875 LAN+T1 Microwave Radio System
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.
