APPENDIX E – INTEROPERABILITY STANDARDS
Page E-4
Local Area Network Access
While no specific LAN technology is mandated, the following is required for interoperability in a joint
environment. This requires provision for a LAN interconnection. Ethernet, the implementation of carrier
sense multiple access with collision detection (CSMA/CD), is the most common LAN technology in use
with TCP/IP. The hosts use a CSMA/CD scheme to control access to the transmission medium. An
extension to Ethernet, fast Ethernet provides interoperable service at both 10 Mbps and100 Mbps. Higherspeed
interconnections are provided by 100BASE-TX (two pairs of category 5 unshielded twisted pair,
with 100BASE-TX auto-negotiation features employed to permit interoperation with 10BASE-T). The
following standards are mandated as the minimum set for operation in a Joint Task Force for platforms
physically connected to a Joint Task Force LAN.
􀂾 ISO/IEC 8802-3:2000 (IEEE Std. 802.3, 2000 Edition).
Gigabit Ethernet extends the speed of the Ethernet specification to 1 Gbps. Gigabit Ethernet is used for
campus networks and building backbones. While no specific LAN/CAN technology is mandated, when
using Gigabit Ethernet (1000 Mbps service) over fiber or Category 5 (CAT5) copper cabling, the
following physical layer and framing standard is mandated:
􀂾 ISO/IEC 8802-3:2000 (IEEE Std. 802.3, 2000 Edition).
DATA LINK STANDARDS
Common Data Link/STANAG 7085
In 1991, and again in 1994, the Assistant Secretary of Defense (ASD) for command, control,
communications, and intelligence (C3I), now ASD for networks and information integration (NII),
mandated the use of common data link (CDL)1 for wideband transmission of imagery and signals
intelligence data from airborne intelligence, surveillance, and reconnaissance (ISR) platforms to ground
processing facilities.2. ASN(C3I) updated these memoranda on 19 June 20013, directing the use of CDL
for all wideband ISR Air-to-Air and Air-to-Ground (but not Air-to-Satellite) data links.
Basic CDL is a full-duplex, jam resistant spread spectrum, point-to-point digital link. The uplink operates
at 200 Kbps, 400 Kbps, 2 Mbps, 10.71 Mbps, 22.4 Mbps, or 45 Mbps. The downlink can operate at 10.71
Mbps, 22.4 Mbps, 45 Mbps, 137 Mbps, or 274 Mbps. In addition, rates of 548 Mbps and 1096 Mbps may
be supported in the future. A Time Division Multiplexer (TDM) scheme is incorporated in the
specification. This allows each CDL system to be configured to support many platforms, sensor systems,
and remote control & reception systems. While this has allowed many applications of CDL to succeed as
individual systems, it has resulted in a host of systems that cannot share capabilities because of the unique
applications of configuration.
As the number of systems using CDL are developed and fielded, this issue has continued to grow. Use of
