% ATBPerc entag e All Trunks Busy. The p erc entage of time all trunks 
in the trunk g roup  were simultaneously in use d uring  the 
measurement interval.
NOTE:
In use means that the trunks are b usy — either serving  
c alls or b ec ause they are busied -out b y maintenanc e.
Suggested Actions:
1. If the group  d irec tion is outg oing  or two-way, a hig h 
numb er in the % ATB field  and  nothing  in the Grp  Ovfl 
ind ic ates everything  is func tioning  normally. However, a 
more typ ic al sc enario is a hig h numb er in this field  and  a 
hig h numb er in the Grp  Ovfl field . This indic ates a p ossib le 
p roblem that nec essitates further analysis. Unless this 
trunk g roup  is the last p referenc e in the p attern, overflow is 
to the next c hoic e trunk g roup, and  the numb er in the Grp  
Ovfl field  is of no great sig nific anc e. Otherwise, the 
ob vious c hoic e is to ad d  more trunks to the trunk g roup .
2. If the group  d irec tion is inc oming , a hig h numb er in this 
field is b ad . It indic ates some inc oming  c alls are p rob ab ly 
b loc ked . Generally, you want to ad d  more trunks, thus 
lowering  the % ATB and  d ec reasing  the numb er of c alls 
blocked.

rep orted  for the hourly rep ort. (Measurements on ad ministered  trunk g roups are 
c ollec ted  to list them on the wid eb and  summary and  hourly rep orts.) A maximum 
of 10 trunks c an b e stud ied  on the G3c si and  G3si. On the G3r, the maximum is 
30. If no selec tions are mad e, no trunk g roup s are stud ied  hourly.

Data Analysis Guidelines
The wid eb and  summary and  hourly rep orts c losely p arallel the other trunk g roup 
summary and  hourly rep orts. That is, visually they c ontain similar field s, exc ep t 
there is no q ueuing  for wid eb and  c alls, so q ueuing  field s are eliminated . 
Log ic ally, the differenc e is that only the wideb and  rep orts isolate wid eb and  c all 
usag e. If the trunk g roup  p roc esses ord inary narrowb and  c alls d uring  the 
measurement period , the narrowb and  measurements are 
not inc lud ed in the 
wid eband  traffic  measurements.
With the overall trunk g roup  measurements and  the wid eb and  trunk g roup  
measurements, you have data for all usag e and  c an c alc ulate the narrowb and  
c all usag e and  c ounts b y sub trac ting  the wideb and  measurement from the 
overall measurements.

Wideband Trunk Group Summary Report
The Wid eband  Trunk Group Summary Rep ort provid es d ata essential for 
monitoring  trunk g roups sup p orting wid eb and  servic e to assure they p rovid e the 
exp ec ted  level of servic e. The rep ort is mod eled  after the Trunk Group  Summary 
Rep ort b ut only trunk g roup s ad ministered  to p rovid e wid eb and  servic e are 
rep orted . Other trunk g roup s d o not ap p ear on the rep ort. If a trunk g roup  is 
ad ministered  to p rovid e wid eb and  servic e b ut had no wid eb and  traffic  d uring  the 
measurement period , then zeros are shown on the rep ort.
The yesterd ay-p eak and  tod ay-p eak rep orts list the wid eb and  c all ac tivity for the 
p eak wid eb and  traffic  hour. That is, the measurements shown are those that 
oc c urred  d uring  the hour in whic h the Total Usag e for wid eband  servic e for that 
trunk group  was hig hest. This is not nec essarily the same p eak hour as the p eak 
hour for total usag e as shown on the overall Trunk Group  Summary Rep ort. Note 
that on the Wid eb and  Trunk Group  Summary Report, the measurements for 
d ifferent trunk g roup s are not nec essarily time-c oinc id ent with eac h other.
!CAUTION:
The yesterd ay-p eak and  tod ay-p eak rep orts c annot b e used  to d etermine 
narrowb and  usag e exc ept in c ases where the p eak traffic  hour for total 
usag e (shown on the overall rep ort) is the same as the p eak hour for 
wid eband  usag e (shown on this rep ort) for a p artic ular trunk g roup  in the 
same measurement p eriod . In this c ase alone, narrowband  measurements 
for that trunk group  may b e d etermined by sub trac ting the wid eb and  
measurements from the measurements shown on the overall rep ort for the 
same trunk group.
!CAUTION:
For trunk group s where the p eak hour is d ifferent on the overall summary 
rep ort from that shown on the wideb and  summary rep ort, the narrowb and  
usag e must b e d etermined  b y using  the measurements on the Wid eb and  
Trunk Group  Hourly Rep ort. In ad d ition, if there were c alls b loc ked  at that 
time, the group should be studied using both the overall and wideband 
hourly reports to determine whether wideband calls were blocked.

Wideband Trunk Group Hourly Report
The Wid eband  Trunk Group Hourly Rep ort shows the wid eb and c all ac tivity for 
eac h hour in the c urrent 24-hour p eriod . A separate rep ort is g enerated  for eac h 
measured wideband trunk group.
For trunk group s having  mixed  wid eb and  and  narrowb and traffic , it is b est to 
ad minister the trunk g roup  to app ear on b oth the overall and  wid eb and  hourly 
trunk g roup  rep orts. In this way a c omp lete p ic ture of usag e and  b loc kag es is 
p ossib le. For these trunk g roup s, d irec t c omparisons c an b e mad e between 
measurements for the same hour on the overall and  wideb and  rep orts. For 
examp le, if the hour b eg inning  at 1:00 p.m. is examined  for the same trunk g roup  
on both the overall hourly rep ort and on the wid eb and  hourly rep ort, the 
narrowb and  usag e measurements may b e d etermined  b y sub trac ting  the 
wid eband  d ata from the overall data. This c an be d one for eac h hour in the 
24-hour p eriod .
Note that some measurements, suc h as trunks-out-servic e and  all-trunks-b usy, 
are id entic al for the same hour on b oth the wid eb and  and  the overall rep orts for 
the same trunk group.
Performance Considerations
Althoug h the DEFINITY ECS sup p orts wid eb and  transmission for from 2 to 30 
c hannels, the most c ommon transmissions are at the H c hannel rates:
When c onsid ering  how many trunks to p ut in a trunk g roup  that sup p orts 
wid eband  c all ac tivity, rememb er:
nEvery wid eb and  c all must b e c arried  on a sing le DS1 interfac e. That is, 
when the b and wid th on one interfac e is insuffic ient for the c all, another 
interfac e must b e found that c an ac c ommod ate the entire c all. The 
b and wid th for the c all 
c annot b e sp read  over 2 or more interfac es. The 
c hanc es for find ing  enoug h b andwid th on a sing le interfac e are far less 
than find ing  the b and wid th on several interfac es.

sing le interfac e, b ut the c hannels over whic h the c all is c arried  must b e 
c onsec utively numb ered . The c hanc es for find ing  c ontig uous b and wid th 
are far less than for find ing  the band wid th on a sing le interfac e alone. H Rate Speed # 64-Kbps Channels
