nParameterized  field
The following  field s of the NSF follow the same rules as g iven for System 85 R2V4 
NSFs:
nNetwork id entific ation p lan
nTyp e of network identific ation
nNetwork id entific ation
Rules for req uesting  ACCUNET servic es from d ifferent g eneric s of 4ESS are the 
same as those for System 85 R2V4. That is, when d ealing with 4E13 or later, set 
up  a d efinition of a b inary servic e with a value of 6
. This definition is used  in field  
6 of p roc ed ure 309, word  5, that send s an NSF (this is the p arallel to the ab ove 
examp le for System 85 R2V4 where a value of 357
 was used).
For g eneric s b efore 4E13, NSF is not sent; instead , the setup  messag e need s a 
mod e 1 c od e. For Generic  2, there is no sp ec ial enc od e that c auses messag e 
c reation to do this automatic ally. Therefore, the c alling  p arty wishing  to ac c ess 
ACCUNET from g eneric s b efore 4E13 must have a BCCOS of mod e 1.
BC
BC is assig ned  with field  6 for Generic  2. This field has imp lic ations as far as c all 
routing  is c onc erned . Some routing  rules are d isc ussed  in the ‘‘Proc ed ure 010 
Wo rd  4 ’’ sec tion of this ap p end ix. Ad d itional routing  rules b ased  on the b earer 
c ap ab ility translation assoc iated  with a p lan, p attern, or p referenc e are 
described next.
Field  6 (Generic  2)
Field  16 of p roc ed ure 014, word  1, d efines the BC for the c alling  p artys COS. 
Field s 4 throug h 13 of p roc ed ure 014, word  1, d efine the b earer c ap ab ility COS 
of the p referenc e. Field  6 of p roc ed ure 309, word  5, d efines how to handle 
c alling  p arties. If a c alling  party with a p artic ular BC is to b e b loc ked  from using  
this p referenc e, the next p referenc e is c hec ked . If all p referenc es bloc k this 
p artic ular BC, the c all is d enied .
In ad d ition, Generic  2 also imp lements the following  routing  rules:
nWhen searc hing  the p referenc es, the hig hest p referenc e numb er is used  
that c an hand le the c all via c irc uit switc hing  instead  of using a mod em 
p ool member (where the numb er \E3 1\E1 is the hig hest p ossib le 
p referenc e). This is d one to c onserve the use of mod em p ool memb ers. 
(Of c ourse, all other routing  rules d isc ussed  in this ap p end ix must also b e 
met for this p referenc e.) If a c irc uit switc hed  p referenc e c annot b e found, 
the highest non-c irc uit switc hed  p referenc e is used . Field s 4 throug h 13 of 
p roc ed ure 014, word  1, d efine c irc uit versus non-c irc uit switc hing  for the 
BCCOS entered  in field  6 of p roc ed ure 309, word  5.

nA c alling  party with c lear c hannel c harac teristic s is b loc ked from using  a 
p referenc e with restric ted  c hannel c harac teristic s.
.IX Restric ted c hannel
All other c alling  p arty and  preferenc e c lear or restric ted  c omb inations are 
allowed.
The c alling  p artys c lear or restric ted  c harac teristic  of the c alling  p artys BCCOS 
is d efined  in field 15 of p roc ed ure 014, word  1.
The p referenc es c harac teristic  is found  b y examining  field  3 for the BCCOS 
entered  in field  6 of proc ed ure 309, word  5.
Procedure 321 Word 5
This word  d efines for AAR p atterns and  p referenc es what proc edure 309, word  
5, d efines for ARS p lans, p atterns, and  p referenc es. The fields in these two 
p roc ed ures are similar. Refer to the ‘‘Proc ed ure 309 Word  5’’
 sec tion earlier in this 
ap pend ix for information on how to ad minister this p roc ed ure (all rules and field  
d efinitions are identic al).
Procedure 354 Word 3
This word is used to assign up to 99 unique NPA-NXX pairs. For example, a 
loc ation c an have two d istinc t d esig nators: one for voic e extensions (suc h as 
303-538) and  one for d ata end p oints (suc h as 303-255).
Generic  2 sends out 10 ad d ress d ig its for c alling  party numb er and c onnec ted  
numb er. The NPA-NXX p ortion of the numb er is d efined  in this word via field s 2 
and  3. These 6 d igits are p rep end ed  to the last 4 d ig its of the extension numb er 
to c reate the 10 ad d ress dig its. (If a c onsole is involved , the last 4 d ig its of the 
assig ned  listed  d irec tory numb er (LDN) are used .)
In addition, a thousands digit can be assigned in field 4. This digit must be 
assig ned  in 3-d ig it switc hes for the c alling  p arty numb er and  c onnec ted  numb er 
to make sense. If assig ned  in a 4 or 5-dig it switc h, it is used  for the thousand s 
d ig it in the ad dress d ig it stream reg ard less of what the thousand s d ig it is for the 
extension or LDN.

Procedure 420
Type-2 data can be useful in determining which regular tasks are using an 
ab normally hig h amount of proc essor time. The d ata in field  3 of this p roc ed ure 
multip lied  b y 100 is the numb er of times this task has b een interrup ted  b y the 
10-ms interrup t. An unusually hig h numb er in field  3 (c omp ared  to the other 
reg ular tasks) shows that the task numb er in field  2 is c urrently a 
p roc essor-oc c up anc y hog . This c ond ition is normally an error c ond ition and  c an 
p oint to p rob lems with the feature c ontrolled  b y the reg ular task. The following 
are ISDN-related  tasks and  their task numbers for Generic  2:
Task 35 ISDN queue server task
Task 47 ISDN level-3 timing  task
Task 55 ISDN JUMBO I/O task
Task 61 ISDN inc oming  messag e-verific ation task

BDigital Trunk Administration
Summary for U.S. Applications
The tab les in this ap p end ix serve as a q uic k referenc e to some of the trunk g roup  
ad ministration setting s for DS1-b ased  trunks in the U.S. g iven the ap p lic ations for 
the trunks.
nThe tables are organized by the bearer capability class (BCC) of the 
information they transp ort, as follows:
— Dig ital trunks c an c arry voic e or voic e-g rad e d ata.
— Dig ital trunks c an c arry 64 kb p s d ata p er c hannel. Dig ital 
multip lexed  interfac e (DMI) mod es 0, 2, and  3 all use 64 kb p s 
c hannels.
— Dig ital trunks c an c arry 56 kb p s d ata p er c hannel, also c alled  DMI 
mode 1.
nEac h tab le is d ivid ed  into several c ateg ories, as follows:
—
Trunk app lic ation id entifies the type of eq uip ment to whic h the 
DEFINITY system is c onnec ted  via the trunk, suc h as a loc al 
exc hange switc h, a toll switc h, another PBX, or to some other 
sp ec ialized  eq uip ment.
—
Se rv ic e is the purpose for which the trunk is used.
—
Connec tivity is the sp ec ific  eq uip ment to whic h the far end  of the 
trunk is c onnec ted .
—
Ad ministration op tions are the key items that must b e ad ministered 
for the trunks on the DEFINITY systems. These are the 
rec ommend ed  ad ministration setting s and  often the only c orrec t 
ones.
—
Interfac e c irc uit is the circ uit pack on the DEFINITY system to which 
the trunk c onnec ts.
