Hotwire DSLAM System  
Description  
1
What is the Hotwire DSLAM?  
The Hotwiret Digital Subscriber Line Access Multiplexer (DSLAM) is a DSL  
platform that houses a Management Communications Controller (MCC) card and  
up to 18 DSL cards. These can be 8310 Multiple Virtual Lines (MVLt) cards,  
8510 Rate Adaptive Digital Subscriber Line (RADSL) cards, or a combination of  
both.  
NOTE:  
All references to DSL cards refer to both RADSL and MVL cards, unless  
specifically noted otherwise.  
The DSLAM interoperates with two types of Hotwire Service Nodes  
(SNs)/endpoints to deliver applications at high speeds in support of packet  
services over a Digital Subscriber Line (DSL) link.  
H
H
The 8310 MVL card interoperates with the Hotwire 6310 MVL modem.  
The 8510 DSL card interoperates with the Hotwire 5620 SN.  
The DSLAM is a set of central site products that terminate and consolidate packet  
data traffic from many customers in a serving area. It then forwards the traffic to  
one or more network access provider networks.  
High-speed Internet and intranet access is achieved via a bridge from the DSL  
links and then concentrated for efficient forwarding to backbone networks. By  
enabling very high speeds using DSL technology and concentrating Internet  
Protocol (IP) traffic, greater performance is realized.  
In addition, the Hotwire DSLAM with an endpoint such as a 6310 MVL modem  
and 5620 SN can co-exist with Plain Old Telephone Service (POTS) over the  
same copper telephone line, providing simultaneous usage of POTS and digital  
applications. That is, the optional POTS splitters (Hotwire 5020 Central Office  
POTS Splitter and Hotwire 5030 or 5038 Customer Premises POTS Splitter)  
allow simultaneous voice and data connections over a standard telephone line.

The Hotwire DSLAM system consists of the following components:  
H
Hotwire DSLAM chassis  
There are two types of chassis:  
— The Hotwire 8600 DSLAM chassis is an independent, standalone  
system. The stackable design provides for up to six chassis to share  
management access through a single MCC card, which in turn, allows an  
additional slot for a DSL card in each of up to five additional chassis.

One Management Communications Controller (MCC) card  
The chassis requires one MCC card, which is a processor card that  
administers and provides diagnostic connectivity to the DSL cards. It acts as  
a mid-level manager and works in conjunction with a Simple Network  
Management Protocol (SNMP) system, such as Paradyne’s OpenLanet  
DCE Manager for HP OpenView, via its LAN port. It gathers operational  
status for each of the DSL cards and responds to the SNMP requests. It also  
has a serial port for a local user interface to the DSLAM.  
For more information about the Hotwire MCC card, see the Hotwire  
Management Communications Controller (MCC) Card, IP Conservative,  
User’s Guide.  
At least one Digital Subscriber Line (DSL) or Multiple Virtual Lines  
(MVL) card  
The chassis requires at least one DSL or MVL card, which is a circuit card  
that contains four RADSL or MVL modem ports, an Ethernet interface to the  
Internet Service Provider (ISP), and a processor/packet forwarder. The  
processor/packet forwarder controls the modems and forwards the packet  
traffic via the Ethernet and DSL or MVL interfaces. When the 8600 DSLAM  
chassis is fully populated, it provides a total of 68 RADSL or MVL modem  
ports. When the 8800 DSLAM chassis is fully populated, it provides a total of  
72 RADSL or MVL modem ports.

Selftest  
D-A  
Displays the results of the last disruptive selftest of the DSL card. This selftest is only  
performed on power up of the system or a reset of the card. Each subsystem  
(processors, memory, and interfaces) reports pass or fail. If all subsystems pass, the  
card has passed selftest. If a subsystem fails, reset or replace the card.  
You can determine when the selftest occurred by reading the elapsed time since the last  
reset on the card.  
Alarms (Card Alarms)  
D-B  
Displays all active card alarm conditions. Major alarms include Selftest failure,  
Processor failure (sanity timer), and DSL or Ethernet port failures. Minor alarms include  
Config Error (configuration has been corrupted) and threshold exceed for DSL margin or  
Link Down events.  
DSL Packet Echo Test  
D-C  
Gives the user the ability to conduct a nondisruptive packet test between the DSL card  
and Hotwire SN endpoint. Test packets are sent to the SN at 10 percent of the line rate  
and echoed back to this card, where they are counted and checked for errors. The  
running time of the test can be specified and the test will continue until the specified  
time has elapsed or the test is stopped.  
Results include packets sent, valid packets received, errored packets received, errored  
seconds, and elapsed time of the test.

Diagnostics and Troubleshooting  
Checking Alarms  
If the Card Selection screen indicates that a Major or Minor Alarm is on a card,  
follow the menu sequence Diagnostics Alarms (D-B) to determine the cause of  
the alarm.  
NOTE:  
If a DSL card does not appear on the Card Selection screen because the  
MCC card can no longer communicate with it, the MCC card will generate a  
major alarm. You should go to the MCC’s Monitor Card Status Syslog  
(A-A-C) and view the event on its system log.  
Major Alarms  
Use Table 7-2 to determine the appropriate action to take for each Major Alarm.  
Table 7-2. Major Alarms (1 of 2)  
Failure Type  
Action  
Selftest failure 1. Check the Selftest Results display by following the menu sequence:  
Diagnostics Selftest.  
2. Do another Selftest (Reset) and check results.  
– If the results are normal, the problem was transient. Log the  
results.  
– If the results are the same as the first selftest, the card should be  
replaced. If only one port on a DSL card is bad, that port can be  
disabled. You may continue to use the card until it is convenient  
to replace it.

1. Check cable connections to the DSLAM.  
– If cables are terminated properly, go to Step 2.  
– If cables are not terminated properly, terminate them correctly.  
2. Check cable connections to the Hub or Ethernet switch.  
– If cables are terminated properly, go to Step 3.  
– If cables are not terminated properly, terminate them correctly.  
3. Check the Activity/Status LED at the Ethernet Hub or Switch.  
– If Activity/Status LED does not indicate a problem, go to Step 4.  
– If Activity/Status LED indicates a problem, take appropriate  
action.  
4. Disconnect the Ethernet cable and replace it with a working cable  
from a spare port on the Hub.  
– If the replacement cable works, the original is bad and should be  
permanently replaced.  
– If the replacement cable does not work, reconnect the original  
cable and go to Step 5.  
5. Move the DSL card and cable to another (spare) slot.  
– If this solves the problem, the connector or interface panel  
connections for the original slot are bad. Schedule maintenance  
for the chassis and try to use the spare slot temporarily.  
– If this does not solve the problem, the DSL card is probably bad  
and should be replaced.

replaced. If only one port on a DSL card is bad, that port can be  
disabled. You may continue to use the card until it is convenient  
to replace it.  
DSL card not  
responding  
1. Check to see if the lights are out on the card.  
– Plug the card into an empty slot to see if it responds. If not, the  
card is bad and needs to be replaced.  
(LEDs on card  
are out or MCC  
is showing an  
alarm.)  
– If the card responds in a different slot, the slot connector may be  
bad. Call your service representative.  
2. Check to see if the lights are on, but not responding.  
– Pull the card out and plug it in again.  
– Reset the card from the MCC or DSL Main Menu.  
– Go to the MCC Main Menu and clear NVRAM.  
– Replace the card.

2. Do another Selftest (Reset) and check results.  
– If the results are normal, the problem was transient. Log the  
results.  
– If Selftest results still show configuration corruption, there is a card  
problem. The card’s nonvolatile RAM should be erased and the  
configuration reentered. Perform a configuration download.  
– If the configuration has not been saved, use reset and erase  
NVRAM to force the card to the factory default. Enter the basic  
default route to the MCC and reconfigure the card manually.
