This specification establishes the system requirements for a Frequency Division Multiple Access (FDMA) Enterprise Digital Intermediate Frequency (Digital IF) Multi-Carrier Modem (EDIM Modem) System to be used with Department of Defense (DOD) and commercial satellite systems. The EDIM Modem System includes the EDIM Modem and associated Management and Control (M&C) software components.

1.2 General

The EDIM Modem addresses L-Band port congestion at DOD SATCOM gateways by offering a multi-carrier general purpose FDMA modem capability for use in uncontested environments. The EDIM Modem is also a dual IF modem with an L-Band IF interface and a Digital IF interface. This dual IF capability enables and accelerates the migration of DOD SATCOM gateway architectures from L-Band media to Digital IF media, which further addresses L-Band port congestion and begins to address resilience.

1.3 Multi-Carrier Modem Operation

The EDIM Modem is a fully integrated multiple carrier modem addressing growing DOD Enterprise SATCOM needs for high-density, high-performance Internet Protocol (IP)-centric FDMA modem operations. The EDIM Modem supports multiple point-to-point SATCOM links by carrying Ethernet data traffic over multiple carriers employing both L-Band and Digital IF interfaces. The ability to support multiple carriers over L-Band immediately addresses L-Band switch congestion issues at Enterprise SATCOM gateways. The EDIM Modem is an operator-friendly upgradeable platform intended to introduce various new modem capabilities, both immediately and through subsequent upgrades.

1.3.1 Modem Emulations

The EDIM Modem supports an efficient subset of NATO STANAG 4486 Ed4 (Enhanced Bandwidth Efficient Modem, a.k.a. EBEM) waveforms. Provisions for ensuring high performance efficient operation include integrated interference mitigation.

1.3.2 Data Traffic Cover

The EDIM Modem is intended for operation with encrypted (i.e., black) data traffic.

The EDIM Modem provides encryption for all its carriers for purposes of obscuring headers to prevent adversary data traffic analysis. Data traffic cover is in accordance with (IAW) NATO STANAG 4486 Ed4 for interoperability with EBEM.

The EDIM Modem is to be certified at Security Level 2 IAW Federal Information Processing Standards (FIPS) Publication (PUB) 140-3.

Section 4: EDIM Modem System Specification

1.3.3 Growth in Link Rates

EDIM Modem provides for growth in link rates available to users, including higher maximum data traffic rates and symbol rates. Provisions for raising link rates include offering the Digital Video Broadcasting Second Generation Extensions (DVB-S2X) waveform, IAW ETSI EN 302 307-2, at the discretion of the Contractor.

1.4 Digital IF Migration

Digital IF Enterprise terminal infrastructure is key to supporting DOD SATCOM growth and resilience. The EDIM Modem supports the transition from L-Band to Digital IF infrastructures by offering dual IF interface sets. Operation over the L-Band IF is compliant with MIL-STD-188-165B. The Digital IF interface is IEEE-ISTO 4900-2021 Digital IF Interoperability Standard (DIFI Standard) compliant to ensure interoperability with an existing base of commercial equipment and with subsequent emerging SATCOM Digital IF infrastructure equipment.

Digital IF performance supports end-to-end performance of Digital IF signal chains equivalent to or exceeding the performance required of corresponding L-Band signal chains.

1.5 Enterprise Applications

The initial application of the EDIM Modem is for Enterprise Earth terminal deployment.

The Government plans to install the EDIM Modem in DOD Joint SATCOM Gateways that access Wideband Global SATCOM (WGS) and commercial satellites. The EDIM Modem operates with earth terminals in the SHF (C, X, Ku and Ka) band as a replacement for the EBEM, which is reaching its end of life. The EDIM Modem is packaged in a 1RU chassis for efficient modular deployment, maximizing capability provided relative to rack space occupied. The EDIM Modem is mounted in EIA/ECA-310-E compliant racks.

1.6 Management and Control Flexibility

The EDIM Modem supports remote management and control, future centralized power management, and lights out operation.

1.7 Future Applications

The Government may consider revised or upgraded versions of the EDIM Modem in the future for application in shipboard, land mobile, airborne SATCOM, special missions, and virtualization. Such revisions may include upgraded capabilities and/or new size, weight and power (SWaP) requirements.

1.8 Upgradability

The EDIM Modem is software (SW) / firmware (FW) upgradable and open to additional capabilities. The SW/FW upgrade process will be simple, local and remote capable, and over-the-air capable.

Section 4: EDIM Modem System Specification

• factory reset initiated IAW Section 3.3.4.7

These indications may be presented on the OI, through the optional serial M&C port, or directly on the EDIM Modem front panel. Should these indications be presented directly on the EDIM Modem front panel, then the term “visual indication” may be applied in the most general sense.

Front panel visual indication methods may be duplicated when the underlying context is sufficient to differentiate between the conditions indicated. For example, “boot-up in progress” could be the same indication as “factory reset initiated” because the EDIM Modem has just been powered on in the first case, and a factory reset has just been initiated in the second case.

Section 4: EDIM Modem System Specification

In the absence of external time sources, it shall be possible for the operator to configure EDIM Modem system time of modems individually, and to configure modem suites under centralized management. Upon loss of external time sources, system time shall be maintained to a degree adequate to support all EDIM Modem functions.

3.2.1.2 Frequency Base

The EDIM Modem shall monitor, accept and reconcile frequency reference information from the 5/10 MHz timing reference through the 5/10 MHz timing port indicated in Section 3.1.1.2.6.1.

The EDIM Modem shall maintain internal frequency reference adequate to support:

• all management and control interface functions and performance

• all Ethernet data traffic interface functions and performance

• all IF interface functions and performance

3.2.2 Data Traffic Rate Estimation

The EDIM Modem shall estimate (average and report) the rate of actual data traffic (i.e., the incident on the data traffic ports indicated in Section 3.1.1.2.1), as intended for each uplink carrier. Data traffic rate estimation will be used to:

• assess link utilization

• eventually support Dynamic Resource Allocation (DRA) of satellite power WRT data traffic demand and link conditions IAW Section 3.7.2.3. (Note:

Dynamics of data traffic rate estimation shall be tailored to this purpose.)

3.2.3 L-Band IF Interface

The EDIM Modem shall support all specified L-Band modem function, at least within any single tunable 600 MHz interval, from at least 950 to 2000 MHz over the L-Band IF interface set indicated in Section 3.1.1.2.2. L-band performance specified in this document shall be met for all waveforms whose −25 dBc BWs are contained, at least within any single tunable 600 MHz interval, between 950 and at least 2000 MHz.

3.2.3.1 L-Band IF Non-Damaging Input Power

The EDIM Modem shall not be damaged by a continuous input of up to +25 dBm on the L-Band IF Receive interface indicated in Section 3.1.1.2.2.

3.2.3.2 L-Band IF Isolation

Isolation between L-Band ports shall exceed 74 dB.

3.2.4 Digital IF Interface

The EDIM Modem shall support all modem functions over the Digital IF interface indicated in Section 3.1.1.2.3. Digital IF performance specified in this document shall be met for all waveforms whose -25 dBc BWs are contained within
