About the Hotwire ATM Line Cards
Hotwire ATM Line Cards
The Hotwire® 8335, 8355, 8365, and 8385 Asynchronous Transfer Mode (ATM)
Line Cards are circuit boards mounted in a Hotwire 8620 or 8820 GranDSLAM
(Digital Subscriber Line Access Multiplexer) 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.
1
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 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.

3
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.

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.

User Login Screen (MCP)
You can log in to the Hotwire DSL system using either a local VT100-compatible
terminal or a remote Telnet connection. However, the Hotwire DSL system
accepts only one login session at a time.
The User Login screen appears if one or more users have been defined on the
Management Communications Processor (MCP).
Enter your login ID and password. The login ID and password are case-sensitive.
If you have RADIUS Authentication, this verification may take several minutes as
each RADIUS server is contacted one at a time.
If you are denied access during a Telnet session, the session stops and an error
is logged. If you are using a console, you are automatically returned to the User
Login screen.
NOTE:
If you forget your password, contact your Technical Service Center. Have the
serial number of the MCP card available, and the service representative will
provide you with a password.

Setting Spectrum Management (Models 8355 and 8385)
The Spectrum Management screen of the Configuration branch of the Model 8355
and Model 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 (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:
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.

For the Model 8355, the following ATM Traffic Profiles screen appears:
The traffic profiles initially displayed are predefined and cannot be altered.
Table 3-1, Traffic Profile Characteristics, shows their characteristics.
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.
8335-A2-GB20-70February 20033-33
Page 56
3. Configuration
VOICE (Models 8335, 8365, 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.

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.
3-34 February 20038335-A2-GB20-70
Page 57
3. Configuration
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.

Table 5-2.Monitoring – Card Alarms (1 of 6)
Card Alarms Screen – Model 8335D-B
Displays alarms for the card and port levels. Columns on this screen represent port
numbers (01– 16).
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 GranDSLAM),
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.

DSL Port Selftest Failure – DSL port self-test results. A result code is shown for each
port: P for Pass or F for Fail.
Initialization Failure – The DSL link has failed to initialize due to one of the following:
Data Init Failure – No ACK is received form sending configuration information to the
peer ATU.
Configuration Init Failure – The peer ATU cannot support the configuration.
Protocol Init Failure – The peer ATU is incompatible.
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 GranDSLAM),
or the SCM card has been removed from the chassis.
