Processor Occupancy Reports
The term Proc essor Oc c up anc y (or simp ly, Oc c up anc y) is d efined  as the 
p erc entage of time the switc h p roc essor is b usy p erforming  c all p roc essing  
tasks, maintenanc e tasks, ad ministration tasks, and  op erating  system tasks. As a 
c ontrast, the p erc entag e of time the p roc essor is not used  is referred  to as Id le 
Occupancy.
The primary objectives of the proc essor occupanc y reports are:
nTo p rovid e a summary of c ustomer usag e d ata so p roc essor oc c up anc y 
and  availab le c ap ac ity c an be d etermined .
nTo d isp lay, on a per time interval b asis, the p roc essor oc c up anc y and  
assoc iated  c alling  rates whic h fac ilitates the isolation of c ertain c ustomer 
reported problems.
There are five d ifferent p roc essor oc c up anc y c ommand s:
nlist measurements occupancy summary
nlist measurements occupancy last-hour
nlist measurements occupancy busiest-intervals
nlist measurements occupancy pktint (G3r only)
nlist measurements communications-links
The first three c ommand s p rovid e p roc essor oc c up anc y d ata and  assoc iated  
c all traffic  for d ifferent measurement intervals. The p ktint report p rovid es 24 hours 
of oc c up anc y d ata for eac h of the p roc essor p ac ket interfac e (p ktint) b oard s in 
the system. The last c ommand  p rovid es a p ic ture of the traffic  d ata g enerated  on 
eac h p roc essor interfac e link.

The p roc essor oc c up anc y c ommand s c an b e exec uted  from all user log ins if 
allowed  to. However, for most systems, the two p rimary users are the c ustomers’ 
telec ommunic ations manager and  the servic e tec hnic ian.
The typ e of ap p lic ation c an sig nific antly affec t p roc essor oc c upanc y. For 
p urp oses of d etermining  p roc essor oc c up anc y, the c ustomers’ c alling  traffic  is 
d efined  as one of the following  ap p lic ations:
nGeneral Business — The majority of ap p lic ations. It d oes not inc lud e the 
imp ac t of the Inb ound  Call Manag ement (ICM)/Call Manag ement System 
(CMS) or CallVisor Ad junc t Switc h Ap plic ations Interfac e (ASAI)/Outbound  
Call Manag ement (OCM) ap p lic ations.
nICM/CMS — Only inc lud es the imp ac t d ue to the ICM traffic  (using  the 
ACD, Call Vec toring , CallVisor ASAI, and  CMS features).
nCallVisor ASAI/OCM — Only inc lud es the impac t d ue to ASAI/OCM 
applications.
NOTE:
A p artic ular switc h may have a traffic  load  that c onsists of any 
c omb ination of the three defined  ap p lic ations.
Dep end ing  on the c ustomers’ sp ec ific  ap plic ation, the c alling  traffic  may b e as 
simp le as a sing le switc h with only CO trunks and  analog  sets or as c omp lex as a 
switc h in a multinod e p rivate network that uses b oth DCS and  ISDN features and  
is c onfig ured  with d ig ital sets. In ord er to d esc rib e this wide rang e of traffic , four 
c all c ategories are d efined  as follows:
nIntercom (INTCOM) — Loc ally mad e and  c omp leted  station-to-station 
calls.
nIncoming (INC) — Calls whic h c ome into the switc h over trunks from a 
CO. The following  trunk typ es are c onsid ered  p ub lic  network inc oming  
(CO, DID, FX, WATS, and  ISDN-PRI c alls with a p ub lic  network servic e 
type).
nOutgoing (OUT) — Calls which exit the switch on trunks that terminate in 
a CO. The following  trunk typ es are c onsid ered  p ub lic  network outg oing  
(CO, WATS, FX, and  ISDN-PRI c alls with a p ub lic  network servic e typ e).
nPrivate Network (PNET) — Inc oming  and  outg oing  c alls mad e over 
p rivate network trunks. The following  trunk typ es are c onsid ered  p rivate 
network (Ac c ess, CPE, DMI-BOS, RLT, Tand em, Tie, APLT, and  ISDN-PRI 
with a p rivate network servic e typ e).
A c ustomer’s Usag e Profile is d efined  as the p erc ent mix of traffic  from eac h of 
the four c all c ateg ories. An example of one Customer Usag e Profile would  b e: 
INTCOM =  34%, INC =  33%, OUT =  33%, and  PNET =  0%. Ob viously, many 
other different c ombinations are also possible.

Onc e the traffic  ap p lic ation, usag e profile, and  c ertain feature use load ing  fac tors 
are d etermined  it is then possible to c alc ulate the Busy Hour Call Cap ac ity 
(BHCC). The BHCC is a measure of the switc h’s c ap ac ity and  is defined  as the 
maximum numb er of c ompleted  c alls the switc h c an sup p ort in an hour without 
d eg rad ation of servic e.
It should  also b e und erstood that, as a p art of the RFP p roc ess, Luc ent 
Tec hnolog ies marketing , when g iven a d esc rip tion of the c ustomer’s usag e 
p rofile, traffic  ap p lic ation, and  c ertain feature use loading  fac tors for the 
p rop osed  switc h, c an c alc ulate the theoretic al maximum BHCC for the sp ec ified  
ap p lic ation. This enab les the d etermination of whether the p roposed  switc h c an 
ac c ommod ate the traffic  load . This numb er, the theoretic al maximum BHCC, is 
an estimate and  is referred  to as the p red ic ted  maximum BHCC.
The Summary Command
This sec tion d esc rib es the Summary Command  and  the Proc essor Oc c up anc y 
Su m m a r y  re p o r t .
When to Use the Summary Command
The main func tion of this c ommand  is to answer the q uestion, “ How muc h of the 
system is b eing  used ?”  More sp ec ific ally, this c ommand  should  b e used 
whenever you want to:
nMonitor resource usage
nValid ate the c ustomer’s usag e p rofile (for examp le, onc e the switc h is 
installed  and  c alling  traffic  is normal, use the summary rep orts to 
d etermine if the ac tual usag e p rofile is the same as the estimated usag e 
profile)
nDetermine the id le oc c up anc y and  how muc h is available for g rowing  the 
switc h
nDetermine the p roc essor oc c up anc y and  c all levels on an hourly b asis for 
the last 24 hours

Field Description
Meas Hour
Measurement Hour. The starting  time (using  24-hour c loc k) of 
the hour d uring  whic h the d ata is rec ord ed . Data is listed  
b eg inning  with the most rec ently c omp leted  hour in the 
p rec ed ing  24-hour interval. For add itional d etails, refer to the 
DEFINITY ECS System Desc rip tion and  Sp ec ific ations.
Meas 
Minute
Measured  Minute. (Last-Hour Rep ort) The end -time of the 
3-minute interval for whic h the measurement is taken. It takes 
the form hh:mm, where “ hh”  is the hour and  “ mm”  is the 
end -time for the 3-minute interval.
Date of 
Occurrence(Busiest-Interval Rep ort) The d ate and  end -time of the 
3-minute interval for whic h the d ata is c ollec ted . It takes the 
form MM/dd/mm:hh, where “MM” is the month, “dd” is the 
d ay, “ hh”  is the hour, and  “ mm”  is end  of the 3-minute 
interval.
Stat Occ
Static  Oc c up anc y. The amount of time (in CCS) taken b y hig h 
priority background processes in support of call processing, 
maintenanc e, and  ad ministration func tions. Examp les of this 
ac tivity are hig h level sanity c hec ks, system timing , p olling  of 
ad junc ts, and  op erating  system sup p ort. This also inc lud es 
some c all p roc essing  oc c up anc y for BX.25 and  ISDN-PRI 
traffic .
NOTE:
Static  Oc c up anc y remains fairly c onsistent in an id le 
switc h. However, it inc reases as traffic  is introd uc ed 
into the system.

CP OccCall Processing Oc cupancy. The amount of time (in CCS) 
taken b y c all p roc essing  level p roc esses. The p roc essing  of 
CDR, DCS, ISDN, and  other ad junc t interfac es is also 
inc lud ed in this level. Note that some oc c up anc y d ue to 
BX.25 and  ISDN-PRI c all traffic  is c ounted as static  
oc c up anc y instead of CP Oc c .
NOTE:
It is not d esirab le for any system to func tion at 100 
p erc ent Proc essor Oc c up anc y. Rather, the CP Oc c  and  
Stat Oc c  field s should total no more than a maximum of 
75 p erc ent. By maintaining  this 75 p erc ent maximum 
limit, other system func tions c an be p erformed  and  
b ursts of c aller ac tivity c an also b e ac c ommod ated .
Suggested Actions:
 If the 75 p erc ent maximum limit is 
exc eed ed, take one or more of the following  step s to lower 
Call Processing Occupancy:
Item #1
If the users d o not g et a d ial tone immed iately, they should  b e 
enc ourag ed  to wait 10 to 15 sec ond s b efore g oing  on-hook 
and off-hook again.
Item #2
If the switc h is part of a private network and is receiving a 
larg e amount of traffic  from another switc h in the p rivate 
network, investig ate the p ossib ility of rec onfig uring  the 
network.
Item #3
Chec k the ad ministration translation and  verify all d ig ital sets, 
ad ministered  with d isp lay mod ules, ac tually have d isp lay 
mod ules. For those sets without d isp lay mod ules, c hang e the 
ad ministration translations to ind ic ate the dig ital sets d o not 
have a d isp lay mod ule.
Item #4

.
Idle Occ
Idle Occ upancy. The amount of time the proc essor is unused . 
There are several fac tors that drive d own this numb er, 
inc lud ing : 
— a larg e offered  load , inc reases CP oc c up anc y
— a switc h with many stations and  trunks req uires a hig h 
level of b ac kg round  maintenanc e, inc reases SM 
oc c up anc y
— freq uent d emand  testing  or ad ministration, inc reases SM 
oc c up anc y
These fac tors may red uc e the id le oc c up anc y to almost 0% 
d uring  several 3-minute intervals. On a heavily-load ed switc h 
with freq uent d emand  testing , the id le oc c up anc y may d rop  
to low levels for long er p eriods (p erhap s 1–2 hours). These 
situations are normal and  d o not ind ic ate a p rob lem with the 
switch.
However, a lig htly-load ed  switc h with few stations translated  
and  little d emand maintenanc e or ad ministration should  not 
exp erienc e long  p eriod s of low id le oc c up anc y (less than 
15%). If this is the c ase, a p rob lem is likely. 
Total 
Calls
Total Calls. The total numb er of c alls c onnec ted  d uring  the 
listed hour. Calls are c ounted  in the time interval they are 
answered  and  not in the time interval they are d rop p ed . 
Therefore, a c all that starts in one time interval and  end s in 
another is c ounted only in the time interval where it orig inates.
Tandem 
Calls
Tand em Calls. The number of trunk-to-trunk c alls c onnec ted  
d uring  the last hour.

Using the Last-Hour Report to Resolve Problems
The following list id entifies some areas p ursued  when investig ating  a p rob lem 
b elieved  to b e p roc essor oc c up anc y (load ) related .
1. Multiply the numb er in the Total Calls field b y 20 for the id entified  3-minute 
time interval (the time when the p rob lem oc c urred ). If the p roduc t exc eed s 
the ad vertised  BHCC of the switc h, it is the load  for this time interval 
c ausing  the p roblem. If the p rod uc t does not exc eed  the BHCC for the 
switc h, this load  is not the p rob lem.
2. Compare the numb er in the Total Atmp ts field  with the Total Calls field  for 
the id entified  3-minute time interval (the time when the p roblem oc c urred ). 
If the numb er of attemp ts is sig nific antly g reater than the numb er of c alls, 
a sig nific ant p erc ent of the oc c up anc y is d ue to c all p roc essing stimuli 
that d o not result in c omp leted c alls.
3. Examine the hard ware error log  for an exc essive amount of maintenanc e 
activity (for example, a high number of errors).
