Procedure 108 Word 1: ISDN Trunk 
Group TTL Number (Digits)
This p roc ed ure is used  to assign the terminating  test line numb er (used  in test 3 
of maintenanc e p roc ed ure 648) that id entifies the p artic ular B-c hannel used  for 
ISDN-PRI testing  p urp oses. This test line numb er must b e assigned  for both 
p rivate and  p ub lic  network c onfigurations. Whether more than one terminating  
test line number is need ed  d ep end s on the numb er of ISDN-PRI links and  
whether they terminate on more than one switc h.
Field 1
Translates the trunk g roup  that id entifies the ISDN terminating  test line. The 
terminating test line is req uired  for B-c hannel maintenanc e testing. As p art of the 
installation and ISDN-PRI servic es p rovisioning , the terminating  test line numb er 
assig nment must be c oord inated with the terminating  switc h.
Fields 2-17
Assig ns d ig its for the terminating  test line. If B-c hannel sig naling  c ontrol is used  
on the D-c hannel of another fac ility, you must use NFAS (see p roc edures 260, 
word  1; 262, word  1; 262, word  2; and  262, word  3).
Procedure 279 Word 1: Network Facilities Coding
Eac h interexc hang e c arrier (whic h p rovid es p ub lic  network ISDN servic e) must 
have a uniq ue id entifier numb er. Furthermore, eac h c arrier may p rovid e multip le 
ISDN servic es and  ISDN features that must be ind ivid ually id entified  via a 
Network Sp ec ific  Fac ility (NSF) c od ing value. A NSF is an ISDN IE (sent in the 
setup  message) that is used  to id entify the network or feature assoc iated  with the 
c all. When c onnec ted  to a 4ESS, a Generic  2 must send  the ap p rop riate NSF for 
MEGACOM, SDN, GSDN, and  ACCUNET switc hed  d ig ital servic e c alls. 
(MEGACOM 800 servic e c alls d o not req uire an NSF sinc e it is an inc oming -only 
servic e and the Generic  2 c annot tand em it to another switc h as a MEGACOM 
800 c all.)
All NSFs must b e d efined  in field  1 of this p roc ed ure p rior to use in p roc ed ure 
322 word  1.
Field 1
Translates Network Servic e. This field  is an arb itrary index number that you use 
to id entify the NSF d efined  in the rest of the field s.
.\ For MEGACOM, SDN, and  ACCUNET switc hed  d ig ital servic e c alls, assig n 
this same ind ex numb er in field  5 of p roc ed ure 309, word  5, and in field  4 of

Procedure 322 Word 1: WCR Outgoing ISDN
Feature Parameters
In this p roc ed ure you d efine an ISDN send ing ind ex and  then assign that ind ex to 
a p referenc e or a trunk g roup  in p roc ed ure 318 word  1. The following  list 
d esc rib es how to administer this p roc ed ure:
1. Disp lay the d esired ISDN send ing  ind ex in field 1. If this index has not yet 
b een ad ministered , it will have d efault values for all the field s.
2. In field  2, enter the network servic e value you want assoc iated with this 
ind ex. This servic e value must b e b uilt first in p roc ed ure 279. This value 
will b e used  to p op ulate the fac ility c od ing  p ortion of the NSF IE for c alls 
on trunk g roup s or p referenc es assig ned  to this ISDN send ing  index in 
p roc ed ure 318.
3. In field  3, enter the typ e of ad d ress you want to p op ulate the c alled  p arty 
number IE for calls on preferences or trunk groups assigned to this ISDN 
sending index. Following are the possible values:
0 - Unknown (d efault)
1 - International Number
2 - National Numb er
3 - Network Spec ific Number
4 - Sub sc rib er Numb er
6 - Abbreviated Number
7 - Reserved  for Extension
4. In field  4, enter the numb ering  p lan id entific ation you want to p op ulate the 
c alled  p arty numb er IE for c alls on trunk g roups or p referenc es assig ned  
to this ISDN send ing  ind ex. Following  are the p ossib le values:

Procedure 318 Word 1: ISDN Sending 
Index and Digit Sending Index
This p roc ed ure is used  to p op ulate several ISDN IEs on outg oing  c alls to 
p referenc es or trunk g roup s as follows:
nThe d ig it send ing  ind ex in field  8 d etermines whic h IE the IXC is sent in. 
An IXC is first d efined  in p roc ed ure 321, word  1, field s 7-11 for a g iven 
digit sending index. If field 7 is a 2
 or 3
, then the IXC assig ned  in field s 8 
throug h 11 will b e used  to p op ulate the network id entifier in the NSF. When 
this digit sending index is assigned to a trunk group or preference in field 
8, the assoc iated  IXC will be used  to p op ulate the outg oing  ISDN 
messag e. The IXC will p opulate one of three p ossib le IEs, d ep end ing on 
the setting  in proc ed ure 322, word  1, field  5 for the ISDN send ing  ind ex in 
field  9.
nThe ISDN send ing  index in field  9 d etermines how the c alled  p arty numb er 
and  NSF IEs are p opulated  for outg oing  c alls to this trunk g roup  or 
p referenc e. The send ing  ind ex is d efined  in p roc ed ure 322, word 1.
Procedure 318 Word 2: Assigns a 
BCCOS to a Preference
This p roc ed ure is used  to assign the b earer c ap ability c lass of servic e to a 
p referenc e. The BCCOS is d efined in proc ed ure 014.

AG2 ISDN PRI Implementation 
in Administration
This app end ix d esc ribes how ISDN PRI has b een imp lemented  in the 
ad ministration p roc edures in G2. It c overs the same sub jec ts found  in the ISDN 
PRI sections of Chap ter 5, ‘‘Layers 2 and  3’’
, but org anized  b y ad ministration 
p roc ed ure rather than b y ISDN PRI sub jec t.
Procedure 000 Word 3
Field  1 of this word assig ns the bearer c ap ab ility (BC) c lass of servic e (COS) 
numb er for the extension numb er. One imp lic ation of this COS is the pattern or 
p referenc e selec ted  for this extension on outg oing  c alls (see the ‘‘Proc ed ure 309 
Wo rd  5 ’’ sec tion later in this ap p end ix).
The 10 BCs are d efined  in field  16 of p roc ed ure 014, word  1. This definition 
c od es the BC information element (IE) in the setup  messag e when the extension 
(entered  in field  1 of p roc ed ure 000, word  3) ac c esses an ISDN-PRI trunk for an 
outg oing  c all.
The following  d efines the enc od ing  of the BC IE for the 10 p ossib le BCs.

 sec tion in this app end ix for more information).
Procedure 010 Word 4
This word  is used to assig n ISDN routing  p arameters to extensions. Field 3 
applies.
ISDN Routing Parameters
While many p arameters are assoc iated  with route selec tion (for examp le, Fac ility 
Restric tion Levels or FRLs, c omp atib le matc h of BCs, and  c lear c hannel versus 
restric ted  c hannel), the effec t of the ISDN routing  p arameter field  as it relates to 
route selec tion is disc ussed  next. There are three p ossib le enc od es that may b e 
entered in the applicable field:
Procedure 012
This p roc ed ure is used  to assign names to extension users or trunk group s. This 
d ata is used  in b uild ing the Disp lay IE used  in setup  and  c onnec t messag es. If 
d ata is not assig ned  for a c alling  p arty using  an ISDN-PRI trunk, a d isp lay IE is 
not c reated . The following  are some b asic  rules on the d isp lay IE:0
Use any availab le fac ility in a p attern. For examp le, based  on the sp ec ific  
d ialed  d ig its, you c ould  have a c all routed  to a sp ec ific  p attern that may 
have one or more p referenc es. The first availab le trunk found  in the 
hig hest p referenc e will b e used (for examp le, 1 is a hig her p referenc e 
than 2 and  2 is a hig her p referenc e than 3). Therefore, if an availab le 
trunk is found in preference 1, it is used.
1
Use an ISDN-PRI trunk exc lusively. When routed  to a sp ec ific  p attern, 
the first availab le ISDN trunk found  in the hig hest p referenc e is used . 
Non-ISDN trunk g roup  p referenc es are skip p ed  in the routing  alg orithm. 
If an ISDN-PRI trunk g roup  is not translated  in this p attern, the c alling  
p arty hears interc ep t tone.
This enc od e c an b e used  to ensure that an ISDN dig ital trunk is used  for 
a c ertain set of users (suc h as hig h-sp eed  d ata end p oints).
2
Use an ISDN trunk if one is availab le; otherwise use a fac ility of another 
typ e. The routing alg orithm selec ts the first availab le ISDN trunk of the 
hig hest p referenc e; otherwise it selec ts the first availab le non-ISDN trunk 
of the hig hest p referenc e assoc iated  with the p attern.
Using  this enc od e c an, when p ossib le, p rovid e user-to-user information 
for a p artic ular c all (suc h as transp orting  of c alling party name and  
numb er). When it is not p ossib le to p rovide this information, c all 
c omp letion c an still b e ac hieved  b y selec ting  a non-ISDN fac ility.
