Traffic Summary Report
The Traffic  Summary Rep ort p rovid es an overview of system p erformanc e. 
Summarized  in the rep ort are p eak hour c all p roc essing  and  system 
manag ement oc c up anc y, p eak hour b loc king for TDM time slots on eac h p ort 
network, p eak hour b loc king  for p ort network links and  switc h node links, and  the 
p eak hour for the TDM time slots, p ort network links and  switc h nod e links 
c omb ined , p eak hour for the worst attend ant sp eed  of servic e, and  the p eak for 
tod ay and  yesterd ay for trunk b locking  for the worst five trunk g roups.
Also inc lud ed  are a series of traffic  flag s and  c ounters p rovided  for the last hour 
of measurement d ata. They inc lud e a time stamp  for a major alarm, trunk g roup , 
wideband trunk group, coverage path, coverage principals, and routing-pattern 
time stamp s for measurement selec tion mod ific ations.
There are, as well, for last hour, totals for Trunks Out of Servic e, CDR hig h water 
mark and  overflow, and total sec urity violations.
NOTE:
Data in this report is not up d ated  on d emand . It is g enerated  every hour on 
the hour and  c an be used  to id entify p rob lem areas in the system. More 
d etailed  d ata c an b e retrieved from other measurements rep orts, as noted 
in the field descriptions.
When a p otential p rob lem is id entified  from this rep ort, other more d etailed  
rep orts in the susp ec t area are req uired  to ad eq uately c harac terize the prob lem.

time slot seizure failures d ue to insuffic ient time slots for any 
PN. This is time c oinc id ent with Peak Total Bloc king  ab ove. It 
is c omp uted  as follows:
Hig hest PN Blk =  (TDM Bloc kag e x 100) / TDM Pegs
High 
PNL/SNL 
BlkHighest Port Network Link/Switch Node Link Blocking. (G3r 
only). The hig hest p erc ent of SNL and PNL seizure failures

meaningful for links b etween Center Stag e Nodes or T1 
remote PNs sinc e c onnec tivity to the Center Stag e from any

Field Description
Peak Hour 
for All 
Trunk 
GroupsThe hour d uring  the sp ec ified  d ay with the larg est total usag e, 
when summed  over all trunk g roup s. Peak hour and  busy hour 
are synonymous. With c onventional traffic  theory d ata 
analysis, there are two method s for d etermining  the p eak hour. 
One is the time-c oinc ident p eak hour, meaning  that 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  that the 
hig hest usag e is selec ted  for eac h d ay without reg ard  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 oinc id ent 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, 
then the peak 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 Siz
Group Size. The numb er of ad ministered  trunks in the trunk

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

 rep ort, the measurement 
hour is the peak hour for eac h trunk g roup  yesterd ay (eac h

Total 
Usage1Total usag e (in CCS) for all trunks in the trunk group . 
Rep resents the total time the trunks are b usy (with c alls) 
d uring  the one-hour measurement p eriod . Total usag e 
measures eac h time a trunk is seized  for use b y an inc oming 
c all (whether it is p ic ked  up  or not) or an out g oing  c all (only 
after d ig its have b een d ialed ).
Total 
SeizeThe numb er of inc oming  and  outg oing  seizures c arried on the 
trunk g roup . This inc lud es the numb er of times a trunk in the 
g roup  is seized , inc lud ing  false starts, d on’t answer, and  busy.
Inc. Seize
Incoming Seize. The numb er of inc oming  seizures c arried  on 
the trunk group.
Grp Ovf
Group Overflow. The numb er of c alls offered to a trunk g roup  
not c arried  or q ueued  (if a q ueue is p resent). Calls rejec ted for 
authorization reasons are not inc lud ed .
Que Siz
Trunk Group  Queue Size. A number (0 to 100) that id entifies 
the numb er of slots assigned  to the trunk g roup  q ueue. This 
numb er represents how many c alls may b e held  in q ueue b y 
the trunk g roup . If 0 is d isp layed , then no q ueue is 
ad ministered . Henc e, the other q ueue measurements are also 
0. Generally, the q ueue size should  b e larg er than the trunk 
g roup  size; however, not more than three times as larg e as the 
trunk g roup  size.
Call Qued
Calls Queued. The total number of c alls that entered  the trunk 
g roup  q ueue after find ing all trunks b usy.
Que Ovf
Queue Overflow. The total numb er of c alls not q ueued  
b ec ause the q ueue is full. These c alls rec eive a reord er sig nal.
Suggested Actions:
 Generally, this field indic ates the number 
0. If this field  indic ates a hig h numb er, then either the q ueue 
size may b e too small, or ad d more trunks to red uc e the 
numb er of c alls queuing .
