2. Overview

2.1. Introduction

RC800-240B series fiber-optic multiplexers are ideal fiber-optic transmission devices for

point-to-point networks, medium-sized and small capacity networks, such as wireless

communication base stations, private communication networks, and switching networks.

The transmission capacity of RC800-240B is 8 E1 channels.

RC802-240B and RC804-240B fiber-optic multiplexers are the modular versions of

RC800-240B. They can be installed into RC004-16 16-slot chassis to be deployed at the

host site. The standalone multiplexers can be deployed at the remote site to work in pairs

with the ones at host site, and be managed by network management software.

2.2. Main Features

•Very large scale ASIC chips ensures low power consumption; 4-layer PCB ensures

high reliability

•Complete alarm indication that can display local and remote alarms simultaneously

•Alarm lock memory and E1 channel loop-back test capabilities implements convenient

operation and maintenance

•Provides 1 optical interface and 8 E1 channels and support cascading RC802-240BS

expansion sub-module to provide 16 E1 channels capacity.

•With modular design, it can be installed into any slot form 1st to 15th. If cascading

connection is required, it can be only installed into odd slots.

•One modular multiplexer shall correspond to one standalone multiplexer at the remote

site.

•Support SNMP management. It can be managed by the network management module

in the MPU slot of RC004-16 chassis. It also support out-of-band management of

standalone multiplexer at the remote site.

The shaded texts in the above table indicate the models that are covered by this manual.

Generally, it is required to add a suffix to the standalone RC801/803/805 series equipment

to indicate the type of power supply. For example, RC801-240B-S1/AC indicates AC 220V

power supply; RC801-240B-S1/DC indicates DC -48V power supply.

When interconnecting the fiber-optic multiplexers, it is suggested that follow the rules below.

The modular multiplexer shall be installed into host-site chassis.

4. How to use

4.1. Introduction of the Front Panel

The front panel includes the indications of E1 receiving signal loss alarms and optical

alarms. All the alarms are for the receiving link (signal input). The Line L indicates the

alarms generated at the local site and Line R at the remote site. The remote alarms are

Power (Green), ON when works properly

LOS1~8 E1 alarms (Red): ON when loss of signal in E1 channels

LOS optical alarm (Red): ON when loss of signal in optical link

LOF optical alarm (Red): ON when loss of frame in optical link

E-3 optical alarm (Red): flashing when severe BER exceeds 10-3

E-6 optical alarm (Yellow): flashing when BER exceeds 10-6

Fiber connector: DSC/PC for dual-strand fiber, TX for transmit and RX

for receive; SC/PC for single strand fiber

Mask fake alarm button:

Push-in, mask E1 fake alarms; push out, unmask.

sent through the optical link, so that they are accurate only when the optical receiving is

working in good condition.

4.2. DIP-switches Configuration

4.2.1. Dip-switches for E1 Interface Impedance

There are 8 groups of 4-bit dip-switches, SW1 to SW8. These switches

cannot be managed by network management software, so they must be

set manually.

Definition as shown below

1st 2nd 3rd 4th 1st 2nd 3rd 4th

ON ON ON OFF Or OFF OFF OFF ON

75Ωunbalanced signal effective 120Ωbalanced signal effective

As shown in figure above, the default status is set as “75Ωunbalanced signal BNC

interface effective”.

•When adopting 75 Ohm unbalanced signal, it is required to plug a DB37 to 8 CC3

coaxial adapter, which is of CC4B-8G type. This adapter can convert DB37 connector

to 8 CC3 coaxial connectors, for input and output of 4 E1 channels.

•When adopting 120 Ohm balanced signal, it is required to first set the dip-switches as

per the above tables. 37-pin connector shall be used to connect the twisted-pair cables

for DB37 connector. Please refer to Appendix A for details of sequence of twisted-pair

and cable making.

4.2.2. DIP-switch for Function Configuration

There is a 6-bit dip-switch SW10 on the PCB.

Note: Only two test method can be set: single E1 channel loop-back or all E1 channels

loop-back. When single E1 channel loop-back is testing, the other channels are working

normally without disturbance.

The network management software can send out the loop-back enable/disable command,

and they have high priority to the settings by hardware.

5. Installation and Test

5.1. Inspect after Opening

Please first check if the models and part numbers are in consistence, and also check if the

equipments are damaged.

5.2. Preparation before Installation

zCarefully read this manual

zPrepare all kinds of the cable. Ensure that they are not short-circuited. Refer to

Appendix A for cable making.

zEnsure RC004-16 is properly installed, and the chassis is well connected with the

ground.

zPrepare the BERT and optical power meter for test of line quality.

zChange the dip-switch setting on the bottom panel if 120 Ohm balanced signal interface

is required.

zSet up the fault-pass-through enabled if using the function.

zThis module does not support hot-swapping

5.3. Installation Procedure

5.3.1. Installing the Module into the Chassis

Insert the module into any service slot from 1st to 15th, with PWR indicator upside. The MPU

slot is particular for the network management module, thus cannot be inserted with service

modules.

Installing fiber-optic multiplexer in MPU slot will cause damage to the module itself or the

back panel of the chassis.

When combining with RC802-240BS expansion slave module, RC800-240B module will act

as the master. The master module shall be installed into odd-number slots, for example,

Slot 1, 3, 5… and 13. The slave module shall be installed into even-number slots, for

example, Slot 2, 4, 6… and 14. Slot 15 does not support combining.

5.3.2. Connecting Cables

zE1 port

The upside of RC004-16 chassis, corresponding to fiber-optic module, has 2 groups of

DB37 male interfaces. The upper one is for the 1st – 4th E1 channels, and the lower one for

the 5th -8th channels.

It is suggested that users use SYV75-2-2 coaxial cables to connect the BNC connector.

Users can connect a CC4B-8G adapter on DB37 male interface to connect CC3-K3 coaxial

cables.
