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,
