SIEMENS HiPATH DX
The HiPath DX communications server is an IP communications platform incorporating switching functions, a rich feature set and offering open interfaces and gateways delivering the benefits of network convergence and collaborative applications.
HiPath DX brings the DX family into the HiPath family, allowing it to access a range of new work-points, common connectivity between other HiPath platforms and common applications. HiPath DX provides:
- adoption of IP capability through the HG3500-DX family of integrated Gateways
- reduced costs and improved efficiency through the convergence of existing voice and data networks
- a smooth migration path to convergence, whilst maintaining existing investment in traditional telephony hardware increased application capability and mobility to mirror business changes
- leveraging the benefits of an IP infrastructure without sacrificing feature richness, availability, and reliability
The HiPath DX is able to work seamlessly across circuit switch or data network infrastructures, integrates with other products in the HiPath architecture and supports a wide variety of fixed (analogue, digital and IP) and mobile work-points.
The HiPath DX is available in two variants, the HiPath DX and the HiPath DXR. Both platforms provide customers with a modular, flexible system. The HiPath DX open architecture ensures that systems can be upgraded and reconfigured, with minimal disruption to the customer. Both platforms offer patch panel connectivity for ease of moves and changes, whilst the HiPath DXR is exclusively available in data industry standard 19 inch rack mounting.
DX Voice Server Interconnectivity
DX networking capability is ‘best in class’ allowing a high degree of voice functionality inter-operability and usually cost savings as calls between sites are ‘free’. Usually this is done via either direct DPNSS (Private Network) connections between DX’s or using a Virtual Private Network(VPN); each connection has a ‘line rental’ associated with it.
It is becoming increasingly common for the same sites to also have a LAN / WAN (Local / Wide Area Network) which enable the distribution and sharing of data - high bandwidth LES circuits. As data networks are developed, evolved or replaced due consideration is normally given to ‘transporting’ voice over the data infra-structure; this invariably ensures that suitable equipment and software is purchased to support the requirements of voice.
Capitalising on the above, IP trunking enables the voice traffic (currently using the DPNSS or VPN links) to be transported over the data network without any significant loss of features.
There are potential savings to be made in terms of no voice network line rentals although this does depend on having a suitable data network capable of supporting the necessary Quality of Service (QoS).
Reasons to Upgrade or Invest in DX
- to reduce or eliminate the cost(s) of existing fixed or VPN ‘voice’ links between DX’s (i.e. megastreams)
- to use the available bandwidth within the IP network
- to connect new or existing but unconnected sites using DX to provide the benefits of integrated telephony
- to enable integration with 3rd Parties within a VPN using the data connections
- the DX can operate with both IP and standard voice connections thus the amount and type of traffic which is directed via specific links (either IP or standard voice) can be controlled. This enables the customer to:
- trial IP trunking (to ensure a suitable quality of service is achievable, test the IP network and associated implications of putting voice on the data network)
- use IP trunking as an overflow route at peak times (or as a fall back). This may negate the need for an additional number of standard voice channel links purely to support this requirement.
