking between the attached PBX and
other PBXs in the network, including inter-operation of most of the commonly used services.
InterChange iQ 2000 facilitates basic call interworking, including simple services such as
calling and connected identity when attaching a number of DPNSS PBXs to a QSIG or Q.931
backbone network, or a DPNSS PBX to a Q.931-based Public ISDN service.
In addition, when attaching a number of DPNSS PBXs to a QSIG or Q.931 backbone
network and the core network supports QSIG signalling, InterChange iQ 2000 can transport
DPNSS signalling across the network and deliver it practically transparently via a similar
InterChange unit to a remote DPNSS PBX. In this mode all DPNSS Supplementary Services
are supported apart from some link-specific Traffic Channel maintenance services.
InterChange iQ 2000 supports 2 E1
Primary Rate [2 Mbit/s (30B + D) Common Channel
Signalling] interfaces; providing a single Primary Rate conversion. It
is a portable unit that can
be mounted on a desk. A kit of brackets is also available to allow the unit to be installed on a 19
inch rack. It is particularly suited for use in Customer Premises Environments (CPE) to interface
equipment into Virtual Private Networks.
Figure 1: InterChange iQ 2000 in a Private Network.
4 UM380 03 010
InterChange iQ 2000 and iQ 2000plus
Figure 1 shows DPNSS PBXs interconnected across a QSIG network. In this configuration,
the combination of InterChange units and the network behave as a single DPNSS transit
node and transports DPNSS supplementary signalling.
Figure 2: InterChange iQ 2000 in a CPE.
Figure 2 shows an InterChange iQ 2000 interfacing a PBX using the UK standard DPNSS
protocol to the QSIG/Q.931 protocol.
Conversions operate on the common signalling channel only. Bearer circuits are passed directly
through the unit. Each protocol support is configurable to meet specific application needs.
The Virtual Private Network protocol support can be configured to operate into sub-equipped
ISDN trunks, allowing the user to maximise the benefits of the advantageous Primary Rate
ISDN tariffs now being offered by some PTOs.
1.2 InterChange iQ 2000plus
The IiQ 2000plus is a variation of the InterChange iQ 2000 providing some additional
facilities:
• The ability to perform diversions on behalf of the PBX; and
• Support for the Q.932 ‘redirecting number’ element for diversion;
• Advanced Wizard custom configuration for Cisco Call Manager;
• The ability to display DPNSS Message Waiting Indications on telephones
controlled by Cisco Call Manager.
If a unit is first installed with version R.2.1.0 of the operating software, an IiQ 2000 may be
upgraded to an IiQ 2000plus. For more information on the upgrade, contact your distributor /
reseller or Westell Account Manager.
1.3 Management with Vision iQ
Vision iQ, the Management Interface, provides the facilities to connect (locally or remotely) to an
InterChange iQ 2000 or iQ 2000plus, display diagnostic information and configure the unit.
Vision iQ allows you to:
• connect and disconnect from the management terminal,
• set up a definition for the InterChange iQ 2000 or iQ 2000plus unit,
UM380 03 010 5

UM380 03 010 9
Hardware Installation Procedure
2.3 Power-On and Self-Test
2.3.1 Terminal Connections
To run installation and configuration software, access via a PC with Vision iQ is required. A
terminal can also be used as a monitor while the self-test software is running.
On the rear panel of the unit is a 9-way D type connector marked Management, as shown
in Figure 4. To connect a PC, refer to the cabling and communications specifications in
Appendix C.
1 Make sure that no ISDN cables are connected to the rear of the unit.
2 Make sure electrical power is available and set the unit mains switch (located on
the rear panel at the right of the unit) to ON (I).
3 Check that the Power LED comes on ORANGE. This is the right-hand LED on the
front panel, shown in Figure 3.
2.3.2 Self-Test
When power is first applied, the Power LED on the front panel comes on ORANGE and the
four STATUS LEDs come on and go off in sequence (from left to right) to indicate the unit is
performing the Self-Test. This is a sequence of tests (stored in the Boot Flash) which check
correct operation of the hardware functions. Allow this to run to completion. The Self-Test
should complete in less than one minute.
Successful Self-Test
When all the tests have completed successfully, the Self -Test Module invokes the Loader
module. The Power LED changes colour from ORANGE to GREEN.
Self-Test Failure
If any test in the sequence fails then the cycle of the STATUS LEDs will stop (with one LED
remaining on) and the Power LED will remain ORANGE.
At the end of the test sequence, the self-test software does not pass control on to the
operational software. At a 30 second repeat interval the terminal (if connected) receives
a summary of all errors found during the self-test. The self-test will attempt to re-run
approximately every five minutes. This is done to guard against any transitory problems.
When an error is indicated consult Chapter 7 Problem Determination, for the appropriate
corrective action.
Once errors have been corrected make sure the self-test runs satisfactorily
to completion. Only proceed when self-test passes. InterChange iQ 2000 and iQ 2000plus
are made to reset and re-run its self-test by setting the power switch on the rear of the unit to
OFF (O) then setting it to ON (I).
When self-test has been completed correctly you may proceed to perform configuration and
the operational checks.

2.6 Cabling into a Management System
This section explains how to connect the InterChange iQ 2000 and iQ 2000plus into a
Management System via the alarm relay outputs.
2.6.1 Alarm Signal Cabling
Prepare and route an alarm cable to the left hand side of the cabinet (viewed from the rear)
(refer to Figure 4). Connect the cable to the 3-way Weidmuller ALARM connector at the rear
of the first InterChange iQ 2000 unit. Lock in place.
Connect the cable to an Alarm Panel or alarm signal detector at the remote end.
2.6.2 Alarm Signal Cable Test
Leave the unit powered on with no ISDN cables connected. This causes an alarm condition
which is notified by the alarm detection equipment.
If no alarm condition is notified then correct the cabling.
2.6.3 Management Terminal Cabling
InterChange iQ 2000 units are normally run with an in-situ management terminal. Where it
is required, route the prepared Management Terminal cable to the left hand side of the unit,
connect to the D-9 outlet labelled Management on the rear of the unit (refer to Figure 4), and
lock in place. If the InterChange iQ 2000 or iQ 2000plus is to be managed via the Ethernet,
the user should supply a suitable cable (cat. 5 UTP patch cable) with a RJ45 connector at
the InterChange iQ 2000 unit end for connection to the user Ethernet connection.
Connect the cable to a PC or to a remote PC via a modem or the Ethernet.
2.6.4 Management Terminal Cable Connection Test
Turn on the unit and the remote terminal. Make sure that the terminal communications
parameters are set up correctly, as specified in Appendix C. Let the self-tests complete and
the unit enter operation. From the management terminal, enter any management command
and check that the correct response is returned.
If the correct response is not returned then corre§ct the management cable.
Leave the unit switched on for the next test.

Hardware Installation Procedure
2.7 Network Cabling
This section explains how to connect an InterChange iQ 2000 unit into the ISDN.
Warning:
Before attaching ISDN cables, perform any power-on configuration which may
be required to make the signalling conversion fit the particular application. Failure to
do so may cause unexpected effects on the remote equipment when the InterChange
iQ 2000 unit is connected.
2.7.1 Port Usage
At the rear of the unit are two pairs of BNC connectors (75 Ohm) marked Rx and TX, and
two RJ45 connectors (120 Ohm). There is a switch marked 75 Ohm and 120 Ohm for
changing between the connectors. PORT 1 and PORT 2 are indicated on the rear.
Port 1 presents a Q931 Protocol variant and Port 2 presents DPNSS. The exact parameters
of each protocol are configured through the off-line menus.
The sense of each connection can be changed by configuration.
2.7.2 Cabling Practice
Specimen drawings for BNC and RJ45 plug terminations will be provided on request.
Label all cables, especially 75 Ohm coax pairs, during installation. Labelling greatly eases
any trouble shooting or subsequent reconnection/re-configuration of the units.
Attach the label to each cable in an easy to read location indicating the InterChange
equipment (if there is more than one), the port it connects and its direction. For example:
1/1 TX (Q.931)
1/1 RX (Q.931)
1/2 TX (DPNSS)
1/2 RX DPNSS)
Depending on the installation, labelling may be beneficial at either or both ends of
each cable.
2.7.3 Cabling Procedure
Connect to the appropriate connectors at the rear of the unit.
When connecting cables to a live unit, connect the pair of cables attaching to Customer
Premises Equipment (CPE, e.g. PBX) before connecting to the remote network, particularly if
this is a public service network.
Cable continuity can be checked by applying a physical loop, TX to RX, at the attached
equipment.
16 UM380 03 010
InterChange iQ 2000 and iQ 2000plus
Warning:
When applying loopbacks, assert the public network loop before the private
equipment loop, and remove the loops in reverse order. Failure to observe this
precaution may lead to excessive port error reports and the link being put spuriously
out of service.
Remove the loopbacks (see the notes above on the order of removal) and connect to the
remote equipment.
Network cabling is now complete.

Switches and LEDs
3 Switches and LEDs
This chapter describes:
• Operation of the switches on the rear panel
• The information provided by the LEDs on the unit front panel
During normal operation of the unit the LEDs indicate its operational status. This information
is particularly useful in diagnosing cabling faults and external equipment problems, during
both installation and normal running.
3.1 Switches
3.1.1 Power ON/OFF switch
The power ON/OFF switch is located on the rear panel adjacent to the mains connector. It
switches mains electricity to the Universal Input Power Supply Unit.
3.1.2 Sync switch
The Sync switch allows the unit clock source to be synchronised to either of the primary
ports (P1 or P2). It is located on the rear panel between the Alarm connector and the
Ethernet connector. The selection must be made before power is applied to the unit.
Ideally, the Sync switch should be set to whichever port is connected to the network so that the
unit is synchronised with a central clock source rather than the clock source of another unit.
However, in a Packet Switched Network the synchronisation should come from the PBX.
3.1.3 Port Impedance switches
The Port 1 and Port 2 impedance switches allow the selection of either 75W or 120W
impedance to be made. They are located adjacent to the Port 1 and Port 2 connectors on
the rear panel. The selection should be made before power is applied to the unit.
3.2 Front Panel LEDs
The unit has 10 LEDs on its front panel. During the self test sequence, and in the event of an
alarm, they show unit status information.
3.2.1 Status LEDs
There are 4 red Status LEDs; S3,S2,S1 and S0. They indicate unit status in conjunction with
the two port LEDs, P1 and P2. During unit self-test, the status LEDs will come on and go off
in sequence and in the event of a self-test failure, stop with one LED remaining on.
18 UM380 03 010
InterChange iQ 2000 and iQ 2000plus
3.2.2 LAN LEDs
Three LEDs indicate LAN activity. A red TxD LED comes on when if data is being
transmitted; A red RxD LED comes on if data is being received and a green Link LED comes
on if the connection is OK. If Ethernet is not connected, these LEDs will be off.
Note:
The RxD LED will flash for any data on the Ethernet, regardless of destination.
3.2.3 Port LEDs
There are two red Port LEDs, P1 and P2. Together with the Status LEDs, they indicate unit
status. When the unit is operating correctly, these LEDs ripple, with all status LEDs off.
When a problem exists, the Port LEDs will show its location (P1 or P2, or if both P1 and P2
are lit, a major alarm exists). The status LEDs will then indicate the problem (refer to 7.4.3).
If more than one has a problem, they will be shown in a cycle of five seconds each.
3.2.4 Power LED
The Power LED has two functions. When power is applied, it comes on orange to indicate
the unit is in self-test mode. When the self-test has been satisfactorily completed, it changes
to green to indicate the unit is functioning correctly.
