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.

3. New Features
3.1 AES-256 Payload Encryption
From CeraOS 8.3, FibeAir IP-20C and IP-20S support radio payload encryption using AES-256. The Advanced Encryption Standard (AES) is defined in Federal Information Processing Standard Publication 197 (FIPS 197) for symmetric encryption. AES-256 is widely considered to be secure and efficient and is therefore broadly accepted as the standard for both government and industry applications.
For more information on AES-256 Payload Encryption, refer to AES-256 Payload Encryption in the relevant Technical Description.
For instructions how to configure AES-256 Payload Encryption, refer to section 5.5, Configuring AES-256 Payload Encryption in the IP-20C/S/E User Guide.
Note: The AES-256 payload encryption feature is a controlled item under applicable Export Laws. Please contact your Ceragon representative to confirm that the encryption feature can be delivered.
3.2 FIPS 140-2
From CeraOS 8.3, FibeAir IP-20C and IP-20S can be configured to be FIPS 140-2 level-2-compliant, in specific hardware and software configurations, as described in this section
Note: FIPS certification by NIST is pending.
The objective of FIPS 140-2 is to provide a standard for secured communication devices, with an emphasis on encryption and cryptographic methods. The FIPS standards are promulgated by the National Institute of Standards and Technology (NIST), and provide an extensive set of requirements for both hardware and software. For a full list of FIPS requirements, refer to the Ceragon IP-20 FIPS 140-2 Security Policy, available upon request.
It is the responsibility of the user to ensure that the above FIPS requirements are met.
For an IP-20C or IP-20S node to be FIPS-compliant, the unit must be FIPS-compliant hardware. A FIPS-compliant unit has a unique part number ending in the letters AF, in the following format: IP-20C-***-AF or IP-20S-***-AF.
Special labels must be affixed to a FIPS-compliant IP-20C or IP-20S unit. These labels are tamper-evident and must be applied in such a way that it is not possible to open or tamper with the unit. Replacement labels can be ordered from Ceragon Networks, part number BS-0341-0. Tamper-evident labels should be inspected for integrity at least once every six months. For further details, refer to the FibeAir IP-20C Installation Guide.
For more information on FIPS 140-2 compliance and the specific hardware and software requirements per IP-20 product, refer to FIPS 140-2 Compliance in the relevant Technical Description

Ceragon Proprietary and Confidential Page 12 of 44
For instructions how to enable FIPS operation on an IP-20 unit, refer to Section 2.13, Operating in FIPS Mode, in the IP-20C/S/E User Guide.
3.3 Quick Multi-Carrier ABC Configuration Wizard
From CeraOS 8.3, the Web EMS for IP-20C includes a wizard that guides the user through quick creation of Multi-Carrier ABC groups.
For instructions how to use the Quick Link Configuration wizard, refer to section 3.2, Configuring a Link Using the Quick Configuration Wizard in the IP-20C/S/E User Guide.

4. Modified Features
4.1 LAG Option Added to Quick Link Configuration Wizards
CeraOS 8.3 adds the ability to use LAGs in the Web EMS’s 1+0 and 1+1 Quick Configuration wizards. Users can configure links using LAG groups in place of simple Ethernet interfaces. In addition, the Quick Configuration wizard enables users to create a LAG within the wizard’s link configuration workflow.
For instructions how to use the Quick Link Configuration wizard, refer to section 3.2, Configuring a Link Using the Quick Configuration Wizard in the IP-20C/S/E User Guide.

MIMO ATPC is not supported in MIMO configurations.
LAG Multi-Carrier ABC cannot be LAG or any other logical group Service Point
Script 1501 (80 MHz script) The user can configure the system to work up to profile 10 even though the
highest supported modulation for this script in this release is profile 8 (1024
QAM).
Script 1501 (80 MHz script) For 2+0 IP-20C configurations, the 80 MHz script must be assigned to both
carriers. An IP-20C cannot be configured to operate with the 80MHz script on
one of the carriers and a different script on the other carrier.
80 MHz scripts do not operate in Multi-Carrier ABC mode.
80 MHz scripts are only supported on wide-channel radios, as indicated by a
“w” in the Marketing Model.
MIMO is not supported for 80 MHz channels.
Scripts 1523 (3.5 MHz),
1508 (7 MHz), & 1509
(14MHz)
The maximum ACM profile must be greater than 3 in order to work with Multi-
Carrier ABC
Software Upgrade During software installation:
DO NOT reboot the unit during the SW installation process. As soon as the
process has been successfully completed, the unit reboots automatically.
In rare cases, the installation process can take up to 30 minutes.
Only in the event that the installation has not been successfully completed and
more than 30 minutes have passed can the unit be rebooted.
RADIUS/HSB Protection RADIUS authentication is not supported with HSB radio protection.

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 8.3, 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 8.3.
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.

9.1.1 Multi-Carrier ABC Version Compatibility
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 radios2.
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.
Site A SW version Site B SW version Multi-Carrier ABC Compatibility
Case 1 Prior to C7.7.5 Prior to C7.7.5 OK
Case 2 Prior to C7.7.5 C7.7.5 Not Compatible
Case 3 C7.7.5 C7.7.5 or higher OK
