iPASOLINK 400
1. INTRODUCTION
The demands for mobile and fixed broadband services are justifying the technology, topology
and business model innovations being implemented today. Moving into unified IP packet
networks and end-to-end network management allow you to offer premium services including
conventional voice service over packet as well as sharing or reselling your backhaul
bandwidth. However, the right backhaul evolution strategy very much depends on the differing
motivations of each operator such as preferences in OPEX, CAPEX, flexibility, control and
scale.
iPASOLINK is NEC’s most advanced and comprehensive optical and radio converged
transport product family, providing solution for backhaul optimisation and transformation to
help you achieve your business objectives such as cost efficient integration of both TDM and
carrier-class Ethernet network and versatile and smooth migration from TDM to IP next
generation network. The iPASOLINK family covers from the last mile to the aggregation metro
backhaul and is composed of iPASOLINK 200, 400 and 1000 series.
iPASOLINK 400 is for medium nodal application, such as three (3) southbound links are cross
connected or aggregated into one northbound link or vice versa, ring node and large capacity
D/I repeater applications etc., providing versatile routing of flexible combinatorial native TDM
and native Ethernet traffics, as well as link and each transport level independent ring
protections. As the same as iPASOLINK 200, iPASOLINK 400 provides up to 440 Mbps
transmission capacity per link and advanced adaptive modulation scheme operating in 6, 7, 8,
10, 11, 13, 15, 18, 23, 26, 28, 32 or 38 GHz bands.
The iPASOLINK 400 consists of antennas, outdoor units (ODU) and 19 inch one (1) U indoor
unit (IDU) and accedes to very high performance in very compact units and ultra high
reliability gained through NEC’s rigid TQC activities and vast experience in wired and wireless
communication fields.
Figure 1
iPASOLINK 400
The traffic interface of iPASOLINK 400 is a basic D/I interface module and four (4) front
access universal card slots which are connected to TDM cross connect and L2 switches with
interface buses. These card slots are provided for radio interface (modem) and additional
interface to satisfy various D/I or interface and topology requirements. Versatility of the
iPASOLINK 400 is thus obtained. As the basic D/I interface configuration, iPASOLINK 400
can be configured up to four 1+0, two 1+1 twin path, hot standby, diversity radio links or,
thanks to NEC’s most advanced cross polarization interference canceling techniques, double
the transmission capacity up to 880 Mbps utilizing both polarizations within the same costly
and limited licensed radio frequency channel. All this is achieved without any header
suppression or compression of packet data.

2. ADVANTAGES
The iPASOLINK family is designed around two (2) basic principles to provide the all-IP wired
and wireless intelligent converged network for customer’s benefits.
Providing more transport flexibility & reliability:
iPASOLINK family includes microwave and fiber transmission, switching and aggregation
functions, is supporting from E1/T1 to STM-16 or carrier-class FastEthernet to 10G Ethernet
for transmission of TDM and packet data, and designed to deliver high throughput and low
latencies – while avoiding reliability problems of TDM-over-packet network, QoS, route
protection on different TDM and Ethernet backhaul topologies. Technologies such as double
capacity radio through XPIC with hitless adaptive modulation, independent cross-connection
and MPLS switching capability bring performance, power and flexibility to the hybrid network
toward next generation IP/mobile networks.
Operation continuity & upgradability
Based on NEC’s commitments of IP migration strategy, enhancement of end-to-end TDM and
packet backhaul management and northbound interface capabilities - for network optimization,
traffic engineering, QoS and route protection management - are included into iPASOLINK
portfolio. Together with these enhancement, "Pay as you need" remote upgrade concept is
also applied to iPASOLINK family platforms. The modular construction with universal card
slots and integrated management software ensures operation continuity and upgradability
from each hop or node.
Customer Benefit
NEC’s backhaul engineering foresights enable the adoption of IP network in cost-effective
manner. The iPASOLINK broad scope of backhaul media and convergence technologies
such as MPLS allow any service (fixed, mobile or wireless broadband) to happily co-exist in
one physical backhaul. This backhaul unification by iPASOLINK platforms reduces cost and
complexity where operators require multi-service backhauls or complete service transparency
enabling to offer backhaul capacity to other providers to earn further revenue from your
backhaul. Moreover, you can re-design your backhaul in terms of topology, capacity and
intelligence while reusing existing infrastructure. Specifically, in the mobile backhaul, the
iPASOLINK family ensures you can scale from 2G/3G to higher broadband access speeds
without a proportional increase in cost.
Advantages of iPASOLINK 400
The iPASOLINK 400 has all of above advantages included as a part of up to 4 links node
platform. These are briefly listed as follows;
- Native TDM and packet transmission enabling to migrate into carrier-grade full packet
radio with scalable throughput capability.
- Front access universal card slots configuration enabling to meet full range of your
transmission interface and interface changeover needs.
- Easy addition of functionality with "pay-as-you-need" upgrade concept on the same
hardware. As an example, you can double the transmission capacity up to 880 Mbps
over a single radio frequency utilizing both polarizations without any requirement of
neither additional outdoor foot prints nor indoor mounting spaces.
- Full range of synchronization (TDM, Sync Ethernet, IEEE1588)
- Multi-service support with PWE and aggregation
- Independently support TDM and Ethernet ring protection

- Field-tunable based on your radio frequency channel* license through Local Craft
Terminal (LCT).
*Note: Limited within the specified sub-band. Alteration of sub-band can be easily achieved by

3.4.4. Adaptive Modulation Radio (AMR)
AMR is a technology to improve robustness mainly in the packet transmission environment by
utilizing thermal threshold difference between modulation hierarchy, such as QPSK 256 QAM
etc. For instance, intensive rain causing receiving level attenuation at high frequency bands,
AMR keeps the link availability by automatically and error-free selection of the lower thermal
threshold modulation. For example, QPSK threshold is 6 dB lower than 16 QAM but
transmission capacity becomes half (See Figure 2).
In the IP packet transmission, i.e., no hierarchy transmission case, link connectivity in other
word, robustness might be more important factor even though transmission capacity is
significantly reduced. However, in the hybrid transmission, it is recommended to keep the
same transmission capacity for TDM transmissions including PWE or CESoP even at
degraded receiving conditions. Prioritization between TDM and Ethernet packets or
prioritization between Ethernet ports or VPN-base is the quite important matter to maintain the
quality of the highest priority service.
Since severe rain attenuation is rapidly fluctuated, it is required to sufficiently correspond to
such high descent and ascent speeds of receiving signal level. Adoption of small stepping
method such as utilizing both forward error correction code ratio difference and modulation
may not always catch up to these speeds and may not effectively work in real world.
Based on NEC's vast experience on microwave to millimeter wave propagation, the most
realistic reliable AMR functionality from the device level was developed and equipped in
iPASOLINK family platforms retaining the QoS parameter setting capability on AMR
operation.

4. APPLICATIONS
The MW radio products belonging to the iPASOLINK family are modular backhaul platforms
that integrate a comprehensive set of packet switching, TDM cross-connect switching and
microwave/optical features covering all applications - from the tail to the metro backhaul
through aggregation node.
4.1. Applications for Mobile backhaul
Traffic of mobile circuit switched services (CS) is maturing and CS Voice ARPU is
approaching the saturating point. In contrast, Packet data traffic is gradually increasing.
Although current data traffic is not so large due to high cost to the users and limited service
contents, revenue increase can be expected by expanding the IP services especially for
corporate sector services (M2M, B2B/C) such as VPN and cloud computing services to
sensors, smart phones and thin-client terminals. However;
- Amount of required bits for data service is much larger than those for voice and
significant bit-cost reduction is absolutely required.
- Transmission capacity per cell will increase significantly. This has to be improved while
considering that the available existing spectrum is limited and new spectrum would be
higher in frequency and cost.
The following might be a mandatory requirement to survive this highly competitive field:
- Spectrum efficiency improvement including adoption of multiple Mini/Micro/Fem to cells
in mobile RAN and;
- Adoption of low-cost packet data aggregation (statistical multiplex) and autonomous
decentralization such as off loading, metro mesh WDM and MPLS VPN etc in Ethernet
backhaul.
With all these considered, it is clear that migration to all-packet mobile networks is the way
forward. However, current majority earnings are from 2G/3G CS voice service which can not
be replaced to LTE in a short period of time. All-IP migration strategy of existing 3GPP
Release-99 operators might be different from other mobile operators due to difference of
mobile architectures adopted.
Based on these mobile trends and applied mobile architectures, the iPASOLINK for mobile
backhaul solution is shown in Figure 4.1. The iPASOLINK family supports Dual Native (native
TDM and native Ethernet) operation. It is possible to provide TDM and Ethernet Hybrid

iPASOLINK for Mobile backhaul
The iPASOLINK family supports the all of the following transmission architecture:
- Native TDM
TDM based network is the bandwidth-guaranteed and synchronous network. It is free
from time and synchronization issues. However, TDM network can not manage the
growth of data traffic efficiently.
- Native IP
Unlike Native TDM network, IP based network can accommodate the growth of data
traffic efficiently. In addition, wiring work can be reduced dramatically as a result of
shared connections.
However, IP-based network, due to its asynchronous and on-demand nature, does not
guarantee synchronous delivery of data. Therefore, synchronization issue due to
fluctuation of delay, latency or jitter must be carefully considered in transmission of
mobile service.
- Dual Native (Native TDM and Native IP)
Both packet switching and TDM cross connect are supported natively, which enables
flexible transport per traffic type on a single platform. Without incurring additional
latency, delay/jitter sensitive traffic and clock such as 3GPP Release-99 traffic is
transmitted on TDM network directly, and IP based traffic such as LTE traffic is
transmitted on IP network directly without conversion. Moderate packet data growth may
be efficiently aggregated by statistical multiplexing while keeping the quality of delay/jitter
sensitive TDM services.

- TDM splitting (with PWE) and Traffic Offload/Concentration
TDM splitting enables a port of legacy network traffic, such as HSPA
data, to be dispensed onto IP network with Pseudo-Wire Emulation
(PWE), keeping only critical and timing-sensitive data on TDM network.
With this functionality, it is possible to streamline legacy network while
increasing IP network usage.
PWE should be applied for transmission of jitter and latency relaxed services or where
clock synchronization within mobile RAN has been established by adoption of other
synchronization measures.
Traffic offload allows the operator to unload their IP traffic, including emulated legacy
traffic, onto other cost effective IP network. The benefit of traffic offloading is twofold:
> Differentiation of services to customers
> Reduction of OPEX by converging voice and data traffic
In contrast to offload, concentration creates an opportunity for wholesale operators and
carriers to maximize the utilization of their networks by converging services and traffic
from various customers.
4.1.1. Mobile network (2G/3G/LTE)
Mobile services require very accurate clock, such as 0.05ppm for 3GPP macro base station,
for Location Service (LCS), handover and other pseudo synchronization among mobile
platforms. Usually clock is distributed from BSC/RNC in 3GPP Release-99 GSM/UTRAN
(2G/3G) systems. It is very hard to transmit this very accurate clock to entire BTS/e-NodeB
through ordinary IP network. IP migration process should be carefully considered and planed
to minimize the risk to existing services and additionally required CAPEX and OPEX for
2G/3G services being turned off in future. Therefore, adoption of Dual Native backhaul would
be risk-free, the most flexible and cost effective migration method towards all-IP network.
Nodal application for mobile network
iPASOLINK 400 has Up to 4-way nodal capability. Up to 4 ODU can be connected to one
iPASOLINK 400 IDU. Nodal solution minimizes equipment, and can reduce cabling and
power consumption.

6.2. Features
6.2.1. Any platform
Free from OS limitations, PNMSj runs on either Windows® XP or Windows Vista® or UNIX®.
PNMSj is based on SNMP Manager/Agent Technology.
6.2.2. User-friendly operation
PNMSj displays a network overview with click and pull down menus to obtain detailed status
information and to change the configuration of the network elements.
The multiple level window structure provides easy guidance to pinpoint the PASOLINK station
of concern and subsequently the component of concern.
Starting with a map showing the sub-groups, followed by maps showing the various
sub-group configurations, an operator can find an overview window for any PASOLINK station
quickly.
6.2.3. Link oriented Management and Control
For operational convenience, the PNMSj automatically displays the status of the opposite
PASOLINK station together with key link parameters.
6.2.4. Remote access and control
PNMSj Clients are able to monitor and control NEs using most Web browsers (IE, etc).
Remote NEs can be accessible using either In-band or Out-of-band interface.
6.2.5. Event logging
This PNMSj is useful for monitoring all events occurring within the network. It is designed to
ease the maintenance and troubleshooting work on the PNMSj. The events are listed in an
easy–to-view formats giving the user information about the date and time it occurred, the
network element where it occurred, its item and status. The User column has offered for event
log that the user controlled, and showing login user name is also supported.
The event log window is incorporated in the PNMSj main window. The logs are displayed at
the bottom of the PNMSj screen.
6.2.6. Alarm Management
The Active Alarm function supports monitoring of active alarms on all connected network
elements. Alarms that have been cleared in the NE will remove on the Active Alarm window
and logged in the Alarm History window.
The Alarm Information View is used to view the summary of current active alarms. This screen
shows the list of active alarm information of NEs belonging to the same group. The list also
shows what alarm severities are currently active in the NE and whether it has been
acknowledged or not.
The total count of current active alarms (Not Ack / Total) in each category is shown at the top
of the main window.

6.2.7. ITU-T G.826 performance monitor
The PNMSj is able to retrieve the performance data of all listed PASOLINK stations and their
associated microwave link in accordance with ITU-T specification G.826.
- Scheduled or on-demand upload.
- Report or chart presentation.
- Threshold setting and alerts.
6.2.8. Security
Users are registered by means of a login name and password.
To protect the network and network management system from unauthorized access or
unauthorized modifications, the privileges are assigned to the groups rather than to the
individual user. A user will have the privilege provided to the group where it belongs.
Moreover, the control of network elements can be customized and provided only to specific
groups. This allows the administrator a high-flexibility of assigning not only the PNMSj
functions but also the control and management of individual NE.
Lastly, users and groups created in PNMSj are internal to PNMSj only and do not correspond
to Windows users and groups.
6.2.9. SNMP interface
PNMSj provides an SNMP interface to make the PASOLINK equipment an integral part of a
higher level of network management system.

10. ANTENNA AND ACCESSORIES
10.1. Antenna configuration
Two (2) antenna configurations are available for protection type: (1) One-antenna system
using hybrid (HYB) RF combiner and divider, and (2) two-antenna system using 2 separate
antennas for two ODUs. The hybrid is the passive device that combines and divides the
signals between two ODUs and antenna. Note that one-antenna system requires only single
antenna, however, additional loss between ODUs and the antenna have to be considered. On
the other hand, two-antenna has high system gain in the same non-protection type
configuration.
The complete menu of PASOLINK antennas includes antennas with diameters of 0.3m up to
1.8m. They are designed to meet stringent requirements on mechanical rigidity. All
PASOLINK antennas with diameters of 0.3m to 1.8m can be directly mounted to the ODU in
case of 1+0 configuration. This has relevant cost and reliability merits and makes the
installation quicker and easier. The PASOLINK pole mounting structure is designed in a way
that the ODU can be replaced while keeping the antenna and mounting bracket, including
orienteering, in place. The reflectors of the antennas are covered with white diffusive paint
and the mounting structure is hot-dip galvanized.

10.2. Hybrid Combiner/Divider
NEC has developed Hybrid Combiner/Divider over the full range of microwave frequencies for
PASOLINK Series digital microwave radio point-to-point fixed wireless systems. This Hybrid
Combiner/Divider comprises directional coupler, antenna interface, radio mounting interfaces
and polarizer. The RF signal power
ower received by the single polarized antenna is equally
distributed and sent to two outdoor units through the Hybrid Combiner/Divider for 1+1
protected systems.
There are two types of NEC Hybrid Combiner/Divider, one is coaxial cable connection type for
6/7/8 GHz Bands and the other is WG connection type for 10 - 38 GHz Bands. NEC Hybrid
Combiner/Divider is suited for Andrew or RFS Antenna, and all NEC ODUs.

10.3. 10 dB Coupler
NEC has developed 10 dB Coupler over the full range of microwave frequencies for
iPASOLINK Series digital microwave radio point-to-point fixed wireless systems. This 10 dB
Coupler comprises directional coupler, antenna interface, radio mounting interfaces and
polarizer. The RF signal power received by the single polarized antenna is unequally
distributed to two outdoor units in the ratio of 9 to 1 through the 10 dB Coupler for 1+1
protected systems. Using this 10 dB Coupler, regular side signal level could be kept higher
than in using 3 dB equal Combiner/Divider.
There are two types of NEC 10 dB Coupler; one is coaxial cable connection type for 6/7/8
GHz bands and the other is WG connection type for 10 - 38 GHz Bands. NEC 10 dB Coupler
is suited for Andrew or RFS Antenna, and all NEC ODUs.

10.4. OMT (Ortho-Mode Transducer)
NEC has developed Ortho-Mode Transducer (OMT) over the full range of microwave
frequencies for Waveguide (WG) interface of PASOLINK Series digital microwave radio
point-to-point fixed wireless systems. The OMT comprises Ortho-Mode transducer, antenna
interface and radio mounting interfaces. The two independent RF signals received by dual
polarized antenna are separated and sent to two outdoor units (ODUs) through the OMT for
2+0 systems.
OMT enables dual polarization feature to double the transmission capacity for the PASOLINK
system. NEC OMT has WG connection type for 11-38 GHz Bands, which is suited for RFS
Antenna and all NEC ODUs.
