IPGate AC - Cornet Switching Systems

Expediting migration of critical legacy
applications to modern defence IP networks
Government agencies are starting to take advantage of modern IP networks; however,
a number of proprietary circuit-based applications still exist. The IP-Gate allows
government agencies to maintain their investment in legacy systems while preparing
to take advantage of IP-based services. Being fully JITC certified, applications include
TDM over IP, T1/E1 over IP, Radio over IP, PBX over IP and IP Gateway.
Legacy and Media Conversion over IP Transport
Like other IPGate family members, the IPGate
AC offers advanced features that reliably
transport legacy Time Division Multiplexing
(TDM) and other circuit-based applications
across converged IP networks. Using circuit
emulation services over packet (CESoP)
standards, the IPGate AC supports a wide
variety of legacy analog and digital interfaces
at configurable data rates ranging from 50
bps to 16.384 Mbps. It lets customers easily
and reliably take advantage of converged IP
networks to connect legacy circuits.

Virtual Matrix
The IPGate AC provides far more inter-connect possibilities than
traditional “tunnelling” units which are basically an IP pipeline
connection between two devices. The distributed architecture in
the IPGate AC unit allows any-to-any connectivity between ports
and devices enabling a user to create a “Virtual Matrix”.
User Interface Monitoring
The IPGate AC’s optional bus interface cards let operators attach
their test and monitoring equipment to the unit’s backplane DB-25
female connectors. Port data is collected and presented in real
time for monitoring without data disruption.
Broadcast Mode
The IPGate AC broadcast mode option establishes point-tomultipoint communications for each port.
IntelView, a web-based graphical user interface, is utilized for
system management.
The system maintains the configuration of each port to protect
against the possibility of a power failure. When power is restored,
the system automatically restores user ports to their last
configuration; restoring circuits without any operator intervention.
IP Service Terminations
The IPGate AC supports the following protocols: IPv4 and IPv6,
TDMoIP, Unstructured, Structured, and Structured with CAS.
It is also compliant with G.823, G.824 and G.826/Y.1361 Timing,
Synchronisation, Jitter, and Wander requirements of ITU-T.
Legacy Interfaces
User Port cards are hot swappable for ease of maintenance and
can be interchanged within the same IPGate chassis. Interface
adapters convert standard DB-25 connectors to the physical
connector required for each interface type.
All IPGate AC user interface cards have built in LEDs for
monitoring processor, network A or B, and network A/B link status.
In addition, there are 8 LEDs whose functions vary by interface.

Power Supply Redundancy
The IPGate AC comes with dual redundant power supply modules
that are part of the chassis configuration. The modules are
configured to share the total load but are capable of powering
the entire unit. If a power module fails, the redundant module will
automatically assume the entire load ensuring that the port-to-IP
connections continue to pass data without interruption. A failure
status will be displayed and reported to IntelView.
Packet Redundancy: Each IPGate AC port card offers dual packet
redundancy. The packet is split into a primary and secondary packet
with unique headers and sent to the IPGate AC network controller.
Through the controller’s network connection the redundant packets
can then be routed over two distinct network paths.
A full redundancy option is also offered. In this option the dual
packets are duplicated. Each duplicate pair goes through a different
IPGate AC network controller (two are offered) through a separate
network connection and can then be routed over two distinct
network paths. This option offers optimum packet redundancy.
Ethernet and Packet Redundancy
The IP Gate AC supports both packet redundancy and full network
redundancy via GigE network controllers with automatic failover.

TDM over IP
Media Conversion

requiring changes to the TDM equipment. Leverages continued use
and investment protection of TDM equipment.

PBX Interconnect over IP
Digital and Analog radio systems widely used in Government and Defence
can natively connect over a shared IP infrastructure, or use the Internet
as a back up for Adaptive Time Domain Processing (ATDP) and buffer
management are critical requirements for this application.
Provides T1 or E1 frame-agnostic trunks for PBX interconnection
across the IP network. Eliminates the need for costly leased lines
between locations.
