About the ATM Line Cards

Hotwire ATM Line Cards

The Hotwire® 8335, 8355, 8365, 8375, and 8385 Asynchronous Transfer Mode (ATM) Line Cards are circuit boards mounted in an 8620 or 8820 Broadband Loop Carrier (BLC) and used to transport ATM cells at high speeds over a single twisted-pair connection.

 Model 8335 supports Symmetric Digital Subscriber Line (SDSL). It can be set

to AutoBaud to the highest rate the loop can support, or to use a fixed line rate from 144 to 2320 kbps.

 Model 8355 supports ReachDSL

. It automatically adjusts to the highest rate

the loop can support, from 32 to 2176 kbps.

 Model 8365 supports Asymmetric Digital Subscriber Line (ADSL). It can be

set to adapt to the line conditions at startup, or set to the following fixed rates depending on line code:

— G.dmt and ANSI T1.413: 32 to 8000 kbps downstream and 32 to 832 kbps

upstream.

— G.lite: 64 to 3008 kbps downstream and 32 to 512 kbps upstream.

 Model 8375 supports ReachDSL+, giving it the capabilities of the Models 8355

and 8365 in one card.

 Model 8385 supports Single-pair High-speed Digital Subscriber Line

(SHDSL). It can be set to adapt to the line conditions at startup, or set to a fixed line rate from 200 to 2312 kbps.

Part of Paradyne’s Hotwire Connected™ program, the cards interoperate with third-party DSL endpoints providing end users with the ability to select the best equipment to fit their application. The new line cards also integrate support for multiple DSL services on a single card.

Menus and Screens

Menu and Screen Formats

The Hotwire BLC has an ASCII-based menu- and screen-driven user interface system that enables the user to configure and monitor the Hotwire cards. This section describes the components of a typical Hotwire menu and screen.

A typical Hotwire menu format is shown below:

1. Menu Title is the top line of the menu window that displays the title of the menu or submenu.

2. Menu List is the portion of the menu window that displays the list of menu options. When selected (by using the up and down arrow keys to move the cursor position), a menu option displays a submenu window.

3. Letter Navigation Keys are provided within a menu list. These keys provide an alternative method for selecting menu items.

For example, from the Hotwire – DSL menu illustrated above, you can press the A key to select the Configuration menu item. The Configuration menu appears. You can then press the A key to select the Card Status menu item, and subsequently the Card Info menu item.

Some menu items not active for this product are displayed as placeholders in the menu lists so that letter navigation keys are the same for all related products.

2. Menus and Screens

2-2 March 2005 8335-A2-GB20-A0

Components of a Hotwire Screen

A typical Hotwire screen looks like this:

1. System Header Line is the top right line of the screen. This line contains two fields of system login information:

— The first field displays a user-defined chassis or individual card name. If

you have not defined the system name, <no name> appears.

— The second field displays the previous remote or local login depending on

what is currently displayed in the middle field (such as the current login). If the current login is local, the last field displays the previous remote login. If the current login is remote, the last field displays the previous local login.

2. Display Area is the main body of the screen. This area contains the screen name in a “tab” at the upper left, and fields displaying data and/or requiring input. The input values themselves are entered in the Input Line at the bottom of the screen.

3. Input Line is in the lower area of the screen. This area displays prompts after which you enter values for the field highlighted in the Display Area.

If a field has predefined permitted values, you need only type enough of a value to distinguish it from other permitted values. For example, if the Behavior field has a value of Fixed or AutoBaud, you need only type f or a, respectively, and press Enter, to select a value.

Line 2: Slot 02: 8335: D D D D D D D D D D D D D D D D Line 3: Slot 02: 8335: Press ? For Help

Naming Conventions for Ports and Interfaces

Special naming conventions exist for the Port Name and Interface Name fields.

 Port Name – Identifies a physical port. It consists of a family name (dsl for a

DSL card), and a port number. The port number can range from 1 to the number of ports on the card. For example: dsl12.

 Interface Name – Identifies a logical connection. It consists of a family name

and a port number (same as the port name), followed by a number identifying a logical interface on the port. Currently the interface number is limited to 1. For example: dsl12:1.

Setting Spectrum Management (Models 8355, 8375, and 8385)

The Spectrum Management screen of the Configuration branch of the Models 8355, 8375 and 8385 line card (menu sequence A-A-G) sets the unique regional operational parameters to use for this card. For the Model 8385, the selections differ depending on whether you are using the card in Notrh American (Annex A) or European (Annex B) networks.

The purpose of Spectrum Management is to facilitate a reasonable spectral environment for the coexistence of multiple technologies in the loop plant with an acceptable level of crosstalk between them. In some countries, the DSL service provider must meet the spectrum management specification of that country. For example, in the United Kingdom, it is a requirement that the product comply with OFTel PSD mask for the loop length requested (extra short, short, medium or long). Support for this requirement is provided by enabling the Spectrum Management option on the Spectrum Management screen (A-A-G), and properly setting the Line Length and EWL options on the Port Configuration screen (A-B-B).

NOTE:

Settings on the Spectrum Management screen affect the choices available for the DSL Port Configuration screen (menu sequence A-B-B). See DSL Port

Configuration – Model 8355 on page 3-11 or DSL Port Configuration – Model 8385 on page 3-24 for more information.

To enter DSL Port Configuration screen information for the Model 8335:

1. Select an Action:

Edit – To edit fields on the screen.

Reset – To enable the port and cause the DSL line to retrain.

2. Select the Port Name of the port to be configured or reset (dsl1 through dsl16).

3. For Edit mode, position the cursor in the field you wish to modify. Type the value you want and press Enter.

NOTE:

Fixed rate and autobaud are the two methods used for synchronizing the DSL line between the central office equipment and the customer premises equipment.

— Fixed rate is used for applications that cannot tolerate having the

speed of the DSL link change (for example, a TDM application). Fixed rate is the fastest method, and it always trains at the same speed. However, depending on line conditions, training may not occur without errors.

— Autobaud is used for applications that can tolerate having the speed of

the DSL link change (for example, IP traffic). The autobaud algorithm sets the DSL link to the highest error-free speed. Autobaud may try several speeds to find the best rate for the line conditions. As a result, autobaud usually takes longer to train than fixed rate. The training time for autobaud will vary with the line conditions, with some line conditions causing the algorithm to take several minutes.

Regardless of which training mode is used, both DSL units must be set to the same mode.

 AUTOBAUD (Model 8335 only): This profile allows for packet traffic to the

endpoint that is used during training of the DSL link. It is also used to retrieve statistics from the endpoint during normal operation. There is no PCR (Peak Cell Rate) associated with the profile, since there is no policing.

 IP MGT (Models 8335 and 8385 only): This profile is for a management path

to the endpoint that is used by the Network Access Provider to manage the endpoint. This traffic could include SNMP or Telnet traffic. This connection is not policed.

 PACKET: This profile allows packet data traffic up to the maximum that the

DSL link can handle. There is no policing associated with this connection. The priority mechanism will ensure that the voice traffic to be sent ahead of the data traffic. This is the only default profile for the Model 8355.

 VOICE (Models 8335, 8365, 8375, and 8385 only): This profile allocates

enough bandwidth for one voice call (approximately 80 kbps). If more than one voice call is placed on the connection using this profile, then the cells will be tagged (CLP bit set). This profile is policed to 188 cells/sec (enough for one phone call).

Some numeric values on the ATM Traffic Profiles screen represent cells per second. An ATM cell is 53 bytes (48 bytes of data plus 5 bytes of overhead), or 424 bits. Conversion guidelines are listed in Table 3-2, Conversion Guidelines.

A voice circuit typically requires 80

kbps, which is 188 cells per second. ATM cells

are 53 bytes in length (a 5-byte header and 48 bytes for payload). After allowing 4 bytes for the AAL2 overhead, you have approximately 44 bytes available for data. Therefore, the total overhead is 53/44. For a 64 kbps stream, this results in

77.1 kbps (64 x 53/44). The 80

kbps allows extra bandwidth for additional inband

signaling.

The ATM line cards implement Usage Parameter Control (otherwise known as policing) as described in the ATM Forum’s Traffic Management Specification 4.1 (AF-TM-0121.000). According to this specification, traffic contracts for the two VBR ATM service categories (rt-VBR and nrt-VBR) include traffic parameters for Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR). Policing is implemented using the recommended dual Generic Cell Rate Algorithm (GCRA) functions.

A problem arises when configuring the two GCRA functions as recommended by TM 4.1 if you specify VBR service and set PCR and SCR to the same value (PCR=SCR). The Maximum Burst Size (MBS) parameter then becomes irrelevant and both GCRA functions end up with the same increment and limit values. This occurs because in every available VBR policing configuration, the action taken for nonconforming cells by the first GCRA function is a superset (more severe or at least as severe as) the action taken by the second GCRA function; the second GCRA function has no effect. Therefore, if you specify a VBR service category and set PCR equal to SCR, the line card uses a single GCRA with the increment based on PCR and limit based on CDVT. The line card ensures conformance only to the PCR value within the CDVT range (specified or default). The MBS parameter has no effect.

Procedure

Major Alarms:

Selftest – Shown as Pass or Fail.

ATM Bus Failure – If ALARM appears on this line, there has been a Loss Of Clock (LOC)

because the line card is unable to communicate with the SCM. This could be because the chassis does not support the ATM bus (the chassis is not an 8620 or 8820 BLC), or the SCM card has been removed from the chassis.

DSL Port Selftest Fail – DSL port self-test results. A result code is shown for each port: P for Pass or F for Fail.

Minor Alarms:

Config Error – If ALARM appears on this line, the card has detected a checksum error in

the memory where the configuration is stored.

Loss of Cell Delineation – If a loss of cell delineation has been detected on the port, an A (for Alarm) appears in the column for that port.

Loss of Signal – If a loss of signal has been detected on the port, an A (for Alarm) appears in the column for that port.

CAC Exceeded – The DSL line rate has dropped below the traffic contract. The traffic contract has exceeded the available bandwidth making the contract invalid.
