Introduction

1.3 Summary of Features

1.3.1 Overview

The MX8400 MPEG Video/Audio/Data Multiplexer is housed in a 2RU, 19-inch rack
mounted unit. It is designed to meet the needs of IP distribution infrastructures. It is
ideally suited to a wide range of multiplexing and re-multiplexing applications. These
include primary multiplexing in headends for Direct-to-Home (DTH) satellite
contribution and distribution systems. It can also provide the hub for applications in
cable and terrestrial television central headends.

1.3.2 Main Features

• Up to eight independent output transport streams, each capable of creating a

multi-program stream conforming to the MPEG-2 transport layer specification
(ISO/IEC 13818-1 MPEG-2 Systems). Each multiplexer can be configured
independently e.g. output data rates, PCR mode of operation.

Note: The MX8400/BAS provides a single multiplexer engine which produces a

single output transport stream, additional multiplexers are a licensable
feature (MX8400/SWO/MUX).

• The maximum output bit rate for a single multiplexer is 250 Mbps. The

resolution, to which the output rate of a transport stream can be set, by entering
a bit rate, is 1 bps.

• The output bit rate can be set exactly to any of the DVB-T modes.

• SFN adapter functionality is included to produce an output transport stream in

accordance to TS 101 191 V1.4.1.

Note: When operating in SFN mode, the output bit rate is calculated as described

in Annex H.

• The maximum aggregated output bit rate is 1 Gbps, shared across the transport

streams created.

• Each multiplexer supports Ericsson Reflex Statistical Multiplexing (see also

Section 1.3.3 for Remote Reflex). This enables connected Encoders to be
grouped together to share an overall group bit rate, allocating a percentage of
the total bit rate to each Encoder depending on the complexity of the encoded
content.

1-6

• Ericsson Reflex Statistical Multiplexing allows bandwidth harvesting to help

maintain quality targets. Any bit rates not being used by multiplexed components
are distributed across all component video services. Data rate sharing between
components allows a user-defined higher quality-target component to take
bandwidth from user-defined lower quality-target components.

• Internal time references are used to ensure the multiplexing process does not

affect time critical data.

2/1553-FGC 101 1014 Uen B

Introduction

• Multiplexer output transport streams can be created from any services or

components carried on any input transport stream. A single component can also
be used in multiple output transport streams. Each multiplexer engine receives
PSI/SI/PSIP table data via nCompass Control and manages the carousel
insertion of that data into the associated transport stream output.

• A maximum of 8192 PIDs for each multiplexer is supported.

• The dynamic PID tracking of incoming services is supported.

• PID filtering is supported to allow the removal of unwanted PIDs.

• PID remapping is supported to allow a component received on one PID to be

output on a different PID.

• Missing incoming PIDs can be detected and used to initiate appropriate alarms

to nCompass Control. Detected PIDs can also be excluded from the monitoring.

• The MX8400 can operate in both active and redundant modes. Synchronization

of MX8400 configurations is automatically maintained for redundant mode of
operation.

• The MX8400 provides Program Level Redundancy by sourcing any transport

streams missing from the primary network from the secondary network without
affecting any other active service. Refer to Annex E, Redundancy Modes for
further details.

• The MX8400 supports dual redundant 10/100 Ethernet interfaces for system

control and for CA data.

• The MX8400 supports a single fixed power supply(100-240 V AC)

• The MX8400 supports an Alarm relay connection.

1.3.2.1 Program Specific Information Generator (PSIG)

PSIG (described by ETSI TS 103 197, DVB: High-end Implementation of DVB
Simulcrypt) is supported by this release of the MX8400.

The PSI Generator (PSIG) is defined as the head-end process(es) responsible for
generating MPEG-2 PSI (Program Specific Information) tables.

Note: Please refer to Annex I PSIG Support for further information.

1.3.2.2 Program Clock Reference (PCR)

• Multiplexing non-time stamped components (e.g. DVB Subtitles or MHEG Data)

between incoming services is supported.

• The MX8400 supports mixing time stamped components that reference valid

PCR PIDs from different remultiplexed feeds/incoming services. This is normally
only supported with feeds that use a single PCR reference in the incoming
transport stream or single PCR based Encoder's inputs.

2/1553-FGC 101 1014 Uen B

1-7

Introduction

• Each multiplexer supports the use of re-multiplexed PCRs (that is all multiplexed

services maintain their original program clock reference) or a single common
PCR (all incoming services are time adjusted to reference an internally
generated PCR).

Note: When operating in single PCR mode all contributing services must be

locked to a single common clock reference e.g. studio clock (HSYNC IN).

• Release 5 of the MX8400 provides the capability, under nCC control, to allow

the remultiplexing of transport streams without reading, analyzing or processing
the PCR. This means the user can specify that an incoming transport stream
uses a raw bit rate measurement (i.e. ignore the PCR values in the transport
stream).

1.3.2.3 Frequency Synchronization

• The main MX8400 system reference clock is an internal 27 MHz voltage

controlled oscillator. It can be locked to an externally sourced clock reference,
via the HYSNC input or GPS input. It can, also, be locked to the high-precision
on-board clock if no external source is available.

• Dual HSYNC clock inputs support the option of locking an internal frequency

reference to an external studio clock. The external clock reference is
configurable to accept 625 or 525 line video standards.

• Dual HYSNC clock output.

1.3.2.4 Table Generation

• The MX8400 can generate and insert the DVB Time and Date Table.

• The MX8400 can insert the DVB Time Offset Table. (This requires the use of

third-party equipment.)

• The MX8400 can insert the PSIP System Time Table. (This will require the use

of third-party equipment.)

1.3.2.5 TS IP Summary of Features

• Four independent

2

GbE transport stream data ports are provided. Each port

supports both RTP and UDP formatted packets.

• GbE interfaces support IP packet jitter removal

1.3.2.6 ASI Input/Output Summary of Features

• Four ASI outputs are provided. These support 188 and 204 byte transport

stream packets and are able to operate in byte and single packet burst mode.

• Two ASI inputs are provided. These support 188 and 204 byte transport stream

packets and are able to operate in byte and single packet burst mode.

2

Each port has its own MAC address.

1-8

2/1553-FGC 101 1014 Uen B

Introduction

• Indicators at the rear panel of the unit indicate the status of the ASI input and

outputs. These are described in Section 2.7.5 of Chapter 2, Installing and
Powering Up.

1.3.2.7 Dual PSU

The MX8400 Multiplexer is now available with dual hot-swap PSUs. See Chapter 5
for more information relating to the PSU.

Note: This is a new product and not an upgrade path.

1.3.3 Remote Reflex

1.3.3.1 Statistical Multiplexing

Statistical multiplexing delivers the efficient use of bandwidth whilst maintaining
picture quality. It makes use of the variable bit rate nature of video compression and
the improbability that all channels will peak in bit- rate demand simultaneously.

Grouping encoders together and allowing the group to share an aggregate pool of
bit rate enables the head-end system to provide either a better picture quality than
constant bit rate operation, or to maintain constant quality while adding more
channels into the multiplex.

Reflex is Ericsson's implementation of statistical multiplexing and is associated with
a multiplexer being co-sited with the encoder-sourced services. Remote Reflex is
used when services are sourced from encoders which are sited remotely from the
multiplexer.

1.3.3.2 Remote Statistical Multiplexing

With the introduction of IP-based connectivity between the MX8400 multiplexer and
the new encoder ranges, the Reflex technology has been extended to support
encoders located at remote locations over Wide Area Network to offer additional
benefits of further improved picture quality, higher efficiency and reduced capital
expenditure.

Up to 64 services for each output transport stream can be supported using Remote
Reflex. However, the total number of outgoing services across all transport streams
is limited to 400.

Remote Statistical Multiplexing is only available over IP and is not available for ASI
connections.

1.3.3.3 Reflex Operation

Remote Reflex allows statistical multiplexing of encoders located at a distance from
the MX8400, providing that the largest network latency between an encoder and the
MX8400 is no greater than 400 milliseconds.

2/1553-FGC 101 1014 Uen B

1-9

Introduction

A system dependant delay constant is defined at the system configuration stage.
The MX8400 calculates the latency for individual Encoders and sets buffers
appropriately to ensure all Encoders within the system experience the same network
delay. This is achieved by ensuring the delay an Encoder service experiences is
equal to the predefined system delay constant.
An Encoder at a remote site will experience a larger delay in the network and is
therefore delayed less within the MX8400 input than an local based Encoder service
which is part of that the same Remote Reflex group.

Modes 0 and 1 are supported as standard on this release. The
scrambling mechanism, as defined in the DVB-CSA specification, is applied at
the Transport level only. This is configured using nCompass Control.

- Mode 0: No scrambling.

- Mode 1: All components are scrambled by a fixed Control Word (CW),

derived from a clear Session Word (SW). The MX8400 accepts the session
word is via an XML control interface. Any invalid session words will be
rejected (it must be a 12 character hex string).

• Individual transport streams can be scrambled simultaneously with either

DVB CA or BISS but not individual components. The MX8400 will only support
one scrambling method on a single PID.

1.3.5 Single Frequency Networks Functionality

The MX8400 Multiplexer supports up to eight output transport streams with SFN

Installing and Powering Up

2.3.7.2 Temperature Monitoring

Unit Temperature Monitoring

The equipment has an over-temperature (>50°C) alarm which is used to drive the
fail indication (see below).

Power Supply Unit Temperature Monitoring

A temperature warning circuitry monitors the PSU case temperature. The monitor
circuit output signal changes from high to low impedance, when the case
temperature exceeds the upper threshold level, and changes back to high
impedance, when case temperature falls below the lower threshold level, which is
85 °C ± 5 °C.

If the PSU case exceeds 105 °C, the PSU shuts down. It will resume operation
automatically, once the case temperature falls below 105 °C.

Fail Indication

The alarm illuminates the front panel FAIL indicator and drives a Fail relay which is
accessed via a rear panel connector.

When the equipment is installed in a redundancy configuration, the alarm can be
used by nCompass Control to trigger a change-over to a standby MX8400
Multiplexer. The relay is non-latching and will revert to its normal state when the fail
condition is corrected.

2.8.1 Overview

2.8.1.1 Port Configurations

There are four dedicated IP/GbE interface ports using RJ-45
connectors. Using nCompass Control, the MX8400 IP/GbE interface
ports can be configured as detailed in Table 2.3.

Notes: All ports support IP management data (e.g. Ping/ARP) independent of their

data path configuration.

Two Small Form Pluggable (SFP) connectors can be supplied to substitute

for Ethernet Data ports 1 and 2. When these are used, Ethernet Data ports
1 and 2 are disabled.

2.15 HSYNC Clock Reference

2.15.1 Overview

2.15.1.1 HSYNC IN (2 off)

The HSYNC IN analogue input enables external video clock
reference support.

An internal 27 MHz clock, when configured by nCompass Control, is
frequency-locked to the studio clock using one or other of the HSYNC
IN inputs. If the external studio reference fails, the MX8400 continues
to operate holding a close frequency approximation to the lost
external reference.

The two HSYNC signal inputs are used to support redundancy. If configured, the
MX8400 switches to the secondary HSYNC input when the primary HSYNC input is
missing or off frequency. The action of switching to the secondary input does not
impact on the output services. The MX8400 switches back to the primary input when
reconfigured by the user or if the secondary input fails.

2.16 Upgrading the MX8400 Multiplexer

The MX8400 Multiplexer software can be upgraded without removing the MX8400
from its installation. Version numbers of the codes stored in the MX8400 Multiplexer
are reported to nCompass Control.

Multiplexer functionality can be extended by the use of purchasable options. Please
refer to Chapter 3, Options and Upgrade.

2.17 Powering Up/Down

2.17.1 Before Powering Up

Before powering-up the MX8400 Multiplexer, check the following:

1. The equipment has been installed in a suitable location.

2. The power supply has been checked and a good earth provided.

3. The correct fuse type and rating has been fitted to both the equipment and the
AC supply cable (if appropriate).

2.17.2 Powering Up

If the enclosure fans are not rotating, isolate the equipment immediately from the
supply, then contact the manufacturer using the Customer Services information
given in the Preliminary Pages of this guide.

An automatic shutdown will occur if the Power Supply Unit overheats.

Installing and Powering Up

To power up the MX8400, perform the following:

1. Switch on the local AC supply (or supplies if dual PSUs are fitted) to apply power
to the equipment. The MX8400 executes a series of power up initialization and
self test routines.

2. Check that all cooling fans are rotating. If they are not, switch off the equipment
immediately.

3. Check the Alarm indicator is on during initialization and extinguishes after a
successful boot which is about 30 seconds.

2.17.3 Power up Self Test

On power up, the MX8400 runs through a boot sequence that includes a series of
self tests that can take between five and ten seconds to complete. During the test,
the red Alarm indicator at the front panel is lit.

If the test result is a PASS, the unit is now ready to receive its configuration from
nCompass Control. This is indicated by the Alarm indicator extinguishing.

If the test result is a FAIL, the MX8400 Multiplexer remains in the self test mode with
the inputs disabled. The Fail relay is set, and the Alarm indicator at the front panel
remains lit.

On successful completion of the self tests, the MX8400 moves on to the start-up
sequence.

2.17.4 Start up Sequence

The MX8400 Multiplexer runs through an initialization sequence after successful
completion of the power up self tests. No configuration parameters are stored after

3.3 RJ-45 Ethernet Option Card with ProMPEG FEC (MX8400/HWO/PROFEC)

3.3.1 Overview

3.3.1.1 Introduction

The IP I/O option card occupies a single option slot and is fitted with four RJ-45
connectors with speed, link and activity indicators, The ProMPEG Forward Error
Correction (FEC) scheme is designed to recover lost or corrupted packets.

It is possible to fit eight IP input / output option cards in the chassis and to run all
Ethernet interfaces at full speed input concurrently. However only 1 Gbps of traffic
is allowable on the backplane.

By default port 1 is the primary port, port 2 is the secondary port. Autonomous is the
default input mode, mirrored is the default output mode

This option card supports all of the redundancy modes as the main card but the
operations are only achievable across ports on the same physical card (between the
ports on a single option card or between the ports on the main board). Redundancy
is detailed in Annex E, Redundancy Modes.

3.5 GPS Interface Module (MX8400/HWO/GPS)

3.5.1 Overview

3.5.1.1 Functional Description

The addition of SFN adapter functionality within the MX8400 as part of Release

3.0.0 allows SFN headend architectures to be designed around the MX8400 without
the need for third-party SFN adapters. The main function of the SFN adapter is to
produce an output transport stream which is in accordance to TS 101 191 V1.4.1.
Please refer to Annex H, Setting up the SFN Functionality for details of the SFN
Adapter.

The SFN adapter provides the information within the outgoing transport stream to
allow all modulators operating within the same SFN network to broadcast in a
synchronised manner. The synchronisation is achieved by frequency locking the
SFN adapter and Modulators to a GPS 10 MHz reference clock derived from GPS.
The GPS Interface Module (MX8400/HWO/GPS) provides this signal to the unit.

4.2 About nCompass Control

Ericsson nCompass Control is a service-oriented system manager for control of
DVB-compliant equipment. It is a Microsoft Windows XP based client server
application that provides configuration, monitoring and redundancy. Ericsson
nCompass Control clients provide the operator with a graphical user interface (GUI)
to the server's on-line functionality, as well as off-line set up and configuration
options.

nCompass Control provides control of all broadcasting equipment for satellite,
terrestrial and cable headends. It integrates Ericson’s MPEG-2/MPEG-4/DVB­compliant equipment such as Receivers, Decoders, Descramblers, Encoders,
Multiplexers, and Modulators, with third-party ECM/EMM generators, and switches
into one manageable digital TV broadcasting system.

nCompass Control comprises the following applications:

• nCompass Equipment Set up - used to set up the system and to add, edit and

delete devices in the Set up database.

• nCompass Profile Manager - used to schedule events, see Profile Manager.

• nCompass Equipment Status - used to view the status of the equipment.

• Reflex Activity Viewer - this is a separate application used specifically for

monitoring Encode bit rate.

The Equipment Status GUI displays the health condition of the equipment using a
schematic of the system as defined in the Equipment Set up GUI.

The nCompass Status Monitoring application provides graphical monitoring of
system status and alarm logging. Real-time activity is monitored via the Activity
Viewer.

4-4

All active (current) alarms are displayed with their corresponding colour-coded alarm
level. It is also possible to display the current configuration applied to the system,
showing the networks, transport streams, services, and components.

The schematic view is fully scalable, using zoom and pan functions, enabling
navigation of large networks and multiple views.

2/1553-FGC 101 1014 Uen B

Operating the Multiplexer using nCompass Control

The nCompass Control is required to configure the MX8400. Monitoring can be
done using nCompass Equipment Status.

4.3 Connecting the MX8400 Multiplexer

To test connectivity to the MX8400 Multiplexer (once the IP address has been set),
connect it to a PC using one of the Control ports, and use the PING command.
Once IP connectivity has been established all other configuration is achieved using
nCompass Control.

1. Run nCompass Control's Equipment Setup GUI

2. Open a new map

3. Right click and select Add device -> Mux

4. Enter the MX8400's IP address and click "Get Static Parameters"

5. This will allow you to configure all the static parameters on the unit (see Annex C

for the use of static parameters)

6. The dynamic parameters are all configured using nCompass Control's Profile

Manager

For further details, refer to the nCompass Control manual.

4.4 Configuring the MX8400 Multiplexer

4.4.1 Definition

In the context of this Reference Guide, Operating the Equipment Remotely refers to
the MX8400 Multiplexer in conjunction with nCompass Control. This is where the
customer operates a system requiring scheduled changes to the bit rates and
configurations.

Using this mode of operation, system and associated parameters are constructed in
the nCompass Control and downloaded to the MX8400 on completion or to a timed
schedule.

4.4.2 nCompass Control Functions

nCompass Control provides a centralized control function for the Ericsson
multichannel range of equipment. In particular, it provides the following facilities:

• Configuration of Encoders, Modulators, Routers and Multiplexers over an

Ethernet link.

2/1553-FGC 101 1014 Uen B

4-5

Operating the Multiplexer using nCompass Control

• Generation of MPEG-2/MPEG-4 Program Specific Information (PSI)1 including

Program Association Table (PAT), Program Map Table (PMT) and Conditional
Access Table (CAT).

• Generation of DVB Service Information (SI).

• Status monitoring of Encoders, Multiplexers.and any other supported equipment

switches.

• Redundancy control for systems with spare Encoders, Multiplexers and

Modulators.

• Configuration and PSI data input either locally, on the nCompass Control user

interface, or via a remote interface.

These functions are described in the appropriate nCompass Control documentation.

4.5 MX8400 Multiplexer Modes of Operation

4.5.1 Introduction

There are two types of multiplexing available with the Ericsson range of equipment.

In the simplest mode of operation, called conventional multiplexing, nCompass
Control allocates a fixed bit rate to each Encoder. The Operator can use the display
from nCompass Control to manually alter an Encoder’s bit rate.

The second system, implemented using Ericsson’s Reflex software, allocates a
group bit rate to a set of Encoders. The MX8400 then apportions the bit rate to the
Encoders according to the requirements of the picture encoding process.

4.5.2 Summary of Multiplexing Modes

4.5.2.1 Conventional Multiplexing

The major features of conventional multiplexing are:

• Uses constant bit rate Encoder.

• Bit rate determined by Operator.

• Bandwidth utilization maximized by the Operator.

• Non-optimum usage of channel capacity in systems with varying picture content.

• Use of fixed bit rate leads to variable picture quality.

(DVB) Systems”.

2/1553-FGC 101 1014 Uen B

Operating the Multiplexer using nCompass Control

4.5.2.2 Statistical Multiplexing

The major features of statistical multiplexing are:

• Uses variable bit rate Encoders.

• Employs real-time bit rate management.

• Continuously reallocates bandwidth between Encoders (within a set group).

• Maintains a target picture quality on all channels.

4.5.3 Conventional Multiplexing

4.5.3.1 Limitations of Fixed Bit rate Encoding

In the conventional multiplexing mode, the Encoder bit rate is allocated at the start
of a scheduled period. Each individual Encoder is unable to respond dynamically to
the complexity or speed of change of the picture. Because of this, the picture quality
decreases and the decoded output contains more encoding distortions as the
material becomes more demanding.

4.5.3.2 Allocation of Bit rates

The Operator must take into account the likely or known peaks in picture complexity
to allocate a bit rate which would avoid compression artefacts. The fixed bit rate is,
therefore, set at the level required to satisfy peak demands. This leads to the non­optimal use of the channel capacity.

4.5.4 Statistical Multiplexing (Reflex)

4.5.4.1 Advantages of Statistical Multiplexing

In the statistical multiplexing (Reflex) mode, a group bit rate is dynamically allocated
in real-time between a set of Encoders (usually four or more).

The Operator assigns a relative quality to each Encoder in a set. This is a measure
of the picture quality expected from each Encoder. A preference can be assigned to
a channel by allocating a higher than average relative quality to the appropriate
Encoder. Excess bit rate from one Encoder can be reallocated to another to keep it
at its picture quality target.

4.5.4.2 Role of the MX8400 Multiplexer in Statistical Multiplexing

The MX8400 requests picture quality information in turn from each Encoder in a set.
Using this information, it then calculates any changes to the apportionment of the
group bit rate to ensure the target relative picture quality for each Encoder is
maintained.

2/1553-FGC 101 1014 Uen B

4-7

Operating the Multiplexer using nCompass Control

The system responds to variations in the criticality of the source pictures so that the
MX8400 is able to maintain overall picture quality targets by readjusting bit rate
allocations.

4.5.4.3 Features of the Reflex Software

The major features of the Reflex software are:

• Seamless bit rate change from 700 kbps

fields, period (40 ms for PAL-I and 33 ms for NTSC-M).

• Each Encoder can be given a weighting factor.

• Once configured, the Reflex system requires no further Operator involvement.

• Relies on the statistical distribution of bit rate demand across programme

sources.

• Exploits the likelihood that peaks in demand are infrequent on any single

channel.

4.5.5 Using Statistical Multiplexing

4.5.5.1 Introduction

The following information explains the use of statistical multiplexing. The parameters
are entered via nCompass Control for use by the MX8400 Multiplexer.

4.5.5.2 Allocation of Bit rates

A Reflex group (set of Encoders) is allocated a total bit rate which creates a pool
from which the Encoders can draw. The following points should be noted in setting
up a group:

2

to 10 Mbps in a single frame, two

• The number of Encoders in the group.

• The resolution each group is set to.

• The types of material being encoded by each Encoder.

• The noise levels present in the source material.

• The required picture quality.

Table 4.5 can be used as a guideline.

The figures shown can vary depending on encoding type and delay mode.

The more Encoders there are in a group, the more potential there is to reduce the
group bit rate, although this may have to be modified in the light of any
remultiplexing further downstream.

4.5.5.3 Weighting Factor

A weighting factor can be assigned to each Encoder in a group to create a bias to
that channel. In the example above, Encoder 1 can be given priority thus ensuring
higher picture quality in the event of a conflict. If no bias is required, the weighting
factor should be set to the same value.

4.5.5.4 Minimum and Maximum Bit rates

4.5.5.4.1 Minimum Bit rate

Configuring the minimum bit rate too high reduces the available bit rate for other
Components in the group.

4.5.5.4.2 Maximum Bit rate

Configuring the maximum bit rate too low downgrades the video quality.

A video component may be excessively noisy. Under these conditions, the
associated Encoder may attempt to command large bit rates in the group and
compromise the picture quality on other video components. To avoid this situation,
set the maximum bit rate according to Table 4.7.

4.5.5.5 Group Performance

4.5.5.5.1 Defining the Term

The Group Performance provides a performance check on the statistical
multiplexing process. In general, the bigger the Encoder group the more scope for a
better performance figure. A group containing reasonable weighting factors
compared to the group bit rate will also have a better group performance figure.

4.5.5.5.2 Monitoring Group Performance

Group Performance can be monitored on the Activity Viewer via nCompass Control
user interface. The Reflex performance screen shows bit rate and quality plots, and
the group performance meter.

4.5.5.6 Grouping of Encoders by Picture Material

If possible, create a group of Encoders carrying a mix of programme types. This is
likely to create the conditions required to achieve an optimal group.

4-10

2/1553-FGC 101 1014 Uen B

Operating the Multiplexer using nCompass Control

It is not advisable to group together all sports or news material. However, in most
situations, the grouping of different programme types will not greatly affect the
overall performance.

4.5.5.7 Grouping to Allow for Remultiplexing

The reason the Reflex software has the capability to create multiple statistical
multiplexing groups is to allow for remultiplexing of programmes further downstream.
If all Encoder bitstreams were in a single group, it could be difficult to remultiplex a
sub-group further down the transmission chain.

4.5.5.8 Protecting Channels

It is possible to set up the weighting and maximum/minimum bit rates to ensure a
quality of service on one or more Encoders. An experienced Operator would be able
to protect certain chosen channels by careful choice of these parameters thus
restraining the total bit rate demanded by others in the group.

Table 4.8 shows the situation where channels 1 and 2 are protected.

In the above configuration, the maximum bit rate Encoders 3 and 4 can demand
between them is 10 Mbps. This leaves a guaranteed minimum bit rate of 5 Mbps
available to Encoders 1 and 2.

4.6 Data and Service Bandwidth

The bitstreams arriving from the Encoders include transport overheads. There are
also additional data overheads associated with the multiplexing process, PSI, PSIP,
SI, PCR and forward error correction (FEC) information. The actual net data rate is a
proportion of the gross transport bitstream. The ratio is system configuration
dependent.

4.8 Setup ASI Monitoring for Each Output Transport Stream

4.8.1 Overview

Each MX8400 Multiplexer has four ASI output ports which, for example, can be used
to simultaneously monitor up to four IP transport streams. It is possible to configure
an ASI output as a monitoring output to enable the user to verify the IP output. The
block diagram in Figure 4.3 has the same configuration as Figure 4.1 to illustrate the
process.

4.8.2.3 Set up a Secondary Output for the Transport Stream

The next step is to set up a secondary output for the transport stream. This cannot
go over the same physical port. In this configuration, the secondary output is
required to provide the feed to the Monitoring device. This has the same content as
that supplied as the primary output.

If required, more than one secondary output can be added for a single transport
stream.

4.9 Set up PSI/SI Remultiplexing

4.9.1 Overview

This configuration removes user selected PSI/SI generated by nCompass Control
and the MX8400 Multiplexer and allows the operator to create a Private Data stream
with PSI/SI from an incoming transport stream

Only outputs that can be
routed should populate
this list.

4.9.3 Adding the Private Data Stream

A Private Data stream is a way of remultiplexing an incoming PID. The PID exists at
the transport stream level then it is not automatically referenced in the PMT. The
process for adding a private data stream is described in Table 4.14.

4.10 Set up Single Program Clock Reference (Remultiplexed Input)

4.10.1 Incoming Transport Stream

Unless the incoming transport stream has exactly the same 27 MHz reference as
the local Multiplexer, Single-PCR operation is only supported for Ericsson Encoder­based services. When operating in this mode, the Encoders and Multiplexer/s must
be frequency locked to the same studio clock reference source.

4.10.2 Mixed PCR System

The PCR PIDs of the remote input can be remultiplexed (if it has a separate PCR)
or, if the input is a component, it will be removed with its embedded PCR. This is
termed a Mixed PCR system.

4.11 Clone a TS in the Clear

This configuration produces a cloned output in addition to the main scrambled
output. This could be used for local monitoring purposes.

The process has three steps:

1. Add an output device to the Physical Map

2. Configure the Multiplexer to produce the Clear stream

3. Connect the Multiplexer to the Output device.

Preventive Maintenance and Fault-finding

5.1 Introduction

This chapter provides the instructions for routine inspection, cleaning and
maintenance of the equipment that should be performed by an operator. There are
also some basic fault-finding procedures to follow in the event of a suspected
MX8400 Multiplexer failure.

5.2 Routine Checks

5.2.1 Cooling Fans

No routine checks are associated with this equipment other than to ensure that the
equipment is correctly cooled. This equipment must not be operated unless all
equipment fans are working, therefore, periodically check the operation of all fans.

Failure to ensure a free flow of air around the unit may cause overheating. This
condition may be detected by a temperature sensor In the MX8400 but will not
automatically shut off the equipment. Only the PSU has an automatic shut-off
feature which shuts it down if its case temperature exceeds105 °C.

5.2.2 Cleaning

Unplug the equipment from the AC supply before cleaning. Do not use liquid or
aerosol cleaners. Only the exterior of the case should be cleaned using a damp
cloth.

5.3 Servicing

5.3.1 Damage Requiring Service

Caution!

Warning!

Do not attempt to service this product as opening or removing covers may expose
dangerous voltages or other hazards. Only suitably trained and experienced service
engineers are permitted to service this equipment.

2/1553-FGC 101 1014 Uen B

5-3

Preventive Maintenance and Fault-finding

Do not attempt to service this product as opening or removing covers may expose
dangerous voltages or other hazards. Refer all servicing to qualified service
personnel who have been appointed or authorized by Ericsson.

Isolate the Multiplexer from the AC power after the following conditions:

1. When the AC power cord or plug is damaged.

2. When a new fuse blows within a short time of replacement or when there is
reason to suspect a faulty power supply.

3. When liquid has been spilled, or objects have fallen into the product; or when
the product has been exposed to rain or water.

4. When the product does not operate normally after following the operating
instructions. Adjust only those controls that are covered by the operating
instructions; improper adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to restore the product to its
normal operation.

5. When the product has been dropped or the case has been damaged.

6. When the product exhibits a distinct change in performance.

5.3.2 Replacement Parts

When replacement parts are required, ensure the service technician has only used
parts specified by the manufacturer or have the same characteristics as the original
part. Unauthorized substitutions may result in fire, electric shock or other hazards.

5.3.3 Checks on Completion of Servicing

Upon completion of any service or repairs to this product, ask the service technician
to perform safety checks to determine that the product is in a safe operating
condition. Carry out any performance and EMC checks that may be required.

5.4 Maintenance and Support Services

5.4.1 Warranty

All Ericsson products and systems are designed and built to the highest standards
and are covered under a comprehensive 12 month warranty.

information is given in the preliminary pages of this Reference Guide.

5.5 Fault-finding

5.5.1 Unit Faults

The MX8400 Multiplexer monitors and report errors on all major items (such as fans,
power supplies and option cards) and monitors its internal temperature.

All faults are logged and not lost during a power failure. All internal logs are stamped
with the time and date.

Any abnormal condition that does not impact directly on the MX8400’s operation is
flagged as a warning. This includes conditions like single fan failure or switched to
redundant input where the unit will continue to operate but should be investigated.

It is possible to set each alarm condition to be ignored, raised as a warning or an
alarm. All alarms and warnings are made available to the user via the nCompass
Control system.

A list of reported unit faults is shown in Table 5.1.
