There

now

follows

a

to

show

a

more

example

to

which

the

examples

as

described

can

be

applied.

FIG.

is

a

system

diagram

of

a

communica

tions

system

200

that

includes

various

network

components

and

devices

as

shown

in

FIG.

1

and

other

interconnected

platforms,

switches

and

servers.

It

should

be

understood

that

the

system

200

shown

in

FIG.

5

is

only

one

non-limiting

example

of

a

communications

system

that

can

be

used

with

the

methodology

as

described.

FIG.

5

shows

the

communications

system

that

includes

layer

2

and

layer

3

network

switching

functionality.

Typi

cally,

layer

2

switches

can

be

provided

such

as

the

NetVanta

1200

and

1500

series

switches

210

while

layer

3

Ethernet

switches

can

be

provided,

such

as

NetVanta

1300

series

devices

220

as

non-limiting

examples,

for

example,

the

Net

Vanta 1335

and

related

series

of

devices.

In

FIG.

4,

various

devices

such

as

a

1300

series

devices

by

ADTRAN,

INC.

are

illustrated

and

1200

series

devices

by

ADTRAN,

INC.

as

layer

2

devices

all

show

layer

2

and

layer

3

switching

and

functionality

in

this

non-limiting

example.

Switches

and

other

network

devices

as

illustrated

in

an

example

run

the

ADTRAN

Operating

System

(AOS)

and

provide

standards-based,

non-blocking

switching

and

sup

port

for

virtual

LAN’s

(V

LAN’s),

Quality

of

Service

(QOS),

and

Class

of

Service

(COS)

for

applications

such

as

VoIP,

link

aggregation,

advanced

management

and

remote

con?gura

tion

capability

and

other

functions.

The

devices

in

some

aspects

are

fully

managed

layer

2

and

layer 3

fast

Ethernet

switches

and

include

802.3af

Power

over

Ethernet

(PoE)

enabled

capabilities in

some

examples.

The

quality

of

service

capabilities

support

mission

critical

applications

such

as

VoIP.

A

WiFi

access

controller

manages

a

plurality

of

Wire

less

Access

Points

(WAP’s)

in

another

example.

These

Eth

ernet

switches

can

support

layer

2,

802.1p

Class

of

Service

(COS)

and

weighted

round

robin

and

strict

priority

queuing

for traf?c

prioritization.

At

layer

3,

a

multi-service

router

supports

various

markings

and

class-based

weighted

fair

or

low

latency

queuing.

As

noted

before,

layer

2

switches

can

be

stackable

POE

switches

with

gigabit

uplinks.

In

one

non-limiting

example,

a

Wireless

Access

Point

(WAP)

uses

a

NetVanta

150

wireless

access

point

(WAP)

or

NetVanta

1335

with

WiFi

that

provides

802.11

a/b/

g

radio

support

and

Virtual

Access

Points

(VAP’s)

and

segment

wireless

networks

together.

All-in-one

switch

routers

perform

services

such

as

switching,

IP

routing,

?re

wall,

Virtual

Private

Networking

(VPN),

and

802.11a/b/g

WiFi

in

a

single

platform.

A

NetVanta

1335

series

switch

integrates

a

modular

IP

access

router

and

24-port

PoE

layer 3

switch,

?rewall,

VP

and

appliance

and

wireless

access

in

a

platform.

Layer

2

switch-routers

can

be

all-in-one

access

platforms

such

as

the

NetVanta

1200

series

switch-routers

for

a

cost-effective,

single

box

approach

to

Voice

over

IP (VoIP)

migration.

Layer

3

switching

is

provided

in

one

example

for

VLAN

trunking

and

VGRP

for

802.1Q

VLAN

functionality

and

provide

separation

of

broadcast

domains

and

functional

work

areas.

Other

communications

servers

could

be

used

in

the

illus

trated

networks of

FIG.

such

as

a

NetVanta

7000

The

communication

servers

are

an

all-in-one,

o?ice-in-a-box

that

provides

voice

and

data

solutions,

including

Private

Branch

Exchange

(PBX)

functionality.

SIP

communications

are

used

to

various

remote

sites

having

communications

servers

such

as

IP

business

gateways

in

other

examples.

Any

communications

servers

could

be

formed

as

a

single

chassis

and

provide

a

LAN-to-WAN

infrastructure

and

Qual

ity

of

Service

(QoS)

that

maintains voice

quality

and

includes

a

Graphical

User

Interface

(GUI)

for

network

set-up

and

facilitate

installation

and

system

administration.

In

this

example,

a

communications

server

allows

a

converged

IP

voice

and

data

network

with

a

full-function

IP

PBX

for

voice

such

as

a

NetVanta

7000

series.

It

includes

an

integrated

Power

Over

Ethernet

(POE)

switch-router

for

data

in

an

inte

grated

device

and

aVirtual

Private

Network

(V

PN)

for

secure

internet

tunnelling.

The

device

enables

VoIP

by

providing

the

appropriate

functionality

that

includes

SIP-based

telephony

features,

voice

mail,

multi-level

auto-attendant,

caller

ID

name/number,

and

other

features

for

a

complete

VoIP

net

work.

The

device

includes

multi-site

SIP

networking

and

SIP

trunking

service.

Various

optional

modules

include

T1

and

ADSL

Network

Interface

Modules

(NIMs).

Analog

(FXS,

FXO)

Voice

Interface

Modules

(VIMs)

are

included

in

another

example

with

T1,

PRI

voice

interface

modules

and

?ber

SFP

modules.

A

communications

server,

in

one

example,

is

an

integrated

communications

platform

and

includes

capability

of

a

fast

Ethernet

switch

with

Gigabit

uplinks

and

expansion

slots

for

the

network

interface

modules

and

voice

interface

modules.

A

IP

telephone

system

as

part

of

the

communications network

200

as

illustrated

could

include

voice

mail

and

multi-level

auto-attendant,

caller

ID

name/number,

COS,

trunk

groups,

music-on-hold,

sales-on-hold,

overhead

paging,

and

other

call

options,

including

call

coverage

lists,

forwarding

of

calls

to

a

cell

phone

and

email

noti?cation

of

voice

mail.

Some

devices

can

operate

as

an

integral

SIP

gateway

with

the

appro

priate

FXS

and

FXO

analog

interfaces

to

support

analog

phones,

fax

machines,

modems

and

credit

card

readers.

An

integrated

voice

mail

can

include

3,000

or

more

messages

on

eight

ports

and

multi-level

auto-attendant

that

are

multi-level

on

eight ports

such

as

in

the

example

of

a

NetVanta

7000

series

device.

These

devices

include, in

one

example,

a

full

function

IP

access

router

and

an

integrated

state

inspection

?rewall

protects

against the

Denial-of-Service

(DOS)

attempts.

The

devices

include

IP

Sec

VP

and

tunnelling

with

DES/3DES/AES

encryption

and

an

SIP-aware

?rewall,

and

include

T.38

support

and

a

door

relay,

music-on-hold

(MOH)

interfaces

and

Voice

Quality

Monitoring

(VQM).

In

one

example,

SIP networking

is

supported

between

mul

tiple

locations.A

business

can

connect

multiple

sites

and

have

three

or

four

digit

dialing

and

local

call

routing

and

surviv

ability

and

on-net

calls

for

toll

bypass.

Multiple

SIP

trunks

allow

a

communications

server

to

connect

to

other

commu

nication

servers.

Remote

SIP

trunks

can be

supported

and

connect

to

all

endpoints

at

all

locations

such

that

a

user

can

have

local

voice

mail

and

auto-attendant

services.

A

hub

and

spoke

SIP

network

can be

accomplished

in

another

example.

A

dedicated

communications

server

can

aggregate

SIP

trunks

at

a

central

location,

which

for

quali?ed

applications,

increases the

number

of

other

communication

servers

that

can

be

networked

together.

The

user

can

use

an

Internet

Protocol

(IP)

phone

such

as

an

IP

700

series

of

telephones

with

different

line

versions

and

support

multiple

call

functions.

It

is

possible

to

incorporate

voice

mail-to-email

applications

and

personal

auto-attendant

in

which

each

phone

sets

up

their

own

automatic

attendant.
