CFM–LM Equipment

Overview

The CFM–LM digital microwave radio products can be employed in various modern applications
including private data/voice networks, cellular networks, utility private networks, PBX trunk
connectivity, access to high–speed networks of providers of data services (IP, FR, etc.).
The choice of antennas for the CFM–LM radio model solely depends on the availability
requirements for particular installation or service type.
CFM–LM System Components:
The typical CFM–LM terminal configuration consists of an Indoor Unit, an Outdoor Unit and an
antenna.
The Outdoor Unit is either directly connected to the antenna or installed separately. In the latter
case a flexible waveguide is used to interconnect the ODU with the antenna.
The ODU is interconnected with the IDU with a single coaxial cable.
The following LM Indoor Unit models are available:
•
The CFM-8-REB, - Remote Ethernet Bridge IDU, provides full radio capacity of 8 Mbps to
10Base–T UTP Ethernet interface on the LAN side;
•
The CFM-34-REBM, - modular Fast Ethernet bridge IDU, provides 100Base-Tx UTP LAN
interface plus two interface slots that can be equipped with two interface modules (V.35, E1
or 10Base-T Ethernet) providing additional traffic interfaces with a maximum capacity of 2
Mbps each;
•
Modular multiplexer IDUs: the following multiplexer IDUs are available:
CFM-8-MUX, - modular IDU, can be equipped with 4 interface modules (V.35, E1 or
−
10Base-T Ethernet) providing maximum WAN data rate of 8 Mbps;
CFM-16-MUX, - modular IDU, can be equipped with 4 interface modules providing
−
maximum WAN data rate of 16 Mbps;
•
E1 Indoor Units: the following E1 interface IDUs are available:
CFM-8-4E1, - fixed configuration multiplexer, provides multiplexing of 4 E1 channels
−
into a single 8 Mbps stream (8448 kbps total throughput, 8192 kbps payload);
CFM-16-8E1, - fixed configuration multiplexer, provides multiplexing of 8 E1 channels
−
into a single 16 Mbps stream (16896 kbps total throughput, 16384 kbps payload);
CFM-34-16E1, - fixed configuration multiplexer, provides multiplexing of 16 E1
−
channels into a single 34 Mbps stream (34368 kbps total throughput, 32768 kbps
payload);
•
CFM-M-MUX, - modular IDU, can be equipped with 4 interface modules (V.35, E1, 4xE1 or
2-port 100Base-T), supports WAN data rates of 8 Mbps, 16 Mbps and 34 Mbps;
•
CFM-MP-MUX, modular 1+1 IDU (2U high), can be equipped with 4 interface modules
(V.35, E1, 4xE1 or 2-port 100Base-T), supports WAN data rates of 8 Mbps, 16 Mbps and 34
Mbps;
