Feature Overview

This document describes the multipoint headend system. For a description of the subscriber unit system, refer to the Multipoint Wireless Support for the Cisco 2600 and 3600 Series Routers document.

Multipoint Headend System

The Cisco broadband fixed wireless multipoint headend system is designed to use antennas that transmit the RF signal in a portion of a complete circle, or directionally, in what is called a sector. Each headend site can be designed and configured to broadcast in a single sector, or in multiple sectors, depending on the requirements of the network.

For each sector, the components of a multipoint headend system (see Figure 1) consist of the necessary cables and:

•One Cisco uBR7200 series universal broadband router

•One wireless modem card installed in the router

•One power feed panel

•One or two antennas (second antenna for diversity reception is optional)

•One or two wireless transverters containing the RF amplifier (one for each antenna)

•One or two duplexers (one for each wireless transverter)

Figure 1 Components of the Multipoint Headend System (transverter hail shield not shown)

Multipoint Headend Components

Router

The Cisco uBR7200 series are designed for two-way transmission of digital data using either coaxial cable or broadband fixed wireless signals. These routers support IP routing with a wide variety of protocols and any combination of Ethernet, Fast Ethernet, High-Speed Serial Interface (HSSI), serial, and Asynchronous Transfer Mode (ATM) media. Network interfaces reside on port adapters that provide the connection between the router and external networks. Cable or wireless interfaces reside on modem cards and provide the connection to cable or wireless networks.

Other features include:

•Online insertion and removal (OIR)—Add, replace, or remove a port adapter and modem cards without interrupting the system or entering any console commands

•Downloadable software—Load new images into Flash memory remotely, without having to physically access the router

For further information regarding the Cisco uBR7200 series, including detailed installation and configuration instructions, refer to the Cisco uBR7200 Series Universal Broadband Router Installation and Configuration Guide.

Wireless Modem Card

The wireless modem card installs in a modem card slot of a Cisco uBR7200 series. It is configured through the router's system console or via the CiscoView network management system. The wireless modem card provides the control and data interface to the system's digital motherboard and the radio frequency (RF) subsystem in the wireless transverter. It also provides the up/down conversion from baseband to intermediate frequency (IF).

The wireless modem card consists of the following components:

•Digital motherboard

•IF analog board

•10-MHz input connection for external reference clock signal (external reference clock is optional)

•10-MHz output connection for forwarding optional external reference clock signal to another wireless modem card

•Monitor connections for monitoring the power feed panel connections (main and diversity)

•Power feed panel connections (main and diversity)

•Light-emitting diodes (LEDs) that provide a visual indication of the state of the modem card

For further information regarding the wireless modem card, including detailed installation and configuration information, refer to the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation document.

Power Feed Panel

The power feed panel serves as an interconnection device between the wireless modem card, the wireless transverter, and a -48 VDC power supply. The main purpose of this unit is to provide DC power to the system, provide control signals to the wireless transverter, and transmit and receive IF signals to and from the transverters. In addition, the unit contains circuit breakers for the DC power.

The power feed panel consists of the following components:

•Coaxial cable connection ports to the wireless modem card on the front panel

•Power ON/OFF switches on the front panel, with LED power indicators

•Coaxial cable connection ports to the wireless transverter on the rear panel, with LED power indicators

•DC power supply terminal blocks on the rear panel

At least one power feed panel is required for each installation. Each power feed panel supports a maximum of four wireless transverters.

For further information regarding the power feed panel, including detailed installation information, refer to the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation document.

Wireless Transverter

The ruggedized wireless transverter is the outdoor data interface to the indoor subsystems. It provides up/down conversion from IF to RF frequencies.

The wireless transverter consists of the following components:

•RF head

•Connector port for IF input, power, and control signal

•Duplexer assembly with antenna connection

For further information regarding the wireless transverter, including detailed installation information, refer to the Cisco uBR7200 Series Router Multipoint Wireless Modem Card and Subsystem Installation document.

Benefits

The broadband fixed wireless multipoint system provides:

•Fast, easy deployment

•Flexibility—Various interfaces to the host routers and numerous network deployment plans

•End-to-end Cisco IOS network, enabling multiservice security, multimedia, and management support

•Scalable network growth through the addition of more cells or sectors

•Full-duplex data rates of up to 22 Mbps

•Non-line-of-sight (Non-LOS) Vector Orthogonal Frequency Division Multiplexing (VOFDM) technology, enabling greater service coverage

Configuration Tasks

This section discusses the following configuration tasks for the multipoint fixed wireless feature:

•Multipoint CLI Commands Classification

•Overriding the Default Microcode Path

•Configuring IF Loopback (Optional)

•Configuring RF Loopback (Optional)

•Setting the Power Levels and Frequencies

•Configuring the Automatic Level Control (ALC)

•Configuring the Modulation Profile for a Wireless Link

Multipoint CLI Commands Classification

The multipoint headend system CLI commands are classified as follows. Click on the link to go to the list of commands under each class.

•Startup Commands

•Installation and Configuration Commands

•Verification Commands

•Operating Commands

•Monitoring Commands

•Troubleshooting Commands

Note This classification is made to help the user in chunking the commands. Some of the commands can be listed under any of these groups.

Overriding the Default Microcode Path

The wireless line card requires external microcode images in order to operate. The Cisco IOS software has a default file path where it looks to find the microcode and the microcode version. For routers that are configured with line cards at the factory, the path and version of the microcode image in flash memory matches the default setting and allows the line card to come up without any additional configuration. However, you may want to override the default microcode path, for example, to upgrade your software to the latest release. Use the following steps to change the path for the microcode.

Command

Purpose

Step 1

Router# dir flash

Displays the content of the Flash memory.

Step 2

Router# show microcode

Displays the default path for the microcode.

Step 3

Router# config t

Enters the global configuration mode.

Step 4

Router(config)# microcode cwrhe bundle-path

Specifies the a new path for the headend microcode bundle.

Step 5

Router(config)# end

Exits the global configuration mode and enters the EXEC mode.

Step 6

Router# show microcode

Displays the specified path for the microcode.

Step 7

Router# microcode reload cwrhe

Loads the microcode onto the line card.

Step 8

Router# copy running-config startup-config

Saves the path for the microcode so that the microcode is loaded from the new path the next time the router is rebooted.

Configuring IF Loopback (Optional)

An IF loopback confirms that the hardware is seated properly in the chassis and that the analog and signal processing portions of the wireless modem card are functioning as expected. Loopback does not test forward error corrections (FEC) and MAC-layer interface of the line card; other tests must be done for these portions of the line card. Each receive path must be tested individually when there are two antennas employed.

Use the following commands to execute an IF loopback. Specifying these commands shuts down the radio link and initiates the IF loopback.

Command

Purpose

Step 1

Router(config-if)# shut

Stops the interface.

Step 2

Router(config-if)# loopback local if main 2

Configures the IF to loop the lower half of the channel.

Step 3

Router(config-if)# no shut

Brings up the loopback mode.

Step 4

Router(config-if)# shut

Stops the interface.

Step 5

Router(config-if)# loopback local if main 3

Configures the IF to loop the upper half of the channel.

Step 6

Router(config-if)# no shut

Brings up the loopback mode.

Step 7

Router(config-if)# shut

Stops the interface.

Step 8

Router(config-if)# no loopback

Removes the loopback commands used up to this point.

Step 9

Router(config-if)# no shut

Establishes link.

If a second antenna is employed, its receive path must also be tested. Use the following commands to configure the second antenna. Issue the show running-configuration command to see the IF configuration.

Command

Purpose

Step 1

Router(config-if)# shut

Stops the interface.

Step 2

Router(config-if)# loopback local if diversity 2

Configures the IF to loop the lower half of the channel for antenna 2.

Step 3

Router(config-if)# no shut

Brings up the loopback mode.

Step 4

Router(config-if)# shut

Stops the interface.

Step 5

Router(config-if)# loopback local if diversity 3

Configures the IF to loop the upper half of the channel for antenna 2.

Step 6

Router(config-if)# no shut

Brings up the loopback mode.

Step 7

Router(config-if)# shut

Stops the interface.

Step 8

Router(config-if)# no loopback

Removes the loopback commands used up to this point.

Step 9

Router(config-if)# no shut

Establishes link.

Configuring RF Loopback (Optional)

An RF loopback confirms that the wiring to the transverter is correct, that communication has been established from the line card to the transverter, and that the transverter is operating correctly. (It does not test the duplexer, which is the final stage before the signal is sent to the antenna.) Also, loopback does not test forward error corrections (FEC) and MAC-layer interface of the line card; other tests must be done for these portions of the line card. Because there is only one transmit path, the path to each transverter must be tested separately. Use the following commands to configure the RF loopback.

Command

Purpose

Step 1

Router(config-if)# shut

Stops the interface.

Step 2

Router(config-if)# loopback local rf main 2

Configures the RF to loop the lower half of the channel.

Step 3

Router(config-if)# no shut

Brings up the loopback mode.

Step 4

Router(config-if)# shut

Stops the interface.

Step 5

Router(config-if)# loopback local rf main 3

Configures the RF to loop the upper half of the channel.

Step 6

Router(config-if)# no shut

Brings up the loopback mode.

Step 7

Router(config-if)# shut

Stops the interface.

Step 8

Router(config-if)# loopback local rf diversity 2

Configures the RF to loop the lower half of the channel for antenna 2. Note that this command is issued only if a second antenna is used.

Step 9

Router(config-if)# loopback local rf diversity 3

Configures the RF to loop the upper half of the channel for antenna 2. Note that this command is issued only if a second antenna is used.

Step 10

Router(config-if)# no shut

Brings up in loopback mode.

Step 11

Router(config-if)# shut

Stops the interface.

Step 12

Router(config-if)# no loopback

Removes any loopback commands used up to this point.

Step 13

Router(config-if)# no shut

Establishes link.

Issue the show running-configuration command to see the RF configuration.

Configuring the Modulation Profile for a Wireless Link

The modulation profile describes the physical layer configuration of a wireless channel. The correct settings to use are the result of extensive site planning and quality-of-service models. The specified settings are stored in the router as profiles. These profile settings are entered in the router only once, but can be applied to multiple line cards in the router.

Command

Purpose

Step 1

Router# show radio capability modulation-profile int radio slot/port

Displays the modulation profiles supported by the radio card installed in a particular slot/port.

Step 2

Router# configure terminal

Router(config)# end

Exits the interface configuration mode and enters the EXEC mode.

Step 5

Router# show radio modulation-profile

Displays the modulation-profile configuration settings that the user specified.

Step 6

Router# configure terminal

Enables the global interface configuration mode.

Step 7

Router(config)# interface radio slot/port

Enters radio interface configuration mode.

Step 8

Router(config-if)# radio upstream usport subchannel sn modulation-profile p

Applies the modulation profile to an upstream port.

Setting the Power Levels and Frequencies

The power levels must be set correctly to ensure correct operation and compliance with the governing regulatory bodies (such as the FCC). After the power settings have been determined, use the following commands to configure the router.Refer to the following subchannel map as a reference for the subchannel assignments:

Downstream Channel

Command

Purpose

Step 1

Router(config-if)# radio transmit-power power-level

Sets the upstream transmit-power to power in dBm.

Step 2

Router(config-if)# radio downstream frequency freq width width

Sets frequency and bandwidth for the downstream channel.

Step 3

Router(config-if)# radio downstream subchannel sc modulation-profile p

Sets the subchannel and modulation-profile assignment for the downstream channel.

Note This command specifies the center frequency and width of the basic hardware channel. The downstream channel itself can be full, one-half, or one-quarter of this bandwidth. For example, the only basic channel bandwidth that is supported by the initial hardware release is 6.0 MHz.

Upstream Channel

Command

Purpose

Step 1

Router(config)# radio upstream frequency freq width width

Sets the upstream frequency and bandwidth.

Note The width parameter specifies the bandwith for the upstream channel group (the basic hardware channel). The freq parameter specifies the center frequency for this group of upstream channels. For example, the only basic channel width that is supported by the initial hardware release is 6.0 MHz.

Step 2

Router(config-if)# radio upstream usportnum subchannel sn modulation-profile p

Sets the subchannel and modulation-profile assignment for the upstream channel.

Note The bandwidth of the subchannel must match the bandwidth of the modulation-profile.

Step 3

Router(config)# radio transmit-power power-level

Sets the downstream transmit power to power in dBm.

Step 4

Router(config-if)# radio upstream usportnum target-receive-power power-level

Sets the target receive power in dBm for the upstream port. The usportnum field specifies the upstream port number. The target receive power must be set for each upstream port.

Step 5

Router(config-if)# radio upstream usportnum shutdown

Shuts down the upstream channel.

Configuring the Automatic Level Control (ALC)

The automatic level control (ALC) module governs the individual transmit power levels of all the subscriber units. The purpose of ALC is to ensure that the target receive power at the headend is maintained over time by taking power measurements of all the subscribers many times per second. Taking power measurements in small intervals results in better resilience to the fading environment, but it consumes more upstream bandwidth. ALC can be disabled, but this is not recommended because it results in poor upstream link performance. The current system allows only one interval setting for an entire sector. The default interval is 96 ms.

Command

Purpose

Step 1

Router# configure terminal

Enables the global interface configuration mode.

Step 2

Router(config)# interface radio slot/port

Specifies the line card to be configured. In this example, the line card installed in a specific slot/port number.

Step 3

Router(config-if)# radio alc interval interval

Configures the ALC interval for the sector at a specified interval value.

Step 4

Router(config-if)# end

Exits the interface configuration mode and get to the EXEC mode.

Step 5

Router# show interface radio slot/port alc

Displays the ALC setting that you specified.

Verifying the Wireless Modem Card Configuration

Step 1 Enter the show running-configuration command in privileged EXEC mode to display the configuration currently in effect on the Cisco uBR7200 series.

Step 2 Enter the show startup-configuration command in privileged EXEC mode to display the system startup configuration.

A miss is the number of times a radio subscriber does not acknowledge a MAC layer keep-alive message from a subscriber unit. When the number of misses exceeds the threshold, the radio subscriber unit is placed in the flap list. To disable the miss threshold as a criterion for adding a radio subscriber unit to the flap list, use the no form of this command.

This command was introduced.

12.1(3)XQ1

Support for multipoint radio modem was added.

Usage Guidelines

A histogram is a collection of statistics sampled over time on a burst-by-burst basis and presented as a function of bins.

The data for the histogram is collected as soon as the command succeeds and continues until either the specification is deleted using the no option, or the specified duration expires. The collected data is printed out to the console at user-specified intervals.

A histogram statistic is created when data is sampled for every burst. For each sampled burst, the count in a specific bin is incremented.

Note There should be no measurable impact or degradation of router performance from running histograms. Cisco recommends that you keep the number of histograms that you are running simultaneously to a minimum, and that you terminate any histograms no longer needed.

Note Histograms and timelines share the same DSP memory. A total of 10 histograms and timelines can be created on a single DSP. There are a total of 8 locations for fine histograms and timelines and 5 locations for coarse histograms. The combination of histograms and timelines must be less than 10.

Examples

The following example shows how to configure a histogram specification. The histogram collection starts as soon as the command succeeds. A histogram is collected for signal-to-interference plus noise ratio on channel 3. The remaining of the parameters are optional, and the system picks default values.
UBR04(config-if)# radio histogram sinr-ant1 3

radio insertion-interval

To control the frequency at which the headend schedules opportunities for the subscriber-unit to join the network, use the radio insertion-interval interface configuration command. A subscriber unit's request to join the network for the first time is called initial ranging. The default insertion interval setting configures the Cisco uBR7200 series to automatically vary the initial ranging times that are available to the new subscriber unit that attempts to join the network. To use the automatic (default) setting, use the no form of this command.

radio insertion-interval [fixed-value | automatic] [millisecond]
no radio insertion-interval
Syntax Description

fixed-value

Specifies fixed period between initial ranging slots in milliseconds (ms). Valid range is 100 to 2000 ms.

automatic

The automatic (default) insertion interval setting configures the Cisco uBR7200 series to automatically vary the initial ranging times that are available to the new subscriber unit that attempts to join the network. Optionally, you can set the lower bound on period between initial ranging slots. The range for this value is 20 to 120 ms.

A 32-bit integer value.

repeat-time

Identifies how much time is left before another event of the same type is generated when oscillating across a threshold.

clear-time

Identifies how long the signal stays below a threshold before another event is generated.

dsp

Specifies one of the following digital signal process (DSP) numbers (dspNum): dsprx0, dsprx1, dsprx2, or dsprx3.

Defaults

No default behavior or values.

This command was introduced.

Usage Guidelines

The following describes how clear-time and repeat-time work for the three scenarios:

1. If clear-time is any value and repeat-time is 0, the user is notified whenever one of the following threshold conditions are met: {high-thresh | low-thresh | up-change | down-change | pos-crossing | neg-crossing}.

2. If clear-time is greater than 0 and repeat-time is 0, the following occurs:

a. When a threshold condition is met for the first time, the user is notified.

b. When a threshold condition does not occur for the length of clear-time, the user is notified and the cycle continues with Step 2a.

3. If both clear-time and repeat-time are greater than 0, the following occurs:

a. When one of the threshold conditions occurs for the first time, the user is notified. After the first notification, no more notifications are sent for the length of repeat-time. At the end of repeat-time, the user is notified indicating how many times the user was not notified when the threshold condition occurred.

b. When a threshold condition stops being met for the length of clear-time period, the user is notified then the cycle starts with Step 3a.

Examples

The following example configures threshold specification for sinr-ant1 on channel 0:
Router(config-if)# radio threshold sinr-ant1 0 high 30

radio timeline

To configure a timeline collection specification, use the radio timeline interface configuration command. To delete a timeline, use the no form of this command.

radio timeline statsParams {MAC-address | chan-id} size [dsp dspNum] [print-options {on | off}] [sampling-period] [tone {circular | average | number toneVal}]
[Trigger threshParams threshType postTrigBufmgt]
no radio timeline statsParams {MAC-address | chan-id}
Syntax Description

statsParams

{sinr-ant1 | sinr-ant2 | sinr-total | timingOffset | rf-rx-power-ant1 | rf-rx-power-ant2 | chan-delay-spread-ant1 | chan-delay-spread-ant2 | power-amb}

The data for the radio attribute is collected as a histogram.

sinr-ant1

Signal-to-interference plus noise ratio for antenna 1.

sinr-ant2

Signal-to-interference plus noise ratio for antenna 2.

sinr-total

Signal-to-interference plus noise ratio for antennas 1 and 2.

timingOffset

Represents the timing delay variations detected in the radio link.

rf-rx-power-ant1

Represents the receive power at the main RF headend (antenna gain is not included).

rf-rx-power-ant2

Represents the receive power at the diversity RF headend (antenna gain is not included).

chan-delay-spread-ant1

The offset for channel delay spread on antenna 1.

chan-delay-spread-ant2

The offset for channel delay spread on antenna 2.

power-amb

Represents the noise floor of the ambient environment, in decibels.

MAC-address

Specifies a particular subscriber unit.

chan-id

Specifies an upstream channel ID. Valid values are 0 to 3.

size

Specifies the number of values to be collected.

dsp

Specifies one of the following digital signal process (DSP) dspNum values: dsprx0, dsprx1, dsprx2, or dsprx3.

print-options

on or off.

sampling-period

Specifies, in seconds, the frequency of data collection.

Trigger

Specifies when the collection of data must stop. Trigger identifies a threshold specification. When the threshold is reached, the timeline collection is stopped.

threshParams

Has same attributes as statsParams.

threshType

{high-thresh | low-thresh | up-change | down-change | pos-crossing | neg-crossing}

high-thresh

Specifies that the threshold condition is met when the value being monitored is above threshValue.

low-thresh

Specifies that the threshold condition is met when the value being monitored is below threshValue.

up-change

Specifies that the threshold condition is met when the positive change of the value being monitored is greater than threshValue.

down-change

Specifies that the threshold condition is met when the negative change of the value being monitored is greater than the threshValue.

pos-crossing

Specifies that the threshold condition is met when the value being monitored does a positive crossing (positive increase) of the threshValue.

neg-crossing

Specifies that the threshold condition is met when the value being monitored does a negative crossing (negative increase) of the threshValue.

postTrigBufMgt

Specifies the position (position 1 or 2) of the trigger in the data collected. If the trigger position is 1, then most of the data collected before the trigger is returned. If the trigger position is 2, most of the data returned is captured after the occurrence of the trigger.

Defaults

No default behavior or values.

12.1(3)XQ1

This command was introduced.

Usage Guidelines

A timeline is a sequence of data values collected for a specified attribute. The amount of data collected is controlled by the size parameter. The maximum size is 1000 points.

Collection starts as soon as the command succeeds, and continues until the Trigger option occurs or the radio interface radio tl-stop command is entered.

Note Histograms and timelines share the same digital signal process (DSP) memory. A total of 10 histograms and timelines can be created on a single DSP. There are a total of 8 locations for fine histograms and timelines and 5 locations for coarse histograms. The combination of histograms and timelines must be less than 10.

Examples

The following example shows how to configure a timeline specification. The collection process starts as soon as the command succeeds. It collects a timeline for sirn-ant1. The timeline is collected on channel 3. The timeline size is 600 points. The rest of the parameters are optional and the system picks default values.
UBR04# radio timeline sinr-ant1 3 600

radio transmit-power

To set the transverter to transmit the specified amount of power (in dBm) when in operation, use the radio transmit-power interface configuration command. To disable this function, use the no form of this command.

radio transmit-power power-level
no radio transmit-power
Syntax Description

power-level

Positive number representing power stated in dBm. Transmit power range is between 4 and 33 dBm.

Defaults

No default behavior or values.

12.1(3)XQ1

Supported on the fixed wireless multipoint product.

Usage Guidelines

Maximum transmission power is limited by the capabilities of the transverter. In addition, your country's telecommunications authority (the FCC in the United States) regulates the maximum power. It is the responsibility of the installer and operator to comply with the relevant regulations.

To support the maximum number of users in an area, keep the power as low as possible while maintaining sufficient margin and performance. Refer to the Cisco Broadband Fixed Wireless Site Planning Guide for additional information.

Note The command takes effect on the next no shut.

Examples

The following example shows how to set the transmit power to +25 dBm:
UBR04(config-if)# radio transmit-power 25
