Hardware Requirements
The following  hard ware is req uired  to imp lement AMIS analog  networking  and /or 
message delivery: 
nFo r  B o t h  Fe a t u re s : Suffic ient voic e p orts must b e installed  on the loc al 
system to hand le the ad d itional traffic . See the following  Vo i c e  Po r t  
Needs sec tion to d etermine if ad d itional voic e p orts may b e need ed . 
nFor Message Delivery: The rec ip ient must have a touc h-tone telep hone. 
Voice Port Needs
In ord er to d etermine if ad d itional voic e p orts may b e need ed  on your system to 
sup p ort the AMIS Analog  Networking  and /or Messag e Delivery features, first 
c onsid er the amount of traffic  (numb er and  leng th of messag es) you expec t to 
oc c ur d uring  the 
b usy hour of the d ay. 
nIf you d o not p lan to use the AMIS Analog  Networking  and /or Messag e 
Delivery features d uring the b usy hour (for examp le, if you p lan to allow 
messag es to b e transmitted  only at nig ht), you p rob ably have enoug h 
voic e p orts to sup p ort this feature. However, after the feature has b een 
ac tivated , you may wish to verify that system p erformanc e is not affec ted  
b y following  the step s in the Monitor Voice Port Use sec tion. 
nIf you p lan to use the AMIS Analog  Networking  and /or Messag e Delivery 
features d uring  the b usy hour, c onsid er the imp ac t of these features on 
voic e-port use as follows: 
— If the exp ec ted  AMIS analog  networking  and /or messag e d elivery 
traffic  is lig ht, you p robab ly d o not need  to ad d  any voic e p orts to 
sup p ort this feature. However, after the feature has b een ac tivated , 
you may wish to verify that system p erformanc e is not affec ted by 
following  the steps in the Monitor Voic e Port Use section. 
— If the exp ec ted  AMIS analog  networking  and /or messag e d elivery 
traffic  is heavy, d o the c alc ulations in the following  sec tion to 
d etermine the effec t these features may have on system 
performance. 
Calculate Expected Voice Port Use
If you p lan to use the AMIS Analog  Networking and /or Messag e Delivery features 
d uring the b usy hour and you want to estimate the imp ac t these features might 
have on your system p erformanc e, you c an d o the following  c alc ulations. (If you 
are p urc hasing  a new voic e mail system, the Luc ent Tec hnolog ies ac c ount team 
runs these calculations for you.) 
1. Estimate the numb er of AMIS analog  networking  and /or messag e d elivery 
messag es you exp ec t to oc c ur d uring  the b usiest hour of the d ay.

2. Estimate the antic ip ated  leng th of eac h messag e. Eac h AMIS and /or 
messag e d elivery messag e req uires an ad d itional 45 sec ond s of 
overhead  to transmit. 
3. Multiply the values from Steps 1 and 2 as follows: 
(# messag es) (averag e messag e leng th +  45 sec ond s) =  
X sec ond s of p ort use 
4. Divide the total sec ond s of projec ted p ort usag e b y 3600. This numb er 
represents the 
ad d itional p ort usag e req uired  to sup p ort this feature 
d uring the b usy hour. 
X sec ond s of p ort use / 3600 =  # ad d itional p ort usag e 
5. Add this number to the maximum average number of ports in use. Refer to 
the following  Monitor Voic e Port Use sec tion for the form and  field  
need ed  on your system to g et these values. 
6. Use the tab le in the ap p rop riate ad ministration manual (see next sec tion) 
to d etermine if the resulting  g rade of servic e (GOS) will b e ac c ep tab le 
(refer to the following  Monitor Voic e Port Use). If not, p lan to install the 
rec ommend ed number of add itional voic e p orts 
before imp lementing the 
AMIS Analog  Networking  or Messag e Delivery features. 
Monitor Voice Port Use
Use the following  p roc ed ure to d etermine if ad d itional voic e p orts may be 
need ed  on your system. You may use this p roc ed ure after ac tivating the AMIS 
Analog  Networking  and /or Messag e Delivery features to d etermine their imp ac t 
(if any) on system p erformanc e. 
nFo r  a n  A U D I X Sy st e m : 
1. Disp lay the traffic:feature:day
 form and record the number 
in the max averag e numb er of ports in use field . 
2. Using the
 AUDIX Ad ministration, 585-305-501, manual, c alc ulate 
the g rad e of servic e (GOS). 
3. Using the 
DEFINITY AUDIX System — Ad ministration, 585-300-507, 
manual, c alc ulate the g rad e of servic e (GOS). 
nFor an Intuity System: 
1. Disp lay the Feature Daily Traffic  form using  the list measurements 
feature day
 c ommand  and  rec ord  the numb er you see in the 
Maximum Average Ports in Use
 field . 
2. Calc ulate the g rad e of servic e (GOS). For p roc ed ures, searc h your 
Intuity d oc umentation for g rad e of servic e (GOS).
nFor any of the systems, a GOS of .05 is rec ommend ed  (a lower GOS is 
d esirab le). If the GOS is greater than .05, ad d itional voic e p orts should  b e

Security
Bec ause the AMIS Analog  Networking  and /or Messag e Delivery features use the 
switc h’s analog  lines to transmit messages, verify that the c lass of restric tion 
(COR) assig ned  to the loc al system’s voic e p orts sup p orts outc alling , or these 
features will not work. For examp le, to p rotec t ag ainst p ossib le toll fraud , the loc al 
system’s voic e p orts might be restric ted  from ac c essing  2-way or outg oing  trunk 
g roups. The COR for the voic e mail system mig ht need  to be altered  to allow the 
AMIS Analog  Networking , Messag e Delivery, and Outc alling  features to work. 
However, if left c omp letely unrestric ted , the AMIS Analog  Networking  and /or 
Messag e Delivery features c ould  allow loc al voic e mail users to send messag es 
to any valid  telep hone numb er world wid e. Conseq uently, the system 
ad ministrator must use jud gment when ad ministering the AMIS Analog  
Networking  and /or Messag e Delivery features. For examp le: 
nIn ord er to minimize exp osure to unauthorized  long -d istanc e c alls, the 
AMIS Analog  Networking  and  Messag e Delivery features should b e 
restric ted  to send ing  messag es to remote mac hines or telep hone 
numb ers loc ated  in sp ec ific  c alling areas or at the sp ec ific  d estinations 
needed to conduct business. 
nAdditionally, the system administrator c an use the Messag e Send ing  
Restric tions
 feature to limit the use of the AMIS Analog  Networking  and /or 
Messag e Delivery features to only those sub sc rib ers who have a need  to 
use it. The Message Send ing  Restric tions feature c an also b e used  to limit 
AMIS Analog  Networking  and /or Messag e Delivery c alls to sp ec ified  
remote mac hines (numb ers) or user c ommunities. It may b e overrid d en for 
sp ec ific  sub sc ribers if need ed . Refer to the feature d esc riptions manual 
for your voic e mail system for more information on the Messag e Send ing  
Restric tions feature.

Network Design
Planning  is the essential first step  in imp lementing  an AMIS analog  networking  
and /or messag e d elivery network. Ac tual network ad ministration should  not 
b eg in until the loc al voic e mail system is running  smoothly and the system 
ad ministrator is familiar with all asp ec ts of ad ministering  it. 
A network c oord inator should  b e named to manage the ad ministration and 
up d ates for every remote system (for AMIS analog  networking ) or telephone 
numb er (for messag e delivery). This is p artic ularly imp ortant on AMIS analog  
networking  and /or messag e d elivery networks where remote subsc rib er rec ord s 
must b e input manually on the loc al mac hine (mac hine-to-mac hine up d ates are 
not sup ported  over an AMIS analog /messag e d elivery network). 
Designing an AMIS Analog/Message Delivery
Network
Fi g u re  2 - 1 shows you a samp le network that c ontains the following  systems: 
nAU D I X Sys t e m :  This samp le R1V8 system uses AMIS analog  networking to 
c onnec t with a DEFINITY AUDIX system and  a set (rang e) of non-Luc ent 
Tec hnolog ies voic e mail systems. The system uses the Messag e Delivery 
feature to c onnec t to several other loc ations inc lud ing  all loc al numb ers 
and  one long -d istanc e d estination.
In this examp le, the AUDIX system is also d ig itally networked  to other 
AUDIX or Intuity systems. These d igital c onnec tions d o not d irec tly affec t

the Defining  Ad dress Rang es sec tion of this c hap ter. 
nDEFINITY AUDIX System: This system has a smaller number of 
sub sc rib ers. The system also connects to several Messag e Delivery 
loc ations inc lud ing  all loc al numb ers and  one long -d istanc e site, a rang e 
of non-Luc ent Tec hnolog ies voic e mail systems, and  the AUDIX R1V8 and  
Intuity systems. 
nIntuity System: The samp le Intuity system uses AMIS analog  networking  to

Defining Address Ranges
All loc al and  remote mac hines (inc lud ing  Messag e Delivery telep hone numb ers) 
in the AMIS analog /messag e d elivery network work must have uniq ue 
addresses. 
The p arts that make up  a remote mac hine’s ad d ress are the AMIS p refix 
(op tional), the ad d ress p refix (sometimes req uired ), and the extension ranges 
(req uired ). 
For non-Luc ent Tec hnolog ies systems or remote d estinations, you may need to 
c all the p erson resp onsib le for ad ministering  that mac hine to c ollec t add ress 
information. The ad d ress rang es for Luc ent Tec hnolog ies voic e mail systems c an 
be displayed using the following forms: 
nOn AUDIX systems, use the system:translation:address
 form. 
nOn DEFINITY AUDIX systems, use the List Add ress-Rang es form. 
nOn Intuity systems, use the List Ad d ress-Rang es sc reen. 
AMIS Prefix
An AMIS p refix may b e d efined  on the same form used  to imp lement the AMIS 
analog  networking  feature. If an AMIS p refix is ad ministered , loc al sub sc rib ers 
must always d ial it as the first p art of the rec ip ient’s ad d ress whenever they 
ad d ress an AMIS messag e (the p refix sig nals to the system that the following  
d ig its c onstitute an AMIS analog  networking  ad d ress). Even thoug h the AMIS 
p refix introd uc es another d ig it for subsc rib ers to d ial, you may wish to ad minister 
one to help  subsc rib ers d isting uish between AMIS messag es and  other features, 
and  to ensure that the ad dress rang es for the AMIS analog  network d estinations 
are uniq ue. 
Address Prefixes
Address prefixes are digits subscribers dial after the AMIS p refix (if one is 
ad ministered ) and  
prior to the rec ip ient’s extension or p hone number when 
addressing messages. Address prefixes may be provided to allow subscribers to 
ad d ress remote messag es in various ways and  still allow the messag e to b e 
delivered (for example, if the remote system c an be acc essed over a public 
or a 
p rivate network). 
Address prefixes may be 
req uired in some c ases to p revent extension rang es 
from overlap p ing ; dup lic ate or overlap p ing  rang es are not allowed  on AMIS 
analog  networking  or messag e d elivery networks (see the following  Overlapping 
or Dup lic ate Rang es sec tion for d etails). Generally, p refixes are 
not 
rec ommended in a DCS network.
