Feature Overview
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

Multipoint Wireless Support for the Cisco uBR7200 Series Universal Broadband Router
Configuration Tasks
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
Router# dir flash
Step 1
Step 2
Step 3
Step 4
Displays the content of the Flash memory.
Displays the default path for the microcode.
Enters the global configuration mode.
Router# show microcode
Router# config t
Router(config)# microcode cwrhe bundle-path
Specifies the a new path for the headend
microcode bundle.
Router(config)# end
Step 5
Exits the global configuration mode and enters the
EXEC mode.
Router# show microcode
Step 6
Step 7
Step 8
Displays the specified path for the microcode.
Loads the microcode onto the line card.
Router# microcode reload cwrhe
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
Router(config-if)# shut
Step 1
Step 2
Stops the interface.
Router(config-if)# loopback local if main 2
Configures the IF to loop the lower half of the
channel.

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.

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.

upstream port number. The target receive power
must be set for each upstream port.
Router(config-if)# radio upstream usportnum shutdown
Step 5
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
Router# configure terminal
Step 1
Step 2
Enables the global interface configuration mode.
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.

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.

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.

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.

Usage Guidelines
The Cisco uBR7200 series universal broadband routers maintain a database of flapping radio subscriber
to assist in locating problems. The flapping radio modem detector tracks the upstream and downstream
performance of all radio modems on the network, without impacting throughput and performance or
creating additional packet overhead on the network. The radio modem flap list keeps track of the radio
modem MAC address, up and down transitions, registration events, missed periodic ranging packets,
upstream power adjustments, and the physical interface on the Cisco uBR7200 series.
The flap list collects the following station maintenance statistics:
•
•
•
Detects interface up/down flap; the reinsertion counter counts the number of times a radio modem
comes up and inserts into the network. This helps identify potential problems in the downstream,
because improperly provisioned radio modems tend to try to reestablish a link repeatedly.
Detects intermittent upstream; the keepalive hits versus misses is the number of times radio
modems do not respond or do not respond to the MAC layer keepalive messages. A number of
misses indicates a potential problem in the upstream.
Lists radio modem MAC addresses sorted by flap rate or most recent flap time.
Use the following suggestions for interpreting different network conditions based on the flap-list
statistics:
•
Condition 1: Low miss/hit ratio, low insertion, low flap counter, and old timestamp.
Analysis: This exhibits an optimal network situation.
•
Condition 2: High ratio of misses over hits (> 10%)
Analysis: Hit/miss analysis should be done after the Ins count stops incrementing. In general, if
the hit and miss counts are about the same order of magnitude, then the upstream may be
experiencing noise. If the miss count is greater, then the modem is probably dropping out frequently

and not completing registration. The upstream or downstream is perhaps not stable enough for
reliable link establishment. Very low hits and miss counters and high insertion counters indicate
provisioning problems.
•
Condition 3: High insertion rate.
Analysis: If link reestablishment happens too frequently, then the modem probably is having a
registration problem.This is indicated by a high Ins counter which tracks the Flap counter.

Table 3

Insertions (Ins)
Link insertion is the process whereby a modem performs an initial maintenance procedure to establish
a link with the headend. The Ins column is the flapping modem’s insertion count and indicates the
number of times the RF link was abnormally reestablished. An abnormality is detected when the time
between link reestablishment attempts is less than the user-configurable parameter.
Normal modem activity follows the sequence below:
1. The initial link insertion is followed by a keepalive loop between the headend and radio modem
and is called station maintenance.
2. Power on
3. Initial maintenance
4. Station maintenance
5. Power off
When the link is broken, initial maintenance is repeated to reestablish the link:
1. Initial maintenance time T1
2. Station maintenance
3. Init maintenance at time T2
The Ins and Flap counters in the flap list are incremented whenever T2 – T1 < N, where N is the
insertion-time parameter configured by the radio flap-list insertion-time command. Default value for
this parameter is 180 seconds.
A high Ins number indicates:
•
•
Intermittent downstream sync loss
Dynamic Host Configuration Protocol (DHCP) or modem registration problems
Hit and Miss
The hit and miss columns are keepalive polling statistics between the Cisco uBR7200 series and the
radio modem. The station maintenance process occurs for every modem approximately every 25
seconds. When the headend receives a response from the modem, the event is counted as a hit. If the
headend does not receive a response from the radio modem, the event is counted as a miss. A radio
modem fails to respond either because of noise or if it is down. Modems that only log misses and zero
hits are assumed to be powered off.
Misses are not desirable, because they are usually an indication of a upstream problem; however, having
a few misses is normal. The flap count is incremented if there are M consecutive misses where, M is
configured by the radio flap miss-threshold command. The parameter value ranges from 1 to 12, with
a default of 6.
Ideally, the hit count should be much greater than the miss counts. If a modem has a hit count much
less than its miss count, then registration is failing. Noisy links cause the miss/hit ratio to deviate from
a nominal 1 percent or less. High miss counts can indicate:
•
•
Intermittent upstream, possibly due to noise
Too much or too little upstream attenuation
Cyclical
RedundancyCheck on a plant. A low count can be always be expected, but a high CRC number calls for plant
(CRC) troubleshooting. The CRC counter indicates:
This statistic tracks the CRC error counter per modem. CRC errors are usually an indication of noise

•
Intermittent upstream
Impulsive noise or interference

Flap
The flap counter indicates the number of times the modem has flapped. This counter is incremented
when one of the following events is detected:
•
Unusual modem insertion or reregistration attempts. The Flap and the Ins counters are incremented
when the modem tries to reestablish the RF link with the headend within a period of time that is
less than the user-configurable insertion interval value.
•
Abnormal miss/hit ratio. The flap counter is incremented when N consecutive misses are detected
after a hit, where N can be user-configurable with a default value of 6.
Time
Time is the time stamp indicating the last time the modem flapped. The value is based on the clock
configured on the local Cisco uBR7200 series. If no time is configured, this value is based on the current
uptime of the Cisco uBR7200 series. When a modem meets one of the three flap list criteria, the flap
counter is incremented and time is set to the current time.
