who use TTYs. The Multiling ual feature makes it possible to 
p rovid e the TDD announc ement set on the same DEFINITY 
AUDIX system as voic e announc ement sets, satisfying  the 
messaging needs of both groups of users with one system.nThe TDD announc ement set c an

Applications
Use of the TDD announc ement set enab les emp loyers to c omp ly with the 
Americ ans With Disab ilities Ac t (ADA) b y making  reasonab le ac c ommod ations 
for hearing-imp aired  emp loyees. (Cost-c onsc ious emp loyers should  note that a 
sing le Multiling ual DEFINITY AUDIX system is able to ac c ommodate the need s of 
voic e-mail users who req uire a sp oken announc ement set and  hearing -imp aired  
users who req uire a TDD announc ement set.) All that a sub sc rib er or c aller 
need s is a standard  stand -alone, ac oustic ally-c oupled  TTY along  with a 
touc h-tone telep hone. Both the touc h-tone keyp ad  and  the TTY keyb oard  are 
need ed  for TDD c ommunic ations with the DEFINITY AUDIX system. 
Considerations
There are a numb er of c onsid erations for using  the TDD announc ement set with 
the DEFINITY AUDIX system. 
nName Record by Subscriber: Any user who interac ts with the DEFINITY 
AUDIX system primarily using  a TTY should  rec ord their name using  a 
TTY. TTY users have 12 sec ond s to type in their name. The system 
ad ministrator should  not voic e the names of TTY users. 
nA d m i n i s t ra t o r  TTY: In some situations, the system ad ministrator may need  
to rec ord  g reetings, messag es, names, and  c ustom announc ements for 
TTY users. To rec ord  these, the system administrator need s a TTY; a TTY 
with a b uffer is rec ommend ed  sinc e the system ad ministrator may need  to 
ed it g reeting s, messag es, and  announc ements b efore d ownload ing  them 
to the DEFINITY AUDIX system. (See the user’s g uide that c omes with the 
TTY for instruc tions on using  the TTY.) It also is rec ommend ed  that the 
TDD announc ement set be running  when rec ord ing  TTY g reeting s, 
messag es, and  announc ements. 
nGo Ahead: A stand ard  abb reviation in TTY c ommunic ations, known by all 
exp erienc ed  TTY users, is 
GA. This stand s for Go Ahead  and  means, in 
essenc e, It’s your turn to transmit. The GA p romp t is p art of the DEFINITY 
AUDIX TDD announc ement set and  is used  in p lac e of the aud ib le tone 
that follows rec ord  at the tone in the sp oken announc ement set. 
nMod e sync hronization p rob lems and  solutions: TTYs use the Baudot 
c ommunic ations p rotoc ol in whic h the same five-b it c od e c an rep resent 
either a letter or a non-alp hab etic  c harac ter, suc h as a numb er or fig ure. 
(For examp le, the binary c od e 00001 is both the letter E and  the numb er 
3.) This sharing  of five-b it c od es is mad e p ossib le b y having  two mod es, a 
letters mod e and  a numb ers/fig ures mode. 
If a rec eiving  TTY is set to letters mod e (b y rec eiving  the five-bit c od e 
11111), then the TTY assumes all sub seq uent five-b it c harac ter c od es 
rec eived  are letters. By c ontrast, if a rec eiving TTY is set to 
numb ers/fig ures mode (b y rec eiving  the five-b it c ode 11011), then the TTY 
assumes all subseq uent five-b it c harac ter c od es rec eived  are numbers

293 Considerations 
and  fig ures. This is imp ortant: when a TTY is not in the same mod e as the 
d evic e that is transmitting  to it, the c harac ters that d isp lay on the rec eiving  
TTY will make no sense to the user. 
All DEFINITY AUDIX TDD announc ements c ontain the ap p rop riate mod e 
reset c od es to ensure that the rec eiving  TTY stays mod e-sync hronized  
with the DEFINITY AUDIX system d uring  announc ement p layb ac k. It is, 
however, the user’s resp onsib ility to ensure mod e sync hronization when 
rec ord ing  names, g reeting s, messag es, and  c ustom announc ements. 
nMod e sync hronization when rec ord ing  g reeting s, messag es, names, and  
c ustom announc ements
: TTY users should  follow these g uid elines when 
rec ord ing  g reeting s, messag es, names, and  c ustom announc ements to 
keep  the rec eiving  TTY in the ap p rop riate mod e. 
Some TTYs have b oth a letters key and  a numb ers/fig ures key for 
switc hing  to the ind ic ated  mod e. If the first c harac ter in your rec ording  is a 
letter, p ress the letters key b efore you typ e anything  else; or, if the first 
c harac ter in your rec ord ing  is a numb er or fig ure, p ress the 
numb ers/fig ures key b efore you typ e anything  else. 
Most TTYs do not have a letters key and a numb ers/fig ures key. If you d o 
not have sep arate letters and  numb ers/fig ures keys, sync hronization of 
mod es is more inc onvenient but c an b e ac c omp lished  in the following  
way: 
— If the first c harac ter you need to typ e is a letter, enter a slash (/); 
then p ress the sp ac e b ar a few times b efore you start typ ing . This 
c auses the system to reset to letters mod e. 
— If the first c harac ter you need to typ e is a numb er or fig ure, typ e x
; 
then p ress the sp ac e b ar a few times b efore you start typ ing . This 
c auses the system to reset to numb ers/fig ures mod e. 
nGeneral g uid elines on g enerating  g reeting s and  c ustom announc ements: 
TTY users need  to use b oth the TTY keyb oard  and  the touc h-tone 
telep hone keyp ad . The instruc tions c ontained  in c ustomized  
announc ements and  mailb ox g reeting s must make it c lear whic h devic e to 
use. You mig ht want to use 
dial when the user need s to use the telep hone 
keyp ad  and  
typ e when the user need s to use the TTY keyboard . 
When using  a TTY to typ e d irec tly to the DEFINITY AUDIX system, the 
DEFINITY AUDIX system c aptures and  p reserves any hesitations in 
typing s, missp elling s, and  so on. For this reason, it is rec ommend ed  that 
system ad ministrators use a TTY with a b uilt-in b uffer and c ompletely ed it 
the g reeting  or announc ement b efore c alling  the DEFINITY AUDIX system 
to d ownload  the b uffer. See your TTY user’s g uid e for instruc tions on 
ed iting  and  d ownload ing the TTY b uffer. 
nTransmission Prob lems: If TTY users see what they c onsider to be more 
than the normal numb er of typ ing  errors in information d isp layed  b y the 
DEFINITY AUDIX system, the transmission from the DEFINITY AUDIX 
system may b e too soft. Dial   to make the transmission loud er.

294 Considerations 
If the DEFINITY AUDIX system d oes not pic k up  the touc h-tone key 
p resses, transmission with the DEFINITY AUDIX system may b e too loud. 
Dial   to make the transmission softer. 
nHandset Ad ap tor: Certain telep hone hand sets, suc h as the R-typ e 
hand set used  on many Luc ent Tec hnolog ies b usiness telep hones, will not 
work reliably with TTY ac oustic  c oup lers that were intend ed  for more 
trad itional typ es of hand sets. The Luc ent Tec hnolog ies Sp ec ial Need s 
Center is ab le to p rovide ad ap tors. Contac t your Luc ent Tec hnolog ies 
Ac count Executive. 
nCorrec ting  inap p rop riate mod e shifts: A receiving TTY may be placed in 
the wrong  mod e und er the following  c irc umstanc es: 
— The TTY user d ials ahead  or d ials throug h an announc ement 
rec eived  from the DEFINITY AUDIX system. 
— A TDD message or greeting rec eived from the DEFINITY AUDIX 
system was rec ord ed without ap p rop riate reset c od es. 
Althoug h this prob lem c an b e annoying , resetting  the rec eiving  TTY to the 
c orrec t mod e is a fairly straig htforward  p roc ess. On TTYs that have 
sp ec ific  mod e-reset keys, press the ap prop riate key. Do the following  on 
TTYs that d o not have mod e-reset keys: 
— Typ e any number or fig ure to shift a TTY that is in letters mod e to 
numb ers/fig ures mod e. 
— Typ e any letter to shift a TTY that is in numb ers/fig ures mod e to 
letters mod e. 
nBroad c ast Announc ement: A hearing -impaired  user who uses only a TTY 
for c ommunic ations with the DEFINITY AUDIX system will not see anything  
on the TTY for a voic ed  b road c ast message. The system ad ministrator 
may want to send  a TDD messag e to TTY users informing  them of the 
following : 
— They will rec eive a voic ed b road c ast announc ement and  they 
should  d elete this message 
— The c ontents of the b road c ast message

295 Requirements 
nLog in Announc ement: A hearing-imp aired  user who uses only TTY for 
c ommunic ations with the DEFINITY AUDIX system will not see anything  on 
the TTY for a voic ed  log in announc ement. If there are TTY users on the 
DEFINITY AUDIX system, it may b e a g ood  id ea not to use the Log in 
Announc ement feature. If a log in announc ement is going to b e used , the 
system ad ministrator may want to send  a TDD messag e to TTY users 
informing  them of the following : 
— They will rec eive a voic ed log in announc ement when they log  in, 
and  they will have to wait several sec ond s for a TDD promp t b efore 
c ontinuing  with their DEFINITY AUDIX session 
— The c ontents of the log in announc ement 
Requirements
The following are req uirements for using  the TDD feature: 
nThe p urc hasab le TDD announc ement set must b e installed . If the TDD 
announc ement set is used  on the same DEFINITY AUDIX system as voic e 
announc ement sets, the Multiling ual feature must b e turned  on for the 
system. 
nTo rec ord  TDD g reeting s and c ustom announc ements, the system 
ad ministrator need s a TTY; a TTY with a b uffer is rec ommend ed  sinc e the 
system ad ministrator may want to ed it the g reeting b efore d ownload ing  it 
to the DEFINITY AUDIX system. (See the user’s g uide that c omes with the 
TTY for instruc tions on using  the TTY.) 
nEac h sub sc rib er or c aller who wishes to c ommunic ate with the DEFINITY 
AUDIX system need s a stand ard  stand -alone, ac oustic ally-c oup led  TTY 
and  a touc h-tone telephone. Devic es that b ypass the touc h-tone keyp ad , 
suc h as c omp uters with nond ialing  TTY mod ems, are unab le to issue 
c ommand s to the DEFINITY AUDIX system. 
nThe TDD announc ement set need s to b e id entified  on the Class of Servic e 
sc reen or the Sub sc rib er sc reen for eac h TTY user. 
Feature Operation
Assig n the TDD announc ement set to sub sc rib ers either on the Class of Servic e 
sc reen or on the Sub sc rib er sc reen. The TDD announc ement set c an b e the 
Log in Announc ement Set, the Call Answer Primary Announc ement Set, or the 
Call Answer Sec ond ary Announc ement Set. 
Callers who reac h the mailb ox of a sub sc rib er with only the TDD announc ement 
set ac tive must use a TTY to interac t with the DEFINITY AUDIX system. DEFINITY 
AUDIX feature operation is the same for TTY callers as for speaking c allers with 
minor d ifferenc es as noted  in this feature d esc rip tion.

297 Feature Operation 
Multilingual Feature
There are several c onsid erations when dec id ing  how to ad minister the 
Multiling ual feature and c all c overag e for the hearing -imp aired  TTY user. For 
examp le: 
nDo you exp ec t the hearing -imp aired  p erson to rec eive voic e c alls? 
nDoes the p erson have suffic ient hearing  ab ility to listen to voic e 
messag es? 
nIs your c omp any able to p rovide c all c overag e to a TTY translator servic e 
for hearing-imp aired  users who c annot listen to voic e messag es? 
Sub sc rib ers who p rimarily use the TDD announc ement set should  rec ord  their 
name using  the TTY. If a sub sc rib er need s to rec eive b oth TTY and  voic e c alls, it 
is rec ommended , b ut not nec essary, that two sep arate telep hone numb ers b e 
assig ned  to the sub sc rib er — one for TTY c alls and  one for non-TTY c alls. 
It may b e more p rac tic al to set the Multilingual feature Call Answer Lang uage 
Choice field to n (no) on the Subscriber or Class of Service sc reen unless both 
the p rimary and  sec ond ary announc ement sets are TTY-b ased  (suc h as U.S. 
Eng lish TTY and  another TTY-b ased  lang uag e whic h may be availab le in the 
future). 
In the example below, Mary Jones has no hearing and does not speak; and her 
c omp any has an in-house TTY translation servic e to hand le inc oming  voic e c alls. 
The Call Answer Lang uag e Choic e field  is set to n (no) for Mary, and  she has one 
p ersonal g reeting  whic h inc lud es b oth voic e and  TTY. 
The system ad ministrator, or another sp eaking  p erson, rec ord s the first p art of 
Mary’s p ersonal g reeting  whic h is very short. If the TDD announc ement set is the 
Log in Announc ement Set for Mary Jones, the g reeting  p romp ts are in TDD; in 
whic h c ase, the sp eaker removes the hand set from the TTY ac oustic  c oup ler 
when the GA p romp t d isp lays on the TTY, voic es the g reeting , and  then returns 
the hand set to the ac oustic  c oup ler either to rec ord  the TDD p art of the g reeting  
or to wait for more promp ts. 
The following c ould  b e the voic e part of a g reeting  rec orded  for Mary Jones: 
“ This mailb ox b elong s to a hearing -imp aired  user, Mary Jones. To leave a voic e 
messag e, press zero now.”
Pressing  zero would  send  the c aller to the extension of a hearing  p erson who c an 
transc rib e voic e messag es to TTY messag es and send  them to the mailb ox of 
Mary Jones. The transc rib er need s to b e ad ministered  as a c overing  extension 
on the Sub sc rib er sc reen for this arrang ement. The sec ond  p art of Mary’s 
p ersonal g reeting  is in TDD, rec ord ed  b y Mary or the p erson who rec ord ed  the 
voic e p art of the g reeting . The TDD p art of the g reeting  need s to b e rec ord ed  
d uring the same rec ord ing  session as the voic e p art. (In other word s, Mary’s 
g reeting  c ontains both a voic e p art and  a TDD part. The voic e p art is first and

very short so that it d oes not c ause a long  d elay in the TDD g reeting  seen b y the 
TTY c aller. The TDD p art immediately follows the voic e p art.) 
The ab ove examp le illustrates one p ossib le sc enario for ad ministering  the TTY 
user. The system ad ministrator should  c onsid er the TTY user’s need s, the 
req uirements of his or her job , and  c all c overag e c ap ab ilities for the TTY user 
availab le at your c omp any. 
Interactions with Other Features
This sec tion id entifies the interac tions of the TDD feature with switc h features and
