System description

The block diagram for the MS430580M is given in Figure 1. The MS430580M is a bi­directional device that offers twice the same media convertion/regeneration
functionnality

• From one interface input signal (Line 1 or Line 2) to one interface output signal

(Line 2 or Line 1).

The MS430580M includes also several sections composed of

• Controller block, providing interfacing to the MS module series chassis controller

board hosting the SNMP Agent.

• Power supplies: generates different internal power supplies from the -48V of the

MICROSENS chassis backplane

Media converter / Regeneration description

The received signal is first converted from optical signal to electrical signal through the
SFP interface. Then the electrical signal is converted to an optical signal through the
second SFP interface.
These two conversions (optical to electrical and then electrical to optical) perform a
retiming, reshaping and retransmission of the optical signal from the Line 1 (or Line 2)
input to the Line 2 (or Line 1) output.
Upon the SFP type used on Line 1 and Line 2, it is possible to perform, together with
the signal regeneration, a media convertion (850nm to 1310nm, CWDM to DWDM, etc).

The following alarms are provided to the controller block:
Line 1 and Line 2 Loss of incoming Signal
Line 1 and Line 2 Laser Shutdown
The following measures are provided to the controller block:

• SFP temperature in °C

• SFP voltage in V

• SFP receive power in dBm

• SFP transmit power in dBm

• SFP laser pump current (bias) in mA

Clock Generation Unit

The Clock Generation Unit provides the reference clock to the Line 1 and Line 2 optical
interfaces according to the parameter given by the Controller Block. The reference
clock is internal to the MS430580M and has a stability of +/- 50 ppm. The Clock

Generation Unit can provide a reference clock to supLine 1 bitrate from 125 Mb/s up to

2.67 Gb/s. Therefore the MS430580M can support the following protocols:

Protocol Bitrate

Fast Ethernet 125 Mb/s

OC-3/STM1 155.52 Mb/s

OC-3/STM1-FEC 166.62 Mb/s

OC-12/STM4 622.08 Mb/s

OC-12/STM4-FEC 666.51 Mb/s

1GFC 1.0625 Gb/s

GbE 1.25 Gb/s

2GFC 2.125 Gb/s

OC48/STM16 2.448 Gb/s

OC48/STM16-FEC 2.666 Mb/s

Controller Block

The controller block is composed of a microprocessor associated with Flash and RAM
memories. The controller block collects information from different functional blocks
and configures the HW according to a configuration file received. The raw information
(alarms, monitoring, inventory) generated by the HW are processed by the
microprocessor and delivered to the MICROSENS chassis Management Board as high
level consolidated data.

Interface Specifications

Line 1 and Line 2 interfaces are provided by SFP transceivers. The optical characteristics
are therefore given in the data sheet of the SFPs plugged into the MS430580M module.

How to modify the Configuration

The following procedure outlines how to modify any configuration. This can be
performed at any time, keeping in mind that the cold reset will affect the traffic.

Note
This is module type dependant. Consu lt the table in the Description section
to determine if it is applicable or not. The following modifications may be
achieved by using control objects in:
...\microsens\modulems430580m\ms430580mcontrolsWrite\
However modifications made in this way are lost following a reset.

MICROSENS GmbH & Co. KG - Küferstraße 16 - 59067 Hamm - Tel. [phone] - Fax [phone] - www.microsens.com

Media Converter/Signal Repeater page 7/29

The Line and Client configuration modification can be performed at the same time and
applied at the same time with one reset. Traffic implications will depend on your choice
of reset.

Procedure

• Ensure that the correct module is selected for management. Consult the object:

− mgnt2GigmSelectedBoard

Location:…\microsens\mgnt2\mgnt2SNMPAgentData\
mgnt2ModulesManagement\

• Change if necessary.

• Determine a value corresponding to the configuration profile you require.

• Perform an SNMP SET to write the value corresponding to the required

configuration profile into the SNMP agent.

• Perform a SET to “on” the object:

− ms430580mCfgWriteConfiguration

Location: ...\microsens\modulems430580m\ms430580mConfig\
This will load the new configuration from the SNMP agent to the modules RAM.

• Transfer the new configuration into the module using the object:

− ms430580mCtrlConfFlash

Location:
...\microsens\modulems430580m\ms430580mcontrolsWrite\ms430580mCtrlOther\
ms430580mCtrlsynth0\

• Restart the module using a cold reset or by powering down/up to apply the

configuration modification. Reset information can be found in the Software
management section.

Note
At that point, configuration 2 becomes the default configuration of the MS
module.
