1. Introduction
1-2 April 2001 8610-A2-GN20-10
The 8610 DSLAM accepts the following types of IP Conservative cards:

MVL®, ReachDSL™/MVL, RADSL, IDSL, SDSL, and TDM SDSL 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 interfacesi. Models include:
—8310 4-port and 8312 12-port Multiple Virtual Lines (MVL) cards that
interoperate with the Hotwire 6310 modem.
—8312 12-port ReachDSL/MVL card that interoperates with the Hotwire
6310 MVL and 6350 ReachDSL modems.
—8510 4-port and 8373 12-port Rate Adaptive Digital Subscriber Line
(RADSL) cards that interoperate with the 5620 Remote Termination Unit
(RTU) or the 6371 RADSL Router.
—8303 Integrated Services Digital Network Digital Subscriber Line (IDSL)
2B1Q card that interoperates with the 6301 or 6302 IDSL Router.
—8343 Symmetric Digital Subscriber Line (SDSL) CAP card that
interoperates with the 6341 or 6342 SDSL Router.
The 8610 DSLAM accepts the following types of IP Complex cards:

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.
The 8610 DSLAM also accepts the TDM SDSL cards that are neither
IP Conservative nor IP Complex:

Management 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 OpenLane®, 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.
NOTES:
—IP Conservative and IP Complex cards cannot be installed in the same
chassis.
—RADSL, MVL, ReachDSL/MVL, IDSL, SDSL, and TDM SDSL cards are
generically referred to as DSL cards in this document.

1. Introduction
8610-A2-GN20-10 April 2001 1-3
Hotwire 8610 DSLAM Features
The Hotwire 8610 DSLAM chassis has the following features:


Power Redundancy


AC and DC Powered Models
Two versions of the Hotwire 8610 DSLAM chassis are available:
—AC power
The AC version will operate from 100 to 240 volts AC (nominal), 50 to
60 Hz. It can also be connected to a DC source to provide power
redundancy.
—DC power
The DC version requires a source of 48 VDC. 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.

Stackable Chassis for DSL Access Growth
Each chassis is an independent, standalone system. However, the chassis
can be combined in a stack for more efficient operation. 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.


Hot 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.

Primary 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 OpenLane). The MCP card gathers all management
information for each of the DSL cards and responds to the SNMP requests on
behalf of the cards.

Hotwire 8610 DSLAM Components
The Hotwire 8610 DSLAM consists of the following components:

Hotwire 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.

One 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 OpenLane, 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.

At 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.

Installation
Preinstallation Considerations
Consider the following before performing installation of the Hotwire 8610 DSLAM
chassis:

Installation 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.

Power
The AC power version requires a power source of 100–250 VAC @ 50–60 Hz;
maximum current draw is 2.5 amps @ 100 VAC.
The DC power version requires a –48 VDC power source (–40.0 to
–60.0 VDC; maximum current draw is 2.0 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.


Grounding
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.

Stacking
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.

Cabling
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 10/100 BaseT 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 10/100 BaseT 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.
—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:

Three filler plates installed in Slots 1, 2, and 3.

AC power cord (if your chassis has the AC power option)

Two reversible mounting brackets (for 19- and 23-inch rack mounting)

Associated 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.
Be sure to register your warranty at www.paradyne.com/warranty.

Mounting Configurations
The Hotwire 8610 DSLAM chassis can be mounted in any commercial Electronic
Industries Association (EIA) standard 19- or 23-inch rack. Both 19- and 23-inch
rack-mounting hardware is provided with the unit. In a typical mounting
configuration, up to 14 Hotwire 8610 DSLAM chassis can be mounted in a 7-foot
rack. This illustration shows the Hotwire 8610 DSLAM chassis installed in a rack.
In addition, the Hotwire 8610
DSLAM chassis can be placed on
a desk or table, and stacked on top
of each other. For stability, do not
set more than three Hotwire 8610
chassis on top of each other in a
single stack on a desk or tabletop.
Two physical stacks of three
chassis can be interconnected to
provide shared management
access for six Hotwire 8610
chassis.
If you are installing an 8610
chassis in a stack with existing
8600 chassis, make sure that the
8610 chassis is the master chassis.
NOTE:
In this guide, the term
rack
refers to a CO rack, cabinet, frame, or bay.
