INTRODUCTION
The MDR-8000 family of microwave radios is specifically designed to satisfy the evolving
needs of public, private, government, and international networks. Each DS1/E1 radio offers the
flexibility of 2, 4, 8, 12, 16 DS1s or E1s to meet the need for low capacity domestic or inter-
national systems. Each DS3 radio offers up to three DS3s with equal number of wayside DS1s to
meet domestic high capacity system requirements. Each OC3/STM-1 radio offers one or three
STS1s with equal number of wayside DS1s or E1s to meet domestic or international
Synchronous Optical Network (SONET) system requirements. The MDR-8000E Ethernet radio
provides transport for IP/packet data in licensed and unlicensed frequency bands. The radio
supports 10baseT, 100baseT, and 1000baseT interface rates with auto-negotiation and can be
configured to transport low and high capacity data at RF frequencies in the 2, 4, 5, 6, 7/ 8, and
10/11 GHz bands.
The number of channels transmitted and the RF channel bandwidth depend on the capacity keys
installed in the transmitter and receiver modules. The modulation formats are 32 or 128 TCM
(DS1/E1), 64 QAM (DS3), and 128 TCM (OC3/STM-1). Growth in DS1/E1 system capacity can
be performed in service and requires only exchanging capacity keys. Growth from DS1/ E1 to
DS3 system capacity is an out-of-service procedure and requires exchanging modules and
capacity keys. Changing to OC3/STM-1 system capacity is performed out-of-service and
requires exchanging modules, and capacity keys.
All radios are available in 1:0 non-standby (NS) and 1:1 hot-standby (HS) and frequency diver-
sity (FD). The HS version allows for troubleshooting and module replacement, on an in-service
basis. Space diversity can be added to any of the three basic configurations. In addition to the
three basic configurations, the OC3/STM-1 radio is available with a 0:2 dual channel (no pro-
tection) equipment configuration and the protected OC3/STM-1 radio is also available in a 2 X
4-fiber or 4-fiber cable configuration.

UNLICENSED RADIO
The MDR-8X05U/8X02U (unlicensed) radio provides fast deployment of service with
microwave radio No license and small antennas (no FCC requirements) allow immediate turnup.
After the license is received, the unlicensed radio can be easily converted to the lower 6 GHz
licensed band.
