TDM4Link Family
Point-to-Point 4xT1/E1/EtherNet Digital Microwave Radio Systems
WHAT IS THE TDM4LINK FAMILY OF RADIO SYSTEMS?
The TDM4Link family is an advanced line of broadband radio communication systems, designed for delivery of packetized Ethernet data. Customers can choose from versions offering three different data rates: T4-4500 (45Mb/s), T4-2500 (22.5Mb/s) or T4-1200 (11.25Mb/s). The lower rate products are field upgradeable to deliver the higher rates. All radios offer full-duplex, Telco grade performance.

Each system consists of an outdoor point-to-point microwave radio (ODU) connected to an indoor, rack-mountable access panel (IDU). The IDU provides connections for up to four mix and match T1/E1 circuits. Excess bandwidth is available via an RJ-45 port. The IDU powers the ODU using Power over CAT5. This two-part flexible architecture allows optimal radio placement for maximum performance.
TDM4Link systems operate in the license-free band, and operators can choose versions transmitting in the 5.3 GHz UNII band or in the 5.8 GHz ISM band. The outdoor radios can be ordered with either an integral antenna, or an external antenna connector.
TDM4Link indoor units mount easily onto standard telco racks, and with a narrow form factor, operators can place two units side by side using only one rack unit (1.75").
WHY AERAS WIRELESS BROADBAND?
Aeras Networks' TDM4Link systems deliver up to 45 Mb/s full duplex backhaul bandwidth with powerful Forward Error Correction (FEC).
