What is the HotWire 8800 DSLAM?

The HotWire 8800 Digital Subscriber Line Access Multiplexer (DSLAM), which

can be installed in the Central Office (CO) or at an Internet Service Provider (ISP)

location adjacent to the CO, provides high-speed Internet or Intranet access.

Through the use of Digital Subscriber Line (DSL) technology, the DSLAM

provides simultaneous high-speed data access (digital) and POTS service

(analog) over the same twisted-pair telephone line. Support of this simultaneous

access requires the installation of POTS splitters at both ends of the line (i.e., at

the CO and at the customer premises (CP)).

When used in combination with a HotWire 8200 Interworking Packet

Concentrator (IPC), the HotWire 8800 DSLAM provides high-speed IP service

concentration over a wide array of LAN architectures as well as ATM interfaces to

Wide Area Networks.

HotWire 8800 DSLAM Components

The HotWire 8800 DSLAM system consists of the following components:

 HotWire 8800 DSLAM chassis

HotWire 8800 is a 20-slot chassis with integral power, alarm, cooling, and

interface subsystems designed to house up to 18 DSL cards and one

Management Communications Controller (MCC) card. (The remaining slot is

reserved for future use.)

 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 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.

 At least one Digital Subscriber Line (DSL) card

The chassis requires at least one DSL card, which is a circuit card that

contains four DSL ports, an Ethernet interface to the NSP, and a processor.

The processor controls the modems and forwards the packet traffic to and

from the Ethernet and DSL interfaces. When the chassis is fully populated, it

provides a total of 72 DSL ports.

NOTE:

You must order the MCC and DSL cards separately. They are not provided

with the chassis.

HotWire 8800 DSLAM Features

The HotWire 8800 DSLAM system has the following features:

 Power Redundancy and Load Sharing

The chassis provides a power input terminal block, which is capable of

accepting two independent –48 Vdc power inputs. Two power sources can

be connected to the chassis to provide power redundancy and load sharing.

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 chassis distributes –48 Vdc power from the CO power source to

individual cards via the interface module and the backplane.

 A Convenient Front-Facing Interface Panel

The interface panel on the chassis allows all interface cables to be connected

and maintained in the front of the chassis for easy accessibility.

 Major/Minor Alarm Contacts for CO Alarm Requirements

The interface panel provides two sets of dry contacts on a 6-pin jack interface

for connection to a Central Office (CO) alarm system.

 LED Monitors for Power and Fan Status and Major and Minor Alarms

LEDs on the front panel of the HotWire 8800 chassis are indicators of the

status of chassis functioning. For more information on the meaning of LED

indications, see Appendix A,

LEDs

.

 Hot Swappable Cards

The MCC and DSL cards can be installed and removed from the chassis

without service disruption to other cards.

Network Equipment Building Standards (NEBS)

The 8800 DSLAM meets Network Equipment Building Standards (NEBS) Level 2

Criteria. In addition, it meets NEBS Level 3 Earthquake (Zone 4 Level).

Refer to NEBS Heat Release Limits to determine the number of chassis that can

be mounted in a rack. Up to three HotWire 8800 DSLAMs may be mounted in a

7-foot rack and comply with NEBS Floor Heating Load Limits.

Unpacking the Hardware

When shipped, the HotWire 8800 DSLAM chassis is packed in a cardboard

shipping container. Carefully remove the chassis from its shipping container and

check for physical damage. If the chassis shows signs of shipping damage, report

this immediately to your shipping and sales representatives.

Pre-installation Considerations

Consider the following before performing the chassis installation:

 Installation Site

Your installation site should be well-ventilated, clean, and free of

environmental extremes. There should be 2 to 3 feet of clearance at the front

of the rack in which the chassis is to be installed to allow access for the

installation of the chassis, circuit cards, and cables.

 Power

The HotWire 8800 DSLAM operates from a standard CO –48 Vdc power

supply (–40.0 to –60.0 Vdc). The power source wires must be between

10 AWG and 16 AWG, and can be either solid or stranded. However, the

preferred power source wire type is 14 AWG stranded.

 Grounding

A copper lug connector is attached to the chassis grounding post. It can

accept a bare wire, 6 through 14 AWG.

 Cabling

The following customer-provided cables and cable adapters are required with

this product:

— Telco 50-pin cable for connection to the CO POTS splitter shelf or MDF.

You will need one 50-pin cable for Slots 1 – 6, one 50-pin cable for

Slots 7 – 12, and one 50-pin cable for Slots 13 – 18.

— 6-pin modular cable for connection to a CO alarm system, if required.

— 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection

to the DSL 10BaseT Ethernet ports. You will need a cable for each card

in the DSLAM.

— 8-pin UTP CAT5 modular cable for connection to management domain

LAN for SNMP management system or telnet access.

— A CAT5 serial cable and DB25 (male) adapter are shipped with the MCC

card. However, for connection to a terminal or computer, you may have to

supply a (female) DB9 to (male) DB25 adapter if your terminal or

computer has a 9-pin serial port. For connection to a modem, you may

need to supply a null modem adapter.
