Ground Connection
This section provides the grounding rule for the Model 3124. All remote system sites must be properly
grounded for optimum system performance.
In Central Office. There should be a CO GND that is adequately grounded. If the measured resistance from
the grounding screw (on the rear panel of the DSLAM, refer to Figure 1-4) to CO GND is less than 5 Ohm,
then it can be assumed that the system is well grounded. If the measured resistance is larger than 5 Ohm, it is
recommended to connect the grounding screw to CO GND using #14 or #12 AWG wire gauge conductor.
In Remote Cabinet. The Model 3124 should be grounded by connecting a #14 or #12 AWG conductor
between the grounding screw (on the rear panel of the DSLAM, refer to Figure 1-4) and the earth ground or
main grounding bar. The resistance between the chassis and the grounding bar should be less than 25 Ohm.

Software Configuration Overview
Note
For more detailed software configuration instructions, refer to the
Model 3124 Administrator’s Reference Guide available online at
www.patton.com/manuals/3124-arg.pdf and the Model 3124 Com
-
mand Line Reference Guide available online at www.pat-
ton.com/manuals/3124-cli.pdf.
The software architecture of the Model 3124 is shown in the figure below. It can be divided into three layers:
the management layer, the OAM&P layer, and the firmware layer.
As in the figure, CLI shell, SNMP agent, and WEB server are in the top-most layer (management layer) of the
system software and offering OAM&P function of the DSLAM based on the conceptual management features
as follows:
• Configuration Management
• Performance Management
• Fault Management
Software Configuration Overview 33
Figure 33. Management Software Model
Model 3124 User Manual 3 • Configuration
The Model 3124 uses flash memory as the database (DB) to store system configuration parameters. The firmware layer includes ADSL drivers, Memory and I/O control, etc.
Features of the Management Interface include:
• Support CLI, SNMP (v1, v2c), and web-based GUI management interface through in-band channels
• Support up to 10 CLI sessions at the same time
• The in-band management connection of the system is the highest priority of all supported in-band traffic
categories
• Support Telnet interface for remote operators to login system operating console
• Support up to 32 configurable SNMP trap destinations and allow the SNMP traps to be sent to any speci-
fied SNMP aware device, for instance, Network management center
Configuration Management
The configuration management contains the following aspects:
• System Setup, such as setup for management IP address/net mask, GBE interface (including to enable/dis-
able and query the administrative/operational status of the trunk port), line port (including to enable/disable/reset ADSL port, query the administrative/operational status of the port, and bind profiles on a per
port basis), CLI session and timeout, Cluster, SNTP, IP routes, and user administration (including login
authorization and provides three security levels).
• Bridge Configuration (refer to “Bridge Configuration” on page 34)
• ADSL Configuration (see “refer to “ADSL Configuration” on page 35)
• ATM traffic management
• SNMP setup
The configuration management provides detecting and reporting to the operators through SNMP Trap for all
memory updates reflecting changes in the system configuration. It also provides logging the changes in the
operational state and making this information available (on-demand) to the operators over the operation inter
face. The system contains a database (DB) to store all the provisioning data so that the configuration can be
restored in re-booting. Authorized operators can query the DB to obtain configuration data.
Bridge Configuration
The bridge configuration of the Model 3124 includes the following aspects:
• Interface setup
• VLAN configuration: static VLAN, protocol based VLAN, VLAN translation, and IP/MAC anti-spoofing.
• Access Control: Filtering, VLAN priority remark, rate limit, and priority queue mapping.
• Forwarding database
• DSL Line Identify
• IGMP configuration
-
• IPoA configuration
Software Configuration Overview 34
Model 3124 User Manual 3 • Configuration
ADSL Configuration
Configuration for an ADSLx user port is provisioned by the parameter set, which is a group of attributes that
determine the user port behaviors; and we call it as a profile. The Model 3124 provides a profile-based provi
sioning per the definition of ITUT G997.1 and RFC 2662 for ADSL line configuration data and a mechanism
to associate the ADSL port to these profiles. One or more ADSL lines may be configured to share parameters
of a single profile.
The ADSL profiles of Model 3124 include:
• Service Profile
The parameters include Rate adaptive mode selection, Min/max/planned bit rate, Interleaving Max delay,
and Minimum impulse noise protection.
• Spectrum Profile
The parameters include the Power management setting, Min/max/target noise margin, allowed ADSL
modes of operation, Carrier mask, RFI band data, Maximum nominal aggregate transmit power, Maximum
PSD level, PSD shape (for ADSL2+), Power back off initiation, and Maximum aggregate receive power.
• TCA Profile
The parameters include ESs, SESs, UASs for interval and day PM, and LOS, LOF, LOPWR, LOL, Error
Frame for interval PM only.
The system provides up to 120 Service profiles and Spectrum profiles respectively, and provides up to 16 TCA
profiles. One of the profiles is a fix default that cannot be modified; users are allowed to create, and edit the
other profiles. Each profile contains a parameter set for downstream and upstream direction respectively. Users
can also observe the actual values of these parameters through CLI, Web-GUI, or EMS.
The ADSL configuration also includes the function for user to query the line status, the physical layer status,
and the channel interface status for ATU-C and ATU-R. The status information includes the attenuation rate,
actual net data rate, the line attenuation, SNR margin, transmission power, actual interleaving delay, channel
characteristics per subcarrier, quiet line noise PSD, …etc.
Performance Management
Performance management supports performance monitoring by collecting and thresholding performance
parameter counters against 15-miniute intervals for each interface and module respectively. Users can query the
data of these parameters through CLI, Web-GUI, or EMS.
Performance statistics include the following:
1. Statistics for current interval:
A real-time aspect contains the reflection of the current value situation before the new interval. The current value includes values of current 15-min interval and current 1-day interval.
2. Statistics history at 15-minute basis:
The system stores previous 96 statistics of PM parameters at 15-min interval for retrieving.
3. Statistics history at 1-day basis:
The system stores previous 1 statistics of PM parameters at 1-day interval for retrieving.
Most of the performance parameter thresholds are user-programmable. The Model 3124 uses a threshold
crossing alert (TCA) to notify the management system when one of the counts during a measurement interval
exceeds its threshold.
Software Configuration Overview 35
Model 3124 User Manual 3 • Configuration
The TCA contains the following information:
• Specific interface involved
• Error condition identifying the measurement type
• Value of the parameter
• Occurrence date and time of the event
The performance management also provides the traffic counter including transmitted packets, error packets
and discarded packets for each interface (network and subscriber interface) and ATM cell counter in both
transmit and receive direction. Users can observe these data through CLI, Web-GUI, or EMS.

Fault Management
Fault management is conceptually partitioned into two levels: the system top level, and interface-specific level.
Both levels are alarm-level configurable and can be Major and Minor. All the alarms are mask-able.
Fault management provides the alarm output through hardware output interface (on the system front panel)
and visible indicator (LED). The alarm/status indications are automatically generated as a result of certain
events/conditions. The Model 3124 supports query of all current alarm status. It is also able to keep 256
records of historical alarms and events respectively.
The Model 3124 provides the ability to group alarms in a hierarchical alarm presentation scheme. Alarms of
the same rank can exist at the same time. A lower-ranking alarm will be demoted if a higher-ranking alarm is
raised for the same object. For example, if a far-end LOS is raised on a circuit and then a far-end LPR is raised
on the circuit, the LPR alarm stands and the LOS closes. The alarm hierarchy used in the Model 3124 system
is shown in the following table:
Table 15. Model 3124 Alarm Hierarchy
Priority Alarm Type
Highest all activation failures (ADSL_COMMF_FE or ADSL_NOPEER_FE)
—
—
Lowest near-end LOF or far-end LOF (near-end and far-end are independent;
far-end LPR
near-end LOS or far-end LOS
for example, FE-LOS does not restrain NE-LOF)
Note
LOM, LCD, and NCD are not included in the alarm hierarchy;
they’re treated independently.
Note
The PM counters LPR, LOS, and LOF follow the alarm hierarchy
rule. When these alarms exist at the same time, only the PM counter
of a higher-ranking alarm will count (the PM counters of other lowerranking alarms will not).
System Alarms
The Model 3124 provides the following System alarms:
• Fan Failure Alarm
• Above Temperature
• Below Temperature
• Self-test Fail
• DSP Fail - you can see which DSP chip is fail from the user interface (Web GUI, CLI, etc.). There is a
number 1 ~ 4 in the alarm message/description corresponding to the DSP chip 1 ~ chip 4
Software Configuration Overview 39
Model 3124 User Manual 3 • Configuration
ADSL Alarms
The Model 3124 provides the following ADSL alarms:
• LOS (Loss of Signal) -Near End/Far End
• LOF (Loss of Frame) -Near End/Far End
• LOM (Loss of Margin) -Near End/Far End
• LCD (Loss of Cell Delineation) -Near End/Far End
• NCD (No Cell Delineation) -Near End/Far End
• LOPWR (Loss of Power) -Far End
• COMMF: Unable to communicate with peer modem -Far End
• NOPEER: No peer present – Far End
Loopback Testing
The Model 3124 supports ATM and ADSL loop diagnostics.
• ATM:
The system provides F5 end-to-end or segment loopback.
• ADSL:
The system provides Dual Ended Loop Testing (DELT) for each ADSL line on a per port basis, according
to the definition per section 8.12.3 of ITUT G992.3.
The following test parameters are supported:
- Channel Characteristics Function H(f) per subcarrier (CCF-ps),
- Quiet Line Noise PSD QLN(f) per subcarrier (QLN-ps),
- Signal-to-Noise Ratio SNR(f) per subcarrier (SNR-ps),
- Line Attenuation (LATN),
- Signal Attenuation (SATN),
- Signal-to-Noise Ratio Margin (SNRM),
- Attainable Net Data Rate (ATTNDR),
- Far-end Actual Aggregate Transmit Power (ACTATP),
- Near-End Actual Aggregate Transmit Power (ACTATP).

Model 3124 User Manual 3 • Configuration
Cluster Feature
The Model 3124 supports Cluster feature that can make a group of NEs (network elements) work together as
a single NE from the management point of view. Operators can manage the NEs in a cluster, called cluster
nodes, via the same single IP address in terms of CLI, Web-based GUI or SNMP based management inter
faces. The Model 3124 currently provides cluster feature that a cluster can include up to four cluster members
(NEs). There are one Master and the other members are all Slaves in a cluster. The Master works as a gateway
of the Slaves, and it also can forward CLI/Web/SNMP commands to the destination Slave. The Slaves can exe
cute the commands and respond to the Master.
It uses star topology for conducting a Clustering Management group.
-
Figure 34. Cluster network topology - Star
Before you group a Master and a Slave IPDSLAM, some parameters need to be well configured:
1. Cluster domain name: The group name for a cluster must be the same on Master and Slave.
2. Cluster IP address: IP address to be used for remote management when Master and Slave are grouped
together.
3. NE cluster name: A name to identify Master or Slave.
4. Set private IP address on in-band port for both Master and Slave IPDSLAM. The private IP is used for
communication between Master and Slave. The management center actually uses Cluster IP address for
remote management.
5. Master and Slave need to be configured with same management VLAN.
6. The default gateway should be configured to the router that is aware how to route management traffic to
Management Center of the management network. The setting of Cluster default gateway should be the
same between Master and Slave.

Warranty coverage
Our products are under warranty to be free from defects, and we will, at our option, repair or replace the product should it fail within one year from the first date of shipment. Our warranty is limited to defects in workmanship or materials, and does not cover customer damage, lightning or power surge damage, abuse, or
unauthorized modification.
Out-of-warranty service
Patton services what we sell, no matter how you acquired it, including malfunctioning products that are no
longer under warranty. Our products have a flat fee for repairs. Units damaged by lightning or other catastro
phes may require replacement.
Returns for credit
Customer satisfaction is important to us, therefore any product may be returned with authorization within 30
