PASOLINK + provides ideal intranet-intranet and intranet-public network

connection solution

Dedicated line service

The importance of IT in business todaydemands that most businesses

build private networks. PASO LIN K + enables the efficient construction of

low-cost, highly secure transmission networks.

sWireless SDH / ATM Rings (Fig. 3)

PASOLINK + series systems can provide an ST M-1 optical interface,

allowing them to be part of the optical SDH ring. Particularlyin urban

areas where it is difficult to install optical fiber due to cable duct

problems, PASOLIN K + makes quick, economical installation possible.

s Last Mile connection (Fig. 3)

In locations where there are long-distance trunk lines but no local lines,

PASOLINK + provides the crucial Last M ile connection.

For point-to-point microwave transmission, you want a system

that offers high-speed transmission capability, easy installation,

scalabilitya nd cost-effective performance. In other words, you

want NECs PASOL INK + point-to-point dig ital microwave radio

relaysystem.

Our PASOLINK + series features highly reliable, intelligently

designed PDH /SDH radi o relaytransmission equipment offering

traffic capacityfrom 8 x 2, 16 x 2, 52, 155 and

2 x 155 Mbp s traffic capacities for a wide selection of access

frequencies in the 4 38 GH z band. And the newlyad opted

10/100BASE-TX interface delivers increased throughput,

reducing bottlenecks in high-volume networks.

By employing a compatible ODU , system upgrades for

higher capacityor modulation are easilyaccomplished this

scalabilityi s extremely valuable as the volume of multimedia

traffic continues its meteoric rise.

Whats more, the PASO LINK + series is fully compatible with

NEC s PNMS (PA SOL INK Network Management System),

making alarm/event, configuration and securitymanagement, as

well as performance monitoring and other functions, p ossible

via a personal computer even a laptop.

s Transparency of variable protocols and technologies

(IP, ATM, FR,Voice)

sBroad range of payload capacities

P DH ( 16QA M ): 8E1 or 16E1 (Bit rate-free version available)

SDH STM -0 (32QAM) : 51.84 Mbps

SDH STM-1/OC3 (32MLCM/128QAM ): 155.52 Mbps

SDH 2 x STM -1/OC3 (128QAM ): 2 x 155 Mbps

(co-channe l transmission)

sCommon platform architecture

PASOLINK + equipment shares a common platform. The narrowband

STM -1 ODU can be used for all systems, and an economical OD U is

also available for PDH (16QA M) , STM -0 (32QAM ) and STM-1/OC3

(32M LCM ) systems. Therefore, the expansion from PDH to STM -0, STM-0

to STM-1/OC 3 can be achieved simplyb yreplacing the ID U.

sSystem configuration variations

1+ 0 system

1+ 1 hot standbysystem

Space or frequencydiversitysystem

2+ 0 co-channel transmission system

sHigh system gain and high spectrum efficiency selectable

sEasy to install

Compact, lightweight, and split mounting design with single

IF cable

Field-tunable local oscillator (synthesizer) within a specified

sub-band

s TX power control

Automa tic Transmitter Power Control (ATP C) reduces interference,

improves residual BER performa nce and alleviates upfade problems.

sHigh-speed Ethernet interface

10/100BASE -TX Ethernet interface is available for the STM -1/OC 3

system.
