Arcadiz introduces spearheading technology for mobile operators on European Market facilitating the migration of 2G to 3G networks
DNX-1u
The DNX-1u BSAG is designed for service in wireless base stations, optimizing the backhaul by aggregating the various equipment traffic and management information, with the ability to withstand the environmentally harsh conditions and extended temperature ranges that are frequently found in these situations. Just as important, the DNX-1u is positioned to help the wireless service provider making a transition from TDM-based 1G and 2G radio service to protocol-based 3G service and beyond.
The DNX-1u:
- Consolidates a multitude of analog and digital services, sharing a common transmission facility.
- Reduces physical footprint in the facility by integrating the functionality from many discrete network elements into a one rack-unit platform.
- Reduces monthly operating expenses. By combining multiple management channels into a single management timeslot, and by cross-connecting the data-carrying TDM timeslots the DNX-1u is able to reduce or eliminate unused bandwidth on the network connections, thereby reducing a portion of recurring costs for T1/E1 connectivity.
- Reduces operating costs to the base stations. The DNX-1u enables to manage virtually every remote device in the BSC from a central location, alleviating the need to have technical personnel on-site, yet properly equipping them if dispatching is required. An IP channel creates the visibility of the remote devices with IP connectivity, terminal server functionality, contact closure inputs (air conditioning, access doors...) and outputs (reset equipment) and differential inputs (temperature and voltage threshold alarming).
- Available at a price that makes the solution viable for both short-term and long-term plans.
DNX-1u provides an economical way for the wireless providers to reduce the number of unused (read: wasted) timeslots by cross-connecting the timeslots and reducing the number of T1/E1 backhaul spans.
Wasted bandwidth typically occurs in two ways. The first is in the form of TDM timeslots that are simply not populated. In most cases, the traffic from these lightly loaded circuits can be groomed onto ½ to ¾ of the previous. The second way that bandwidth is wasted in a cell site is through duplicate and under-utilized network management interfaces. Because there are several generations of cell equipment, many varieties of management mechanisms are used in the cell site. These range from craft terminal interfaces to IP addressable interfaces accessible through physical Ethernet connection. In addition, the base station has ancillary support equipment for monitoring the environment within the site, providing status information via contact closure outputs and measurement devices.
The DNX-1u integrates many of the management functions, reducing the equipment requirements and simplifying the solution. The DNX-1u can provide network integration of physical environment alarms as well as device alarms, and provide a unified contact point for both LAN-based management and craft port managed devices. Most importantly, the integrated management data can be combined into the unused timeslots of the backhaul circuits, reducing recurring costs by eliminating the need for a dedicated network management circuit.
Unlike many solutions in the cell sites, the DNX-1u uses standard IP routing to seamlessly integrate the network management traffic into the larger Operational Support Systems network.
By using the DNX-1u, mobile operators can minimize the need for the field technicians to physically travel to cellular base stations to correct a problem by remotely accessing the system elements at the cell station and speeding the problem resolution time. This represents “hard savings”.
Most cellular base station sites have supplemental sensors for measuring the environmental conditions within the cell site. Among the conditions that they monitor are:
- temperature inside the room/building
- one or more temperature monitors inside the equipment
- humidity inside the room/building
- DC power stability
- AC power supply feed stability
- “door open” conditions (intrusion alarms)
- fire/smoke detection
- flood detection
The provider will often have a dedicated piece of equipment in the cell site, called an Alarm Contact Unit (ACU), which tracks the thresholds of all these conditions and sends an alarm to the Network Operations Center. The best (and most expensive) of the ACU systems will integrate with an IP network via SNMP, with multiple threshold points that are software configurable, and will have integrated WAN connectivity. The DNX-1u provides the same functionality, with better integration into the overall management scheme for the site, and can provide all this functionality at a lower cost than through an external device.
The DNX-1u combines the functionality of six discrete devices (Ethernet Hub, Terminal Server, ACU, CSU/DSU, Digital Cross-connect and Router) into a platform that is space and cost efficient. That all of this functionality is managed through a single, easy-to-integrate interface makes the DNX-1u a unique solution for wireless service providers.
