1. Introduction

1.1 Product Overview

This section provides a brief overview of the IP-20 products described in this

document. A separate Technical Description is available for each product,

providing a full description of the individual product and its specifications.

1.1.1 FibeAir IP-20C Ceragon’s FibeAir IP-20C sets a new standard in microwave transmission,

combining MultiCore radio technology with QPSK to 2048 QAM modulation.

IP-20C breaks capacity barriers, offering a virtual fiber solution in licensed

frequency bands. Its versatility makes it ideal for a wide variety of cost-effective

deployment scenarios including macrocell backhaul, small-cell aggregation, and

emerging fronthaul applications.

IP-20C can deliver multi-Gbps capacity on a single frequency channel, setting a

new standard for efficient spectrum use. IP-20C’s unique MultiCore radio architecture is based on an advanced parallel radio processing engine, built around Ceragon’s in-house chipsets. The result is a superior radio

performance with reduced power consumption and form-factor.

The IP-20C services model is premised on supporting the standard MEF

services (MEF 6, 10), and builds upon this support by the use of very high

granularity and flexibility. Operationally, the IP-20C Ethernet services model

is designed to offer a rich feature set combined with simple and user-friendly

configuration, enabling users to plan, activate, and maintain any packet-based

network scenario. The FibeAir series ╉pay-as-you-go╊ activation key model further enables

operators to build for the future by adding capacity and functionality over

time to meet the needs of network growth without requiring additional

hardware. Additionally, IP-20C’s MultiCore architecture enables operators to start with a single core with the option of enabling the second core remotely

when network capacity requirements increase.

1.1.2 FibeAir IP-20S

FibeAir IP-20S provides the same basic feature set as the IP-20C, including

QPSK to 2048 QAM modulation, the advanced IP-20 Ethernet services model,

ease of installation and operation, and more, in a single-carrier package.

1.1.3 FibeAir IP-20E

FibeAir IP-20E is a high-capacity, all-outdoor Ethernet backhaul product

designed to operate in the E-Band frequency range. IP-20E provides over

1 Gbps capacity over 250 MHz channels, with modulations of 4 – 128 QAM.

IP-20E utilizes the same CeraOS software as the rest of the FibeAir IP-20

platform, enabling it to provide the same Ethernet services model and other

advanced radio, Ethernet, and management features as IP-20C and IP-20S.

20, and 30 MHz channels using non-XPIC scripts without ATPC and

without Multi-Carrier ABC.

2. Other than the links described above, interoperability over the radio

between IP-20C/S and IP-20N/G/GX+RMC-A/B, as well as interoperability

between IP-20C and IP-20S, is not supported for this SW Release.

3. MIMO 4x4 is only supported when both Master and Slave share the same

SW Release. The upgrade procedure must be performed simultaneously

on the Master and Slave units.



9. Version Upgrade Compatibility

The following table indicates software upgrade compatibility. In some cases,

you cannot upgrade directly from one version to another. Rather, you must

upgrade to an intermediate version, and then to the higher version. For

example, as shown in the table, to upgrade from version 7.0 to version 8.2, you

must first upgrade from version 7.0 to version 7.5.2, then from version 7.5.2 to

version 7.7.5, then from version 7.7.5 to version 8.0, and finally, from version

8.0 to version 8.2.

It is recommended to perform each upgrade on all units in the link and then to

perform the additional upgrade on all units in the link.

When working with IP-20C’s carriers in 2+0 SP/DP mode, the user can activate the Multi-Carrier ABC mechanism which enables optimal packet per

packet distribution over the radios†.

In release C7.7.5, a revision of this mechanism was implemented to

improve future SW maintainability.

The following table describes several SW over-the-link compatibility

scenarios of the Multi-Carrier ABC mechanism.

Medium

Sometimes, initiating a software upgrade

procedure for HSB can take up to 10

minutes.

Wait up to 20 minutes for

the installation process to

begin on the Active unit.

After the software

installation process has

been successfully

completed on the Active

unit and the unit has

rebooted, the Standby unit

becomes the Active unit.

After the unit that was

originally the Active unit

has returned online after

reboot, download and

install the new software

version to the unit that was

previously the Standby unit

and is now the Active unit.

Note: The installation process will again try to install to mate, but since the unit that was formerly the Active unit has already been upgraded, the installation process will only be performed on the currently Active unit.

21. 69694 Radio Loopback

XPIC Medium

RF loopback does not function properly in

XPIC links.

To perform an RF loopback in

an XPIC configuration, you

must first disable XPIC.

Note: When working in ACM fixed mode, the user must mute one radio carrier on the local and remote sides of the link before disabling XPIC.

After finishing loopback testing,

the user must re-enable XPIC

and afterwards unmute the

muted radio carrier on both

sides of the link.

Enabling and disabling XPIC

will cause a hardware reset.

29. 91975 Management Medium

Local-remote communication will not

function if either unit in the link is running

software version 7.0.

Upgrade both sides of the radio

link to the new software

version. To avoid loss of in-

band management, the remote

side must be upgraded first.

FA IP-20C


Resetting only the slave unit in MIMO 4x4

mode will cause the state of the master

unit to revert to half capacity. The master

unit stays in half capacity mode until the

user manually resets MIMO.
