network

device.

At

least

one

of

the

physical

and

logical

loca

tion

connection

data

comprises

data

regarding

the

ID

of

a

logical

EFM

bonding

group.

The

physical

network

connec

tivity

data

in

another

example

comprises

device

data

that

identi?es the

existing

network

device

and

comprises

the

IP

address

or

node

number

of

existing

neighboring

network

device

to

the

newly

deployed

network

device.

It

is

possible

to

access

at

a

network

switch

a

Management

Information

Base

(MIB)

via the

Simple

Network

Management

Protocol

(SNMP)

to

determine

the

physical

network

connectivity

data.

A

determination

is

also

made

whether

the

network

man

ager

data

address

is

received

(block

16).

If

yes,

then

the

newly

deployed

network

device

transmits

to

the

network

manager

the

physical

network

connectivity

data

(block

18).

Provision

ing

data

is

received

from

the

network

manager

(block 20)

and

the

newly

deployed

device

is

provisioned

(block

22).

It

should

be

understood

that

it

is

possible

that

a

plurality

of

potential

network

addresses

for

the

network

manager

are

received

within

the

newly

deployed

network

device

and

the

newly

deployed

network

device

attempts

connection

to

the

network

manager

using

at

least

one

of

the

plurality

of

poten

tial

data

addresses.

If

a

determination

is

made

that

the

newly

deployed

network

device

does

not

receive a

network

data

address

for

the net

work

manager,

the

newly

deployed

network

device

announces

itself

by

transmitting

Layer

2

broadcast

messages

throughout

the

communications

network

(block

24).

A

deter

mination

is

made

if

the

broadcast

messages

were

successful

and

a

network

data

address

received

for

the

network

manager

(block

26).

If

yes,

then

the

received

network

address

for

the

network

manager

is

used

by

the

newly

deployed

network

device

to

transmit

the

physical

network

connectivity

data

(block

18).

If

no,

then

the

process

ends

in

this

one

example

(block

28),

but

in

other

examples,

the

process

could

loop

back

and

start

again.

In

accordance

with

a

non-limiting

example,

the

system

and

method

locates,

identi?es

and

provisions

a

newly

deployed

network

device.

An

illustrated

communications

system

that

is

a

high-level

diagrammatic

view

of

a

communications

system

40

is

shown

in

FIG.

2

in

order

to

illustrate

the

system

and

method

in

accordance

with

a

non-limiting

example.

As

shown

in

FIG.

1,

a

plurality

of

network

elements

(N

.E.)

42

are

formed

typically

as

network

switches

and/or

routers

and

form

the

communications

intemet

protocol

(IP)

network.

The

terms

switches

and

routers

are

sometimes

used

interchange

ably,

but

also

used

to

describe

Layer

2

and

Layer

3

function

ality.

The

switches

42

include

ports

with

various

network

devices

44

connected

thereto,

such

as

IP

phones,

computers

and

other

devices.

One

network

element

as

a

switch

in

this

example

is

shown

in

42a and

is

illustrated

with

components

in

greater

detail,

such

as

a

database

that

includes data

for

a

management

information

base

(MIB)

or

other

database

46,

transceiver

48,

and

various

ports

50

and

processor

52.

Other

components

of

such

network

devices

or

switches

as

known

to

those

skilled in

the

art

are

included,

but

not

shown

in

detail.

Each

of

the

network

elements

42

typically

include

such

com

ponents.

This

communications

network

40

includes

the

plu

rality

of

network

elements

as

switches

42

in

some

examples,

for

example,

Ethernet

switches,

that

are

connected

together

to

form

the

communications

network.

Many

of

the

network

switches

are

Layer

2

network

switches

and

each

typically

operates

in

conjunction

with

the

database

and

Management

Information

Base

(MIB)

46

such

as

illustrated

with

respect

to

the

switch

4211.

It

should

be

understood

that

the

term

switch

as

described

can

broadly

encompass

different

layer

switches,

routers

and

other

devices,

including

wireless

access

points.

Different

data

link

protocols

could

be

used

such

as

Ethernet

for

a

LAN,

PPP,

HDLC

and

ADCCP.

The

newly

deployed

network

device

is

shown

at

60

and

includes

functional

components

such

as

a

transceiver

62,

processor

64

and

database

66

and

could

also

operate

in

dif

ferent

functional

capabilities

including

router,

switch

or

other

device

and

include

various

ports

(not

shown).

In

accordance

with

a

non-limiting

example,

the

newly

deployed

network

device

60

propagates

the

discovery

proto

col

frame

to

the

at

least

one

existing

neighboring

network

device

4211

and

the

frame

includes

a

?eld

having

a

query

that

solicits

from

the

existing

neighboring

network

device

4211

the

physical

network

connectivity

data,

for

example,

using

the

steps

as

shown

and

described

relative

to

FIG.

1.

The

newly

deployed

network

device

60

receives

the

network

data

address

of

the

network

manager

70

and

transmits

its

physical

network

connectivity

data

to

the

remote

network

manager

70,

which

in

this

example,

is

shown

remotely

located

on

the

other

side

of

the

communications

network

40.

It

should

be

under

stood

that

FIG.

2

is

only

a

high-level

and

fragmentary

block

diagram

of

the

network.

For

example,

the

discovery

frame

could

comprise

a

?eld

having

a

query

for

inquiring

within

different

network

switches

or

devices

that

are

neighboring

whether

the

switch

or

device

receiving

the

frame

has

a

data

base

entry

regarding

the

Media

Access

Control

(MAC)

address

and

a

command

for

transmitting

back

physical

net

work

connectivity

data

from

the

neighboring

device

to

the

newly

deployed

network

device.

It

should

also

be

understood

that

the

network

40

can

be

established

to

use

link

bonding,

which

is

also

referred

to

as

Ethernet

bonding,

channel

bonding,

or

network bonding

in

some

examples.

This

allows

two

or

more

transmission

chan

nels,

such

as

communication

subscriber

line

pairs,

for

example,

in

an

XDSL

system

to

be

combined

at

the

symbol,

bit,

byte,

frame

or

?ow

level

for

creating

a

virtual

transmis

sion

channel

having

a

higher

bandwidth

than

a

single

trans

mission

channel.

The

bonding

across

multiple

communica

tion

line

pairs

also

termed

“links”

provides

Ethernet

over

Copper

(EoCu)

products

the

ability

to

create

high

bandwidth

communications

pipes

with

communication

of

Ethernet

and

similar

data

traf?c.

This

bonded

data

link

is

also

termed

Ethernet

in

the

First

Mile

(EFM)

and

typically

treats

the

multiple

copper

lines

as

a

uni?ed

physical

layer.

For

example,

the

IEEE

802.3ah

standard,

the

disclosure

which

is

hereby

incorporated

by

reference

in

its

entirety,

provides

an

ability

to

auto-detect

which

pairs

are

connected

between

two

devices

and

are,

therefore,

eligible

to

be

aggregated

into

a

single

Ethernet

connection.

Another

example

is

the

G.998.2

recom

mendation,

for

example,

as

applied

with

Single-pair

High

speed

Digital

Subscriber

Line

(SHDSL)

for

Ethernet-based

multi-pair

bonding,

the disclosure

which

is

hereby

incorpo

rated

by

reference

in

its

entirety.

It

should

be

understood

that

the

various

components

and

network

elements

shown

as

a

non-limiting

example

in

the

high-level

and

fragmentary

diagram

of

FIG.

2

can

include

a

bonding

engine

that

receives a data

string

to

be

communi

cated

to

a

customer

premises

(CP)

and

divides the

data

across

subscriber

lines

from

a

network

facility

such

as

a

central

of?ce

facility

to

the

customer

premises.

Similarly,

a

data

stream

to

be

communicated

from

a

customer

premises

(CP)

of

the

network

can be

received

by

the

customer

premises

bond

ing

engine,

which

devises

data

across

multiple

subscriber

lines.

The

network

bonding

engine

receives

such

data

and

reassembles

the

data

to

form

the

original

data

stream

received

and

divided

by

the

customer

premises

(CP)

bonding

engine.

In

a

network

facility

such

as

a

central

of?ce,

subscriber

lines

can

be

terminated

by

circuitry

residing

on

a

“line

card”
