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.

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,
