3. New Features & Capabilities - Introduction

New RF band, 28GHz (For sectors of 45,90 and 180 degrees):

Software version 2.00 supports a new RF band, 28 GHz (Bands C and D),

which complies with the European ETSI and standard for PMP systems.

28GHz is available for 45,90 and 180 degree sectors.

NIU-ATM 2xE3: The NIU-ATM 2xE3 card enables network connectivity

towards the ATM backbone over an E3 physical interface (Two E3 ports per

card).

The NIU-ATM enables the users’ data and leased lines services to be carried

over ATM by AAL5 and AAL1 respectively, towards the ATM network.

The E3 port option is added to the already supported STM-1 option (Single-

Mode and Multi-Mode).

NIU-12xE1: The NIU-12xE1 card enables a TDM/Leased Line end-to-end

service. The E1 service at the Terminal Station is mapped to the NIU-12xE1

card located on the Base Station Shelf, towards an nxE1/SDH type of

backbone.

Terminal Station IDU with 3 ports configuration options:

2*10/100BaseT on board

2*10/100BaseT on board + 4xE1

2*10/100BaseT on board + 8xE1.

BS-BU N+1 Redundancy: BS-BU N+1 redundancy is available for WALKair

3000 software version 2.00. This redundancy feature has been added to the

previous ODU redundancy feature in order to increase system reliability.

For a given sector, one BS-BU can be defined as “hot standby” for up to four

enabled BS-BUs (either via the WALKnet application or the LCI interface).

In-Band Management Connection via ATM: In-Band Management

Connection via ATM enables the management traffic to be carried over an

ATM VC as part of the ATM traffic. This option has been added to the current

available Out-of-band management option connection, where the Ethernet

interface on the shelf MPU card is connected towards the NMS.

IP Data Performance Monitoring: IP Data Performance Monitoring enables

the collection and presentation of statistics for IP SLA performance data.

Configuration Upload/Download: Configuration Upload/Download enables

the upload of a configuration file from the MPU, and file download back to the

MPU. This provides the administrator the option of holding an archive of all

network configurations for maintenance purposes.

External Clock: A CLOCK IN connector is located on the WALKair 3000 BS

ACM (Alarm and Control Module). Its purpose is to receive a clock from an

external timing source in order to synchronize the system to an accurate

mapping to ATM QoS at the Base Station. QoS using IETF standard

(diffserv).

Unique Features Set

Multi-carrier approach at the base station, FDD & TDMA system, up to six

carriers per sector with single outdoor unit per sector

• Reduces OPEX & CAPEX by saving the number of required ODUs,

roof-top Base Stations and infrastructure

Adaptive / Manual dual modulation scheme (16QAM & QPSK) per

Terminal Station,

• Higher capacity with optimized coverage and system availability

• It improves the operator’s business model by increasing the number of

potential customers per Base Station, saving both the operator’s

CAPEX and the OPEX, by eliminating the need for deployment of new

Base Stations to cover remote customers

6. Functional Considerations

Feature Description

MPU IP Address

Configuring an illegal IP address and Mask to MPU board trough LCI can cause a system malfunction.

Recovery from this situation is only possible by updating the MPU boot parameters

Client Name When configuring a new Client, the Client name MUST start with at least two alpha characters (not numeric).

Hot Swap The opening of a board extraction handle must be followed by board extraction. Opening and closing the handles causes improper operation of the board.

Software download to a BS BU with enabled redundancy

Before downloading software to a BS BU with enabled redundancy, the BS-BU redundancy must be disabled. Otherwise, switchover to the redundant BS BU will occur during the reset.

BS-BU Redundancy

The feature is limited to BS-BU’s in the same sector.

A BS-BU may be redundant to any BS-BU connected to the same IF-MUX.

In-Band management An MPU does not respond to “PING” through In-Band management.

Topology Neither the RFU nor the IF MUX can be deleted after configuration.

Topology

Limitation: one or two 12xE1 NIU in Shelf Domain A (slots 1-6) can work with maximum 2 BS-BUs in Shelf Domain A and 5 BS-BUs in Shelf Domain B (slots 11-16).

Solution: Installing 12xE1 NIU in Shelf Domain B has no limitation on maximum number of BS-BUs in both Domains.

Loopbacks

Setting a loopback requires next operations:

♦ Disable the port

♦ Set the loopback

♦ Enable the port

♦ Configure appropriate services and SLAs

Setting a loopback via Terminal Station LCI does not require the above operations.
