1. GENERAL INFORMATION

1.1. Introduction

The CODICO® RSW-7x00 Line of Redundancy Switches (R-Switches) are designed to fulfill
the need for automatic switching between multiple CODICO



devices. Redundancy
switching ensures uninterrupted transmission in a DVB broadcast system by transferring
the broadcast channel from one device to another in the event of a device failure. Figure
1-1 provides a general view of the RSW-7x00 Redundancy Switch.

Figure 1-1: RSW-7x00 Redundancy Switch Series - General View

The RSW-7X00 Line consists of the following Redundancy Switches:

1. CODICO® RSW-7000 R-Switch,

The RSW-7000 R-Switch is suitable for stand-alone redundancy solutions for 1+1 IRDs
(such as the CODICO® IRD-2600/2800).

2. CODICO® RSW-7200 R-Switch,

The CODICO® RSW-7200 R-Switch is suitable for transport stream (TS) redundancy
switching for Encoders (such as the CODICO

®

E-1x00 Encoder) or Multiplexers (such

1.3. Applications

The RSW-7x00 R-Switch Line of redundancy switches may be employed within a DVB
broadcast system for a dependable, uninterrupted signal flow. The following sub­paragraphs describe various typical applications for which the R-Switch can provide
redundancy control:

• IRD-7000 in a stand-alone 1+1 IRD redundancy application, see paragraph 1.3.1.

• IRD-7200 in a stand-alone 1+1 Encoder redundancy application, see paragraph 1.3.2.

• IRD-7200 in an NMS-4000 controlled Mux redundancy application, see paragraph

1.3.3.

• IRD-7200/R in a stand-alone 1+1 DSNG redundancy application, see paragraph 1.3.4.

• IRD-7200/O in a stand-alone 1+1 MCPC redundancy application, see paragraph 1.3.5.

1.3.1. Automatic 1+1 IRD Redundancy Application

The CODICO® RSW-7000 Redundancy Switch is a “Hot Switch Over”, without effecting the
service, featuring configurable switching time. Figure 1-2 illustrates an RSW-7000 R-
Switch controlling a 1+1 IRD Redundancy Transport Stream Output application.

At power-up, the R-Switch monitors the GPI Status from both IRDs, selecting the IRD-A
(default) as the Active device output.

Should a failure be detected in the active IRD-A, the RSW-7000 receives a failure status
report over the GPI Dry Contacts and sends a switching command (over GPI) to the IRDs.
The IRD-A outputs are disconnected, and the IRD-B device is selected as the Active
device. An alarm is activated that can be manually reset when the fault is corrected and
IRD-A is ready for operation. However, switching to IRD-A will be done only when a failure
is detected in the currently Active IRD (i.e., IRD-B).

The GPI command can be pre-set in the IRD for several alarm conditions. The user can
reconfigure the IRD, according to his specific/varying needs.

1.3.3. MCPC Distribution Redundancy Application

Figure 1-4 shows an MCPC Distribution N+1 redundancy application, controlled by a
remote NMS-4000 Network Management System.

Each one of the multiplexers receives N+1 channels from the encoders. Based on the
control from the NMS-4000, each one of the multiplexers selects N channels and
generates two identical ASI/G.703 multiplexed MCPC transport streams. The RSW-7200 R­Switch receives the two pairs of streams and selects one pair for distribution (over the
OUT1 output) and for local monitoring (over the OUT2 output).

The NMS-4000 monitors the status of each element in the system and controls the
operation of all elements:

• Selects and routes the video and audio inputs to the encoders, to provide N+1
Encoder redundancy, as well as controls the operation of each one of the Encoders,

• Controls the input selection and multiplexing process of each Multiplexer,

• Controls the input switching of the RSW-7200 R-Switch to provide 1+1 redundancy for

the Multiplexers.

encoders and selects which encoded and RF modulated output to provide to the Satellite
Up-Converter or HPA for satellite transmission. The R-Switch also switches the respective
RF output for local monitoring.

1.3.5. Optical MCPC Multiplexing Redundancy Application

Figure 1-6 displays a typical application of the RSW-7200/O R-Switch. Two Multiplexer
units (MUX1, Main, and MUX2, Redundancy) receive several transport streams and
generate two ASI level MCPC streams over fiber-optical cables. The resulting streams are
provided to the R-Switch, as follows:

• ASI1 (MAIN) optical stream is provided, via an IRD-2800 Integrated Receiver
Decoder, which checks the stream information, to the main input (IN-1) on the RSW­7200/O.

• ASI2 (BkUp) optical stream is provided directly to the backup input (IN-2) on the
switch.

The ASI level output of the R-Switch is provided over a fiber-optic cable to the ATM
Network.

The input switching operation of the RSW-7200/OPT is controlled over GPI lines received
as follows:

• The ASI1 (MAIN) input stream is switched to the output when both MUX1 and IRD­2800 generate “correct operation” GPI control signals (GPI1 OK).

• The ASI2 (BkUp) input stream is switched to the output when any of the MUX1 and
IRD-2800 does not generate “correct operation” GPI control signals (GPI1 NOT-OK)
and MUX2 generates the respective “correct operation” signal (GPI2 OK).

2. FUNCTIONAL DESCRIPTION

2.1. General

This section provides a functional description of the CODICO® RSW-7x00 family of
Redundancy Switches (R-Switches). This description includes a definition of options
available, a block-diagram level description of the switch architecture and description of
it’s the mechanical structure.

2.2. RSW-7x00 Configurations

The RSW-7x00 family of redundancy switches consists of the following options:

• RSW-7000 IRD Redundancy Switch

, which provides a GPI controlled, stand-alone

solution for 1+1 IRD redundancy.

• RSW-7200 IF TS Redundancy Switch

, which provides transport stream redundancy for
encoders and multiplexers, for high-bandwidth ASI or IF signals and Audio/Data/ASI
switching for stand-alone 1+1 encoders and for GPI controlled switching redundancy
for GPI enabled encoders, multiplexers, modulators and CIDs. The RSW-7200 can be
applied for redundancy control in an application controlled by Network Management
Systems (such as the CODICO® NMS-4000) or, as a stand-alone redundancy
application, controlled over GPI.

• RSW-7200/R RF TS Redundancy Switch

, which provides RF transport stream
redundancy (950 – 18,400 MHz RF modulated signals) for up-converter integrated
DSNG encoders and modulators. The RSW-7200 can be applied for redundancy control
in an application controlled by NMS-4000 or, as a stand-alone redundancy application,
controlled over GPI.

• RSW-7200/O Optical TS Redundancy Switch

, which provides optical transport stream
redundancy (Optical ASI or STM-1/OC3) for 1+1 encoders, multiplexers or modulators
redundancy applications. The RSW-7200 can be applied for redundancy control in an
application controlled by NMS-4000 or, as a stand-alone redundancy application,
controlled over GPI.

2.3. Architecture and Mode of Operation

In a stand-alone configuration, the R-Switch receives inputs from two devices, and
provides one output for broadcast. One device (device A by default) is set as “Active”, and
the second device (device B) is set as “Standby”. The R-Switch performs continual checks
on the status reports provided on the GPI Dry Contacts of both devices, determining their
state of operation over time. Upon signal failure or malfunction in device A, the R-Switch
changes device B to be the “Active” device with little or no interruption in the
transmission. Switching between the devices activates an alarm that can be manually de­activated when the failure is corrected.

Once the R-Switch has determined that the recovered device has stabilized, the status
indicator for device A will display OK instead of FAIL. Yet, returning device A to OK status
does not switches back device A to the status of “Active”. The switched status (B as
“Active” and A as “Standby”) is kept until a failure is detected in the currently active
device (B), and then the R-Switch switches again between the devices.

When the R-Switch is remotely controlled by the NMS-4000 Network Management System,
the NMS monitors and controls the operation of all elements in the system. Element status
is monitored by the NMS and the Redundancy switching is activated when required.

2.4. Structure

2.4.1. Housing

The RSW-7000 Switch is housed in a ruggedized industrial enclosure, 1 U by 19" (Rack
Mount). The unified enclosure allows for easy installation and integration into a new or
pre-existing system.

2.4.2. Front Panel

Each R-Switch in the RSW-7x00 Line of Redundancy Switch features controls for accessing
parameter menus displayed in the LCD window. A four–way touch pad controls cursor
movement in the LCD display. An entry is completed with the Enter and/or Escape touch
pads. Also installed is a Status Indicator LED, which flashes if a device fails or when
switching occurs. The Status Indicator LED remains ON when the system is functioning
properly. Figure 2-1 shows the front panel with its controls labeled.

Figure 2-1: RSW-7x00 R-Switch Line Front Panel

2.4.3. Rear Panel

Each model of the RSW-7x00 R-Switch Line features input and output interfaces, which
are specific to its application. The back panel of the R-Switch is configured for one of the
operation options – Electrical (ASI), RF or Optical (STM-1) transport stream. The
difference is in the input and output connector arrangement for the signals as shown in
Figure 2-2. The R-Switch can be powered either by AC or DC power supply.
