Ovf TGOverflow Trunk Group. The numb er of outg oing  c alls that 
req uested  the sp ec ified  servic e/feature, on the ISDN-PRI 
CBC trunk group, but are not carried because the calls 
arrived  to find  no id le trunk members availab le.
NOTE:
There are three overflow field s, eac h with a d ifferent 
p riority. They are: overflow trunk g roup (Ovf TG
) 
(priority 1), overflow maximum (Ovf Max
) (p riority 2), 
and  overflow servic es/features (Ovf S/F
) (p riority 3). If 
more than one of the overflow c ond itions is met, only 
the field  that rep resents the c ond ition with the hig hest 
p riority is inc remented .
Ovf S/F
Overflow Servic es/Features. The numb er of c alls that 
req uested  the sp ec ified  servic e/feature b ut d enied  b ec ause 
the c alls arrived  und er the following  c ond itions:
nThe spec ified  servic e/feature is at or ab ove its minimum 
c hannel alloc ation and b elow its maximum alloc ation.
nThere are id le c hannels availab le in the trunk group , b ut 
they are reserved  to meet the minimum c hannel alloc ation 
for other servic es/features.
Suggested Actions:
1.Investigate the p ossib ility of raising  the “ Min Chn”  
req uirements for this servic e/feature.
2. Investigate the p ossib ility of inc reasing the number of 
memb ers for the trunk g roup .
3. Determine whether or not the “ Min Chn”  assig nments for 
the other services/features are appropriate. For example, 
if the c olumn “ % TBM”  d isp lays a hig h numb er for one or 
more of the other servic e/features, then you c an lower the 
minimums (for one or more of the other servic es/features). 
This makes more trunks availab le for this servic e/feature.

Ovf MaxOverflow maximum. The numb er of c alls not c arried b ec ause 
the c alls orig inated  at a time when the servic e/feature alread y 
used -up  its allotted  maximum numb er of c hannels. In this 
c ase, the trunk g roup  may still have trunk memb ers available 
for the other servic es/features.
Suggested Actions:
1. Investigate the p ossib ility of raising  the numb er 
ad ministered  in the Max Chn field . This is only p ossib le 
p rovid ed the free p ool is not exc eed ed . To d etermine 
whether or not you have more trunks availab le for a S/F 
calculate the following: 
For example, use the above equations with the data in the 
formula as follows: 
2. Consid er ad d ing  more trunks to the trunk g roup  and  
inc rease the maximum for the id entified  servic e/feature.
% TBM
Percentage of Trunks Below Minimum. The p erc entag e of 
time d uring  the p olling  interval that the numb er of c hannels in 
use by the sp ec ified  servic e/feature is b elow the sp ec ified  
minimum.
Suggested Action:
 Lower the “ Min Chn”  sinc e this may b e 
the c ause for the “ Ovf S/F” .
NOTE:
If the % TBM field  is hig h, then you are reserving  more 
trunk memb ers than will b e used. Determine if another 
servic e/feature need s more trunks and , if so, lower the 
“ Min Chn”  for this servic e/feature.

% ATBPercentag e All Trunks Busy (ATB). The p erc entag e of time (0 
to 100%) d uring  the measurement interval that the sp ec ified  
servic e/feature c ould not get a c hannel b ec ause of at least 
one of the following  reasons:
nAll trunks in the ISDN-PRI CBC trunk g roup  are b usy on a 
c all or b usied -out b y maintenanc e.
nThis servic e/feature is ab ove its minimum; and  all 
availab le trunks are reserved  for other features/servic es 
b elow their minimums.
nThe sp ec ified  feature or servic e is at its maximum numb er 
of c hannels.
Suggested Actions:
1. A number in the Ovf TG field  ind ic ates the p hysic al 
maximum numb er of trunks is exhausted . Unless the 
trunk g roup  is the last p referenc e in the routing  p attern, 
overflow is to the next trunk g roup . Otherwise, the 
ob vious c hoic e is to ad d  more trunks to the trunk g roup .
2. If the Ovf S/F field  ind ic ates a p rob lem (for examp le, a 
sig nific ant number), refer to Suggested Actions
 in the 
Ovf S/F description.
3. If the Ovf Max field  ind ic ates a p rob lem (for examp le, a 
sig nific ant number), refer to Suggested Actions
 in the 
Ovf Max d escrip tion.
NOTE:
If the ISDN-PRI CBC trunk g roup  is ad ministered  to

% BLKPerc entag e Outg oing  Bloc king. The ratio of outg oing  c alls 
not c arried  for a sp ec ified  servic e/feature to the outg oing  
c alls offered by the servic e/feature. For an ISDN-PRI CBC 
trunk g roup  without a q ueue, the c alls not c arried  are those 
c alls that find all fac ilities b usy for the sp ec ified 
servic e/feature. For an ISDN-PRI CBC trunk g roup  with a

c alls that find all fac ilities for the sp ec ified  servic e/feature 
b usy and  c annot b e q ueued  b ec ause the q ueue is full.
Suggested Actions:
1. Look at the % ATB c olumn and  id entify any 
servic e/feature with a hig h value. Follow the Suggested 
Actions
 in the % ATB d esc rip tion.
2. You c an inc rease the leng th of the q ueue rather than 
ad d ing  more trunks. Sub seq uently, you should monitor 
the Queue Ab and onments field  to insure it stays within 
reasonab le limits.
3. If c ond itions are suc h that Item 1 ab ove is not 
ap p rop riate, you may find it nec essary to ad d  more 
trunks.

Peak Hour 
for 
Wideband 
Usage for 
All Trunk 
GroupsThe hour d uring  the sp ec ified  d ay with the hig hest total 
wid eb and  c all usag e, when summed  over all trunk group s. 
Peak hour and  b usy hour are synonymous. With c onventional 
traffic  theory data analysis, there are two method s for 
d etermining  the p eak hour. One is the time-c onsistent p eak 
hour, meaning  hourly usag e values are averag ed  ac ross d ays 
for eac h hour of the d ay. The other is the b ounc ing  p eak hour, 
meaning the hig hest usag e is selec ted  for eac h d ay without 
regard  to the averag e ac ross d ays. For the b ounc ing  p eak 
hour, the hig hest load  on a g iven d ay may or may not oc c ur 
d uring  the time-c onsistent busy hour. These traffic  rep orts and  
ac c omp anying  trunk g roup  d ata worksheet only use the 
b ounc ing  p eak hour method . Note that if the total usag e for the 
c urrent hour eq uals the total usag e for the p revious p eak hour, 
the p eak hour is the hour with the g reatest numb er of total 
seizures.
Grp No.
Group Numb er. A numb er that id entifies eac h trunk g roup  
assoc iated  with the d isp layed  d ata. Group  numb ers are 
d isp layed  in numeric al ord er, b eg inning  with the lowest 
ad ministered  number and  c ontinuing  to the hig hest 
ad ministered  number.
Grp Size
Group Size. The numb er of ad ministered  trunks in the trunk 
group.
Grp Dir
Trunk Group  Direc tion. Id entifies whether the trunk g roup is 
inc oming  (inc
), outgoing (out
), or two-way (two

Service 
Type
Se rv i c e  Typ e. The ad ministered  Servic e Typ e for the trunk

mega800, megacom, multiquest, operator, other, 
outwats-bnd, public-ntwrk, sdn, sub-operator, 
and wats-max-bnd.
Meas Hour
Measurement Hour. The hour (using  24-hour c loc k) in whic h 
the measurements are taken. For the last-hour
 rep ort, it is the 
last hour of measurement (eac h trunk g roup ’s measurement 
hour is identic al; b ut not nec essarily the same as the ind ic ated  
p eak hour for the d ay). For the today-peak
 rep ort, the 
measurement hour is the p eak hour for eac h trunk g roup  thus 
far tod ay (eac h trunk g roup ’s measurement hour c ould  b e 
d ifferent). For the yesterday-peak
 rep ort, the measurement 
hour is the peak hour for eac h trunk g roup  yesterd ay (eac h 
trunk g roup ’s measurement hour c ould  b e d ifferent).

Out Serv
Out of Servic e. The number of trunks in the trunk g roup  out of

Suggested Action:
 If the trunks are removed  from servic e b y 
the switc h, then the ap p rop riate maintenanc e p ersonnel 
should be notified . The ob jec tive is to keep  all memb ers of a 
trunk g roup  “ in servic e.”  Generally, you should  not make 
ad justments to the trunk g roup  b ec ause of “ Out of Servic e”  
trunks, but should  g et those trunks returned  to servic e. For
