Safety Warnings
• The intra-building port(s) of the equipment or subassembly is suitable for connection to
intrabuilding or unexposed wiring or cabling only. The intra-building port(s) of the
equipment or subassembly MUST NOT be metallically connected to interfaces that
connect to the OSP or its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and
require isolation from the exposed OSP cabling. The addition of Primary Protectors is not
sufficient protection in order to connect these interfaces metallically to OSP wiring.
The intra-building port(s) of the equipment is suitable for connection only to shielded
intra-building cabling grounded at both ends.
Your product is marked with this symbol, which is known as the WEEE mark. WEEE stands
for Waste Electronics and Electrical Equipment. It means that used electrical and electronic
products should not be mixed with general waste. Used electrical and electronic equipment
should be treated separately.

CHAPTER 1
Introducing the IP DSLAM
This chapter introduces the main applications and features of the IP DSLAM. It also
introduces the ways you can manage the IP DSLAM.
1.1 Overview
This chapter describes the system features, applications and specifications of your IP DSLAM.
The IP DSLAM is an IP-based DSLAM (Internet Protocol Digital Subscriber Line Access
Multiplexer) that connects VDSL and voice subscribers to the Internet. As a high-performance
but yet compact platform, it can conveniently deliver broadband Internet access and VoIP
telephony service (over existing POTS telephone wiring) to multi-tenant units (MTUs),
hospitals, hotels, schools, university campuses and ISPs. The IP DSLAM’s low cost and easy
management make it a perfect DSL-provider solution.
The IP DSLAM platform allows for convenient management and support of VDSL
technology. Up to 24 VDSL subscribers can simultaneously utilize a wide range of powerful
broadband services.
1.2 Applications
These are the main applications for the IP DSLAM:
• Internet access, multimedia and phone services for Multiple Tenant Units (MTU).
• Other applications include telemedicine, surveillance systems, remote server systems,
cellular base stations and high-quality teleconferencing.
1.2.1 MTU Application
The following diagram depicts a typical application of the IP DSLAM with ADSL modems, in
a large residential building, or multiple tenant unit (MTU), that leverages existing phone line
wiring to provide Internet access and voice service to all tenants. Note that ADSL service can
coexist with voice service on the same line.
VES-1624FT-55A User’s Guide
33
Chapter 1 Introducing the IP DSLAM
Figure 1 MTU Application
1.2.2 Curbside Application
The IP DSLAM can also be used by an Internet Service Provider (ISP) in a street cabinet to
form a “mini POP (Point-of-Presence)” to provide broadband and phone services to residential
areas that are too far away from the ISP to avail of DSL or PSTN phone service. Residents
need an ADSL modem for data services, connected as shown in the previous figure.

Chapter 1 Introducing the IP DSLAM
1.3 Hardware Features
This section describes the ports on the IP DSLAM.
1000/100 Mbps Ethernet Ports
The IP DSLAM has two 1000/100Mbps auto-sensing Ethernet ports.
They allow you to:
• Connect the IP DSLAM to a second-level IP DSLAM
• Daisy-chain other IP DSLAM
SFP Slots
Install SFP (Small Form-factor Pluggable) transceivers in these slots to connect to other IP
DSLAMs at longer distances than the Ethernet port.
Stacking
Daisy-chain up to three IP DSLAM (or other Ethernet devices).
Integrated Splitters
The integrated DSL splitter eliminates the need to use external splitters that separate the voiceband and VDSL signals.
Console Port
Use the console port for local management of the IP DSLAM.
VES-1624FT-55A User’s Guide
35
Chapter 1 Introducing the IP DSLAM
Fans
The fans cool the IP DSLAM sufficiently to allow reliable operation of the IP DSLAM in even
poorly ventilated rooms or basements. To conserve energy and reduce noise, the fan speed
depends on the temperature.
Alarm LED
An ALM (alarm) LED lights when the IP DSLAM is overheated, the fans are not working
properly , the voltage readings are outside the tolerance levels or an alarm has been detected on
the ALARM input pins.
Outband Management Interface
The IP DSLAM has one 10/100 auto-sensing UTP (unshielded twisted pair) port for outband
Ethernet Manament.
1.4 Software Features
This section describes the general software features of the IP DSLAM.
System Monitoring
• System status (link status, rates, statistics counters)
• Temperatures, voltage reports and alarms.
DMT Modulation
The IP DSLAM, with the VDSL modem such as P-870H-51 or P-870HW-51, offers service
providers a DMT (Discrete Multi-T one)-based VDSL solution. DMT modulation allows the IP
DSLAM to dynamically adapt to the bit rate based on the line condition.
Band Plan Support
Band plan is controlled by Limit PSD Mask (refer to Section 16.4.2 on page 100). All options
of Limit PSD Mask for this IP DSLAM follow the band plan defined in G.993.2.The IP
DSLAM supports VDSL band Plan.
VDSL Profiles
Profiles allow you to configure VDSL ports efficiently. You can configure all of the VDSL
ports with the same profile, thus removing the need to configure the VDSL ports one-by-one.
You can also change an individual VDSL port by assigning it a different profile. The [Product
Name (long)]
supports the VDSL2 profiles including
• The DS1 frequency band of the 17a profile starts at 138 kHz and the edge freq uency of the
upper band of the 17a profile is 17.664 MHz.
• The VDSL2 profiles are programmable and automatically adapt according to the line
condition of each VDSL2 line.

IP Protocols
• IP Host (No routing)
• Telnet for configuration and monitoring
• SNMP for management
• SNMP MIB II (RFC 1213)
• SNMP v1 RFC 1157
• SNMPv2, SNMPv2c or later version
• Bridge MIBs (RFC 1493, 2674)
• SMI RFC 1155
•Private MIBs
• RFC 3728 VDSL MIB
VDSL2 to ADSL2+ Fall Back
The IP DSLAM provides ADSL2+ fall back feature in addition to the VDSL2 PTM (Packet
Transmission Mode) service. W ith ADSL2+ fall back turned on, the IP DSLAM can de tect an
ADSL modem connected to a subscriber line. Then the IP DSLAM switches the operation
mode of the corresponding port to ADSL2+ and establishes the corresponding connection service. This helps Telco operators to provide differentiating services (ADSL service can coexist
with VDSL service on the same subscriber line) using a single DSLAM. At the time of writing, the IP DSLAM supports the following features.
• ADSL2+ fall back
• Bi-directional AAL5 ATM VCs
• PPPoA and IPoA/IPoE
• PVC to VLAN mapping
Refer to ITU-T G.992.1, G.992.3 and G. 992.5 for more information.
IEEE 802.1Q Tagged VLAN
Your management IP DSLAM card uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area
Network), which allows your device to deliver tagged/untagged frames to and from its ports.
IEEE 802.1p Priority
Your IP DSLAM uses IEEE 802.1p Priority to assign priority levels to individual PVCs.
IGMP Count Limit
You can limit the number of IGMP groups a subscriber on a port can join. You may enable/
disable the IGMP count limit on individual ports.
Static Multicast
Use static multicast to allow incoming frames based on multicast MAC address(es) that you
specify. This feature can be used in conjunction with IGMP snooping and IGMP proxy to
allow multicast MAC address(es) that are not learned by IGMP snooping or IGMP proxy.
VES-1624FT-55A User’s Guide
37
Chapter 1 Introducing the IP DSLAM
Multicast VLAN
Multicast VLAN is designed for applications (such as Media-on-Demand (MoD)) using
multicast traffic across an Ethernet ring-based service provider network. Multicast VLAN
allows one single multicast VLAN to be shared among different subscriber VLANs on the
network. This improves bandwidth utilization by reducing multicast traffic in the subscriber
VLANs and simplifies multicast group management.
VLAN Isolation
Use isolation to block the VDSL2 subscribers in a specific VLAN from sending traffic directly
to each other.
MAC (Media Access Control) Filter
Use the MAC filter to accept or deny incoming frames based on MAC (Media Access Control)
address(es) that you specify. You may enable/disable the MAC filter on specific ports. You
may specify up to ten MAC addresses per port.
Security
• Password protection for system management
•VLAN
• RADIUS client
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(R)STP detects and breaks network loops and provides backup links between IP DSLAMs,
bridges or routers. It allows a IP DSLAM to interact with other (R)STP -compliant IP
DSLAMs in your network to ensure that only one path exists between any two stations on the
network.
IEEE 802.1x Port-based Authentication
The IP DSLAM supports the IEEE 802.1x standard for centralized user authentication and
accounting management through an optional netw ork authentication (RADIUS) server.
MAC (Media Access Control) Count Filter
You can limit the number of MAC addresses that may be dynamically learned on a port. You
may enable/disable the MAC count filter on individual ports.
DHCP Relay
DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual
computers to obtain TCP/IP configuration at start-up from a server. You can configure the
system as a DHCP relay agent to have another DHCP server provide TCP/IP configuration for
the clients. In addition, you can set the system to forward client DHCP requests to specific
DHCP servers based on the VLAN ID. You can also specify up to two DHCP servers for each
VLAN to provide fail-over protection.
38
VES-1624FT-55A User’s Guide
Chapter 1 Introducing the IP DSLAM
DHCP Relay Option 82
The system supports DHCP relay agent82 (RFC 3046) that adds additional information to
client DHCP requests that the IP DSLAM relays to a DHCP server. It also supports adding the
sub-option 2 (Remote ID) with additional information.
DHCP Snooping
DHCP snooping allows the system to identify packets with DHCP server assigned IP
address(es) and block access of devices using unknown IP addresses on a subscriber port. You
can also manually add static IP addresses to the DHCP snooping table.
2684 Routed Mode
The IP DSLAM can handle 2684 routed mode traffic.
PPPoA-to-PPPoE (PAE) PVC
This feature allows the system to translate PPPoA packets to PPPoE packets (and vice versa)
to allow communication between CPE clients and an access concentrator (such as a BRAS)
through the IP DSLAM.
DSCP-to-IEEE 802.1p Priority Mapping
DiffServ is a class of service (CoS) model that marks packets with DiffServ Code Points
(DSCP) so that they receive specific per-hop treatment at DiffServ-compliant network devices
along the route. You can configure DSCP-to-IEEE 802.1p mappings to allow the IP DSLAM
to prioritize all incoming traffic based on the DSCP value according to the mapping table.
Transparent LAN Service (TLS)
Use TLS (also known as VLAN stacking) to add an outer VLAN tag to the inner IEEE 802.1Q
tagged frames that enter the network. By tagging the tagged frames (“double-tagged” frames),
the service provider can manage up to 4,094 VLAN groups with each group containing up to
4,094 customer VLANs. This allows a service provider to provide different services based on
specific VLANs, for many different customers.
Downstream Broadcast
The IP DSLAM can block downstream broadcast packets from being sent to specified VLANs
on specified ports.
Upstream Broadcast Rate Limiting
Rate Limiting on the subscriber ports allows service providers to offer tiered service in
increments of 32 Kbps. This service differentiation is not only to fulfill the needs of different
customers, but also to provide a network infrastructure that combines guaranteed performance
and flexibility in service provisioning.
System Error Logging
The IP DSLAM’s system error log will record error logs locally. These logs may be viewed
again after a warm restart.
VES-1624FT-55A User’s Guide
39
Chapter 1 Introducing the IP DSLAM
Management
• Remote configuration backup/restore and firmware upgrade
•SNMP manageable
• Text-based management locally via console port and remotely via telnet
• Editable plain text based configuration file
PPPoE Intermediate Agent Information
Similar to DHCP relay option82, you can set the system to insert line information into client
PPPoE Active Discovery Initialization (PADI) packets. This allows a PPPoE termination
server to identify and authenticate a PPPoE client.
Single End Loop Test (SELT)
This feature checks the distance to an ADSL subscriber’s location.
MAC Force Forwarding
This feature forces subscriber(s) to communicate with uplink device(s) through an IPv4
gateway. The gateway then routes or forwards subscriber traffic so the subscribers do not
know the MAC addresses of uplink devices on the network. A network administrator can
monitor monitor traffic on the gateway. You can also use this feature to distribute traffic
through different routers.

or the 1000 Mbps network link is down.
3.2 1000/100M Auto-Sensing Ethernet
The IP DSLAM has two 1000/100Mbps auto-sensing Ethernet ports. There are two factors
related to Ethernet: speed and duplex mode. In 1000/100Mbps Fast Ethernet, the speed can be
100Mbps or 1000Mbps and the duplex mode can be half duplex or full duplex. The autonegotiation capability makes one Ethernet port able to negotiate with a peer automatically to
obtain the connection speed and duplex mode that both ends support.
When auto-negotiation is turned on, an Ethernet port on the IP DSLAM negotiates with the
peer automatically to determine the connection speed and duplex mode. If the peer Ethernet
port does not support auto-negotiation or turns off this feature, the IP DSLAM determines the
connection speed by detecting the signal on the cable and using half duplex mode. When the
IP DSLAM’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed
and duplex mode when making a connection, thus requiring you to make sure that the settings
of the peer Ethernet port are the same in order to connect.
Use the Ethernet ports for subtending. Y ou can daisy chain mo re IP DSLAM or other Ethernet
switches.

Use with the following copper Ethernet cables: 1000Base-T 4-pair UTP Cat. 5e or Cat.6, up to
100m.
" For better performance and lower radiation noise, use shielded Ethernet
cables.
Each 1000/100M port is paired with a mini GBIC slot. The IP DSLAM uses up to one
connection for each pair for a total of two possible gigabit connections (one from each of the
two pairs). The IP DSLAM uses the mini GBIC transceiver whenever it has a connection.
3.2.1 Ethernet Default Settings
• Speed: Auto
• Duplex: Auto
3.3 SFP Mini GBIC Slots
The SFP slots can each house a mini GBIC (Gigabit Interface Converter) transceiver. A
transceiver is a single unit that houses a transmitter and a receiver. The IP DSLAM does not
come with a transceiver. You must use a transceiver that complies with the Small Form-factor
Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF8074i specification Rev 1.0 for details.
You can change transceivers while the IP DSLAM is operating. You can use different
transceivers to connect to Ethernet switches with different types of fiber-optic connectors.

Connect the mini-RJ-11 male end of the console cable to the console port of the IP DSLAM.
Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer.
3.5 ALARM Connection
A closed circuit on the ALARM input pins indicates an alarm. Pins 7 and 3 are alarm input
one. Pins 8 and 4 are alarm input two. Pins 8 and 5 are alarm input 3. Pins 9 and 8 are alarm
input 4.
The IP DSLAM signals an alarm when it detects an alarm on the ALARM input pins or the IP
DSLAM.
To signal an alarm, the IP DSLAM opens the circuit for pins 1 and 6 (the common pin) and
closes the circuit for pins 2 and 6.
Examples of an alarm on the IP DSLAM are when the IP DSLAM’s voltage or temperature is
outside of the normal range.

telephone company lines coming into a building and the telephone wiring in the building.
Figure 16 MDF (Main Distribution Frame) Wiring
• Connect wiring to end-user equipment to the lower ports of an MDF and connect wiring
from the telephone company to the upper ports of an MDF (see the previous figure).
• Some MDFs have surge protection circuitry built in between the two banks; thus, do not
connect telephone wires from the telephone company directly to your IP DSLAM.
VES-1624FT-55A User’s Guide
53
Chapter 4 MDF Connections
• Use a punch-down tool to seat telephone lines into MDF blocks.
• Multiple upper and lower MDF port connections are shown as one line in the following
figures.
4.3 Telco-50 Cables
Telco-50 cables are used for data and voice applications with MDFs (Main Distribution
Frame), patch panels and distribution boxes. They can also be used as extension cables. Telco50 cables are made up of 25 twisted-pair copper wires.
Connect a Telco-50 connector to one end of the cable (see Chapter 54 on page 283 for pin

This chapter tells how to access and navigate the web configurator.
7.1 Web Configurator Overview
The web configurator allows you to use a web browser to manage the IP DSLAM.
7.2 Screen Privilege Levels
There is a high or low privilege level for each screen.
High privilege screens are only available to administrators with high privilege access. High
privilege screens include things like creating administrator accounts, restarting the system,
saving changes to the nonvolatile memory and resetting to factory defaults. Nonvolatile
memory refers to the IP DSLAM’s storage that remains even if the IP DSLAM’s power is
turned off. Administrators with high privilege access can use all screens including the lower
privilege screens.
Administrators with the low privilege level are restricted to using only low privilege screens.
Low privilege screens are read only.
7.3 Accessing the Web Configurator
Use Internet Explorer 6 and later versions with JavaScript enabled.
Use the following instructions to log on to the web configurator.
1 Launch your web browser, and enter the IP address of the IP DSLAM (default:
192.168.0.1 for MGMT port or 192.168.1.1 for in-band ports) in the Location or

Switch Setup
The Switch Setup screen allows you to set up and configure global device features.
13.1 Switch Modes
The IP DSLAM supports daisychain and aggregation switch modes.
13.1.1 Daisychain Switch Mode
Daisychain switch mode sets the IP DSLAM to use Ethernet port one (ENET 1) as an uplink
port to connect to the Ethernet backbone and Ethernet port two (ENET 2) to connect to another
(daisychained or subtending) IP DSLAM. When you daisychain multiple IP DSLAM they
must all be set to daisychain mode.
Daisychain switch mode with port isolation enabled blocks communications between
subscriber ports on an individual IP DSLAM and between the subscribers of any daisychained
IP DSLAM (see Figure 40 on page 92 for an example). Use the same port isolation setting on
all IP DSLAM that you set up in a daisychain.
13.1.2 Port Isolation with Daisychain Switch Mode Example
In the example below, the IP DSLAM 1 has its Ethernet port one (ENET 1) connected to the
Ethernet backbone switch (3) and it’s Ethernet port two (ENET2) connected to Ethernet port
one (ENET 1) of the daisychained IP DSLAM (2).
With port isolation turned on, communications between A and B must first go through another
switch or router (3 in the figure). A and B also cannot communicate with C without their
communications going through another switch or router.

Select Auto (auto-negotiation) to have the IP DSLAM automatically determine
the type of connection that the Ethernet port has. When the peer Ethernet

auto-negotiation turned on, the IP DSLAM determines the connection speed by
detecting the signal on the cable and using full duplex.
When an Ethernet port is set to Auto, the IP DSLAM tries to make a fiber

CHAPTER 16
xDSL Port Setup
This chapter explains how to configure settings for profiles and individual DSL ports. It also
covers how to configure virtual channels and virtual channel profiles.
16.1 DSL Profiles
A DSL profile is a table that contains a list of pre-configured DSL settings. Each DSL port has
one (and only one) profile assigned to it at any given time. You can configure multiple
profiles, including profiles for troubleshooting. Profiles allow you to configure DSL ports
efficiently. You can configure many DSL ports with the same profile, thus removing the need
to configure the settings of each DSL port one-by-one. You can also change an individual DSL
port’s settings by assigning it a different profile.
For example, you could set up different profiles for different kinds of accounts (for example,
economy, standard and premium). Assign the appropriate profile to a DSL port and it takes
care of a large part of the port’s configuration. You still get to individually enable or disable
each port, as well as configure its channels and operational mode. See the chapter on profiles
for how to configure DSL profiles.
16.2 Alarm Profiles
Alarm profiles define DSL port alarm thresholds. The system sends an alarm trap and
generates a syslog entry when the thresholds of the alarm profile are exceeded. See the chapter
on profiles for how to configure alarm profiles.
16.3 Interleave Delay
Interleave delay is the wait (in milliseconds) that determines the size of a single block of data
to be interleaved (assembled) and then transmitted. Interleave delay is used when transmission
error correction (Reed-Solomon) is necessary due to a less than ideal telephone line. The
bigger the delay, the bigger the data block size, allowing better error correction to be
performed.
Reed-Solomon codes are block-based error correcting codes with a wide range of applications.
The Reed-Solomon encoder takes a block of digital data and adds extra "redundant" bits. The
Reed-Solomon decoder processes each block and attempts to correct errors and recover the
original data.
VES-1624FT-55A User’s Guide
99
Chapter 16 xDSL Port Setup
16.3.1 Fast Mode
Fast mode means no interleaving takes place and transmission is faster (a “fast channel”). This
would be suitable if you have a good line where little error correction is necessary.
16.4 VDSL Parameters
The following sections describe the VDSL parameters you configure in the following screens:
• xDSL Port Setup (see Section 16.9 on page 105).
• xDSL Port Profile (see Section 17.1 on page 117).
16.4.1 PSD
PSD (Power Spectral Density) defines the distribution of a VDSL line’s power in the
frequency domain. A PSD mask specifies the maximum allowable PSD for a line.
16.4.2 Limit PSD Mask
To reduce the impact of interference and attenuation, ITU-T 993.2 specifies a limit PSD mask
that limits the VDSL2 transmitters PSD at both downstream and upstream.
16.4.3 RFI (Radio Frequency Interference)
RFI is induced noise on the lines by surrounding radio frequency electrom agnetic radiation
from sources such as AM and HAM radio stations. Since VDSL uses a much larger frequency
range that overlaps with other radio frequency systems, signals from VDSL lines and other
radio systems interfere with each other. To avoid performance degradation due to RFI, set the
switch to not transmit VDSL signals in the RFI band defined by the regulatory bodies (ETSI
and ANSI). You can also configure your own RFI bands on the system.
16.4.4 Frequency Band Plan
Each VDSL mode operates in a different frequency band allocation, resulting in different
upstream and downstream speeds. Your Device automatically changes the band plan based on
the loop condition and loop length.
A band plan example is shown next. Band plans include an optional band (between 25 kHz
and 276 kHz) controlled by "limit PSD mask".
The optional band is used for upstream transmission which is to be negotiated during line
initiation. The optional band frequency (for example, the positions of x and y in the following
figure) varies depending on the limit PSD mask you use.
