Introduction to Digital Networking
This c hapter p rovid es an introd uc tion to the b asic s of DEFINITY AUDIX d ig ital 
networking  and  d esc rib es some of the d igital networking features. The DEFINITY 
AUDIX system p rovid es two typ es of networking , d ig ital networking  and  AUDIO 
Messag e Interc hang e Sp ec ific ation (AMIS) analog  networking. Dig ital 
networking  p rovid es DEFINITY AUDIX sub sc rib ers with the ab ility to exc hang e 
voic e messag es with sub sc ribers on other DEFINITY AUDIX systems, Intuity
™ 
AUDIX systems, and  AUDIX R1V5 or later systems (c ollec tively c alled  AUDIX 
systems). AMIS analog  networking provid es DEFINITY AUDIX sub sc rib ers with 
the ab ility to exc hang e messag es with users of any voic e messag ing  systems 
that have AMIS, inc lud ing  non-Luc ent Tec hnolog ies systems that use the AMIS 
stand ard .
The information in this d oc ument is intend ed  for users of DEFINITY AUDIX dig ital 
networking . However, this c hap ter exp lains AMIS analog  networking  and  
c omp ares AMIS with d ig ital networking . Read  the information in this c hapter to 
und erstand  the networking  c ap ab ilities offered  b y the DEFINITY AUDIX system.
What Is Networking?
Loosely d efined , networking  is the transferring  of voic e messages b etween voic e 
messag ing  sub sc rib ers loc ated  on d ifferent systems. For the DEFINITY AUDIX 
system, there are two typ es of networking :
nDig ital networking
nAMIS analog  networking

1-2 What Is Networking? 
1
Dig ital networking  is d efined  as the transfer of a d ig ital file from one voic e 
mailb ox to another voic e mailb ox on a d ifferent system (DEFINITY AUDIX system, 
Intuity AUDIX system, or AUDIX R1 system). A voic e message is nothing  more 
than a d ig ital c omp uter file. The messag e is d ig itally rec ord ed  and  stored , then 
transferred  ac ross c ommunic ation lines. Just as two networked  c omp uter users 
c an send  files to eac h other, two AUDIX users c an rec ord  voic e messag es and  
send  the messag es to eac h other. 
Digital Networking Operation
Dig ital networking  op erates in the following  manner:
1. A loc al subsc riber rec ord s a message and  ad d resses the messag e to a 
remote subsc rib er using a loc ation p refix and  the sub sc rib er’s extension.
2. DEFINITY AUDIX d ig ital networking  d ials the numb er of the remote 
sub sc rib er’s system to which the message was ad d ressed .
3. The remote system answers the c all, and  the loc al system sends the 
messag e.
4. The remote sub sc rib er listens to the messag e and  hears a messag e 
head er that inc lud es the orig inating  system name, the orig inating  
sub sc rib er name, the time sent, etc .
5. The sub sc rib er who sent the messag e rec eives notific ation that the 
messag e was rec eived  and  op ened .
6. The remote sub sc rib er c an use the AUDIX voic e messag ing features to 
return a messag e to the orig inating  sub sc rib er, store the messag e, 
forward  the messag e, etc .
A system ad ministrator or installation technic ian must ad minister remote system 
information on the loc al system. For sub sc rib er information, DEFINITY AUDIX 
d ig ital networking  p rovid es the ab ility to share d atab ase information with remote 
DEFINITY AUDIX, Intuity AUDIX, and  AUDIX R1 systems. 
AMIS Analog Networking Operation
AMIS analog  networking  p lays messages as voic e files over analog  lines to 
c ommunic ate with other AMIS systems inc lud ing  other DEFINITY AUDIX 
systems, Intuity AUDIX systems, AUDIX R1 systems, and  non-Luc ent 
Tec hnolog ies systems that use AMIS. 
AMIS op erates in the following  manner:
1. A loc al subsc riber rec ord s a message and  ad d resses the messag e to a 
remote AMIS sub sc rib er.
2. The AMIS system d ials the numb er of the sub sc rib er’s system to whic h the 
messag e was ad d ressed .

3. The remote AMIS system answers the c all, exc hang es p rotoc ols with the 
loc al system, and allows the loc al AMIS system to p lay, not transfer, the 
messag e.
4. As the loc al system p lays the messag e, the remote AMIS system rec ord s 
the messag e in the sub sc rib er’s mailb ox (ind ic ated  b y the extension used  
when addressing the message).
5. The remote sub sc rib er c an listen to the messag e.

AMIS for DEFINITY AUDIX systems, Intuity AUDIX systems, and  AUDIX R1 
systems, inc lud ing  p lanning  and  ad ministration p roc ed ures. 
Why You Should Use Networking
Networking  enhanc es your DEFINITY AUDIX system in many ways:
nIf you have b usiness offic es in more than one g eog rap hic  loc ation, 
whether in the same build ing  or in d ifferent c ities, networking allows you to 
exc hang e voic e messag es with all loc ations as if they were one.
nIf you exc eed  the c apac ity of one AUDIX system at your loc ation, you c an 
network a DEFINITY AUDIX system with Intuity or AUDIX R1 systems so 
sub sc rib ers c an exc hang e messag es as if they were on the same system.
nMessage exc hange features inc lude:
— Name ad d ressing  — allows a sub sc rib er to ad d ress a messag e b y 
entering  a sub sc rib er’s name.
— Name b ac k — if a name is rec ord ed  for the remote subsc rib er, the 
system p lays the rec ord ed  name when a subsc rib er ad d resses a 
messag e to the remote sub sc rib er or when the sub sc rib er rec eives 
a message from the remote sub sc rib er.
— Ab ility to forward  messages to one sub sc rib er or a g roup  of 
sub sc rib ers, resp ond  to messag es, and  c reate g roup  mailing  lists. 
You c annot share mailing  lists ac ross the network.
nThe q uality of a voic e messag e sent b etween DEFINITY AUDIX systems 
and  b etween DEFINITY AUDIX systems and  Intuity AUDIX systems when 
using digital networking is the same as when the message was recorded, 
d ue to ad vanc ed  CELP-b ased  voic e messag ing  enc od ing  tec hnolog y, no 
matter how many times you forward  the messag e. 
AUDIX R1 uses the sub -b and  voic e messag ing  enc od ing  alg orithm. 
(CELP voic e messag ing  enc od ing  is a hig her q uality than sub -b and .) 
Messag es b etween DEFINITY AUDIX systems and AUDIX R1 systems are 
in sub-band format.
nSystem ad ministration for remote sub sc rib ers is simp le and  effic ient with 
the automatic  up d ate feature for sub sc rib er d atab ases.

nIf your b usiness op erates in different time zones, you c an send  or rec eive 
messag es any time of the day or night.
nThe DEFINITY AUDIX system c an network (AMIS and  d ig ital) to a 
maximum of 100 DEFINITY AUDIX, Intuity AUDIX, or AUDIX R1 remote 
systems with a maximum of 100,000 loc al and remote sub sc ribers. 
nPassword s and  uniq ue identifiers for eac h system p rovid e sec urity to the 
network. DEFINITY AUDIX d ig ital networking  uses a d ig ital protoc ol to 
exc hang e voic e messag es with other systems whic h also enhanc es 
system security.
nAMIS analog  networking  allows you to c ommunic ate with other voic e 
messag ing  p rod uc ts that d o not have the d ig ital networking  feature.
nAll a d ig ital networking  sub sc rib er need s to know to exc hang e voic e 
messag es with remote sub sc rib ers is the mac hine p refix and  remote 
sub sc rib er extension or, b y using  the name ad d ressing feature, just the 
sub sc rib er’s name.
Networking Terminology
Before you p roc eed with this d oc ument, you need  to know several terms related  
to DEFINITY AUDIX dig ital networking . Read  the terms and  their exp lanations in 
this sec tion to help  you und erstand  the tec hnolog y.
Local and Remote Machines
Mac hine is a term used  for AUDIX systems or other AMIS voic e mail systems. For 
DEFINITY AUDIX d ig ital networking , there are two typ es of mac hines, loc al and  
remote. Your mac hine is b oth a loc al and  a remote mac hine. To you, your 
mac hine is loc al b ec ause you are ad ministered  as a sub sc rib er on the mac hine. 
All other mac hines in the network app ear as remote mac hines to you. To 
someone at another loc ation, however, their mac hine is the loc al mac hine and  
your mac hine is the remote. Use the following explanation as you c ontinue with 
this doc ument:
nA loc al mac hine is the mac hine on whic h you are ad ministered  as a loc al 
sub sc rib er.
nA remote mac hine is any mac hine c onnec ted throug h the network with 
whic h your loc al mac hine exc hang es voic e messag es.
Remote mac hines d o not have to b e situated  in different g eographic al loc ations. 
If you have a larg e sub sc rib er p op ulation at a sing le site, you may req uire more 
than one AUDIX mac hine to hand le the c ap ac ity at that site. These multip le 
mac hines are networked  tog ether to p rovid e messag ing  c ap ab ilities to all of the 
sub sc rib ers. The remote mac hine usually is p lac ed  p hysic ally c lose to the loc al 
mac hine.

As you plan and  imp lement your network strateg y with the other network 
ad ministrators, rememb er that your mac hine is b oth loc al and  remote. All 
mac hines c onnec ted  throug h a d ig ital network req uire sp ec ific  information for the 
network to op erate p rop erly, suc h as mac hine names, p assword s, d ial p lans, and 
extension rang es.
Subscriber Types
To und erstand  DEFINITY AUDIX d ig ital networking , you need  to know the 
d ifferent typ es of sub sc ribers. Networking  ac tually has three sets of sub sc rib ers: 
loc al sub sc rib ers, non-ad ministered  remote sub sc rib ers, and  ad ministered  
remote sub sc rib ers. Loc al sub sc rib ers are the DEFINITY AUDIX users with voic e 
mailb oxes on your loc al mac hine. Non-ad ministered  and  ad ministered  remote 
sub sc rib ers are the users on remote mac hines.
Local Subscribers
Loc al subsc rib ers are the DEFINITY AUDIX users with voic e mailb oxes on your 
loc al mac hine. Ad minister the loc al sub sc rib ers as d esc rib ed  in 
DEFINITY AUDIX 
System Administration 
(585-300-507). You d o not have to c hang e loc al 
sub sc rib er ad ministration for networking . To other mac hines in the network, 
thoug h, the loc al sub sc rib ers on your mac hine are remote sub sc ribers. 
Coord inate all sub sc rib er ad ministration p roc esses with the other network 
ad ministrators. Chap ter 7, ‘‘Dig ital Network Planning’’
, help s you and  the other 
network ad ministrators c ollec t all the information need ed  to prop erly administer 
all sub sc rib ers.
Non-Administered Remote Subscribers
Th e  t e r m  non-ad ministered  remote sub sc rib er describes subscribers on remote 
mac hines in the network with whom loc al sub sc rib ers may b e ab le to exc hang e 
voic e messag es. There are three typ es of non-ad ministered  remote sub sc rib ers, 
as described below.
No-p rofile 
non-ad ministered  
remote sub scrib erA non-ad ministered  remote sub sc rib er who has never 
exc hang ed  voic e messag es with the loc al mac hine. 
Pr o f i le 
refers to a c ollec tion of remote sub sc rib er information, suc h 
as the mac hine name, sub sc rib er extension, p refix, and  
ad d ress, maintained  in the loc al mac hine’s sub sc riber 
d atab ase. For a no-p rofile remote sub sc rib er, the loc al 
mac hine datab ase does not c ontain any information.

Examp les later in this c hap ter show you how the three types of non-ad ministered  
remote subsc rib ers work with the network.
Administered Remote Subscribers
Th e  t e r m  administered remote subsc ribers describes any remote subscriber that 
has an ad ministered  profile on the loc al mac hine. The p rofile c ontains the 
following  information:
nThe remote sub sc rib er’s extension
nThe remote sub sc rib er’s name 
nThe remote sub sc rib er’s mac hine name
nA rec ord ing of the remote sub sc rib er’s name (op tional)
nA rec ord ing of the remote sub sc rib er’s mac hine name (op tional) 
Sinc e the loc al mac hine knows the remote sub sc rib er’s name and  has a 
rec ord ing  of the name, the mac hine sup p orts name ad dressing  for ad ministered  
remote subsc rib ers. When a sub sc rib er add resses a messag e to an 
ad ministered  remote sub sc rib er, the p erson hears the name of the remote 
sub sc rib er, if rec ord ed . If the name has not b een rec ord ed , the p erson hears the 
remote subsc rib er’s mac hine name, if the mac hine name has b een rec ord ed . If 
neither are rec ord ed , the p erson hears the extension p layed  b y the DEFINITY 
AUDIX system. Examp les later in this c hap ter show you how ad ministered  remote 
sub sc rib ers op erate with the network. Non-verified non- 
ad ministered  
remote sub scrib erA remote non-ad ministered  sub sc rib er who d oes not have a 
p rofile on the loc al mac hine, b ut has had a messag e 
ad d ressed  to them. The loc al DEFINITY AUDIX system 
c hec ks the d atab ase to d etermine if the ad d ress for the 
non-verified  sub sc rib er is valid  on any ad ministered  remote 
mac hines. If the loc al mac hine d etermines that the ad d ress 
is valid , the system attemp ts to send  the messag e. When 
the messag e is rec eived  b y the remote mac hine and  
d elivered  to the sub sc rib er, the loc al system c reates a 
verified  non-ad ministered  sub sc rib er p rofile. A sub sc rib er 
remains a non-verified  remote sub sc rib er only until the 
messag e is sent or returned.
Ve r if ie d  
non-ad ministered  
remote sub scrib erA non-ad ministered  remote sub sc rib er that has exc hang ed  
voic e messages with the loc al mac hine. After the loc al 
mac hine suc c essfully send s or rec eives voic e messages, 
the system c reates a p rofile for the non-ad ministered  
sub sc rib er. The p rofile c ontains the remote sub sc rib er’s 
extension and  mac hine name, but d oes not c ontain a 
rec ord ing  of the remote sub sc rib er’s name or the remote 
mac hine name. Name ad d ressing  and  voic e name-b ac k

Digital Networking Application Types
DEFINITY AUDIX digital networking provides different types of data connections 
b etween other DEFINITY AUDIX systems, Intuity AUDIX systems, and  AUDIX R1 
systems. The following  list introd uc es you to some of the p ossib le networking  
strateg ies availab le to the DEFINITY AUDIX system. The d esig n c enter, 
International Tec hnic al Assistanc e Center (ITAC), or Centers of Exc ellenc e (COE)

Loc al Networking A loc al network c onsists of one DEFINITY AUDIX system 
emb ed d ed  in the same switc h to whic h one or more Intuity 
or AUDIX R1 systems is attac hed . The networked  AUDIX 
systems ap p ear as one larg e voic e proc essing  system for 
most features. 
Remo te 
NetworkingRemote systems are usually loc ated  in d ifferent g eog rap hic  
loc ations, share or have uniq ue d ial p lans, and  may use 
several d ifferent typ es of d ata c onnec tivity.
Mixed  Networking A mixed network c onsists of a c omb ination of loc al and  
remote networking  or remote networking  and  may inc lud e 
any c omb ination of DEFINITY AUDIX, Intuity AUDIX, and /or

Data Connection Types
DEFINITY AUDIX d ig ital networking  p rovid es d ifferent typ es of network 
c onnec tions using the Dig ital Communic ations Protoc ol (DCP). Data c onnec tions 
serve both loc al networking  and remote networking , d ep end ing  on your system 
c onfig uration. The following  tab le b riefly d esc ribes the d ifferent typ es of network 
c onnec tions and  terms assoc iated  with the c onnec tions. These network 
c onnec tions are d esc rib ed  in d etail in later c hap ters.
The typ e of d ata c onnec tion you use dep end s on the fac ilities at your site and  
how you p lan to c onnec t with remote sites. You d o not have to use the same typ e 
of d ata c onnec tion for eac h AUDIX system to whic h the DEFINITY AUDIX system 
is networking .
Example of a Basic Network
The b est way to und erstand  DEFINITY AUDIX d ig ital networking  is to look at 
some examp les. The following  examp le shows a b asic  network whic h c ontains 
three mac hines, one loc al and  two remote. In the examp le, the loc al DEFINITY 
AUDIX dig ital networking  system is loc ated  in Denver, Colorad o, and  the remote 
systems are loc ated  in Columb us, Ohio, (AUDIX R1) and  Linc roft, New Jersey, 
(Intuity). DCP Mod e 1  An Luc ent Tec hnologies p rop rietary Dig ital Communic ations 
Protoc ol (DCP) c onnec tion using a d ata rate of 56 Kb p s. DCP 
Mod e 1 uses a DS1 fac ility on the switc h or a d ed ic ated  fac ility 
on a T1 c arrier.
DCP Mod e 2 DCP Mod e 2 is an async hronous, low-sp eed  (9600 or 19,200 
b p s) c onnec tion. DCP Mod e 2 uses a mod em/data mod ule or 
mod em/Async hronous Data Unit (ADU) arrang ement and  
c onnec ts over analog  or voic e-g rad e d ata lines.
DCP Mod e 3 A DCP c onnec tion using  a data rate of 64 Kb p s. DCP Mod e 3 
uses a DS1 or ISDN fac ility on the switc h or a ded ic ated  fac ility 
on a T1 c arrier.
The 19.2 Kb p s d ata rate only op erates on p rivate networks, not the pub lic  
network. If you d o not have a p rivate network and  need  to c ommunic ate throug h 
the p ub lic  network, async hronous networking  must op erate at 9.6 Kb p s. If 9.6 
Kbp s d oes not p rovid e the type of servic e you want for voic e messag ing , use 
one of the other typ es of d ata c onnec tions.
