ATM Feature Interactions
The following sec tions summarize the effec ts of ATM-WAN PNC on various 
features b ec ause of:
1. Loc ation assignments in a wid ely d istrib uted  switc h
2. Cell d elivery delays and rac e c ond itions that oc c ur on the ATM-WAN.
The features affec ted  b y these c ond itions are listed  in Ta b l e  B - 6
.
VDN in a Coverag e Path Enhances Call Coverage and  Call Vectoring  to allow you to assig n 
Vec tor Direc tory Numb ers (VDNs) as the last p oint in c overag e p aths. 
This feature is affec ted b y SVC setup  d elays and  failures.
VDN of Origin 
Announc ementProvid es ag ents with a short messag e ab out a c allers c ity of orig in or 
req uested  service b ased  on the VDN used  to p rocess the call. This 
feature is affec ted  b y SVC setup  delays and  failures.
Vis ua l ly  I m p a i r ed  
Attendant Service Allows a visually imp aired  attend ant to listen to voic ed  information 
ab out eac h b utton in Insp ect mod e. This feature is affec ted  b y SVC 
setup  delays and  failures.
Voi c e  Res p on se  
Integration Integ rates Call Vectoring  with the c ap ab ilities of voic e resp onse units 
(VRUs) such as the Lucent Technolog ies CONVERSANT Voic e 
Information System (CVIS). This feature is affec ted  b y SVC setup  
d elays and  failures.
Whisp er Page Allows station users to make and  rec eive barg e-in announcements to 
and  from other station users without anyone else on the calls being  
aware of the announc ements. This feature is affec ted  b y SVC setup  
d elays and  failures.
Wid eb and  Switc hing Provid es the ab ility to d edic ate 2 or more ISDN-PRI B-channels or 
DS0 endpoints for applications that require large bandwidth. This 
feature is affec ted  b y SVC setup  delays and  failures.
Wo r l d - C l a s s  To n e  
Detec tionAllows DEFINITY ECS to id entify and  hand le different types of 
c all-p rog ress tones. Affec ted b y d elays and  failures if the c all need s 
to g o to another EPN for the tone d etec tor.
Wo r l d - C l a s s  To n e  
GenerationAllows you to define c all-p rog ress tones. Affec ted b y d elays and  
failures if the c all need s to g o to another EPN for the tone g enerator.

Automatic  Call 
Distribution (ACD)X ATM WAN PNC p ermits the 
administration of a sing le ACD 
group  with agents sc attered  
ac ross the c ountry. Dep end ing on 
the servic e p rovid ed b y the WAN, 
this c an lead  to relatively long  
interc onnec tion d elays if, for 
example, an ACD c ustomer c alls 
in on a New York trunk and  is 
routed  to an ag ent on a p ort 
network loc ated  in Los Ang eles. Ensure that the ATM 
network used c an meet 
interc onnec tion d elay 
req uirements. This may 
req uire the use of loc al 
ATM switc hes 
interc onnec ted through 
d ed ic ated  long -haul 
fac ilities.The switc h 
c annot guarantee, in the 
worst c ase, that a talk 
p ath is availab le when the 
ag ent is alerted to the c all 
and  beg ins sp eaking . This 
remed y is nec essary if a 
switc h is to sup port ACD 
g roup s with ac c ess points 
in remote loc ations.
Automatic  Route 
Selec tion (ARS)X The multiloc ation feature provid es 
the ab ility to p erform ARS dig it 
c onversion and  routing  analysis 
based on loc ation. That is, the 
switc h c an sup port loc al p ub lic  
network d ialing p lans as 
app rop riate for users in eac h 
loc ation.Convert this c apab ility to 
ARS and ap ply it to UDP 
or AAR c alls.
Call Coverag e X When a c all is sent to remote 
c overag e, d igit analysis and 
routing  are b ased  on the loc ation, 
tenant numb er, and  p artition 
group  of the c overed  user, not on 
those of the c alling user. When the 
attend ant is spec ified as a 
c overag e point, the attend ant 
group  selec ted is b ased on the 
loc ation (or tenant p artition) of the 
c overed  user.
Call Forward ing X When c all forwarding  is ac tivated  
and a c all is ac tually forward ed , 
the forward -to dig its are analyzed , 
and the c all is routed, ac c ording  
to the loc ation, tenant p artition, 
and p artition g roup  assig ned to 
the forwarded  end point, not 
according to the caller’s 
prop erties and  p ermissions.

CAMA  trunks X Enhanc ed 911 (E911) servic e over 
CAMA trunks (MF sig nalling  
throug h a TN744D or TN2182B 
port) uses an algorithm that 
searc hes for a touc h-tone rec eiver 
within a sing le loc ation b efore 
searc hing  elsewhere. This ensures 
that an E911 c all uses a tone 
generator within the same loc ation 
as the trunk and  should  not 
negatively imp ac t E911 servic e on 
a WAN PNC c onfig uration. Eng ineer the servic e 
c irc uits and  p ort networks 
within a loc ation as if they 
were a stand-alone
