1 CFM-34-REBM Fast Ethernet Bridge Indoor Unit
Overview
Proprietary notice
The specifications or information contained in this document are subject to change without notice due to continuing introduction of design improvements. If there is any conflict between this document and compliance statements, the latter will supersede this document.
The following document is dedicated to the CFM series Modular Remote Fast Ethernet Bridge Indoor Units, describing the built-in management system, configuration functionality, hardware features, etc.
This document describes particularly the CFM-34-REBM modular bridge. The CFM-34-REBM Fast Ethernet Bridge is part of SAF Tehnika’s CFM series digital
microwave radio product family and serves as Indoor Unit (IDU) providing:
- Means of interconnecting Outdoor Unit (ODU or Radio) and user equipment;
The CFM-8-REBM, the CFM-16-REBM and the CFM-34-REBM is intended for use with the CFM-LM Radio.
- Local management functionality. Current document covers versions 3.12 and above for the management controller
software of all modular Ethernet bridge models.
The Ethernet bridge (henceforth in some places referred as primary bridge) is built on the High performance full remote Ethernet bridge chipset. The Bridge is fully compatible with IEEE802.3/Ethernet V.2 specifications. It has a 100Base-Tx LAN interface (UTP) implemented on RJ-45 connector.
Wire speed screening and bridging is performed, depending on LAN port setting at 100 Mbps (HDX) or 200 Mbps (in full duplex topology). The bridge automatically detects FDx/HDx mode and 10/100 Mbps LAN speed.
WAN link data rate is 34 Mbps, which is equal to full radio channel capacity available. The bridge automatically learns MAC addresses on the LAN to which it is connected
and forwards only those frames destined for another LAN. The LAN table stores up to 1000 addresses and is automatically updated.
Filtering and forwarding is performed at the maximum theoretical rate of 150,000 frames per second (wire speed). The buffer can hold 170 frames with a throughput latency of one frame. Forwarding can be disabled for multicast and broadcast messages from LAN to WAN. Delay time is one Ethernet frame.
The Ethernet Bridge is of the so-called “store and forward” type, - the packet is placed in buffer, examined, and forwarded to another port. The bridge supports packets up to 1534 bytes long (including VLAN tagged packets) compared to Ethernet standard value of 1518.
Feature summary:
− Full compatibility with IEEE 802.3 / Ethernet V.2
− VLAN tagging support
− 100Base-Tx (UTP) LAN interface
− Auto negotiation
− 150,000 frames per second filtering and forwarding rate
− 170-frame buffer
− 1000 MAC address LAN table
− Automatic learning and aging
The total WAN data rate of the CFM-34-REBM Fast Ethernet bridge is 34 Mbps. The bridge provides two interface slots and thereby can be equipped with two interface modules providing additional traffic interfaces with a maximum capacity of 2 Mbps each. The slots can be switched on and off. The WAN data rate of the primary Ethernet traffic (Fast Ethernet) will decrease by 2 Mbps per each active slot.

Label Color Description
RA Red Radio Alarm LED indicates problems with radio unit.
The following problems cause the Radio Alarm to turn on:
− Rx signal level is lower the predefined value, - the
corresponding parameter is RxAlarmLev on the LCD or RxAlarmLevel using Telnet/ASCII console. The default value
for this parameter is -77 dBm;
− The humidity within the radio is too high (possibly ODU is
opened);
− Transmitter malfunction (TxOut=Error)
− RF Cable=Short – cable is faulty, RF Cable=Off – cable or
Radio is faulty;
− Tx and Rx syntheser loops are not locked (TxPLL=Error,
RxPLL=Error)
If not lit – operating properly (Rx=OK & TxOut=OK & Humidity=Low & RF Cable – OK & TxPLL=OK & RxPLL=OK); The RA LED will also switch on if the Radio loopback is active and/or if the transmitter power is switched off. The RA LED is updated one time per second.

LCD display and keypad provides most basic method to locally configure and monitor the local CFM terminal (IDU + ODU).
The LCD is constantly backlit and is able to display 2 lines of 16 symbols each line.
The LCD operates in two modes, Status display and Setup mode, please refer to Flow Chart 1, page 43.
Keypad consists of 4 buttons:
ENTER is used to confirm the choice of displayed item or entered data as
well as to switch from status display to setup mode.
CLEAR is used to cancel the choice or to move to previous menu level.
↑ ↓ Up/Down buttons are used:
- To switch between options for menu items displayed;
- To choose parameter to set up and to set its value.
4.2.1 “Status Display” Mode of the IDU LCD Management Interface
Once the IDU is powered up, it automatically enters “Status Display” mode, displaying two parameters at a time statically (use up/down buttons to scroll through parameters). These parameters are listed in the Table 7.
