1.1 Network Positioning

The OptiX RTN 380 can provide large-capacity backhaul microwave links or aggregation links

on a mobile communications network or a private network, or replace optical fibers to transmit

CPRI signals between baseband units (BBUs) and remote radio units (RRUs) in a distributed

base station system to achieve longer transmission of RRUs.

As E-band full outdoor radio equipment, the OptiX RTN 380 has the following characteristics:

l The OptiX RTN 380 operates at 71-76 GHz or 81-86 GHz frequency bands. It features

large capacity, low inter-site interference, and rich frequency spectrum resources, as

compared with radio equipment that operates at 6-42 GHz frequency bands. Therefore,

OptiX RTN 380s can form a backhaul network for base stations densely deployed in a city

and provide large-capacity backhaul links for aggregation sites. In addition, the OptiX RTN

380 can provide high-bandwidth microwave links for transmitting Ethernet services on a

metro optical Ethernet in areas where optical fibers are difficult to lay out.

l As compact full outdoor radio equipment, the OptiX RTN 380 integrates all functions in a

chassis and does not need an extra installation site. Therefore, it allows carriers to construct

and operate networks at lower costs than traditional split radio equipment.

On a mobile communications network, OptiX RTN 380s are mainly used to:

l Provide large-capacity backhaul microwave links for 3G/LTE base stations especially those

that are densely deployed in urban areas. See Figure 1-1.

l Provide large-capacity aggregation links for 3G/LTE base stations and implement multi-

direction aggregation when working with OptiX RTN 900s. See Figure 1-2.

lProvide microwave links between BBUs and RRUs in a distributed base station system totransmit CPRI signals to achieve longer transmission of RRUs. See Figure 1-3.

2.1 Capacities

This section provides the air interface capacity and Ethernet service switching capacity of OptiX

RTN 380.

Air Interface Capacity

l When transmitting CPRI services, OptiX RTN 380 supports one channel of 1.25 Gbit/s or

2.5 Gbit/s CPRI services.

l When transmitting Ethernet services, OptiX RTN 380 supports approximately 2.5 Gbit/s

throughput at most.

OptiX RTN 380 supports Ethernet frame header compression at air interfaces. It can increase

air-interface capacity when the equipment uses a low-order modulation scheme or when the

channel spacing is 250 MHz.

NOTE

6.1.1 Radio Working Mode provides air interface capacities in various working modes.

Ethernet Service Switching Capacity

OptiX RTN 380 with its built-in Ethernet switching unit has an Ethernet service switching

capacity of 5.5 Gbit/s.

2.2 AMACAdaptive modulation and adaptive channel space (AMAC) is a technology that automatically

adjusts the working mode based on channel quality. AMAC includes the AM and AC functions.

AM

When AM technology is enabled and the same channel spacing is used, the radio service

bandwidth varies according to the modulation scheme. The higher the modulation efficiency,

the higher the bandwidth of the transmitted services. With quality of service (QoS) technology,

packet services are groomed to queues with different priorities. Services in different queues are

then transmitted to the microwave port after the queue-scheduling algorithm has been run. Under

all channel conditions, the service capacity varies according to the modulation scheme.

l When conditions for channel quality are favorable good (such as on sunny days), the

equipment uses a higher-order modulation scheme to transmit more user services. This

improves transmission efficiency and spectrum utilization of the system.

l When conditions for channel quality are unfavorable (such as on stormy or foggy days),

the equipment uses a lower-order modulation scheme to ensure that higher-priority services

are transmitted first. If some lower-priority queues become congested due to a lack of

available bandwidth, some or all interfaces in these queues are discarded. This method

improves the anti-interference capabilities of a microwave link and ensures link availability

for high-priority services.

The AM technology used by the OptiX RTN 380 has the following features:





16


26/168

l Uses QPSK Strong, QPSK, 16QAM, 32QAM, 64QAM modulation schemes. Compared

with QPSK, QPSK Strong, using different parameters in forward error correction (FEC)

coding, has stronger error correction capability, and therefore has better receiver sensitivity.

It has, however, less air interface bandwidth.

l Can configure both the lowest-order modulation scheme (also called reference scheme or modulation scheme of guaranteed AM capacity) and the highest-order modulation scheme

(also called nominal scheme or modulation scheme of full AM capacity).

l Can switch modulation schemes without changing the transmit frequency, receive

frequency, or channel spacing.

l Switches modulation schemes step-by-step.

l Features hitless shifting. When the modulation scheme is downshifted, low-priority

services are discarded while high-priority services are not affected. Shifting is successful

even when 100 dB/s channel fading occurs.

ACAC is the enhancement of AM. If the lowest-order modulation scheme is set to QPSK Strong,

the AM function downshifts the modulation scheme to QPSK Strong when channel quality

deteriorates. Then, the AC function downshifts the channel spacing. The equipment uses the

available bandwidth to transmit high-priority services, reducing the impact of channel quality

deterioration on service signals.

l Channel spacing shifting is supported only when the modulation scheme downshifts to the

lowest-order modulation scheme QPSK Strong.

l When conditions for channel quality are unfavorable (such as on stormy or foggy days),

the equipment downshifts the channel spacing, which reduces the impact of channel quality

deterioration on service signals.

l AC features hitless shifting. When the channel spacing is downshifted, low-priority services

are discarded while high-priority services are not affected. Shifting is successful even when

100 dB/s channel fading occurs.

2.3 Automatic Transmit Power Control

Automatic transmit power control (ATPC) is a method that uses received signal level (RSL) of the receiver to adjust transmit power within the ATPC control range. This feature reduces

interference to neighboring systems and residual bit error rate (BER).

When ATPC is enabled:

l If the RSL is 2 dB or more than 2 dB less than the value halfway between the upper and

lower ATPC thresholds, the receiver instructs the transmitter to increase transmit power so

that the RSL does not deviate more than 2 dB from the halfway value.

l If the RSL is 2 dB or more than 2 dB greater than the value halfway between the upper and

lower ATPC thresholds, the receiver instructs the transmitter to reduce transmit power so

that the RSL does not deviate more than 2 dB from the halfway value.

Figure 2-2 shows the relationship between the RSL and the transmit signal level (TSL).

2.14 Security Management

OptiX RTN 380 works with its network management system (NMS) to prevent unauthorized

logins and operations, ensuring equipment management security.

Overview of Hardware Security

The following hardware security measures are provided by OptiX RTN 380:

l Microwave ports: The FEC encoding mode is adopted and the adaptive time-domain

equalizer for baseband signals is used. This enables the microwave ports to withstand strong

interference. An interceptor cannot restore the content in a data frame if coding details and

service configurations are not obtained.

l Modular design: Control units are separated from service units and service units are

separated from each other. In this manner, a fault on any unit can be properly isolated,

minimizing the impact of the fault on other units in the system.

l CPU flow control: Data flow sent to the CPU for processing is classified and controlled to

prevent the CPU from being attacked by a large number of packets. This ensures that the

CPU operates properly under attacks.

l USB port control: The USB port is disabled when the USB port is not used, to avoid invalid

access.

Overview of Software Security

OptiX RTN 380 is positioned at the transport layer of a communications network. It provides

high-capacity and high-reliability transparent transmission tunnels, and is practically hidden

from view. Therefore, the transmission tunnels are not easily exposed to external attacks.





31


41/168

OptiX RTN 380 processes two categories of data: O&M data and service data. The preceding

data is transmitted over independent paths and does not affect each other. This enables services

running on OptiX RTN 380 to be processed on two planes:

l Management plane

l Data plane

The management plane provides access to the required equipment and management functions,

such as managing accounts and passwords, communication protocols, and alarm reporting.

Security features on the management plane implement security access, integrated security

management, and all-round security audits. The Secure Sockets Layer (SSL) features provide

security access to the required equipment. The Remote Authentication Dial-In User Service

(RADIUS) feature implements centralized security authentication for the equipment on the

entire network. The Syslog feature implements offline storage of more security-related logs for

audits.

The data plane processes the service data flow entering the equipment and forwards service

packets according to the forwarding table. Security features on the data plane ensure

confidentiality and integration of user data by preventing malicious theft, modification, and

removal of user service packets. These features ensure stable and reliable operation of the

forwarding plane by protecting forwarding entries against malicious attacks and falsification.

The data plane provides:

l User service separation methods

l Access control methods

l Methods for controlling and managing ingress and egress bandwidth of the equipment to

ensure reliable operation, such as flow control and quality of service (QoS).

Table 2-8 lists the security functions provided by OptiX RTN 380.
