Observing Safety Precautions

OBSERVING SAFETY PRECAUTIONS
Follow the appropriate warnings and cautions when performing the tasks specified in this
manual. You must connect the specified cables and wires only in the order listed and as
indicated in the installation instructions. Additionally, read and understand all installation
procedures before beginning.
•

Follow local grounding practice to ensure a good frame ground connection
to the AV8000 chassis. The frame ground is required for secondary voltage
protection.

•

Electrical and mechanical shock hazards are present throughout the
system; be aware of this possibility when power is applied to the chassis.
Only qualified personnel should service the system.

•

Do not connect the AV8000 chassis battery wires to a live power source.
Ensure that you remove fuses from the CO equipment bay for each circuit
you will use.

•

The equipment must be connected to a protective ground in accordance
with the instructions provided in this manual. Improper grounding may
result in an electrical shock.

•

The minimum bend radius for a fiber-optic cable is 1.5 inches (38.10 mm).
Do not use a bend radius of less than 1.5 inches when looping the
fiber-optic cable in the cable tray.

•

Do not look directly at the fiber-optic ports on the front of the OC3 network
card or into the end of any fiber-optic cable.

OBSERVING ESD PRECAUTIONS
Observe these electrostatic discharge (ESD) precautions when installing the AV8000 system.
Follow installation procedures in the order that they are given.

This symbol placed next to a paragraph title or within a paragraph indicates
that the entire procedure involves equipment sensitive to electrostatic
discharge. You must wear an antistatic wrist strap connected to the ESD jack
on the AV8000 chassis to perform the installation procedures. You must also
observe normal ESD precautions when handling electronic equipment. Do not
hold electronic plugs by their edge. Do not touch components or circuitry.

AV8000 Installation Manual

Chapter 1: Prepare for Installation

PLANNING THE AVIDIA SYSTEM
Use the following sections to select components for the Avidia system. Allow for future
expansion when you select and place components.

Compatibility
Select components for your system that are compatible:
•

network card(s) to meet the network interface requirement, as well as the bandwidth and
traffic needs of your network (see “Adding to an Existing System” on page 5 for other uses
of network cards)
If selecting an ADSL subscriber card, use the Avidia Model AV541-LP (with line
protection) to connect directly to an MDF. Use the Avidia Model AV541 to
connect to a voice shelf.

•

subscriber cards to meet the network, transmission, and distance needs for your subscribers,
for example:
–

Does symmetric (frame SDSL, IDSL) or asymmetric (ADSL) transmission best meet
the applications needs for the subscriber?

–

Which transmission type provides service to a subscriber who is distant from the CO?

–

Which transmission type provides the appropriate rate for the reach?

•

for POTS, use ADSL subscriber cards AV541 (without line protection) and connect to a
VOICE shelf to multiplex voice and data

•

Customer Premises Equipment (CPE) must be compatible with transmission type of the
subscriber card, for example:
–

for ADSL subscriber cards, use Megabit Modem 700F, 600F, 500L, 400F or other
DMT ADSL modems

–

for frame SDSL subscriber cards, use Megabit Modem 300S or other SDSL modems

–

for IDSL subscriber cards, use modems recommended as a result of compatibility
testing and listed on the ADC.com Web site

–

for cell SDSL subscriber cards, use modems recommended as a result of compatibility
testing and listed on the ADC.com Web site

AV8000 Installation Manual

Planning the Avidia System

Card Placement
You may want to strategically leave slots available for expansion (see “Adding to an Existing
System” on page 5). Install cards in these AV8000 chassis slots:

•

management card in slot 1

•

OC3, DS3, and DSX-1 network cards in slots 11 and 12 (OC3 card can be used in a
subscriber slot for special applications such as subtending, see Chapter 8); typically, use
slot 12 as the primary network card slot

•

8xDS1and 8xE1 network card in any subscriber card slot (S2 through S10 and
S13 through S21)

•

ADSL, cell SDSL, frame SDSL, and IDSL subscriber cards in any subscriber card slot
S2 through S10 and S13 through S21, in any combination (it is efficient to place ADSL
cards in adjacent slots for cabling purposes when you connect to a Voice shelf to combine
voice and data)

•

Empty card slots should be filled with one or more of the blank faceplates provided with
the AV8000. This not only reduces the levels of electromagnetic radiation emanating from
the chassis, but also aids in maintaining optimum cooling for the cards installed in the
system.

AV8000 Installation Manual

Chapter 1: Prepare for Installation

Adding to an Existing System
When selecting system components, consider future expansion to your Avidia system, with
these as possible options:

If you want to add a:

Then:

AV8000 Chassis

Consider installing the first chassis in the top position in a 7-foot
Telco rack to allow further expansion in the middle and bottom
positions. Remember, you can have a maximum of three AV8000
chassis per rack, when a fuse panel is not installed in the same rack.

Network card for:
Redundancy

Add a second network card, of the same type, in slot 11 to have a
backup connection to the same network uplink source.

Second network connection

Add a second network card, of the same or of a different type, in slot
11 to connect to a separate or second network uplink source.

Subtending

Add a one or more additional network cards to subtend other Avidia
chassis that are downstream from the subtending chassis. This card
can be:
• another DS3 card in slot 11
• another OC3 card in slot 11 or any subscriber slot (2-10 or 13-21)
• 8xDS1 card in any subscriber slot (2-10 or 13-21)
• 8xE1 card in any subscriber slot (2-10 or 13-21)

Subscriber card

Leave subscriber slots (2-10 or 13-21) open to accommodate
expansion of subscriber services. You may want to group cards in
the chassis for ease of cabling. There is no technology limitation,
however, for card placement. Available xDSL cards are:
• 12-port ADSL (two 12-port ADSL cards are available (AV541 and
AV541-LP). Use the AV541-LP card when connecting the ADSL
subscriber line directly to the MDF for data transmission that
does not include POTS. Use the AV541-LP card when you
connect the subscriber line to a voice shelf to multiplex data with
POTS. The voice shelf provides the line protection required for the
ADSL card.
• 24-port cell SDSL
• 24-port frame SDSL
• 24-port IDSL

POTS with ADSL

AV8000 Installation Manual

Leave space in the CO rack for co-locating a voice shelf. Also, when
you combine a voice shelf with an AV8000 chassis for implementing
data and POTS, select the ADSL card without line protection. The
voice shelf provides line protection for the ADSL card.

Installation Site Requirements

INSTALLATION SITE REQUIREMENTS
Chassis Installation Requirements
The AV8000 mounts in a 23-inch, 7-foot or 71/2-foot CO Telco rack. You can install up to three
chassis in one rack. Allow adequate space for ventilation and cabling. The table below shows
chassis dimensions and minimum clearances for installation.
Weight

67 lbs (30.39 kg) for chassis without cards

Height

24.47 inches (621.54 mm)
(requires 14U space—1U = 1.75" of usable internal
rack space)

Depth

12.00 inches (304.80 mm)

Width

23.17 inches (588.52 mm) with mounting brackets
21.17 inches (537.72 mm) without mounting brackets

Clearance
between chassis

0.50 inches (12.70 mm) minimum
(this clearance applies to the bottom of the chassis only
and is required for fan air flow)

Power Requirements
Verify that the power source where you will connect the Avidia system is properly grounded
and falls within the recommended voltage range of -42.5 Vdc to -56.5 Vdc, with a minimum of
30 Amps.
Each AV8000 system provides a terminal block with connection points for two -48 Vdc Telco
supplied battery sources. Only one battery connection is required, with the second connection
provided for redundancy. The system also requires an external fuse panel with separate fusing
for each battery source used.

Alarm Requirements
The AV8000 system monitors alarm conditions, including alarms occurring at the remote end.
Connect alarm pins, when required by local practice, to indicate the alarm conditions such as
audible alarms, visual alarms, or power relay alarms. You can connect an Alarm Cut Off (ACO)
pushbutton to disable audible alarm output remotely.

AV8000 Installation Manual

Chapter 1: Prepare for Installation

Clocking Requirements
Avidia system clocking provides the capability to synchronize all data transmissions with a
common timing source within the Avidia System. Redundancy is provided, through the priority
ranking of clock sources, in order to achieve fault tolerance and timing recovery in the case of
a clock source failure. User configuration provides for selection and ranking of clock sources.
A clock source is selected for individual cards in a system. At this time, only the following
subscriber cards support the system clock (Sysref Clock) feature:
•

AMC

•

DS3

•

OC3

•

DSI/E1

•

IDSL

Clocking Systems
There are four related clocking systems associated with an Avidia chassis. These are discussed
in the following sections.

BITS OUT Clock
The first clocking system for the Avidia chassis is the BITS clock. A clock source is selected
that will serve as the BITS OUT clock. Potential BITS OUT clock sources are BITS IN 1, BITS
IN 2, or none. The BITS OUT clock source is selected by the user, through configuration
software, and routed by the primary network card to the BITS OUT wire wrap pins on the back
of the Avidia chassis.

Network Card Clock/System Reference Clock
The second clocking system is the System Reference clock (Sysref). Cards in the network card
slots, slots 11 and 12, are user configured to select the Sysref clock source. Both network card
slots can drive Sysref clock, but not at the same time. Normally, one network card (primary)
provides Sysref to the Avidia backplane and the other network card (secondary) uses the Sysref
clock off the backplane. The Sysref clock signal is also made available to all of the subscriber
cards from the backplane as well. Sysref clock sources are BITS IN 1, BITS IN 2, a network
card’s ports’ recovered receive clock, or the network card’s local oscillator. Sysref clock is
monitored by the network card for failure.

AV8000 Installation Manual

Installation Site Requirements

Subscriber Card Clock
The third clocking system provides clocking for the subscriber card. Subscriber card clock
sources are Sysref, subscriber card’s ports’ recovered receive clock, or subscriber card local
oscillator.

Port Clock
The fourth clocking system provides clocking for the subscriber card port. This clock is protocol
dependent. Potential port clock sources are:
•

Local (uses the card clock source that was selected for the subscriber card)

•

Loop (clock received at the port is recovered and used to transmit data).

If you do not configure a clock source for a card, configuration defaults to the card’s local
oscillator.

Typical Clock Source Configuration
Typically, the primary network card receives the master clock from a BITS clock such as a
Stratum 1 clock, through the chassis backplane inputs BITS IN 1 or BITS IN 2. The primary
network card outputs the clock signal BITS OUT, to the backplane wire wrap pins, and Sysref
to the Sysref backplane bus. The BITS OUT clock daisy chains the master clock (BITS out to
BITS in) through network cards from one Avidia shelf to the next in a central office rack. The
Sysref clock is distributed on the Backplane of the Avidia shelf for use by the subscriber cards
and the secondary network card not currently configured to supply this clock signal.
On the subscriber cards, the Sysref clock can be used to synchronize data transmissions. Or, the
user can configure the subscriber card to utilize the recovered received clock from a port for
transmitting data.

Clock Priority and Redundancy
Clock sources for the network cards and the subscriber cards are configured and ranked by the
user. Ranking allows you to indicate the priorities for each clocking source, through
configuration software, so that if the present clocking source should fail, the next lower ranked
clock source would take its place providing redundancy for the failed clocking source.
Clock sources are constantly monitored by Avidia software; therefore, when a failed clock
becomes available once again, the system automatically switches to this recovered higher
ranking clock source.

AV8000 Installation Manual

Chapter 1: Prepare for Installation

OC3
An OC3 network card has dual-PHY (two physical) connectors on the card front, behind the
safety cover. One interface provides the primary network uplink connection. The second
interface provides Automatic Protection Switching (APS), which is a redundant connection.
When implementing APS, provide cables and connectors for two physical ports. If not
implementing APS, provide a cable and connector for only one physical port. Select the fiber
and connector as follows, from the table below:
•

For an AV311 OC3 network card, use multimode fiber with SC fiber connectors.

•

For an AV312 OC3 intermediate-range (IR) network card, use single mode fiber with
SC fiber connectors.

•

For an AV313 OC3 long-range (LR) network card, use single mode fiber with SC fiber
connectors.
The minimum bend radius for the fiber-optic cable is 1.5 inches (38.10 mm).
The diameter of the core/cladding is 62.5/125.5 µm (micrometers).

Chapter 3: Install the Network Interface

DS3 INTERFACE CABLES
The DS3 network card provides an interface between the AV8000 system and an ATM
backbone network. The interface to a DS3 network card in slot 11 or 12 is made to a pair of
BNC connectors on the AV8000 backplane (page 32). Use the BNC connector pair as follows:
•

DS3-1 for the network card in slot 12

•

DS3-2 for the network card in slot 11
Either DS3 network card can be configured to connect to either set of DS3 BNC
connectors on the AV8000 back plane. During initialization however, the
software assigns the DS3-1 connector to slot 12 and the DS3-2 connector to
slot 11.

For each BNC connector pair, the connectors are labeled:
•

TX BNC for the transmit signal from the Avidia network card to the network

•

RX BNC for the receive signal from the network to the Avidia network card
Recommendation: Use a 75 Ω coaxial cable with 75 Ω BNC connectors and
a maximum length of 450 feet (137.16 m). Ground the cable shield at one end
only.

When you use two DS3 cards in an AV8000 system, connect the cables (steps on page 35) for
one of the following modes (shown in the figure below):
•

single physical link mode (one network connection)

•

dual physical link mode (two network connections)

•

subtending (one network upstream connection, one network downstream connection)

OC3 Fiber-Optic Cable Routing

OC3 FIBER-OPTIC CABLE ROUTING
The OC3 network card provides a connection from the AV8000 to the ATM backbone network
as a SONET-based fiber-optic User Network Interface (UNI). The OC3 network card has two
physical SONET interfaces on the front. The first interface provides the network connection.
The second interface provides Automatic Protection Switching (APS), which is a redundant
connection for the primary.
Route the fiber-optic cable:
1

Open the front access door to the cable tray as shown in the figure on page 43.
Do not look directly at the fiber-optic ports on the front of the OC3 network card
or into the end of any fiber-optic cable.
The minimum bend radius for a fiber-optic cable is 1.5 inches (38.10 mm). Do
not use a bend radius of less than 1.5 inches when looping the fiber-optic cable
in the cable tray.

Route the fiber-optic cable through the back of the AV8000 chassis and the open front
access door. Leave enough cable in the front to connect to the front panel connectors of the
OC3 network card.

If you implement APS, route a second fiber-optic cable through the back of the AV8000
chassis and the open front access door. Leave enough cable in the front to connect to the
front panel connectors of the OC3 network card.

Install Network Cards
Network cards provide an uplink interface to an ATM network. They supply both ATM traffic
management and physical layer functionality. Only one network card is required to provide a
link between the subscriber and the ATM backbone, but you can install a second network card
for redundancy or for dual homing. See “” on page 76 for more information about redundancy
and dual homing configurations. Network cards are typically placed in network card slots 11
and 12; however, 8xDS1 and 8xE1 cards must be placed in subscriber card slots 2-10 or 13-21.
Network cards can also provide a subscriber-side connection when used for subtending.
Subscriber-side means that the cards do not provide an uplink network connection, but provide
a connection downstream to another Avidia chassis that is being subtended. See “Subtending
Multiple Systems” on page 86 for more information about how to select and place network
cards for this application. For this type of application, the OC3 card can be placed in subscriber
card slots 2-10 or 13-21

Installing Cards into the AV8000

Install Subscriber Cards
Avidia subscriber cards provide two-way data communication with the subscribers.
Subscriber cards are currently available in several transmission technologies: ADSL,
cell SDSL, frame SDSL, and IDSL. You must select subscriber cards for the AV8000 that are
compatible with the subscriber-end equipment:
•

Select cell DMT ADSL subscriber cards to connect to cell-based DMT ADSL modems.

•

Select frame SDSL subscriber cards to connect to frame SDSL modems.

Cell subscriber cards operate with a data stream of fixed length. The advantage of this format is
that the network does not have to handle different sizes of packets or frames. This broadband
technology transmits data quickly and efficiently. There are three cell subscriber cards: AV541,
AV541-LP, and AV522.
Frame-based cards operate with a data stream of variable length. By using only a few bytes of
overhead, the frame format makes efficient use of each frame. This means that more of the
frame bandwidth is used for sending user data and less for overhead. Two Avidia cards are
available for frame-based data: AV421 and AV412.
The table below lists all the subscriber cards available for the AV8000 system.

You can install up to 18 xDSL subscriber cards, 8xDS1 network card(s), and 8xE1 network
cards in chassis slots S2 through S10 and S13 through S21. Install the subscriber cards (page 55)
into the chassis:

AV8000 Installation Manual

Chapter 6: Install Cards

How your Avidia system is configured determines which ADSL subscriber
card to use in the AV8000. Use the Avidia Model 541 (AV541) to connect to the
Avidia 8100. Use the Avidia Model 541-LP (AV541-LP) with network protection
to connect directly to an MDF.

Slide the card into a subscriber card slot (2 through 10 or 13 through 21). Ensure that the
retaining latches are lifted open.

Push the card in until the retaining latches touch the AV8000 chassis.

Gently close the retaining latches until they snap in place.

Tighten the captive screw on the top retaining latch.

Repeat Step 1 through Step 4 to install additional subscriber cards. Use any of the
remaining slots (2 through 10 and 13 through 21) for other cards.

What To Do Next

Install Blank Faceplates in Unused AV8000 Card Slots
Install blank faceplates in the AV8000 to cover unused slots. Unused slots
must be covered to prevent personnel contact with backplane connectors
under power and to maintain proper airflow within the chassis.

Select blank faceplates:
•

For a one-slot blank faceplate, use PN AVX121.

•

For a two-slot blank faceplate, use PN AVX122.

•

For a five-slot blank faceplate, use PN AVX125.

To install the required faceplates in your chassis, follow the procedure below:
1

Slide the blank faceplate into empty slot. Ensure the retaining latches are lifted.

Push the blank faceplate in until the retaining latches touch the AV8000 chassis.

Gently close the retaining latches until they snap in place

Tighten the captive screw on the top retaining latch.

AV8000 Installation Manual

Chapter 8: System Configuration for Special Applications

REDUNDANCY
Redundancy is a feature of the Avidia system. Redundancy includes:
•

dual homing, which provides redundancy at a VPC or VCC level (dual homing also
provides static load sharing) as described on page 78.

•

card redundancy, where a primary network card can switch to a secondary network card if
the primary card were to fail as described on page 79.

•

automatic protection switching (APS) for the OC3 network card with dual-PHY
connectors, where the primary physical port switches to the secondary physical port if the
primary port were to fail as described on page 80.

•

DS3 dual port redundancy, which provides both single and dual physical link port
redundancy, as described on page 81

AV8000 Installation Manual

Redundancy

Dual Homing
Through dual homing, a second network interface (DS3 or OC3 network card) is used in the
Avidia system and provides support that includes:
•

backup or redundant PVCs with the same destination.

•

static load sharing where traffic is directed separately to a primary and to a secondary
network card, increasing the amount of traffic that you can send through the system
(see page 79).

See the Avidia System Configuration and Management User Manual for information about
applying Quality of Service (QoS) to traffic that is assigned to dual homing configurations.
When setting up a system for dual homing, one network card is a primary network card and the
second network card is a secondary or backup network card. In an AV8000 system, you can
install the network cards into slot 11 and slot 12. The two network card slots are essentially
symmetric. At any point, only one of the two network cards will provide cell-bus clocking.
Configure ATM VPCs and VCCs to the network card that you choose as primary and configure
the backup VPCs and VCCs to the second network card.
In an Avidia 3000 system, you can install the network cards into slot 2 and slot 3. The network
card in slot 2 provides cell-bus clocking and must be in the slot when an Avidia 3000 system
is initialized (booted). When there is a failure of the network card in slot two, cell-bus clocking
switches to slot 1. Configure ATM PVPCs and PVCCs to the network card that you choose as
primary and configure the backup PVPCs and PVCCs to the second network card.
Redundancy is another feature of Avidia systems that uses two network cards. Redundancy
provides backup at a card level where dual homing provides backup at a PVC level (PVPCs and
PVCCs). See page 79 for more information about redundancy. You can implement both
redundancy and dual homing concurrently in an Avidia system. You must, however, carefully
plan traffic management and QoS to efficiently run the network. See the Avidia System
Configuration and Management User Manual for information about traffic management.

Backup ATM Connections
ATM service requires the configuration of ATM connections which comprise PVPCs and
PVCCs. PVPCs and PVCCs are the logical connections over which ATM cells are transmitted;
these are referred to as the primary PVPCs and PVCCs. You can create backup PVPCs and
PVCCs to which the system can automatically switch in the event that primary PVPCs or
PVCCs fail. These are referred to as secondary PVPCs and PVCCs. The secondary PVPCs and
PVCCs are configured to the second (redundant) network card in the Avidia system.

AV8000 Installation Manual

Chapter 8: System Configuration for Special Applications

Static Load Sharing
The dual homing feature of static load sharing allows you to increase the amount of traffic that
you can send through the system by allowing you to direct traffic to two separate network cards.
The uplink for both network cards (DS3 and OC3) is from the same ATM source, but the
information that is transmitted may be directed either to the same or to different destination
devices. The network cards can be of the same type (both OC3, for example) or they can be of
different types (an OC3 and a DS3, for example).
Through StarGazer or the Avidia command-line or Web interfaces, you can direct some Avidia
system ATM cross-connections to one of the network cards and then direct other ATM
cross-connections to the second network card. If you also implement card-level redundancy and
backup or secondary PVCCs and PVPCs, you need to carefully balance loads and manage
traffic and QoS to efficiently use the network and the bandwidth available for each network
card.
If one network card fails, the second network card takes over the functionality of the failed
network card, and re-establishes all the connections. This can result in too heavy a traffic load
on the second network card. To handle this, you can configure the recovery priority by traffic
type (for example, CBR first, rt-VBR second).

Network Card Redundancy
The Avidia system network cards provide two types of ATM connection redundancy:
•

connection redundancy between the network card and the destination ATM end system

•

network card redundancy, should a network card fail

Connection Redundancy—Network Card to ATM End System
When a connection goes down between the network card and the destination ATM end system,
the network card detects the failure and attempts to re-establish the connection by automatically
retrying or re-routing it, using signaling. This requires that the network card and the destination
ATM end system both support signaling.
To enable connection redundancy between the network card and the destination ATM end
system, you configure an end-to-end connection using SPVCs.
SPVCs comprise:
•

a cross-connect (PVCC or PVPC) from a cell-based subscriber card to a network card

•

an SPVC from the Avidia network card across the ATM network to an ATM end system

AV8000 Installation Manual

Redundancy

Network Card Redundancy
If a network card fails, and you have a second network card installed, the second network card
detects the failure, takes over all of the functionality of the failed network card, and
re-establishes all of the connections. This requires two ATM network cards to be installed in the
Avidia system, and at least two uplinks from the Avidia system to the ATM network.
Network card redundancy requires configuring static routes in the ATM Routing Table. When
a network card fails, the system uses the ATM Routing Table information to re-route SPVCs to
a specified slot and port on the secondary network card, based on the destination ATM address.
See the Avidia System Configuration and Management User Manual for information about
configuring static routes.

Managing Traffic for Redundancy
You can configure the Avidia system for static load sharing, using two installed network cards.
However, if one network card fails, the second network card takes over the functionality of the
failed network card, and re-establishes all the connections. This can result in too heavy a traffic
load on the second network card. To handle this, you can configure the recovery priority by
traffic type (for example, CBR first, rt-VBR second). If you do not configure recovery priorities,
the connections are recovered sequentially until no further resources are available. After that
point, the remaining connections are dropped. See “Static Load Sharing” on page 79 for more
information about static load sharing and traffic management.
When an initial call request is unsuccessful, or an existing connection fails, and the call has been
retried the maximum configured number of times, the call request is re-routed using the other
network card.

OC3 Automatic Protection Switching
OC3 network cards have two physical SONET interfaces, each with a transmit and receive port.
Under normal operation, all traffic is carried through the first interface; the second is not used.
Automatic Protection Switching (APS) uses the second interface to provide a backup to the first.
Avidia uses 1+1 unidirectional APS. In this version of APS, the primary interface is defined as
the working channel. The second interface is defined as the protection channel. Transmitted data
is sent over both channels. Data is normally received through the working channel. However, if
the working channel fails, received data automatically switches to the protection channel.
By default, APS is disabled on Avidia systems. You must enable APS for automatic switching
to occur. See the Avidia System Configuration and Management User Manual to enable and
configure APS.

AV8000 Installation Manual

Chapter 8: System Configuration for Special Applications

DS3 Dual Port Redundancy
When you use two DS3 cards in an AV8000 system, connect the cables as described in the
section “DS3 Interface Cables” on page 33 for one of the following modes:
•

single physical link mode (see figure on page 84)

•

dual physical link mode (dual homing) (see figure on page 82)

Dual Physical Link Network Card Redundancy
If a network card fails, and you have a second network card installed, the second network card
detects the failure, takes over all of the functionality of the failed network card, and
re-establishes all of the connections. This requires two ATM network cards to be installed in the
Avidia system, and at least two uplinks from the Avidia system to the ATM network.This
redundancy method is known as Dual Physical Link Port redundancy and is the default
redundancy mode.
Network card redundancy requires configuring static routes in the ATM Routing Table. When
a network card fails, the system uses the ATM Routing Table information to re-route SPVCs to
a specified slot and port on the secondary network card, based on the destination ATM address.

Implementing DS3 Port Redundancy
StarGazer allows network port redundancy to be implemented in either a Dual Physical Link
mode or a Single Physical Link mode.
Dual Physical Link Mode. In the Dual Physical Link mode, a DS3 card positioned in slot 11
of the AV8000 default to port 2 as the primary active link and a DS3 card placed in slot 12 of
the AV8000 defaults to port 1 as the primary active link. This default configuration allows both
cards to be activated simultaneously and carry network traffic over separate physical networks
links. In this mode, however, different active port numbers must be used for each DS3 network
card and both port 1 and port 2, on either card, must not be activated simultaneously.
If both DS3 cards and network links are active, then redundancy is provided by switching xDSL
traffic from the failed DS3 card or network link, to the remaining active DS3 card and its
associated network link. If only one DS3 card and link is active and the other DS3 card and
network link are idle, reserved for backup, then redundancy is provided by activating the idle
DS3 card and link and switching xDSL traffic from the failed DS3 card to the now active backup
DS3 card and its associated network link. In Dual Physical Link mode, the two network cards
are not required to be of the same media type—a DS3 card may be mixed with an OC3 card with
no reduction in functionality.

AV8000 Installation Manual

Redundancy

Dual Physical Link mode is the default port redundancy configuration, and is automatically
selected if Single Physical Link mode redundancy is turned-off during configuration of the DS3
cards. Redundancy of either type is a chassis-wide system configuration parameter involving all
of the installed network cards in a chassis.
Single Physical Link Mode. In the Single Physical Link mode, port redundancy requires
two DS3 cards—a DS3 card may not be mixed with an OC3 card, nor can two OC3 cards be
utilized in place of DS3 cards. However, if mixed OC3/DS3 cards must be used, then port
redundancy may only be configured for Dual Physical Link mode. As in earlier versions, use of
a single DS3 network card is allowed, although no port redundancy is possible under this
configuration.
Whereas the Dual Physical Link mode automatically activates port 2 for slot 11 and port 1 for
slot 12, by default, Single Physical Link mode selects the active port and slot through an internal
algorithm, that is in part, based on the user designation of either port 1 or port 2 as the
redundancy port during configuration.
The DS3 network card is configured for Single Physical Link mode redundancy through the
Web, command line or StarGazer interface. If Single Physical Link mode is turned-off, then
Dual Physical Link mode is assumed. Configuration procedures for setting up port redundancy
can be found in the DS3 Configuration sections of the Avidia software manuals.
The remainder of this section will describe the operation of dual port redundancy under both the
Dual Physical Link mode and the Single Physical Link mode configurations. The network
configuration will be examined both before and after a failure-induced automatic switch-over
of network traffic. If you decide to employ port redundancy in your system, you must pay
careful attention to your configuration and cabling.

DS3 Card Switch-Over—Dual Physical Link Mode
In Dual Physical Link mode, failure of one of the DS3 network cards (primary), or its associated
network link, will cause all xDSL traffic through that interface to be automatically switched to
the remaining DS3 network card (secondary) and routed over the alternate physical network
link. If the secondary physical network link is currently active, the traffic diverted from the
failed primary network card will be combined with the original traffic through the secondary
network card and its overall traffic load will be increased. This load increase is an important
consideration when selecting this port redundancy mode.
The following figure shows the before and after configuration of the network interface
following a failure in the DS3 card in slot 12 (primary) or a failure in the network link associated
with this card, where both the primary and secondary physical network links are active. Initially,
traffic is flowing through port 1 of the DS3 card in slot 12 (primary) to network link 1 and
through port 2 of the DS3 card in slot 11 (secondary) to network link 2. This is the initial default
configuration when operating in Dual Physical Link mode.

As mentioned earlier, although the secondary physical network link may be active, it may also
be maintained in standby mode and reserved strictly for backup purposes. In this case there will
be no increase in traffic load to the network after switch-over.

AV8000 Installation Manual

Redundancy

Although two DS3 network cards are shown in the preceding figure, Dual Physical Link mode
allows a configuration based on an OC3/DS3 network card combination. This is not the case
with Single Physical Link mode.

DS3 Card Switch-Over—Single Physical Link Mode
In Single Physical Link mode, failure of one of the DS3 network cards (primary) will cause all
xDSL traffic through that interface to be automatically switched to the backup DS3 network
card (secondary) and routed over the same physical network link. Since traffic diverted from
the failed primary network card will continue to be directed through the same physical network
link, any failure at the network level can not be corrected by using the Single Physical Link
mode—only DS3 card-level failures can be addressed and corrected by this method.
The figure below shows the before and after configuration of the network interface following a
failure in the DS3 card in slot 12 (primary). Initially, traffic is flowing through port 1 of the DS3
card in slot 12 to network link 1 and there is no traffic through port 2 of the DS3 card in slot 11
(secondary). Notice that in this case, the DS3 card in slot 11 is idle and that network link 2
connected to port 2 is not active. This is the normal dual network card configuration when
operating in Single Physical Link mode with port 1 selected for port redundancy. The software
port selection algorithm will reverse this active/idle card configuration if port 2 instead of port
1 is designated as the redundancy port.

link 1 is still directed through this same network link and there is no increase in network traffic
load.
Two DS3 network cards are shown in the figure above—this is the only configuration possible.
Single Physical Link mode requires that two DS3 cards be used in the network interface
configuration and does not permit an OC3/DS3 network card combination. If an OC3/DS3
network card combination is required, then the network interface must be configured as a Dual
Physical Link.

AV8000 Installation Manual

Subtending Multiple Systems

SUBTENDING MULTIPLE SYSTEMS
Multiple systems can be implemented, viewed, and managed as if they were one system.
This type of management is known as subtending. To subtend, connect and configure Avidia
systems in one of two ways: a star configuration or a daisy chain configuration.
In either implementation, multiple systems connect to one system that aggregates the
transmission of all the attached systems and provides one network uplink. The aggregating
system is known as the subtending or source system and each of the systems connected to it are
known as the subtended or destination systems.
See the figure below for a representation of both daisy chained and star configured systems. In
the figure, the subtending systems in each configuration aggregate the transmissions of the
subtended systems and provide a network uplink via OC3 to the ATM Switch.

Chapter 8: System Configuration for Special Applications

In the deployment of xDSL services, subtending helps the service provider satisfy the
customer’s demand for bandwidth against the WAN trunk capacities. Subtending helps
to expand the availability of service more cost effectively and expand to the more remote
subscribers. Subtending services, offered by Avidia, are complemented by its ATM features and
provide benefits such as:
•

optimizing the use of the more expensive WAN transmissions, such as DS1, DS3, and OC3,
by using only as much of the bandwidth as required

•

incrementally adding bandwidth without changing the hardware (for example, 8xDS1 and
8xDSX-1 cards have eight separately configurable DS1 ports)

•

using an Avidia system at the edge of the network (aggregates and provides uplink) rather
than using a third party switch

•

concentrating data efficiently

•

organizing the network through the use of VPCs and VCCs

•

selecting ATM QoS classes to effectively groom traffic within the network

Set up subtending using AV8000, AV3000 and AV2200 systems. AV8000 and AV3000
systems can both subtend and be subtended while the AV2200 is typically a subtended system
and does not subtend other systems. Then, within these Avidia systems, use the cards listed in
the following table to set up the appropriate subtending or subtended interfaces. To subtend,
connect a subscriber-side interface of the subtending system to the network-side interface of the
subtended system. A network-side interface must be in slot 11 or 12 of an AV8000, in slot 2 or
3 of an AV3000 or in slot 1 of an AV2200 to provide a cell bus clock and cell bus arbiter clock
for the Avidia system. The network-side interface also provides either the network uplink
interface to the subtending system or the network interface from the subtended to the subtending
system.

Chapter 8: System Configuration for Special Applications

It is important to note that you cannot use the same card to subtend and be
subtended. For example, a DS1 card has eight ports; you cannot use one port
to subtend another port on the same card.

The implementation of subtending is described in these sections:
•

“Star Management” on page 89

•

“Daisy Chain Management” on page 93

Each section provides both the features of and the limitations for implementing each subtending
approach. You can also combine the star and daisy chain approaches to effectively implement
subtending.

Star Management
In a star configuration, you can attach up to three systems (subtended systems) directly to the
one system that connects on the edge of the network (subtending system). The subtending
system aggregates the traffic from the subtended systems, switches all the traffic (its own and
that of the subtended systems), and provides the network uplink. Features of this management
approach include:
•

shorter segment costs rather than the longer length cost of a daisy chain

•

more cost effective than running fiber optic cable to new areas or to areas with a small
number of subscribers

Each system, whether subtending or subtended, can connect to and manage subscriber traffic
(modems).
“Star Physical Implementation” on page 89 shows how to set up a star configuration using
Avidia systems. “Star Configuration” on page 92 shows how to configure the system to
implement the appropriate connections.

Star Physical Implementation
The relationship of subtending in a star configuration is shown in the following figure.
The example shows an OC3 interface as the network uplink for the entire subtended system. An
AV8000 or AV3000 is the subtending system. Three chassis are subtended and are at three
separate physical locations (sites). The subtending connection is through a DS1 link.

Select the uplink card. Install one card for the
network uplink, such as the ATM switch shown to
the right, in the subtending system. The card must
reside in slot 11 or 12 for an AV8000 or slot 2 for an
AV3000. Select either a DS3, an OC3, or a
DS1/DSX-1 for an AV3000 or AV8000 system.

ATM
Switch

Select a card that accommodates the required
network uplink bandwidth for all the systems that are
aggregated by the subtending system. Ensure the
Network Uplink Connection
subtending system’s network uplink card is not a
bottleneck for traffic. For example, use an OC3 or
DS3 card for larger systems since these cards
provide greater bandwidth. Use a DS1/DSX-1 card for an initial implementation where Avidia
systems have only a few cards with the intention of expanding service in the future.

Daisy Chain Management
A daisy chain is a serial link (or cascaded link) of up to three systems that has one network
uplink connection and is viewed as one integrated system. A daisy chain is an approach for
managing systems to support subscribers who are physically separated by distance. The daisy
chain comprises:
•

one system functioning on the edge of the network to aggregate and switch ATM
transmissions and provide the network uplink

•

up to two systems functioning as access devices

Each system, whether subtending or subtended, can connect to and manage subscriber traffic
(modems).
“Daisy Chain Physical Implementation” on page 93 shows how to set up the daisy chain using
Avidia systems. “Daisy Chain Configuration” on page 95, shows how to configure the system
to implement the appropriate connections.

Daisy Chain Physical Implementation
The relationship of subtending in a daisy chain configuration is shown in the following figure.
Use two cards per system to connect a daisy chain. One card, used as a network-side interface,
connects to the next system upstream in the chain. Upstream connects toward the network
interface. The second card, used as a subscriber-side interface, connects to the next system
downstream in the chain.
The example shows an OC3 interface as the network uplink for the entire subtended system. An
AV8000 or AV3000 is the subtending system. The two chassis are subtended and are at two
separate physical locations (sites). The subtending connection is through a DS3 link.

MAINTENANCE

This chapter provides maintenance procedures for removing and replacing system components.
You can remove and replace any card, the fan tray, and the air filter on the AV8000 system
while the system is under power (hot swap). This means that the AV8000 is still in service when
you remove and replace any of these modules.
Never attempt to repair parts or modules yourself. Return all defective modules
to ADC for repair. See “Technical Assistance” on page 195
Always wear an antistatic wrist strap when removing and replacing
components in the AV8000. Refer to the section “Attaching an ESD Wrist Strap
to Chassis” on page 16.
NEVER power-up a fully loaded chassis. In all cases, remove all cards,

AV8000 Installation Manual

Chapter 10: ADSL Voice Shelves and POTS Splitters

AV8100 SYSTEM SPECIFICATIONS
The AV8100 voice shelf fits into a standard 23-inch Telco rack and comprises two parts:
•

•

voice shelf chassis with:
–

20 card slots

–

protection ground

–

interfaces for ADSL data in, POTS, and ADSL data stream out

up to 20 ADSL POTS splitter cards

The POTS splitter card, in the AV8100 voice, combines the incoming ADSL data from the
AV8000 integrated access concentrator with the analog voice signal (POTS) from a voice
switch. This multiplexed ADSL data stream is sent to the subscriber.
From the subscriber, the POTS splitter card receives multiplexed ADSL data from the
subscriber. This data stream is split into two signals: ADSL digital data and POTS voice signals.
The POTS splitter card sends the voice signal to the voice switch and the ADSL data to the
AV8000 integrated access concentrator.
ADSL data IN and POTS are intra-building lines and do not connect to outside
metallic tip and ring lines.

ADSL VOICE SHELF SPECIFICATIONS
The AV8100 voice shelf mounts in a 23-inch, 7-foot Telco rack. You can install up to seven
POTS splitter shelves in a Telco rack. Allow adequate space for cabling.
The following table shows chassis dimensions.

Avidia Cards and Chassis Power Requirements

AVIDIA CARDS AND CHASSIS POWER
REQUIREMENTS
Three types of cards are used in an AV8000 chassis:
•

management (page 146)

•

network (page 151)

•

subscriber (page 175)

A basic (minimal) AV8000 chassis, consists of:
•

one AMC management card—17 W

•

one DS3 network card—22 W or one OC3 network card—24 W

•

the cooling fan tray—18 W

The basic configuration above, having one OC3 card, will typically require 59 W.
If an additional DS3 network card or an OC3 network card is installed, then the typical power
requirements will increase to approximately 83 W.
Each 12-port ADSL subscriber card requires a maximum of 52 W when operational.
The IDSL (frame-based), SDSL (frame-based and cell-based) subscriber cards each require
29 W when operational.
The T1, E1, DS1and the DSX-1 cards each require 22 W when operational.
A typical loaded Avidia chassis, might consists of:
•

one AMC management card—17 W

•

two DS3 network cards—42 W or two OC3 network cards—48 W

•

the cooling fan tray—18 W

•

18 operational ADSL subscriber cards—52 W (each)

The configuration described above, having two OC3 cards, will typically require 1019 W.

Avidia Management Card

AVIDIA MANAGEMENT CARD
The Avidia 210 (AV210) management card, functioning as a Network Element (NE), provides
configuration and management communication for all interconnected network cards, subscriber
cards, and remote devices. Configuration and management for the AV8000 system occurs using
one of these interfaces:
•

command-line (on the management card)

•

Web (on the management card)

•

StarGazer Element Management System (a separate Avidia EMS software)

•

other SNMP-based management platforms

Always place the management card in slot 1 of an AV8000 chassis.

Master Agent SNMP Function
In the Simple Network Management Protocol (SNMP) master agent/subagent architecture, the
management card performs the master agent functions for other cards or devices in the Avidia
system that implement the subagent function (for example, subscriber cards).
The management card communicates with the StarGazer management system or other
SNMP-based management systems. For information about the MIBs that the management card
supports, see the Avidia System Configuration and Management User Manual.

AVIDIA NETWORK CARDS
Network cards provide an uplink interface to an ATM network. They supply both ATM traffic
management and physical layer functionality. Only one network card is required to provide a
link between the subscriber and the ATM backbone, but you can install a second network card
for redundancy or for dual homing. See “Redundancy” on page 77 for more information about
redundancy and dual homing configurations. Network cards are typically placed in network
card slots 11 and 12; however, 8xDS1 and 8xE1 cards must be placed in subscriber card slots
2-10 or 13-21.
Network cards can also provide a subscriber-side connection when used for subtending.
Subscriber-side means that the cards do not provide an uplink network connection, but provide
a connection downstream to another Avidia chassis that is being subtended. See “Subtending
Multiple Systems” on page 86 for more information about how to select and place network
cards for this application. For this type of application, the OC3 card can be placed in subscriber
card slots 2-10 or 13-21

OC3 Network Card
The OC3 network card provides uplink transmission at a rate of 155.52 Mbps and provides
connection to the ATM backbone network as a SONET-based fiber-optic User Network
Interface (UNI). It has two physical (dual-PHY) SONET interfaces, each with a transmit and
receive port. Under normal operation, all traffic is carried through the first interface; the second
is not used. For Automatic Protection Switching (APS), use the second interface to provide
backup to the first.
Three versions of the OC3 network card are available:
•

The AV311 OC3 network card provides a multi-mode, long-haul SONET connection.

•

The AV312 OC3 network card provides a single-mode, intermediate-range SONET
connection.

•

The AV313 OC3 network card provides a single-mode, long-range SONET connection.

Cabling
With an AV311 OC3 network card, use multimode fiber with SC fiber connectors. With an
AV312 OC3 intermediate-range (IR) network card or an AV313 OC3 long-range (LR) network
card, use single mode fiber with SC fiber connectors. Select an appropriate fiber-optic cable to

ATM Traffic
Types

The 8xDS1 network card supports these ATM traffic types:
• Constant Bit Rate (CBR) for digital information requiring continuous bit
streams.
• Unspecified Bit Rate (UBR) for LAN traffic.
• Real-time Variable Bit Rate (rt-VBR) for packetized voice or video that is not
transmitted at a fixed rate.
• Non-Real-Time Variable Bit Rate (nrt-VBR) for interactive transaction type
transmissions that are bursty and demand significant bandwidth only for
short periods of time.

Loopback

• Local loopback with signal being looped back within the network card at the
transceiver.
• Network loopback with signal received at the network interface and looped
back through the transmitter.
• Payload loopback with the card looping back to the payload (192 bits)
through the receive section (including the framer) and to the transmit
section, returning the payload and the newly-generated ESF framing.
• Remote loopback with the signal sent to the far end, where it is looped back.

164

AV8000 Installation Manual

Appendix A: System Specifications

In addition to the status LEDs, the front panel displays the following components:
•

T1 PORT SELECT pushbutton, when pressed, selects a port (1 through 8). Selection of any
port performs two functions: lights the corresponding LED and activates the associated
Bantam test jacks. When a port is deselected (no port), the port LED does not light, and the
Bantam test jacks remain inactive.

•

Bantam test jacks provide monitoring and direct access to the transmit and receive paths for
each T1 port (each with Tip and Ring signals):
–

The Equipment IN and OUT jacks provide direct access to the transmit and receive
signals of the active T1 port. The Equipment OUT jack supplies the transmitted output
signal from the active T1 port; the Equipment IN jack feeds the received input to the
active T1 port. A jumper cable connected between Equipment IN and OUT jacks
provides loopback to test the card functionality and to isolate malfunctions of the T1
card for the active port.

–

The Line IN and OUT jacks provide direct access to the transmit and receive line
signals from the active remote port. The Line OUT jack monitors the transmitted line
signal from the active remote T1 network interface port; the Line IN jack monitors the
received line signal to the remote T1 network interface port. A jumper cable connected
between Line IN and OUT jacks bypasses the T1 card, allowing isolation of a
malfunction of the network line function for the active port

–

The Equipment MON and Line MON jacks provide high impedance test points to be
used for monitoring (example, T1 test equipment). The Equipment MON jack provides
access to the T1 output. The Line MON jack provides access to the external line.

For information about running loopback tests on this network card, see the Avidia System
Configuration and Management manual.

conditions such as loop length, bridge taps, and noise level, to select the
highest data rate possible, up to the maximum you specified when configuring.
The rate-adaptive transmission range is:
• 600 kbps to 7 Mbps for downstream data (to subscriber)
• 64 kbps to 1 Mbps for upstream data (from subscriber)
The data rate resolution is 32 kbps both upstream and downstream.

system in north America. In Europe, the nearest equivalent
transmission facility is the E1.

A digital facility operating at 45 Mbps bandwidth. The T# or
equivalent DS-3 signal is composed of 28 DS-1 channels in many
cases.

TCP/IP

Transmission Control Protocol is a connection-oriented protocol
in which datagrams are divided when sent and reassembled
when received. This allows the different components of the
message to be routed differently to increase the speed of
transmission. TCP is a full-duplex, connection-oriented
end-to-end transport protocol running on top of IP

Appendix D: Glossary

TCP/IP

Transmission Control Protocol/Internet Protocols a protocol
used for communications between computers over networks and
the internet.

TDM

Time Division Multiplexing. A technique where data from
multiple channels is allocated bandwidth on a single wire pair
based on time slot assignment

Telnet

A program that allows you to connect to other computers over
the Internet.

Traffic Management. TM allows voice, video, and data to co-exist
on the same ATM network. Traffic Management methodology
permits the ATM network to provide different levels of QoS for
different customers and data types. TM also has the
responsibility for preventing congestion in the network and
thereby maximizing the network’s operating efficiency.

TFTP

Trivial File Transfer Protocol is a protocol used to download card
images or other files from an external TFTP server to the NVRAM
of any installed cards, or to upload files from an installed card to
an external TFTP server.

transparent LAN
service

Service offered by a provider that is used to connect LANs at
geographically separated sites. “Transparent” means that the
connection is invisible to the user and typically runs at the same
speed as the LAN.

twisted pair

Cable consisting of two 18 to 24 AWG (American Wire Gauge)
solid copper strands twisted around each other. The twisting
provides a measure of protection from electromagnetic and
radio-frequency interference.

U
UAS

Unavailable Seconds is the number of seconds during which the
line is unavailable.

UBR

Unspecified Bit Rate is a best-effort class of traffic, best suited
for Local Area Networks. When network congestion occurs, the
data is stored in a buffer until it can be sent.

UDP

User Datagram Protocol is a protocol in which datagrams are
sent whole and in the correct order.

UNI

User Network Interface. A standard defined by the ATM Forum
for access to public and private networks. A UNI connects an
ATM end system (such as a router) and an ATM switch. This is
also used for frame-relay. A UNI is the actual physical, electrical,
and functional demarcation point between the public network
service provider and the end user.

URL

Universal Resource Locator. Used with the World Wide Web as
an address.

upstream traffic

Communications from a user to a service provider.

UTP

Unshielded Twisted Pair. See CAT5.

224

VC or VCC

A Virtual Channel or Virtual Circuit Connection is a logical
connection in the ATM network over which ATM cells are
transmitted. Requires both VPI and VCI to identify a particular
cell traveling over this path.

VDSL

Very High Bit Rate DSL. Generally, this refers to 52 Mbps DSL
transmissions in one direction and 2 Mbps in the other
(asymmetric) over short distances. Typically, at around 1 Km,
speed is around 26 Mbps.

VP or VPC

A Virtual Path or Virtual Path Connection is a group of VCs
carried between two points. The VP/VPC provides a means of
bundling traffic traveling in the same direction. VPs and VPCs are
defined by a unique VPI value. Requires only a VPI to identify a
particular cell traveling over this path.

VPI

Virtual Path Identifier. An 8-bit field in the ATM cell header that is
used to identify a specific virtual path over which the cell is
traveling. It identifies a particular VP link.

xDSL

AV8000 Installation Manual

Digital Subscriber Line. Refers to a set of similar technologies
that provide high bandwidth over the copper twisted pair local
loop cable, without amplifiers or repeaters along the route. It is
compatible with existing services such as POTS, IDSN, and DDS
and will function over most of the current existing copper
infrastructure.
