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.

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.

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

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.

Ethernet port
failure
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.

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.

Diagnostics → Selftest.
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.
