Que AbdQueue Ab and oned. The numb er of c alls removed from the 
q ueue in one of the following  manners:
nBy the system b ec ause they have b een in the q ueue for 
more than 30 minutes
nBy the user (for examp le, d ialing  the c anc el c od e).
Suggested Action: 
Typ ic ally, this field ind ic ates a small 
number. However, a large number generally indicates the 
q ueue size is too larg e and  p eop le are ab and oning  b ec ause 
they remained  in q ueue for a long  hold ing  time and  g ave up .
Out Srv
Out of Servic e. The number of trunks in the trunk g roup  out of 
servic e (listed  as maintenanc e b usy) at the time d ata is 
c ollec ted . An ind ivid ual trunk may b e taken out of servic e b y 
the switc h whenever an exc essive numb er of errors oc c ur, or 
b y maintenanc e p ersonnel to run d iag nostic  tests.
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 
sp ec ific  d etails, refer to ‘‘Trunk Outage Measurements 
Report’’.

% 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 the trunks are b usy — either serving  calls 
or b ec ause they are b usied -out b y maintenanc e.
Suggested Actions:
1. If the group  d irec tion is outg oing  or two-way, then a hig h 
numb er in the % ATB field  and  nothing  in the Grp  Ovfl or 
Que 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 high number in the Grp Ovfl field. This indicates 
a possible p rob lem that nec essitates further analysis. 
Unless it is the last trunk g roup  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 , then a high numb er in 
this field  is b ad . It ind ic ates some inc oming  c alls are 
probably blocked. Generally, you want to add more trunks, 
thus lowering  the % ATB and  d ec reasing  the numb er of 
c alls b loc ked .

Perc entag e Outg oing  Bloc king is c alc ulated  as follows: 
Suggested Actions:
1. 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 
Que Ab d  field  to insure it stays within reasonable limits.
2. If c onditions are suc h that Step  1 is not ap p ropriate, then 
you may find  it nec essary to ad d more trunks.
NOTE:
If you are using  ARS you may see a high numb er in this 
field. This only ind ic ates c alls are overflowing  to the next 
choice.

Trunk Group Hourly Report
The Trunk Group  Hourly Rep ort p rovid es d ata nec essary to validate the 
information in the Trunk Group  Summary Rep ort and  to size the trunk g roup s. A 
sep arate rep ort is g enerated  for eac h trunk g roup . On the G3r, a maximum of 75 
trunk g roup s c an be stud ied  hourly at the same time. On the G3c si and  G3si, a 
maximum of 25 trunk group s c an b e studied .
NOTE:
In ord er to d isp lay these hourly rep orts, you must first c omp lete the Trunk 
Group  Measurement Selec tion sc reen. The Trunk Group  Measurement 
Selec tion sc reen is exp lained  immed iately after this sec tion ab out the Trunk 
Group Hourly Report.
Command
To d isp lay the Trunk Group  Hourly Rep ort:
1. Type list measurements trunk-group hourly  [print/schedule] 
and press 
RETURN.
Required Fields: There is one req uired  field  for this c ommand  —
assigned trunk group number
. Enter the trunk g roup  numb er for whic h 
you want to list trunk g roup  ac tivity.
Options: The print
 and  schedule
 op tions are availab le for this c ommand . Wideband 
FlagIf the trunk group supports wideband (n X DS0) switching, a 
“ W”  ap p ears next to the trunk g roup  entry. In ad d ition, if any 
trunk group on the report supports wideband switching, the 
tag “W = Wideband Support” appears in the report heading.
1. The usag e that wideb and  c alls c ontribute to this measurement is p roportional to the
resourc es the c alls c onsume. For examp le, a 384-kb p s c all c ontrib utes six times more
to the total usag e than d oes a 64-kb p s c all.
