Unitel Products - Ericsson Communication Systems
 

Key benefits
o High reliability and low cost of ownership
o Fast network roll-out, easy-to-install and configure
o Efficient usage of spectrum


System overview
The system comprises an indoor unit (IDU) and an outdoor unit (ODU). The units are connected by a single coaxial cable carrying traffic and DC supply. The IDU holds traffic, modem, service and switching functions while the ODU, which comprises a radio unit and antenna, transmits and receives radio signals.

A wide range of antennas allows optimal efficiency for each link, combining high performance with minimum outdoor visibility. Terminals can be configured as unprotected (1+0) or protected (1+1), employing space and frequency diversity. The integrated power splitter for protected configurations makes it possible to install two radio units directly to one antenna, without using separate wave guides.

Ericsson can provide one common radio unit for the complete MINI-LINK point-to-point portfolio that supports all capacity and modulation needs.

High spectrum utilization
For optimal utilization of available resources, MINI-LINK E radio terminals are available with two different modulation schemes, C-QPSK and 16 QAM. This flexibility makes it possible to use spectrum and power efficiently throughout the network.

All outdoor solutions
The Ericsson all outdoor solutions are compact, easy-to-install and have low visual impact. Unlike traditional all-outdoor solutions, they use the same radio and modem units as other MINI-LINK E products. The extensive range of frequencies and capacities and the efficient logistics become attractive from an operators perspective. MINI-LINK E All outdoor solutions are available for end sites as well as hub site configurations.

Data communication networks (DCN)
The use of IP as a standardized, scalable and easy-to-use protocol has set a new standard for how data communication networks should be built to allow low operational costs today and in the future. All MINI-LINK products provide IP DCN functionality, also MINI-LINK E. The Service Access Unit IP (SAU IP) unit fits in an existing indoor magazine and enables legacy networks to be upgraded to modern IP infrastructure.

Network management
MINI-LINK Manager is a powerful network element manager for centralized operation and maintenance of all microwave radio equipment supplied by Ericsson. It can be used as a stand-alone system, or integrated in a higher level network management environment using standard protocols.
 

MiniLink Traffic Node
 
MINI-LINK TN provides a platform for flexible, scalable and cost-effective wireless transmission. With microwave nodes optimized for networks, it targets transmission networks for 2G and 3G as well as fixed and broadband applications. MINI-LINK TN offers advantages on all sites with features that allow a flexible network design, fast implementation and carrier class networks.

The system provides scalable nodes with integrated traffic routing, PDH and SDH multiplexing and protection mechanisms on both node and network level. Configurations ranges from small edge nodes with one single radio terminal to large aggregation nodes where all the traffic from a number of southbound links are aggregated into one link, microwave, cupper or optical, in the northbound direction.

The software configurable traffic routing minimizes the use of cables, improves network quality and facilitates control from a remote location. MINI-LINK TN also offers a TCP/IP and SNMP based management concept. The use of open interfaces ensures inter-operability between different parts and services in the network.

Ericsson can provide one common radio unit for the complete MINI-LINK point-to-point portfolio that supports all capacity and modulation needs. To increase the flexibility, MINI-LINK TN supports a variety of optional features, enabled by Soft Keys. For an installed node, new features or functions can be added by software, locally or remote, without any hardware change. This will reduce cost and supports a true "invest-as-you grow" strategy.

Key features
o Nodes designed for networks
o Any frequency, capacity and modulation
o Flexible Ethernet transport
o Soft Keys to increase flexibility
o Advanced traffic handling and protection
o Efficient management systems

Nodes designed for networks
MINI-LINK TN provides an end-to-end range of nodes that are scalable in capacity and size, suitable for all site types - from the edges of the network to large aggregation nodes. With the different magazines, plug-in-units and optional features available, a tailor made solution for each network site can be configured, starting from a single radio link to a fully-fledged radio hub.

An Edge Node, is located at the edge of the transmission network where all incoming traffic is terminated. In MINI-LINK TN, an Edge Node consists of one radio unit and a stand-alone indoor unit (ATU), for un-protected configurations, that includes modem and traffic interfaces. The unit is self-contained, requiring no magazine, and fits directly into a 19" rack. It provides full flexibility in capacity allocation between Ethernet and PDH traffic.

A microwave Aggregation Node main function is to collect traffic from several sites and to aggregate it into a higher capacity transmission link. MINI-LINK TN provides a powerful high-speed bus architecture that allows traffic to be cross-connected between plug-in units. Both package and circuit switched traffic can be aggregated, without any external equipment.

The minimized use of cables and site equipment results in few site visits, fast installation and provisioning, easy capacity expansion and improved network quality. Typically the node concept reduces rack space requirements by up to 70 % and it will at the same time lower CAPEX and OPEX.

Any frequency, capacity and modulation
MINI-LINK TN provides microwave transmission from 2x2 to 64x2 Mbit/s in PDH and 155 Mbit/s in SDH. With High Capacity PDH, a smooth capacity-migration can be performed in existing microwave networks. It operates within the 6 to 38 GHz frequency bands, utilizing C-QPSK, 16, 64 and 128 QAM modulation schemes.

The advanced microwave technology deployed in MINI-LINK TN includes capacity and modulation agile radio terminals. It means that capacity and modulation scheme can be changed via software by using Soft Keys, with no hardware changes. This flexibility together with the powerful bus architecture and traffic routing of MINI-LINK TN makes it easy to re-configure networks from a remote location.

Flexible Ethernet transport
All type of nodes in MINI-LINK TN handles Ethernet traffic. The possibility to mix Ethernet and PDH traffic reduces the need of cabling as well as external equipment, and it results in a very compact building practice. The total amount of capacity in a node is software configurable, and can easily be allocated and changed in small steps, between PDH and Ethernet.

Soft Keys to increase flexibility
The traffic in the transmission networks will change in the future, both in capacity and type of traffic. To be prepared for these changes, MINI-LINK TN supports several optional features, enabled by Soft Keys. For an installed node, new features or functions can be added by software, locally or remote, without any hardware change. For example: higher capacity, higher modulation schemes can very quickly and easily be introduced when and where it is needed, supporting a true "invest-as-you-grow" strategy.

Advanced traffic handling and protection
MINI-LINK TN supports reliable ring and mesh structures with capacities up to 155 Mbit/s. The network protection mechanism works on E1 level and is media independent, meaning that a combination of microwave, fibre and cupper can be used.

The traffic handling function in the nodes have no single point of failure. The separation of traffic and control makes the system very robust and enables, for example, hot-swap of plug-in boards.

In each node the software configurable traffic routing function can cross-connect the traffic on an E1 level. This can be done on site or from a remote location.

In MINI-LINK TN, ATM aggregation functionality can easily be added. With the introduction of
HSDPA in the mobile networks, ATM aggregation can be used when the data services increase, in order to better utilize transmission resources.

Efficient management systems
MINI-LINK ServiceOn Microwave is a powerful network element manager for centralized operation and maintenance of all microwave radio equipment supplied by Ericsson. It can be used as a standalone system, or integrated in a higher level network management environment using standard protocols. The network control and flexibility provided by the MINI-LINK ServiceOn Microwave translate into low operating costs, quick return on investment and a long-term contribution to profitability.

MINI-LINK TN has an integrated IP router in each node for handling of the DCN traffic. The IP DCN can also be used as transport channel for other equipment O&M data. A number of different alternatives to connect and transport DCN traffic are supported.

Circuits can be routed end-to end through a MINI-LINK TN network. This fully utilizes the remote traffic routing capability of MINI-LINK TN. Continuous re-configurations and upgrades to the transmission networks are a big part of operating costs, making the cost savings from an end-to-end management system significant.
 

Marconi Long Haul

The Marconi LH (Long Haul) microwave system offers rapid roll-out of high transmission capacity with SDH compatibility and integrated network management. Based on long experience in Trunk Radio, this modern long-haul radio system is a more cost efficient solution than fibre in many applications such as fast modification of network topologies, and the rapid roll-out of backbone and feeder networks.



High integration, lowest cost of ownership
Marconi LH can also be used as a redundancy to fibre or when long hop-lengths are needed under difficult conditions. The modern, scalable and highly integrated design provides lowest cost of ownership in all parts of the products life cycle: deployment, expansion and operation

Key features/benefits
• STM-1 transmission, upgradeable to transparent STM-4
• Rapid roll-out
• Frequencies from 3.6 to 13 GHz
• Optimum spectrum efficiency through 64 MLQAM, 128 MLQAM and XPIC (Cross Polarization Interference Canceller)
• Full software downloads capability
• Outstanding compact building practice and low power consumption
• Highly robust system architecture providing high MTBF (Mean Time Between Failure)
• Multiple protection schemes
• The modern design provides lowest cost of ownership
• Plug and Play for Spare Part Handling

Greater frequency band utilization
Up to ten RF channels can be used, depending on the frequency pattern. Using XPIC, each RF channel can be used on two polarizations, thus doubling the transmission capacity. This means that up to twenty STM-1 or five STM-4 signals can be transmitted via a single antenna.

XPIC equalizes cross-polar channels so that the required transmission quality is achieved. The system is operated with 64 MLQAM or 128 MLQAM, depending on channel spacing.

ATPC (Automatic Transmit Power Control) and RTPC (Remote Transmit Power Control) allow repeated reuse of the same frequencies in different directions, in the network node. It also reduces the effects of co-channel and adjacent channel interference in networks with high traffic density. When possible, the transmit power is reduced by up to 20dB below its maximum value. The highly flexible, software-controlled ATPC and RTPC allow the correction of up- and down-fading and can easily be adapted to local conditions. Marconi LH is designed to make optimum use of available frequency bands, with co-channel operation using dual polarization.

Increased quality through radio protection switching
The system uses protection switching functions, such as frequency diversity or hot standby, to increase the availability and quality of the transmission links. These functions are independent of SDH network protection switching, and are implemented as Regenerator Section Protection, without affecting any existing Multiplex Section Protection or Ring Protection. The control channels required for microwave radio protection switching are transported in the Regenerator Section Overhead.

The n+1 protection switching option can be expanded step-by-step up to a 2x(9+1) configuration. Subsequent extensions can be implemented without interruption. Optionally, the protection channels can be released for the transmission of lower-priority data.

Space or angle diversity can be used to guarantee the required transmission quality even with radio hop lengths of more than 30 to 40 km, or where propagation conditions are difficult.

Compact 10-in-one system architecture
The system components are all housed indoors in ETSI cabinets. Up to 10 STM-1 channels, including the protection switching function as well as redundant power feed, can be accommodated in a single rack. The system design is highly modular, simplifying installation, expansion and operation.

Each system consists of three sub-functions:
• RF branching
• Transceiver unit (TRX)
• Baseband unit (BBU)
Only the RF branching and the Transceiver unit are frequency-dependent.

RF branching
Channel filters connecting the transceiver units to the antenna system permit low-attenuation connection of all RF channels of one polarization to one antenna. Diplex filters are available for larger structures, minimizing the attenuation of the channel filter chain.

Transceiver unit (TRX)
The transceiver units have broadband capacity for a complete frequency band, with the corresponding RF channels being defined by a synthesized oscillator. The associated settings in the transceiver are affected electronically and independently, enabling an on-site channel changeover.

Baseband unit
The baseband unit performs all SDH processing and radio protection switching functions. It also provides optical or electrical baseband interfaces, as well as the interface for up to five transceiver units (STM-1 signals).

Optionally a 1+1 Multiplex Section Protection together with a full equipment protection are provided for the baseband interfaces.

Ethernet/TDM solution
Ethernet interfaces (10/100/1000BASE-T) and TDM interfaces (E1) are provided by combining the radio system with the powerful Ericsson multi-service portfolio.

Verified scalable solutions using Marconi LH in combination with an OMS multiplexer are available – OMS 8xx for low capacities; OMS 12xx or OMS 16xx for higher capacities.

All OMS multiplexers perform a highly efficient cross-connection of Ethernet and/or TDM traffic. The OMS multiplexers and the Marconi LH radio system are supported by the same network management system providing an integrated, easy and effective control.

Protected STM-4 transmission
The DPU STM-4 system component, which is connected upstream of the STM-1 microwave radio units, permits the transport of a STM-4 data stream consisting of a concatenated VC-4c via a Regenerator Section in the SDH network. This application meets all the criteria for use within STM-4 trunk and ring networks. All logic and operational functions are implemented in a single integrated chip.

Optimum antenna systems
Ericsson develops and manufactures its own complete modular antenna range for a wide variety of applications. The range offers optimum dimensioning and design of the microwave transmission path.

The convenience of local monitoring
A monitoring circuit is integrated in each module to check the condition of the transmission link. All alarms, configuration data, measured values and performance data can then be retrieved locally, either via an F interface or centrally via the management interface. Each module can be addressed and controlled separately. The operator PC uses a graphical interface so that several functions can be clearly displayed at the same time. Commissioning and configuration can be carried out electronically, with no need for equipment settings. Software can be downloaded locally or via the management interface.

All the software, together with the configuration for a complete terminal is stored in an on-site memory card, allowing for plug-and-play functionality in case of module replacement.

Managing the system
Simple connections are made via the STM-1 Section Overhead (DCCr or DCCm), the QD2 interface or the LAN interfaces Q3p and SNMP to Ericsson’s integrated network management systems, such as ServiceOn Access; ServiceOn Optical; ServiceOn Microwave or MINI-LINK Manager.

The radio system will automatically search for and establish the shortest path and the necessary redundancy to maintain reliability under fault conditions. The open OSI Q3p protocol stack and the integrated multi-protocol stack (QD2, OSI and TCP/IP) allow adaptation on any SDH multiplexer or integration of any SNMP-managed equipment. This provides the radio with a simple plug-and-play management solution.
