The thin glass fiber core at the center of the cable is fragile when exposed by the removal of cladding and buffer material. It easily fragments into glass splinters. Using tweezers, place splinters immediately in a sealed waste container and dispose of them safely in accordance with local regulations.
Introduction
This equipment can be provided with an infrared laser that transmits intensity­modulated light and emits invisible laser radiation.
Warning: Radiation
Do not apply power to the equipment if the fiber is unmated or unterminated. Do not stare into an unmated fiber or at any mirror-like surface that could reflect
light that is emitted from an unterminated fiber.
Do not view an activated fiber with optical instruments (e.g., eye loupes,
magnifiers, microscopes).
Use safety-approved optical fiber cable to maintain compliance with applicable
laser safety requirements.

GbE Interface Configuration
78-4025112-01 Rev H0 35
GbE Interface Configuration
GbE Interface Operation Modes
The RF Gateway 1 has four physical GbE input ports that receive video and data streams from the upstream network. These ports may be used independently (four­port independent mode) or configured to implement input redundancy (Dual port­pair mode).
In software releases 02.02.11 or later, the RF Gateway 1 may be configured for the four physical ports to operate independently. In this mode, no redundancy options are available. Each port will retain its hard-coded MAC address in this mode.
Four-Port Independent Mode
In four-port independent mode, the RF Gateway 1 may be configured for the four physical ports to operate independently. In this mode, no redundancy options are available. Each port will retain its hard-coded MAC address in this mode. All the four ports can belong to the same/different IP subnets.
The four-port independent mode supports redundancy for unicast streams if the ‘Ingress-All’ setting is enabled on the RFGW-1. If the Ingress-All is disabled then all the configured sessions can receive traffic only on the designated input port.
The four-port independent mode does not support redundancy for multicast streams. Multicast sessions can be configured to receive traffic on only one input port.
Ingress-All operation for Unicast Streams in Four-Port Independent Mode
For unicast stream sessions, the input stream can be received on any of the four input ports. The session will latch on to the input port on which the stream is detected first. If a loss of input occurs on the port that is currently receiving the stream, the session will automatically try to detect and switch to other ports where the stream may be available. If none of the input ports are receiving the traffic, then the stream will shut down until any of the ports start receiving traffic.
Source Specific Multicast Operation in Four-Port Independent Mode
When a multicast session is configured on the RFGW-1 with multiple source IP addresses for the input stream, then the RFGW-1 will repeatedly try the sources in the order they are specified (primary, secondary, tertiary and quaternary) until it receives the input stream.
Dual Port-Pair Mode
In port-pair mode, the RF Gateway 1 is preconfigured to implement redundancy as follows. The four input ports are configured to operate as two redundant port-pairs.
Page 60
Chapter 3 General Configuration and Monitoring
36 78-4025112-01 Rev H0
GbE port-pair 1 is composed of physical ports 1 and 2 (either one can be
configured as primary and the other as backup.
GbE port-pair 2 is composed of physical ports 3 and 4 (either one can be
configured as primary and the other as backup.
When operating in the Dual port-pair mode, only one of the physical GBE ports in a pair can be used to receive input traffic (except for the Stream Redundancy detection mode, explained later, where both ports of a pair can be used to receive multicast stream). This port is termed as the Active port of the port pair. If a fault occurs on the current Active port, the RF Gateway 1 will failover to the next physical port.
To facilitate network operation of GbE port redundancy, the RF Gateway 1 implements a single, user-configurable Video/Data IP address for each port-pair. The Video/Data IP address is assumed by the active port of the port-pair. If a failover occurs from an active port to a backup port, the backup port assumes the Video/Data IP address once it becomes active. For all modes of operation, any unicast streams destined for the RF Gateway 1 must be sent to the Video/Data IP address for a given port-pair. The RF Gateway 1 does not implement a layer 2 address. Each physical GbE port is assigned a static, non-configurable MAC address. In this manner, the active physical port of a given port-pair assumes the Video/Data IP address of the port-pair, but retains its own unique hard-coded MAC address.
Several user-configurable options are available to the operator regarding redundancy, including:
- auto vs. manual operation
- revertive vs. non-revertive
- detection mode
Manual Redundancy Mode
The Active port of the pair is set by the user and remains fixed until changed by the user again. It does not depend on the Port or Network status. The active port can be either port 1 or 2 for the first pair and port 3 or 4 for the second pair.
Auto Redundancy Mode
This is the default redundancy mode of the input ports. When operating in the Auto Redundancy mode, the RFGW-1 will dynamically select the Active port for a pair based on the Port and/or the network condition. The user can configure the condition that will trigger the change in the current Active port of the pair. The triggers are referred to as Detection modes. Three different detection modes are available,
Ethernet Link Ethernet Link + UDP/L2TPv3 packets Ethernet Link + UDP/L2TPv3 packets + TS Socket

Ethernet Link
Link status of the ports of pair 1
Active Port
Link for both Port 1 and Port 2 is up.
Port 2
Link for Port 1 is up. Link for Port 2 is down.
Port 1
Link for Port 1 is down. Link for Port 2 is up.
Port 2
Link for both Port 1 and Port 2 is down.
Port 2
The current active port will continue to remain as active until there is a loss of link (cable disconnection or port shutdown on the other end) on that port. If a link loss is detected, the RFGW-1 will try to make the other available port as Active. If the link is not present on both ports, then the last Active port will continue to remain as active (of course without being able to receive any input) until a link is detected on any of the port.
Primary Port and Backup Port
The primary port of a Port-pair is the port which the RFGW-1 will try to make as Active during initialization (e.g. bootup, or when changing the redundancy from manual to auto, or when changing the detection mode of the port-pair). The user can choose either of the port as the primary port for the pair. The other port which is not the primary is termed as Backup port.
Consider the following scenario for example,
Primary port for port-pair 1 is configured as port 2 with detection mode set to Ethernet Link. Then, if during boot up,
Revert to Primary Port
The ‘Revert to Primary’ is a functionality that is available when the RFGW-1 is operating in Ethernet Link detection mode. If this is enabled and if the current active port is the backup port, the RFGW-1 will periodically check the link status on the primary port. If it finds the link has come back, then it will change the Active port as primary port (even though link continues to exist in the backup). The inspection period can be set anywhere from 1 second to 5 minutes.
Ethernet Link & UDP/L2TPv3
The current active port will continue to remain as active until there is a loss of link (cable disconnection or port shutdown on the other end) or loss of traffic (no UDP/L2TPv3 packets – zero input bitrate) on that port. If a link loss is detected or UDP/L2TPv3 loss is detected, the RFGW-1 will try to make the other available port as Active.
Page 62
Chapter 3 General Configuration and Monitoring
38 78-4025112-01 Rev H0
If the link is not present on both ports, the last active port will continue to remain as active. If both the ports has connectivity but none of them is receiving any traffic, then the RFGW-1 continuously changes the Active port to monitor for any traffic and will lock to the port which receive the traffic first.
Revert to primary is not supported when the input ports are operating in this detection mode.
Source Specific Multicast Operation in "Ethernet Link" and "Ethernet Link & UDP/L2TPv3" Modes
The SSM operation is similar to the "4-port independent mode" except that the sources will be tried on the current active port of the pair. The SSM operation also works the same way in the manual redundancy mode.
Ethernet Link & UDP/L2TPv3 & TS Socket
This detection mode is also known as "Stream Redundancy" mode of operation. It
behaves the same way as the ‘Ethernet Link & UDP/L2TPv3’ mode except for
multicast input streams.
The unicast streams will continue to work the same way as in the ‘Ethernet Link & UDP/L2TPv3’ mode. The virtual IP address of the port pair will continue to receive
unicast traffic only through the Current Active Port.
For Multicast streams, both the ports behave as active. i.e. input can be received either from the backup port or the primary port irrespective of whether that port is the Current Active port or not. The Virtual IP address will not be applicable for multicast input streams. Both the ports in the port pair will receive multicast traffic on their physical IP addresses
Since both the ports can be used to receive traffic at the same time, any multicast input stream can be active on any of the port based on its availability. Different sessions can be set up on different ports (of the port-pair) based on which port the stream is available.
When a stream is configured, it will initially get setup on the primary port if it is available. If it is not available on the primary port, it will get set on the backup port if it is available. If the stream is lost on the currently bound port, then the RFGW-1 will automatically switchover the stream to the other port. If a stream is not available on both the ports (of the port pair), then it will be kept toggling between the two ports until it becomes available on any of the port.
The IGMP Joins for multicast streams can be sent on one port or both the ports and is configurable using the ‘Multicast Join port’,
Single port Dual ports
Page 63
GbE Interface Configuration
78-4025112-01 Rev H0 39
Multicast Join on Single Port
In this mode, the IGMP join will be sent only on the port where the stream is active. If the stream is not available on both the ports then the IGMP will be sent on the port which is currently being tried (as the stream will be toggled between both the ports). This is mode is useful when the user wants to restrict the unnecessary traffic being received.
Multicast Join on Both Ports
In this mode, the IGMP join is sent on both the ports of the pair irrespective of on which port the stream is active. The switching time for stream, in case of loss, will be improved when operating in dual join mode. Also the user can ascertain, from the GUI pages, if the traffic is being received on the alternate port and is ready for switchover in case of input loss.
Reversion of Multicast Stream to Primary Port
The ‘Stream Redundancy,’ as with the Ehternet Link + UDP/L2TPv3 traffic mode of
operation, does not support the reversion of Active port to Primary port.
But it supports the reversion of the multicast input streams to primary port, manually. When this option is selected, all the multicast input streams that are active on the backup port will be forced to become active on the primary port. If the stream is not available on the primary port, it will again switch and become active on the
backup port. The user can also use the ‘Periodic revert to primary for multicast streams’ option to schedule this operation hourly or weekly.
Source Specific Multicast operation in "Stream Redundancy" mode of operation
The SSM operation works slightly different from the 4-port independent mode and the other Dual port pair modes.
Under this mode, since the traffic can be received on both ports of the pair, any given source IP will be tried on both the ports before the other sources are tried.
For example, if a session is created on pair-1 with four sources configured, then the RFGW-1 will try to bind the stream to the primary source on the primary port of pair-1. If the source is available it will lock to it. But if it is not available, then it will try to bind to the same primary source on the backup port. If the primary source is not available on both the ports, the secondary source will first be tried on the primary port and if it is not available then on the backup port. In this way, both ports of the pair will be attempted before switching to the next source IP. The port switching takes priority over the source switching when the RFGW-1 is operating in the stream redundancy mode.
Page 64
Chapter 3 General Configuration and Monitoring
40 78-4025112-01 Rev H0
Ingress-All operation for unicast streams in Dual Port Pair mode
When the ‘Ingress-All’ setting is enabled on the RFGW-1, the unicast streams can be received on either the Current Active port (virtual IP) of Pair-1 or Pair-2. If the unicast stream is lost on Active port of pair-1, it will get setup on Active port of pair­2 and vice-versa. In effect, the unicast stream will have two input ports.
For network debugging and connectivity testing, each of the four physical GbE input ports are also user-configurable for the IP address, and will respond to PING. Since the GbE input ports are not configurable for default gateway, a static route to the source network of the PING must be added to the GbE port to facilitate PING responses over layer-3 networks. Static routes can be added via the GUI, using the System/ARP & Routes page.
Gratuitous ARPs can be enabled for the active GbE ports of the Port-Pairs. Using gratuitous ARP, the RF Gateway 1 makes only the virtual IP address known to the network. At layer 2, the RF Gateway 1 advertises the unique MAC address of the physical active port. The gratuitous ARP function generates ARP's for both the virtual interface as well as the physical interface.

78-4025112-01 Rev H0 41
Treat PCR Zero Bitrate as Content Loss
When a stream's PCR PID is not available, we would treat the scenario as similar to content loss and initiate the input stream switch to the backup stream. The switch to the backup stream is initiated without checking for presence of stream on the backup port. The switch rules would be same as Socket Redundancy (port switching has higher priority over source switching)
The stream should have a valid PCR reference. This feature is applicable only for SPTS streams.
Manual Stream Switching
On a per stream basis, there will be a setting that will trigger the failover of the stream to the other port. This setting would be used to toggle a stream across ports. This setting is only for multicast streams available on ports configured for socket redundancy.
This button is available on the Monitor->Input->Stream Replications pop up window. Once the stream is toggled, the stream would switch based on the socket redundancy priorities (port switching has higher priority over source switching).

ARP and Route Configuration
To facilitate network connectivity on the management and GBE interfaces, the RF Gateway 1 can create static Route and ARP entries. Static routes provide network connectivity to devices that are not on the network. For example, a static route could be required to support multicast sessions on the GbE interface from a device on another network. Static ARPs are provided to allow connectivity to devices that are not responding to ARP requests. Depending on network configuration and requirements, static ARPs or routes may be required on any of the management or GbE interfaces.

Clock Configuration
The RF Gateway 1 provides several different configuration options for obtaining and maintaining accurate time on the system. These options include time synchronization from a network time server and obtaining time from an on-board real-time clock (RTC).
Real -Time Clock Setup
The RF Gateway 1 has an on-board, real-time clock (RTC) with battery back-up which can be used to provide system time. The RTC can be set manually via the web interface or configured to be updated with network time obtained from an SNTP server. The Synchronize With Server parameter is used to control the RTC synchronization behavior. When set to Disabled, the RF Gateway 1 obtains system time from the RTC at startup. Once set, the internal system clock runs independently until the RTC is changed. The Clock Configuration page provides the following user-configurable options.
Current Time New Time Synchronize with Server
To Set the Real Time Clock:
1 Navigate to the System/Clock page.
Result: The Clock Configuration page is displayed.
2 In the New Time field, enter year, date and current time.
Example: 2008/06/17/0052:26

4 Click OK.
Result: The time is displayed in the Current Time window.
Simple Network Time Protocol (SNTP)
When Synchronize With Server is set to Enabled, the RF Gateway 1 periodically attempts to obtain network time from one of the SNTP servers specified by the IP address on the Clock Configuration page. If communication with the SNTP server is successful, the RTC and internal system clock are updated. If communication with both SNTP servers fails the internal system clock updates with a value obtained from the RTC. For the remainder of the synchronization interval, the system runs on its own time independent of the RTC and network server. At the start of the next synchronization interval, the system attempts to resynchronize with the network time server and set its clocks accordingly.
To Set the SNTP server for RTC
1 Navigate to the System/Clock page.
Result: The Clock Configuration page is displayed.
2 Set Synchronize with Server to Enabled. 3 In the Main SNTP Server IP Address field, enter the IP address in xx.xx.xx.xx

Session Refresh
The RFGW-1 generates an input pid conflict alarm (Alarms/Events section) if any ES or the PMT pid in an MPTS is the same as a pid already in use in the same MPTS. Recall that it is the user's responsibility to ensure that the pids in an MPTS are unique. To clear the pid conflict alarm it is necessary to not only resolve the input pid conflict at the source e.g. the DCM but also to refresh the associated sessions as seen in the following screen shots. Recall that the pid conflict is to be resolved before refreshing the session.
Once input PID conflict is detected, the services that are involved in the conflict will not be routed to the output.

The RF Gateway 1 supports automatic detection and user notification of changes in the system. Changes may be classified as either Events or Alarms. Alarms carry a state while events are important instances that occur in time and are reported. For example, Link Lost and Link OK are two well-defined states and are associated with an alarm. Events Startup, Configuration Backup, and Second Power Supply Inserted do not have a state but are important events reported by the system.
System Alarms
System Alarms are conditions with state that occur on the system that the user may want to be aware of. The RF Gateway 1 provides user notification of changes in alarm state. These notifications can be via SNMP traps, system log or the front panel fault LED. System alarms can not be masked or filtered and will always be indicated on the system.
The default alarms supported by the system are defined in the alarm configuration area of the database. The default alarm configuration parameters include items such as alarm label, severity, mask, threshold, and enabled notifications. These parameters are defaults and are not configurable through the web interface.
While active, the system maintains additional information on each of the alarms such as alarm originator, state, instance, and other descriptive details including triggering threshold, actual value, and units. Alarms have two possible state values, Alarm and Clear. Each alarm has two possible severity levels, Critical or Major. The supported alarms are described in the following table.

System Events are conditions without state that the user may want to be aware of. The RF Gateway 1 provides user notification of these events. These notifications can be via SNMP traps or the system log. System events cannot be masked or filtered and will always be indicated on the system.
The default events supported by the system are defined in the event configuration area of the database. The default event configuration parameters include items such as event label, mask, and enabled notifications. These parameters are defaults and are not configurable through the web interface.
The system reports additional information on actual events such as event originator, instance, and other descriptive details including triggering threshold, actual value, and units. Supported events are described in the following table.

User Notification of Alarms and Events
The system provides notifications of Alarms and Events in a variety of ways. These include Front Panel Alarm Indication, Alarm Table (web interface), SNMP Traps and Log Entries.
Front Panel Alarm Indication
A fault LED on the front panel is provided to allow quick and easy notification of an alarm existing on the system. When one or more alarms are active, the LED is solid red. When no alarms are active, the LED is off. The fault LED blinks during system boot but stabilizes to indicate alarm status after the system has initialized.
Alarm Table
The alarm table is another indicator of alarm status. The table is accessible through the web interface and provides detailed information regarding alarm status. A condensed version of the alarm status is also available on the Summary page of the web interface. The alarm table is shown below.
Page 93
Fault Management of the RF Gateway 1
78-4025112-01 Rev H0 69
SNMP Traps
SNMP traps may also be used to provide notification of system alarms and events. The SNMP & Traps page of the web interface allows for configuration of trap receivers for this purpose. When configured, SNMP traps will be sent for all system alarms and events. The RF Gateway 1 supports SNMP V1 and V2 traps and a trap community string as shown below.
Active Alarms Table
The active alarms table is a dynamic table containing all currently active alarms. This table is accessible using the OID rfgw1ActiveAlarmTable (1.3.6.1.4.1.1429.1.12.1.2.14.1). A detailed description of the table can be found in the SA-RFGW-1-MIB proprietary MIB.
System Log
The system log provides a record of alarms and events that have occurred on the system. Log entries are always provided for each system alarm and event. The system is also capable of lower level logging for more detailed monitoring. In this case, log filtering is provided to control the type and level of information written to the log. The logged information can be categorized as module-related or low-level alarms. An example of a log screen showing various alarms and events on the system is shown below. An intuitive user interface is provided to navigate through the logs, delete logs and save logs to a file.

Configuration Management
Configuration Save
The RF Gateway 1 allows configuration changes to be saved to the files in the flash file system. Configuration information can be classified as platform-generic or platform-specific. Platform-generic information applies to many systems while platform-specific applies to individual systems. For example, IP addresses and system name or location are platform-specific parameters. QAM card configuration is considered generic and common to many systems. This segregation provides the ability to clone and distribute system configuration throughout the network. Platform-generic information is saved by clicking the Save button at the top of the web interface page.
This operation performs a global save of the RF Gateway 1 configuration. The configuration information is saved in the file /tffs0/rfgw_xml_db.gz in the flash with a backup copy also kept in /tffs0/rfgw_xml_db_bkup.gz. Once saved in the flash, the system configuration file can then be transferred to a remote FTP server as described in Configuration Backup (on page 74).
The platform-specific configuration parameters are saved in a different set of files, /tffs0/rfgw_ot.xml for primary and /tffs0/rfgw_ot_bkup.xml for backup. These files are updated as certain parameters are changed from the web interface. These parameters are unlikely to change after their initial configuration.
Software version 1.3.11 has an automatic save feature which allows applied database changes to be automatically saved to preserve them in nonvolatile memory.
Configuration Backup
The RF Gateway 1 performs configuration backup via FTP to a backup server. The backup databases generally contain QAM parameters, channel application modes and mapping tables. The backup databases generally do not include IP networking settings (including management as well as GbE input port parameters).
To Backup Configuration
1 Navigate to the System/Backup Configuration window.
