About This Document
This guide is written for administrators and technicians who install devices at the
central office (CO) or at a Network Service Provider (NSP) location adjacent to the CO.
It should be used in conjunction with the appropriate Hotwire DSL card User’s Guide or
Network Configuration Guide, which describes how to plan the data networks
surrounding the DSLAM and specific DSL cards.
To install the customer premises (CP) portion of the Hotwire 8610 DSLAM, refer to the
appropriate Hotwire Remote Termination Unit (RTU) Customer Premises Installation
Instructions and Hotwire POTS Splitter Customer Premises Installation Instructions.
What is the Hotwire 8610 DSLAM?

The 8610 DSLAM accepts the following types of cards:
HManagement Control Processor (MCP). This 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 an SNMP network management system,
such as 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
local terminal access.
HMVL, RADSL and DSL cards. These cards provide a processor and an Ethernet
interface to the NSP. The processor controls the modems and forwards the packet
traffic to and from the Ethernet and DSL interfaces. Models include:
— 8310 4-port and 8312 12-port Multiple Virtual Lines (MVL) cards that
interoperate with the Hotwire 6310 modem.
— 8510 Rate Adaptive Digital Subscriber Line (RADSL) card that interoperates
with the 5620 Remote Termination Unit (RTU).
— 8540 Digital Subscriber Line (DSL) card that interoperates with either the 5216
or 5246 Remote Termination Unit (RTU).
— 8546 DSL card that interoperates with the 5446 RTU.
HMultirate High-bit-rate Digital Subscriber Line (M/HDSL) card.
HMultirate Symmetric Digital Subscriber Line (M/SDSL) card.
NOTE:
RADSL, MVL, M/HDSL and M/SDSL cards are generically referred to as DSL
cards in this document.
Hotwire 8610 DSLAM Features
The Hotwire 8610 DSLAM chassis has the following features:
HPower Redundancy
Two versions of the Hotwire 8610 DSLAM chassis are available:
— ac power
— dc power
The ac version can also be connected to a dc source to provide power
redundancy. When using the dc version, two separate dc sources may be
employed to provide power redundancy. If one power source fails, the other source
provides all of the power needed by the system. This is done automatically without
system disruption.
The dc version requires a source of –48 Vdc, while the ac version will operate from
100 to 250 volts ac, 50 to 60 Hz.

4
HStackable Chassis for DSL Access Growth
Each chassis is an independent, standalone system. The 8610 and 8600 chassis
are interoperable in a stack. The stackable design provides for six systems to
share management access through a single MCP card (for 8610) or MCC card (for
8600) which, in turn, allows an additional slot for a DSL card in each of up to five
additional systems. In a stacked configuration, the first or base chassis is equipped
with an MCP/MCC card in Slot 1 leaving Slots 2 and 3 available for up to two DSL
cards.
Each additional system will accept up to three DSL cards.
A Hotwire 8610 or 8600 DSLAM chassis can be added or removed from the stack
without disrupting data service to the other items in the stack. However,
management service will be disrupted.
The base system is connected to additional systems by connecting the 8-pin
modular expansion cable provided from the OUT port of the base chassis to the IN
port of the next chassis in the stack.
HHot Swappable Cards
The MCP and DSL cards can be installed and removed from the Hotwire 8610
DSLAM chassis without service disruption. You can replace a card without
powering down the chassis and disrupting service to the other cards.
HPrimary Network Management Support via SNMP
SNMP management of the DSL cards is accomplished over a single Ethernet
connection to the MCP card from a Network Management System (NMS) (such as
Paradyne’s DCE Manager for HP OpenView). The MCP card gathers all
management information for each of the DSL cards and responds to the SNMP
requests on behalf of the cards.
For a list of specific management information bases (MIBs) supported, see the
appropriate Hotwire DSLAM Network Configuration Guide.

The Hotwire 8610 DSLAM consists of the following components:
HHotwire 8610 DSLAM base chassis
Hotwire 8610 DSLAM is a 3-slot chassis designed to house one MCP card in the
first slot and up to two DSL cards in the remaining slots. Since the MCP card in the
8610 system can provide management connectivity for up to five other 8610
DSLAMs, these other systems can use the first slot for a DSL card, thus housing
up to three DSL cards.
HOne Management Control Processor (MCP) card
The Hotwire 8610 DSLAM requires one MCP card mounted in Slot 1 of the base,
or first, chassis in a stack. The MCP card is a processor card that administers and
provides diagnostic connectivity to DSL cards in from one to six 8610 DSLAMs. It
acts as a mid-level manager and works in conjunction with an SNMP network
management system, such as HP OpenView, via its LAN port. It gathers
operational status for each of the DSL cards and responds to the SNMP requests.
It also supports a serial port for local terminal access.
HAt least one Digital Subscriber Line (DSL) card
The 8610 DSLAM requires at least one DSL card. Each DSL card contains a
number of DSL ports (depending on model), Ethernet interface circuitry, and a
processor. The processor controls the modems and forwards the packet traffic to
and from the Ethernet and DSL interfaces.
NOTE:
You must order the MCP and DSL cards separately. They are not provided with the
chassis.

6
Preinstallation Considerations
Consider the following before performing installation of the 8610 chassis:
HInstallation Site
Your installation site should be well ventilated, clean, and free of environmental
extremes. If you are installing the Hotwire 8610 DSLAM chassis in a central office
rack, make sure there is 2 to 3 feet of clearance at the front of the rack in which the
8610 chassis is to be installed to allow access for the installation of the chassis,
circuit cards, and cables. Also allow for proper clearance at the rear of the chassis
for cabling, if using the rear cable connectors.
HPower
The ac power version requires a power source of 100–250 Vac @ 50–60 Hz;
maximum current draw is 3 amps @ 110 Vac.
The dc power version requires a –48 Vdc power source (–40.0 to –60.0 Vdc;
maximum current draw is 2 amps). The size of power source wires must be
between 14 AWG and 18 AWG, and can be either solid or stranded. However,
16 AWG stranded wire is recommended.
HGrounding
A ground lug is located at the lower right of the cover at the rear. It accepts
14 AWG wire.
A noninsulated banana jack is located at the left front side of the unit to provide a
ground for the ESD wrist strap plug.
HStacking
Up to three 8610 chassis may be physically stacked safely on top of each other.
However, for stacks of more than three, start a second stack or mount in a 19- or
23-inch rack. Contact your sales representative for ordering information.
HCabling
Use only CAT3 or better twisted-pair network connection cables for DSL
Termination Unit connections and interface patch cabling. Untwisted analog cables
of any length anywhere in the loop substantially contribute to crosstalk and
reduced loop reach.
The following customer-provided cables and cable adapters are required with this
product:
— Plug-ended Telco 50-pin cable for connection from the Hotwire 8610 DSLAM
Line ports to the CO POTS splitter shelf or MDF, one cable per DSL card.
— 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection to
the DSL 10BaseT Ethernet ports. You will need this cable for accessing the
LAN/WAN circuits of each DSL card.
— 8-pin UTP CAT5 modular cable for connection from the Hotwire 8610 DSLAM
MANAGEMENT MCP port to a 10BaseT hub connector (connected to an
SNMP management system network) for Slot 1 in the base chassis. For other
chassis in a stack, use this cable for daisy chaining the chassis together. For
M/HDSL and M/SDSL cards, refer to the appropriate card Installation
Instructions for the correct cable needed.

7
— 14-foot serial cable and DB25 and DB9 adapters are shipped with the MCP
card. For connection to a modem, you will need a NULL modem adapter.
If there is adequate maintenance space at the rear of the rack, mount the chassis
on the rack before installing cables. If there is inadequate space to do this, install
the rear-mounted network connectors on the chassis before mounting the chassis
on the rack.
CAUTION:
Use of any nontwisted pair wiring arrangements, such as jumpers, can cause
reduction in overall DSL reach performance, even over short distances.
NOTE:
Each Hotwire 8610 DSLAM chassis weighs approximately nine pounds (with circuit
cards) and can be easily installed by one installer.
Unpacking the Hardware
When shipped, the Hotwire 8610 DSLAM chassis is packed in a cardboard shipping
container. Carefully remove the 8610 chassis from its shipping container and check for
physical damage. If the 8610 chassis shows signs of shipping damage, report this
immediately to your shipping and sales representatives.
Package Contents
The Hotwire 8610 DSLAM chassis, as shipped, consists of the following:
HThree filler plates installed in Slots 1, 2, and 3.
Hac power cord (if your chassis has the ac power option)
HTwo reversible mounting brackets (for 19- and 23-inch rack mounting)
HAssociated hardware bundled in a plastic bag:
— Four #10-32 mounting screws
— Four #12-24 mounting screws and four #12-24 Speed Nuts (for use with racks
without threaded mounting holes)
— Four #8-32 Phillips pan-head screws for center mounting
— Three #4-40 Phillips pan-head screws (to replace longer Telco captive screws
when using the rear-mounted connectors)
NOTE:
The Hotwire 8610 DSLAM chassis requires an MCP card and at least one DSL
card for proper functionality. These cards are not
provided as part of the 8610
chassis and must be ordered separately.

Hotwire 8610 DSLAM Chassis Installation
The Hotwire 8610 DSLAM chassis is designed to be stacked one on top of the other on
a desktop or table, or mounted in a 19-or 23-inch rack (front or center mount). Up to
three 8610 chassis can be stacked on a table or desktop. Mounting brackets are
provided for mounting in 19- or 23-inch racks.
You will need a large, flat-blade screwdriver and a Phillips screwdriver to install the
8610 chassis in a commercial EIA-standard 19- or 23-inch rack. You will need a small
phillips screwdriver to change the STACK POSITION switch.
Stacking the 8610 Chassis
"Procedure
To stack the 8610 chassis on a desktop or table, select the stack position, and
interconnect the stack:
1. Place the first Hotwire 8610 DSLAM chassis on a desktop or table.
2. Place the second Hotwire 8610 DSLAM chassis directly on top of the first chassis.
3. Place the third Hotwire 8610 DSLAM chassis directly on top of the second chassis.
4. Change the setting of the rotary STACK POSITION switch to the appropriate
position of the chassis using a small Phillips screwdriver. Examine the switch
closely to be sure the switch is set so that the notch points to the position number.
— The base chassis
containing the MCP card
must be set to Stack
Position 1.
— The chassis directly on
top of the base chassis
must be set to Stack
Position 2.
— The chassis directly on
top of the second chassis
must be set to Stack
Position 3.
— Start a second stack for
chassis four through six
with the Stack Position
switch set appropriately.

10
Interconnecting 8610 Systems
"Procedure
To interconnect multiple 8610 systems:
1. Connect the end of an 8-pin modular cable into the Management OUT port of the
base chassis.
2. Dress the 8-pin modular cable to the left and under the chassis, behind the foot,
and up the side of the unit.
3. Plug the other end of the 8-pin modular cable into the Management IN port of the
8610 chassis above, dressing the cable as in the previous step.
4. Repeat for the next 8610 chassis, connecting the Management OUT port of
Chassis 2 to the Management IN port of Chassis 3.
NOTE:
Bus cables must use Unshielded Twisted Pair (UTP) CAT5 cable. The total bus
cabling should not exceed 25 feet.

11
The following illustration shows the designated number for each DSL card slot in a
stack.
NOTE:
This illustration shows a stack of six Hotwire 8610 systems, which is valid for rack
mounting. However, the same relationship of software-assigned slot numbers
applies to two stacks of three each, mounted on a desk or tabletop and connected
by a bus cable. The base chassis must still have the MCP card in physical Slot 1
with the base chassis Stack Position switch set to 1. The software does not assign
a slot number to the MCP card.

Supplying Power
The Hotwire 8610 DSLAM chassis is available in two versions:
Hdc power (–40.0 to –60.0 Vdc; maximum current draw is 2 amps)
— The dc version has two separate dc inputs, A and B, to provide power
redundancy.
Hac power (100–250V; 50–60 Hz; maximum current draw is 3 amps @ 110 Vac)
— The ac version can provide power redundancy if a separate –48 Vdc source is
connected to the B input terminal.
CAUTION:
It is recommended that the following procedures be performed by a qualified
electrician.
Using a Single DC Power Source
"Procedure
To supply –48 Vdc power to the 8610 chassis from a single –48 Vdc power source:
Make sure that the dc power source wires are not powered (i.e., the circuit
breakers are open).
The ends of the power source wires (14–18 AWG solid or stranded wire) must
be stripped of insulation. If the wires are not stripped, strip the tip of each wire
(about 1/2-inch in length) before inserting the wire into the appropriate terminal
on the –48V input terminal block. Ensure that each wire is fully inserted into
the terminal (until it can go no further).
1. Insert the following wires into Terminal A and securely fasten each wire by
tightening the screw above it. The insulation should be fully within the terminal
block and no bare wire should be exposed outside of the block.
NOTE:
You should clearly label these power source wires as –48V and RTN
respectively.
Insert Power Source A’s . . . Into the . . .
Negative side of the power source –48V A input terminal.
Positive side of the power source RTN A (return) terminal.

Installing the Cards
Use a small- to medium-size flat-blade screwdriver to install the MCP and DSL cards.
The MCP card
must be installed in Slot 1 of the base chassis.
CAUTION:
Do not insert the MCP card into Slots 2 or 3 as this will damage the DSLAM
chassis. The MCP card must be used in Slot 1 of the base 8610 chassis for
proper functionality. Only use the MCP card in an 8610 chassis. Do
not try to
use an MCC or MCC Plus card.
A circuit card may be replaced without disruption to user data (i.e., you can remove and
reinstall a card without powering down the 8610 chassis and disrupting user data on
the other cards). To remove the card from the chassis, unfasten the screws on both
ends of the faceplate. Then, simply push the ejector handles outward and slide the card
out.
