4 Channel ASI to G.703 Multiplexer/De-Multiplexer
General Description
The MMM-4230 and MMX-4230 are part of a family of data transcoders for converting between the commonly
used MPEG2 Transport Stream formats for video distribution in the broadcast industry.
With the MMM-4230 up to four ASI and one RS422 data signals can be multiplexed together and converted into a
framed or unframed DS3 signal for transmission down a single 45 Mb/s G.703 line.
The MMX-4230 converts and demultiplexes the 45 Mb/s G.703 signal back into the original four ASI signals (at
their original rates) and the RS422 data signal.
An on board switch on the MMM-4230 sets the maximum data rates for each ASI input allowing the efficient use of
the available bandwidth and for protection against overuse of the bandwidth by the other channels. Total maximum
data rate up to 43.5 Mb/s is allowed. Temporary packet stuffing is used to automatically bring the rate up to
45 Mb/s.
Inputs are automatically equalised for lengths of up to 300m of Belden 8281 or equivalent cable.
RS422 9600 Baud uni-directional data may also be sent on the same link.
Front panel indication and relay alarm on the MMM-4230 transmitter shows if there is an input data rate violation.
Corresponding alarm on the MMX-4230 receiver shows a loss of G.703 input.
An optional Simple Network Management Protocol (SNMP) plug-in module is available for remote monitoring of
input and output status, control and alarm states.
The MMM-4230 and MMX-4230 are designed to fit IRT’s standard Eurocard frames as well as IRT’s 4000 series
frame for use with IRT’s SNMP system and may be used alongside any other of IRT’s analogue or digital
Eurocards.
Note: Also available in a 34 Mb/s G.703 version. See “Configuration - switch settings” section for configuration
table.
Standard features:
• Up to 4 ASI and 1 Data stream on one 45 Mb/s G.703 link
• Input rate stuffing to 45 Mb/s G.703 rate
• Selectable input maximum data rates
• Automatic Input equalisation up to 300m
• Suitable for Single Frequency Network (SFN) use
• Optional SNMP plug-in monitoring and control module
• Eurocard format

Switch settings
MMM-4230 45Mb version:
The MMM-4230 Multiplexer works in a channel protection mode. The necessity for protection arises if the data rate
of the inputs exceeds the maximum allowable for an MMM-4230 Transmitter (43.5Mb/s). Without protection all
used channels would suffer errors. With protection, the available data rate can be divided among the input channels
and if a channel tries to exceed its allocation only that channel is adversely affected.
A switch, SW1, on the MMM-4230 sets the maximum data rates for each ASI input.
For 204 byte packets the following allocation is possible.
Channel Data Rate Assignment

Variable Bandwidth – Channel Allocation Selection A:
For 188 byte packets the following allocation is possible –

40.2 - - -
26.8 13.4 - -

- - 26.8 13.4
- - - 40.2
13.4 - - 26.8
- 13.4 - 26.8
If only one channel is present then the total bandwidth is allocated to that channel.
If two channels are present and one exceeds a rate of 13.4 Mb/s then that channel will be assigned 26.8 Mb/s and
the other 13.4 Mb/s. However, input 1 has priority over inputs 2, 3, & 4, input 2 has priority over inputs 3 & 4, and
input 3 has priority over input 4. So even if, say, channel 2 has an input rate above 13.4 Mb/s and then input 1’s rate
also increases above 13.4 Mb/s, then input 1 will be assigned the bandwidth of 26.8 Mb/s whilst input 2’s will be
relegated to 13.4 Mb/s. Once a channel has been assigned a ba nd wid th o f 2 6. 8Mb/s it will retain the allocation until
either its input signal is removed, or until a channel with higher priority requires 26.8Mb/s allocation, or there are
any three channels connected.
If three channels are present they will each be assigned 13.4 Mb/s.
If four channels are present then channel 4 will not get any b andwidth.
The error concealment in the MMX-4230 will not allow an instantaneous change in channel allocation, so this
should be disabled when using the above option by installing link LK1.

Installation
Pre-installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling precautions
should be observed.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Power:
AC mains supply: Ensure that operating voltage of unit and local supply voltage match and that correct rating
fuse is installed for local supply.
DC supply: Ensure that the correct polarity is observed and that DC supply voltage is maintained within
the operating range specified.
Earthing:
The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure
that the frame is connected to earth for safety reasons. See frame manual for details.
Signal earth: For safety reasons a connection is made between signal earth and chassis earth. No attempt should be
made to break this connection.
Installation in frame or chassis:
See details in separate manual for selected frame type.
Signal Connections:
All ASI & G.703 inputs and outputs are by 75Ω BNC connectors.
Alarm output is via a two-pin 0.1” header. Alarm condition is when there is a short between these two pins. This
corresponds to either a loss of power or if there is an input data rate violation on the MMM-4230, or a loss of power
or a loss of G.703 input on the MMX-4230.
RS-422 data input and output connections are made via HE-14 8 pin double row connectors on both the MMM4230 and the MMX-4230.
SNMP:
When used in an IRT FRU400 Frame with a CDM400 SNMP Module fitted, the MMM-4320 and MMX-4320 can
be interrogated by an SNMP Network Management System and certain functions can also be remotely controlled.
For instance, the channel bandwidth assignment can be altered and any the RS errors that have occurred can be
read.
SNMP Traps on alarm states can be optionally sent.
The MIB (management information base) associated with these devices has the following OIDs (Object Identies):

SMU-4000 Installation
The SMU-4000 plug-in SNMP management controller module can only be fitted to IRT’s 4000 series modules that
are capable of being SNMP upgradeable. To determine whether a module is SNMP upgradeable, a square section
on the main PCB is silk screened and fitted with three multipin sockets – as shown below:
This is where the SMU-4000 plug-in SNMP management controller module is fitted. The three sets of multipins on
the underside of the SMU-4000 line up with the three sets of multipin sockets on the main PCB module. Align all
pins and then gently press the SMU-4000 all the way down into place.
If the SMU-4000 is not already programmed with the correct firmware to match the module that it is being plugged
into, it then needs to be programmed via the pins on the topside of the SMU-4000.
Note that installation will generally be done by IRT Electronics at the time of ordering.
Note also that an SMU-4000 will only be functionally operational when the main module that it is plugged into is
fitted into an IRT 4000 series frame fitted with a CDM-4000 SNMP agent and being interrogated by a suitable
Network Management System.

The RS-422 Standard
The RS-422 standard introduced in the early 1970s defines a balanced (or differential) data communications
interface using two separate wires for each signal. Due to the high noise immunity of the RS-422 standard, high
data speeds and long distances can be achieved.
The RS-422 specification allows reliable serial data communications for:
• Distances up to 1200 metres
• Data rates of up to 10 Mb/s
Only one line driver is allowed on a line, and up to ten line receivers can be driven by it. Figure 1.1 illustrates RS-
422.

SNMP
What Is It?
SNMP stands for Simple Network Management Protocol. It is an application layer protocol for managing IP
(Internet Protocol) based systems. SNMP enables system administrators to manage system performance, and to find
and solve system problems. SNMP runs over UDP (User Datagram Protocol), which in turn runs over IP.
Three types of SNMP exist: SNMP version 1 (SNMPv1), SNMP version 2 (SNMPv2) and SNMP version 3
(SNMPv3). It is not the intention here to discuss the differences between various versions, only to bring attention to
the fact that IRT Electronics modules, fitted with SNMP capability, use SNMPv1.
An SNMP managed network consists of three key components: Network Management Systems (NMS), agents, and
managed devices.
An NMS is the console through which the network administrator performs network management functions, such as
monitoring status (e.g. alarm states) and remote controlling, of a set of managed devices. One or more NMSs must
exist on any managed network. Generally the NMS is a computer running third party SNMP control software. There
are a number of third party SNMP software applications currently available on the market.
An NMS polls, or communicates with, an agent. An agent is a network management software module that resides in
a managed device. An agent has local knowledge of management information and translates that information into a
form compatible with SNMP. The agent, therefore, acts as an interface between the NMS and the managed devices.
The NMS sends a request message, and control commands for the managed devices, to the agent, which in turn
sends a response message, containing information about the managed devices, back to the NMS.
A managed device contains an SNMP agent and resides on a managed network. Managed devices collect and store
management information and make this information available to NMSs using SNMP.
Managed device agent variables are organised in a tree structure known as a Management Information Base (MIB).
Within the MIB are parameters pertaining to the managed device. An Object Identifier (OID) number within the
MIB defines the managed device type. This is a unique number specific to the model of managed device. Other
information relating to the device is also stored, information such as alarm states, controllable settings, etc. The MIB
tree is organised in such a way that there will be no two MIB files with conflicting placements.
Normally an NMS polls an agent for information relating to the MIB in a managed device to be sent back to the
NMS. When certain conditions are met within the MIB, such as major alarm conditions, for example, the agent
automatically sends what is known as a trap to the NMS without any prompting from the NMS. This allows
automatic notification of a predetermined event.

IRT Electronics currently employs SNMPv1 with its 4000 series frame. The frame acts as an agent when fitted with
a CDM-4000 module. This module has its own designated slot next to the power supply so as to not affect the
number of modules that the frame will take. Communication between the NMS, the frame and its loaded modules
are via this CDM-4000 module. Note that the NMS software is third party and not supplied by IRT Electronics.
Ethernet connection for SNMP operation is via an RJ45 connector on the rear of the frame, below the mains inlet.
Ethernet rate runs at either 10 baseT or 100 baseT.
Frame parameters, such as Name, Address and Location, are set via an RS232 interface, a D9 connector on the rear
of the frame below the mains inlet. A software terminal emulator, such as Tera Term or HyperTerminal, is used for
setting and reading the parameters of the frame.
IRT modules that are SNMP compatible need a plug-in SMU-4000 module with a program relevant to the module
that it is plugged into. Depending on the module, besides the module identification, parameters such as alarm states,
inputs and controls etc. are communicated to the CDM-4000 agent via a data bus on the rear of the frame. Thus the
CDM-4000 collects information on what is loaded within the frame, what positions they occupy, and their current
status for communication to the NMS when the NMS sends a request for information.
In the event of a major alarm from any of the SNMP compatible modules, or power supplies, a trap is automatically
sent by the CDM-4000 agent to the NMS without any prompting by the NMS. This alerts the operator to any fault
conditions that may exist that need immediate attention.

Maintenance & storage
Maintenance:
No regular maintenance is required.
Care however should be taken to ensure that all connectors are kept clean and free from contamination of any kind.
This is especially important in fibre optic equipment where cleanliness of optical connections is critical to
performance.
Storage:
If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed
plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be
included to deter corrosion.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Warranty & service
Equipment is covered by a limited warranty period of three years from date of first delivery unless contrary
conditions apply under a particular contract of supply. For situations when “No Fault Found” for repairs, a
minimum charge of 1 hour’s labour, at IRT’s current labour charge rate, will apply, whether the equipment is within
the warranty period or not.
Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on
components shall be extended by IRT only to the extent obtainable from the component supplier.
Equipment return:
Before arranging service, ensure that the fault is in the unit to be serviced and not in associated equipment. If
possible, confirm this by substitution.
Before returning equipment contact should be made with IRT or your local agent to determine whether the
equipment can be serviced in the field or should be returned for repair.
The equipment should be properly packed for return observing antistatic procedures.
The following information should accompany the unit to be returned:
1. A fault report should be included indicating the nature of the fault
2. The operating conditions under which the fault initially occurred.
3. Any additional information, which may be of assistance in fault location and remedy.
4. A contact name and telephone and fax numbers.
5. Details of payment method for items not covered by warranty.
6. Full return address.
7. For situations when “No Fault Found” for repairs, a minimum charge of 1 hour’s labour will apply,
whether the equipment is within the warranty period or not. Contact IRT for current hourly rate.
Please note that all freight charges are the responsibility of the customer.
The equipment should be returned to the agent who originally supplied the equipment or, where this is not
possible, to IRT direct as follows.
