he Series 875 LAN+T1 Microwave Radio System is a low cost, high bandwidth, radio system capable of transporting full bandwidth LAN traffic and T1 telephony up to 3 miles. The radio system offers the following features:

The Ethernet interface of the radio system supports all 802.3 protocols and includes an AUI connection to network devices and BNC connections to the microwave unit. The T1 data interface of the radio system supports Bell Standard 100 ohm, two-wire twisted pair designed to connect to telephony and multimedia interfaces. No on-site programming is required and no additional test equipment is needed.

The Series 875 LAN+T1 system provides point-to-point connections for hubs, bridges, routers and repeaters allowing full 10 Mbps Ethernet connectivity. The 875 LAN+T1 interface has been designed to connect directly to standard T1 PBX's, Channel Banks or Telecom Multiplexers without the need for additional equipment. The 875 LAN+T1 also supports full duplex Ethernet LAN operation (20 Mbps) allowing connection to full duplex devices such as Ethernet switches and adapters. Multiplexed LAN and MULTIPLE T1 access is also available for telephony and multimedia applications.

The Series 875 LAN+T1 is designed for rapid installation and alignment without special tools or test equipment. Rugged, modular radio design for ease of service and field support for years of trouble free operation in harsh weather conditions.
