This chapter describes the procedures that you need to configure Profiles and Subscribers on the CDM.
Profile Configuration is used to apply a set of existing parameters to a number of similar type objects without the need for entering the same data numerous times.
The CDM has two types of profile configurations:
To add a subscriber you will need to:
A customer's connection can then be configured using the Subscriber Configuration option, refer to Subscriber Configuration .
To delete a Subscriber you will need to:
Use the DMT Profiles screen to view and configure the DMT Profiles for the NI2 object selected. The Profile Name box displays the ADSL Line configurations, each configuration contains a defined profile on the NI2. A Profile on an NI2 can be used to configure the ADSL Line.
To view the DMT Profiles screen proceed as follows:
Step 1 From the pop up menu available on a selected NI2 object, select Configure.
Step 2 From the pop up menu select DMT Profiles. The DMT Profiles screen appears:
The DMT Profiles screen contains two tabbed sections:
You can view the DMT Profiles configured on the NI2 object selected from the list box on the View/Delete tab. You also have the option to delete a selected object.A screen similar to Figure 6-1 is displayed with the following information:
This list box displays a list of the available profile names for the selected NI2 object.
When you select a Profile Name, the relevant information is retrieved, the selected Profile Name is highlighted in the Profile Name list box and the retrieved information appears in the ATUC/ATUR Parameters and DMT Parameters sections.
This field displays the profile name of the selected object.
This section displays the ATUC/ATUR Parameters associated with the profile selected. ATUC are the downstream settings, ATUR are the upstream settings. ATUC parameters displayed are specific to the physical layer parameters for the central ATUC class devices. ATUR parameters displayed are specific to the physical layer parameters for the remote ATUR class devices.
Displays the configured target signal/noise margin. This is the noise margin the modem must achieve with a BER of 10-7 or better to successfully complete initialization.
Displays the configured minimum transmit rate for \QInterleave' channels, in bps.
Displays the configured maximum transmit rate for \QInterleave' channels, in bps.
Displays the configured maximum Interleave Delay for this channel. Interleave delay defines the mapping (relative spacing) between subsequent input bytes at the interleave input and their placement in the bit stream at the interleave output.
Displays the number of symbols per codeword being used by the ATUC for downstream messages on an interleaved channel during the training sequence.
Displays the initial number of FEC redundancy bytes the ATUC appends to downstream frames transmitted over the interleaved channel during the training sequence.
This section displays the profile of the DMT Parameters associated with the selected object:
Displays the configuration profile containing enterprise-specific ADSL Line configuration information pertaining to alarms.
Displays the line-operating mode being employed by the ADSL Line. An ADSL Line uses one of two operating modes.
Displays the mode employed by the ATUC and ATUR when training against each other. One of two training modes can be employed. Standard is the default-training mode for ADSL modems.
It is a collection of managed objects defining the attributes of an ADSL Line supporting modems using the DMT Line Card. Displays whether the Trellis coding is used on the DMT Line.
Displays the negotiated overhead framing structure being used by the ATUC and ATUR.
Displays whether the bit swap is enabled or disabled. This object specifies whether the ATUC performs bitswapping. Bitswapping attempts to maintain an acceptable margin for each bin; equalizing the margin across all bins through bit reallocation, thereby maximizing error performance.
Displays the bin, which is marked by ATUC as 'from' bin, when the difference between the margin and adslATUcConfTargetSnrMgn falls below the value of the object. Bitswapping is performed by monitoring the margin measured for each bin by the transmitter.
Displays the bin which is marked by ATUC as 'to' bin, when the difference between the margin and adslATUcConfTargetSnrMgn exceeds the value of the object. Monitoring the margin measured for each bin by the transmitter performs Bitswapping.
To view the DMT Profile for other NI2 cards proceed as follows:
Step 1 Select the required Chassis and NI2 objects from the list box.
Step 2 A list of corresponding DMT profiles will be displayed in the Profile Name list box. Select the required Profile Name you wish to view.
Step 3 The related information appears in the appropriate box of the ATUC/ATUR Parameters section and the DMT Parameters section.
To delete a selected DMT Profile proceed as follows:
Step 1 Select the required Chassis and NI2 objects from the list box.
Step 2 A list of corresponding DMT profiles will be displayed in the Profile Name list box.
Step 3 Select the required DMT profile configuration profile you wish to delete.
Step 4 The related information appears in the appropriate box of the ATUC/ATUR Parameters section and the DMT Parameters section.
Step 5 Click the DELETE button. A Delete Profile? confirmation screen appears.
Step 6 Click YES to proceed or NO to cancel.
You can add a new DMT profile for the NI2 object selected from the list box. Only one NI2 object can be selected at any one time.
The Add tab has three sections:
This box displays the profile name of the selected object.
Configure the following ATUC/ATUR parameters for a selected NI2 object:
Enter the value in this field for the ATUC/ATUR Parameter, Configured Target Signal/Noise Margin. This is the Noise Margin the modem must achieve with a BER of 10-7 or better to successfully complete initialization. If the Noise Margin is above this the modem should attempt to reduce its power output to optimize its operation. If the noise margin falls below this level, the modem should attempt to increase its power output. If that is not possible the modem will attempt to re-initialize or shut down.
Enter the value in this field for the ATUC/ATUR Parameter, Configured Minimum Transmit rate for \QInterleave' channels, in bps.
Enter the value in this field for the ATUC/ATUR Parameter, Configured Maximum Transmit rate for \QInterleave' channels, in bps.
Enter the value in this field for the ATUC/ATUR Parameter, Configured maximum Interleave Delay for this channel. Interleave delay applies only to the interleave channel and defines the mapping (relative spacing) between subsequent input bytes at the interleaver input and their placement in the bit stream at the interleaver output. Larger numbers provide greater separation between consecutive input bytes in the output bit stream allowing for improved impulse noise immunity at the expense of payload latency.
A collection of managed objects defining the enterprise-specific line configuration information associated with one or more ADSL ATU class devices implementing the DMT Line code. A configuration profile containing enterprise-specific ADSL DMT Line configuration information. Select the required option, either the Echo Cancel or the Frequency Division Multiplex, from the combo box as follows:
Enter the operating mode in this data entry box. This object specifies the line-operating mode being employed by the ADSL Line. An ADSL Line uses one of two operating modes:
Enter the training mode in this data entry box. This object specifies the mode employed by the ATUC and ATUR when training against each other. One of two training modes can be employed:
Select the Trellis encoder from the options, that is: enable or disable from the combo box. Use of trellis coding is determined at line initialization with C-MSGS1 and R-MSGS1 exchanges and will not change until the line is re-initialized. Defines the operational mode of the DMT ADSL transceiver. This is configured in the C-MSG1 and C-MSG-RA exchanges.
Enter the overhead framing value in this data entry box. Two types of ADSL framing are possible: full overhead and reduced overhead. Each of these options has two versions of full overhead and two versions of reduced overhead. Table 6-1 defines the four framing structures:
| structure0 | Full overhead framing with asynchronous bit-to-modem timing (enabled synchronization control mechanism) |
| structure1 | Full overhead framing with synchronous bit-to-modem timing (disabled synchronization control mechanism) |
| structure2 | Reduced overhead framing with separate fast and sync bytes in fast and interleaved latency buffers respectively (64 KBPS framing overhead) |
| structure3 | Reduced overhead framing with merged fast and sync byte, using either the fast or interleaved latency buffers (32 kbps framing overhead) |
During the training sequence, the ATUC indicates the highest framing structure number it supports. This implies that if the ATUC supports framing structure k, it also supports all framing structures 0 to k-1. If during the training sequence the ATUR indicates a lower framing structure than that specified by the ATUC, the ATUC shall fall back to the framing structure number indicated by the ATUR.
Management requirements drive the determination of overhead, full or reduced. Full overhead provides more bandwidth to the EOC channel, enabling higher polling rates. However, reduced overhead provides enough bandwidth to satisfy typical applications. If an ADSL Line is supporting an ATM link, then a structure must be chosen that disable synchronization control. If an ADSL Line is supporting an STM link, and the ADSL Line interface has a clock tightly coupled to the stratum clock, then synchronization control is not necessary.
If an ADSL Line is supporting an STM link, and the ADSL Line interface is driven by a clock that has no relationship with the stratum clock, then a structure that enables synchronization control is necessary.
Enter the bit swaps value, either TRUE or FALSE, in this data entry box. This object specifies whether the ATUC performs bitswapping.
Bitswapping attempts to maintain an acceptable margin for each bin equalizing the margin across all bins through bit reallocation, thereby maximizing error performance. The ATUC performs bitswapping by monitoring the margin measured for each bin by the transmitter:
The ATUC attempts to equalize the margin across the bins by swapping bits out of bins marked 'from' into bins marked 'to'. When the ATUC swaps a bit out of bin, it decreases its b (i). Thus, the bin constellation is smaller which increases its margin. When the ATUC swaps a bit into a bin, it increases its b (i). Thus, the bin constellation is larger, which decreases its margin.
In addition, the ATUR may optionally implement its own monitoring capability. The ATUR uses this information to request the ATUC to perform bitswapping. When this object is 'true', the ATUC must be prepared to accept and properly handle bitswap requests from the ATUR. While bitswapping has its obvious advantages, bitswapping can have undesirable side effects. It can introduce errors on lines prone to impulse noise. In this case, it may be desirable to disable bitswapping.
Enter the bits that are swapped out of the bin.
Enter the bits that are swapped into the bin.
Enter the name of the new profile in this data entry box.
To add a DMT profile proceed as follows:
Step 1 Select the required NI2 object from the list box.
Step 2 Enter the values into the appropriate boxes.
Step 3 Enter the name of the new profile in the New Line Profile Name box.

Subtending is the process of connecting two 6260 NI2 cards to support more subscribers under the same trunk port. The subtending feature provides a mechanism to link a number of shelves into one network trunk port. A maximum of 12 nodes can be subtended from the root node but at any level the number of NI2 cards should not exceed more than 6 in a series.
Subtending requires connection of the ATM ports in the NI2 of one CDM to another CDM's NI2.
This feature allows improved per-port costs for service providers by reducing the number of ports required in an aggregator or backhaul network when multiple DSLAMs are installed in one location.
