An ad d ress p refix c ould  b e any of the following , or c omb inations of the following : 
nThe same numb ers as the c ountry c od e and  area c od e (for example, 
1 303
 within the United  States, or 011 44 71
 to reach London, United 
Kingdom). 
nThe same numb ers as the area c od e (NPA) and  offic e c od e (for example, 
614 555
). 
nThe offic e c od e (NNX or NXX) if the remote system shares the same area 
c od e (for examp le, 555
). 
nAn alphanumeric  c od e used  as a mnemonic  of a loc ation or system (for 
examp le, CB
 for Columbus). 
nAn RNX c od e if the remote system is in a p rivate network (for example, 8
). 
nThe AMIS p refix for AMIS ad d ress rang es only (for examp le, 7
). If an AMIS 
p refix is d efined , it must p rec ed e any other c harac ters sub sc rib ers must 
d ial in any other ad d ress prefixes d efined  for the AMIS ad dress rang es. 
nA Messag e Delivery prefix to help  sub sc rib ers d isting uish b etween 
Messag e Delivery messag es and  AMIS messag es (for examp le, 6
). A 
Messag e Delivery ad d ress p refix and  AMIS p refix c ould  b e the same, or 
two different p refixes c ould  be used . 
In ad dition to the ad d ress rang es that sp ec ify the d ig its that 
sub sc rib ers must 
enter (those that b eg in with an AMIS p refix, if d efined ), the loc al system also 
requires an address range that uniquely identifies the hunt group (callback 
numb er) of the remote mac hine (this is the voic e mail system numb er sent to the 
loc al mac hine from the remote system when inc oming  AMIS messag es arrive). 
This ad d ress rang e is need ed  to id entify this spec ific  remote system to the loc al 
system. If the remote mac hine has a different c ountry c od e, this ad d ress rang e 
must c ontain the c omp lete c allb ac k number (c ountry c od e, area/trunk c od e, and  
hunt g roup ). If the remote mac hine has a d ifferent area or trunk c ode, only the 
area/trunk c od e and  hunt g roup  are need ed  (the c ountry c od e should  b e 
omitted). If the remote system is loc al, only the hunt g roup  numb er should  ap p ear 
for that mac hine. If the remote mac hine c an b e ac c essed  throug h a p rivate 
network, the network-ac c ess c od e and  hunt group  for the remote mac hine 
should  ap p ear in the ad dress p refix list.

Overlapping or Duplicate Ranges
For all AMIS analog networking and message delivery addresses, duplicate 
ad d ress rang es or overlap p ing  ad d ress rang es are 
not p ermitted . A duplicate 
rang e
 (or full overlap ) means that the add ress rang e you have d efined  is alread y 
d efined  for another mac hine. An 
overlap p ing  rang e means that the range you 
have d efined  is a sub set of an alread y existing  rang e or is overlap ping  another 
rang e. 
For example, you would b e assig ning  a 
sub set if you tried  to assig n the extension 
rang e 2000-3999 when the rang e 2000-5999 alread y exists. The new rang e 
would  not b e allowed  (you would  rec eive an error messag e). You would  b e 
assigning an 
overlap if you tried  to assig n the extension rang e 5000-6999 when 
the rang e 2000-5999 alread y exists. To avoid  this p rob lem, assig n two new 
rang es instead  (1000-1999 and  6000-6999). If you c annot avoid  a d up lic ate or 
overlapp ing  rang e, return to theAddress Prefixes sec tion and selec t an add ress 
p refix that will make the range of numbers uniq ue. 
Extension Ranges and Length
Every remote mac hine in an AMIS analog /messag e d elivery network must be 
assig ned  an extension rang e. If you want loc al sub sc rib ers to ac c ess a sp ec ific  
remote mac hine or telep hone numb er (for examp le, for long -d istanc e AMIS 
c asual systems or Messag e Delivery d estinations), you c an assig n an extension 
“ range”  of a sing le numb er (suc h as 4000
 to 4000
). 
The leng th of the extension d ep end s on the ap p lic ation. For examp le, on AMIS 
one-step systems, the system d ials the remote system’s telep hone number for 
the subsc riber, allowing  sub sc rib ers to typ e fewer d ig its. The interac tion b etween 
extension length and  the 
d ial string (the numb er the loc al system d ials to reac h 
the remote mac hine) is summarized  in the next sec tion. Generally: 
nFor AMIS one-step  (p re-ad ministered ) c onnec tions: The extension leng th 
is typ ic ally the same leng th as other extensions on the switc h. That is, 
loc al sub sc rib ers’ extension numb ers are the same leng th as other 
extensions on the loc al switc h, and  remote sub sc rib ers’ extension 
numb ers are the same leng th as other extensions on the remote switc h. 
nFor AMIS two-step  (c asual) and Messag e Delivery c onnec tions: Th e  
extension length ind ic ates how many d ig its entered  b y sub sc rib ers for an 
AMIS or Messag e Delivery ad d ress are ac tually d ialed  b y the loc al 
system. For examp le, if the extension length is 7
, the loc al voic e mail 
system d ials the d ial string  followed  b y the last seven d ig its of the numb er 
a sub sc rib er enters as an ad d ress (an AMIS prefix, if assigned , is not 
d ialed ).

Dial String Interaction
Th e  dial string is either the first few d ig its d ialed  (for an AMIS c asual or Messag e 
Delivery setup ), or the entire number the loc al voic e mail system ac tually dials to 
reac h a remote mac hine (for a p re-ad ministered AMIS setup ). The d ial string  is 
op tional on AMIS c asual systems and  for message d elivery, but is req uired  for 
AMIS one-step  systems. The dial string  you ad minister dep end s in p art on the 
extension length. 
nFor AMIS one-step  (p re-ad ministered ) ad d ressing : A dial string is 
req uired. It c an b e up  to 65 c harac ters long , and  typ ic ally c onsists of the 
trunk-ac c ess c od e or dial-ac c ess c od e need ed  to reac h the p ub lic  or 
p rivate network, followed  b y the c omp lete telep hone numb er of the remote 
mac hine. For examp le, the loc al voic e mail system might d ial 
912015556000
 to reac h the remote system. 
If d esired , p ause c harac ters may b e inserted in the string  to have the 
system p ause b efore c ontinuing  to d ial (for examp le, to wait for a d ial 
tone). A sing le “ P”  (inc lud ing  q uotes) c auses the system to p ause 
ap p roximately 1.5 sec ond s; a “ P”  followed  b y a d ig it from 1 to 9 c auses 
the system to wait the sp ec ified  multip le of 1.5 sec ond s. 
nFor AMIS two-step  (c asual) and Messag e Delivery c onnec tions: The dial 
string  (if used ) may b e from 0 to 24 c harac ters long . It c onsists of any 
numb ers the system should  ad d  to the numb er sub sc rib ers d ial to reac h a 
sp ec ific  ad d ress. The d ial string plus the extension must b e less than or 
eq ual to 29 c harac ters. Some examp les are: 
— For a rang e of loc al numb ers, the d ial string  might b e 9
 (or 
whatever trunk-ac c ess c od e or dial-ac c ess c od e is assigned  to 
reac h the p ublic  network). For examp le, if the extension leng th is 7
 
and  a sub sc rib er sp ec ifies a valid  7-d ig it ad d ress (suc h as 
555-6000), the loc al system would  d ial 95556000
 to reac h the 
remote mac hine. 
— For a rang e of long -d istanc e numb ers, the d ial string  would  
normally b e 91
 in the United  States (the trunk- or d ial-ac c ess c od e 
followed  b y 1
). For examp le, if the extension leng th is 10
 and a 
sub sc rib er spec ifies a valid  10-d ig it ad d ress (suc h as 
201-555-6000), the loc al voic e mail system would  d ial 
912015556000
 to reac h the remote mac hine.

Sample Network Design
Tab le 2-1 summarizes the network planning information for the sample network 
configuration shown in Fi g u re  2 - 1 and  Fi g u re  2 - 2. As you stud y the tab le, use the 
following  information to help  you und erstand  the p lanning  information:
nLoc al System: The AUDIX system localr1
 was selec ted  as the loc al 
system in this examp le. Another form would  b e filled  out for the DEFINITY 
AUDIX system and  the Intuity system showing  those systems (named  
chicago
 and  newyork
 in the examp le) as the loc al systems, and  the 
AUDIX system as one of their remote voic e mail c onnec tions. 
nOne-Step  AMIS Connec tion: The c onnec tion to the DEFINITY AUDIX 
system (chicago
) and  the Intuity system (newyork
) is a p re-ad ministered  
(amisap
) c onnec tion. The loc al hunt g roup  for these p orts must b e either 
listed  on a sep arate line or inc lud ed  in another ad d ress rang e. The 
following  list shows ac c ep tab le p refixes for sub sc rib ers to d ial while 
ad d ressing messag es:
—7
— 7ch
— 7555
—8
—8ny
 
nTwo-Step AMIS Connec tion: The c onnec tion to the multip le non-Luc ent 
Tec hnolog ies voic e mail systems with 5-dig it ad d ress rang es from 55000 
to 58999 was ad ministered  for two-step  (amisac
) add ressing . The entire 
rang e is named  otherven
 (for 
other vend or). To reac h this set of systems, 
sub sc rib ers must always d ial the c omp lete voic e mail system numb er (for 
examp le, 7555-7000), p ress   then d ial a 5-d ig it extension to reac h a 
sp ec ific  remote rec ip ient. 
nLoc al Messag e Delivery: All loc al 7-d ig it p hone numb ers are availab le for 
loc al sub sc rib ers to use. Sub sc rib ers must enter the ad dress p refix 6
, 
followed  b y the c omp lete loc al numb er, to ad d ress a Messag e Delivery 
rec ip ient. 
nLong -Distanc e Messag e Delivery: In order to make it easier for loc al 
sub sc rib ers to plac e c alls to a Lond on offic e, the system ad ministrator has 
p lac ed  most of the overseas telep hone numb ers in the dial string . 
Subscribers need to enter just the address prefix 6
, followed  by the last 
three d ig its of the intend ed  rec ip ient’s ad d ress, in ord er to send  a 
messag e to Lond on. The loc al system ad ministrator has ad ministered  five 
memb ers of the Lond on offic e on the loc al mac hine to allow name 
ad d ressing and  name voic eb ac k.

Collect Remote Machine Information
Bec ause ad d ress rang es c annot c onflic t (no overlap s or d up lic ations are 
p ermitted ), you need  to c ollec t information ab out eac h remote mac hine or 
telep hone numb er you intend  to ad minister for AMIS analog  networking  and /or 
messag e d elivery. Usually this involves a p hone c all to the system ad ministrator 
or ind ivid ual resp onsib le for the remote mac hine or telep hone number you wish 
to ad d to your network. 
NOTE:
This step  is the most c ruc ial p hase in d esig ning  your network. If you have 
address range conflicts, you must assign unique prefixes to differentiate 
eac h mac hine. Whatever AMIS p refix and /or ad d ress p refixes you assign 
must b e c ommunic ated  to the sub sc rib er p opulation so sub sc rib ers c an
