1 Overview

The importance of IP has been validated by the year-to-year increase of new Internet

applications. New advances in IP networking technology 7324 RU have been introduced to

change the landscape of broadband service offerings.

Traditional ATM based DSLAM technology aggregates the ADSL traffic as ATM cell format, and

use ATM fabric switching technology to switch the ATM cell to the ATM network, normally the

switching capacity is about 155M to 622M, and through the traffic management to control the

congestion problems, it can provide the good QoS for both internet access and leased line

application. The conversion of traffic format is as the following diagram:

Figure 1-1 ATM Transmission

The new generation of DSLAM technology is IP-based DSLAM, it reduced the conversion of data

format, by using high switching and non-blocking of Ethernet technology to solve the traffic

congestion problem, it also provide a good mechanism for video multicasting application, such

as IGMP snooping. Teleco operator new deployment of networks can have another alternative

to deploy low cost of Ethernet metro and core network. The transmission of IP network is as the

following diagram:

Figure 1-2 IP Transmission

Alcatel’s 7324 RU is the IP-based DSLAM, which terminates all of the ATM circuits, and

converts the traffic directly into the Ethernet environment. The common design of 7324 RU

enhances the flexibility in new service offering and reduces the complexity of provisioning.

The IP core technology of 7324 RU enables service providers to deploy broadband service to

more customers quickly, and efficiently. Also it is flexibe in backhaul bandwidth upgrade and

reduces a lot of switch costs than previously possible.

2 7324 RU R3.0 Product Description

2.1 Product Overview

Ethernet service provisioning chassis switches are ideally suited for delivering broadband IP

services from service provider data centers, central office or multi-tenant buildings to

enterprise and home users. By utilizing xDSL technology, it provides services like Internet and

Multimedia to comprise high-quality vedio application.

The 7324 RU R3.0 platform provides total Ethernet coverage with support for both standard

Category 5 and fiber optic media as well as first mile technology 7324 RU R3.0 that extend the

reach of xDSL.

With a variety of DSL services, 7324 RU R3.0 is deigned for deployment in central office or data

center environment, where the services are directly delivered to customers through copper

wires, while the service reach can be extended up to 7,000 meters (23,000 feet) in case of

SHDSL connectivity., which covers around 80% of customer serving area. For the fiber to the

building (FTTB, FTTH, FTTC) architecture, 7324 RU R3.0 can be located in building telecom

room to deliver high bandwidth services to end-users. It is another market segment of revenue

generation tool for building owners and service providers.

The 7324 RU R3.0 is a chassis-based DSLAM which consists of 5 line cards and 1 management

and switching card, see Figure 2-1. All modules are hot-swappable design, which provideplug-and-play on-site operation.

Figure 2-1 7324 RU R3.0 120 ports xDSL DSLAM outlook

To extend the number of subscribers, subtending feature allows 7324 RU R3.0 to scale up by

connecting subtending interfaces to other systems via Gigabit Ethernet fiber or copper, the

3 7324 RU R3.0 Technical Description

3.1 Overview

The 7324 RU R3.0 is an IP core DSLAM design, which terminates all the ATM cells on xDSL

loops, and using a non-blocking Ethernet switching up to 12.8Gbps. The port trunking of

uplinks can aggregate the uplink traffic to easily upgrade the bandwidth to the backhaul. In

order to apply Ethernet technology for Teleco operators, 4096 VLAN ID are designed for

identifying xDSL subscribers and its service type, 802.1p priority queues are provided to

prioritize different type of service, for such of triple play services, subtending design protect

the Telecos’ investment on the equipment cost.

The system design is based on the following specification.

MSC1000 acts as a SNMP agent and provide the OAM&P function, through the different type of

management interfaces:

?? Mini RJ-11 local console port for CLI.

?? Telenet through in-band or out-band Ethernet port

MSC1000 provides three slots on its front panel for uplink and subtending purposes where

users can slide in different Ethernet modules. Those modules are not hot-swappable which

means the entire MSC1000 must be powered down when installing/uninstalling those

modules.

Four modules are available for Uplink and Subtending slots

consumption is about 300W, 8A. This module feeds the –48VDC to the back plane and contains

inductor to isolation electromagnetic interference, fuse and circuit breaker for over current

protection and MOV for surge (over voltage) protection. Each card in the 7324 RU R3.0 chassis

uses –48VDC input, and then convert the –48VDC to the required power on the boards. Owing

to the distributed power design, 7324 RU R3.0 can provide a reliable hot-swappable

mechanism.

The Main Characteristics are:

?? One 300V/12A 2.54mm terminal block with dual inputs

?? Dual 10A slow blow 5x20 mm fuses

?? Built in surge protection

?? Built in EMI filter

?? Rated Voltage -48.0 VDC

?? Operating Voltage: -36 ~ -57 VDC

?? Maximum power consumption: 300W

The other optional module feeds the –60VDC to the back plane and contains inductor to

isolation electromagnetic interference, fuse and circuit breaker for over current protection and

MOV for surge (over voltage) protection. Each card uses –60VDC input, and then convert the

–60VDC to the required power on the boards.

Figure 4-1 Front panel connection between main and splitter chassises

Splitters are typically used in a DSL system and to separate the voice and data signals from the

DSL lines, as the diagram shown below. In 7324 RU R3.0 all those interfaces go through

telco-50 connectors on front panel (to DSLAM) and on the splitter chassis rear panel (to PSTN

switch and to xdsl CPE).

Figure 4-2 Rear panel connection on splitter chassis

While installing 7324 RU R3.0, the telco-50 cables attaching to the USER connectors on splitter

chassis rear panel shall go to the CPE side, while telco-50 cables attaching to the CO

connectors shall go to the PSTN switch side, as shown below.
