QAM Annex and Frequency Plan Configuration 78-4025112-01 Rev H0 27 3 In the Frequency Plan field, select the desired frequency plan. The standard plan has channels mapped to pre-set frequencies used in North America. The custom plan lets you choose frequencies. ITU-A and ITU-C have custom plans only. 4 Click Apply. 5 Click Save. 6 Reboot the device. Reboot/power-cycle is required after changes to the annex setting.
Chapter 3 General Configuration and Monitoring 28 78-4025112-01 Rev H0 QAM Card Configuration The RFGW-1 has six QAM cards. Each card has two ports. Each port has four channels. The following sections describe how to configure the QAM card. Global RF Port Configuration Global RF Port Configuration allows you to configure RF for every port. See the following screen. Parameters The following table describes Global RF Port Configuration parameters. Parameter Description RF Port Refers to the RF port on a particular card. Example: 1/2 indicates card 1, port 2. Spacing The spacing between the channel center frequencies of different channels. Modulation Refers to the QAM output selected (256 or 64). Output Level Refers to the QAM output. The range depends on other parameters. Symbol Rate Based on the QAM modulation and ITU standards. Combined Carrier Allows you to configure the port for single/dual/quad channel.
QAM Card Configuration 78-4025112-01 Rev H0 29 Parameter Description ITU Carrier Number This field is only seen if your annex is ITU-B and you have a standard frequency plan selected. Example: In North America, channel 50 is determined to have a center frequency of 381 MHz. Selecting the first channel number picks up the corresponding frequency for channel 1 on that port. The remaining frequencies are populated automatically by channel spacing. Based on those frequencies, the remaining channel numbers are populated. Note: There are certain restrictions on the channel number. Carrier Center Frequency Allows you to choose the center frequency of channel 1 and the remaining channels are populated automatically. Notes: There are certain restrictions on the channel number. When changing the center frequency of a carrier, all carriers on the associated port are muted for several seconds to prevent spurious emission. QAM Card View The RFGW-1 chassis can be populated with up to six QAM line cards. Verifying the QAM Card Follow the instructions below to verify the QAM card. 1 Navigate to the QAMS page. 2 In the tree menu, select the desired QAM card. Result: The web view indicates the status of the QAM card.

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 (four- port independent mode) or configured to implement input redundancy (Dual port- pair 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.
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
