Introduction

The Hotwire 8620 GranDSLAM

The Hotwire® 8620 GranDSLAM™, which is designed to be installed in an Internet Service Provider (ISP) or Network Access Provider (NAP) location, is a low-startup-cost alternative chassis to the Hotwire 8820 GranDSLAM chassis. The 8620 GranDSLAM can also be placed in a Remote Terminal (RT) adjacent to the Telco’s Digital Loop Carrier (DLC) systems. It provides high-speed Internet or intranet access.

The System Interface Module (SIM) is shipped with the chassis already installed in the bottom slot. The SIM provides user interface connections on the front of the GranDSLAM.

An Asynchronous Transfer Mode (ATM) backplane provides ATM aggregation across multiple DSL port cards.

With Release 3.0 of the GranDSLAM, there are two configurations:

n SCM-based. A Management Control Processor (MCP) card is installed in

Slot 1 for management of the DSL cards. A Shelf Concentration Module (SCM), installed in Slot A, provides aggregation of DSL traffic for the chassis. The chassis supports up to two DSL cards and 48 ports.

n SCP-card-based. A Shelf Concentration and Processing (SCP) card is

installed in Slot A to provide the management functions of the MCP and the aggregation functions of the SCM. The chassis supports up to three DSL cards and 72 ports.

The SCP card supports Models 8955, 8965, and 8985 ATM line cards. With an MCP installed, legacy TDM cards (Models 8775, 8777, 8779, and 8799) are also supported.

The following illustration shows a high-level view of a typical Hotwire configuration.

Hotwire 8620 GranDSLAM F ea tures

The Hotwire 8620 GranDSLAM chassis has the following features:

n AC and DC Powered Models

Two versions of the Hotwire 8620 GranDSLAM chassis are available: — AC powered. 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.

8303 8304 8312 8314 8335 8343 8344 8355 8365 8373 8374 8385 8777 8779 8799

— DC powered. 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.

n Hot Swappable Cards

The MCP and DSL cards can be installed and removed from the Hotwire 8620 GranDSLAM chassis without service disruption. You can replace these cards without powering down the chassis and disrupting service to the other cards. Removing the SCM card disrupts traffic on DSL port cards.

n Primary Network Management Support via SNMP

SNMP management of the DSL cards is accomplished over a single external Ethernet or inband management 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.

For a list of specific management information bases (MIBs) supported, visit the Paradyne website www.paradyne.com. Select Support
