Field 2
The ISDN-PRI d oes not p lac e any new or add itional c onsid erations on translating  
these field s. The enc od es that are translated  are g enerally d ep end ent on eac h

Field 3
Determines the numb er of traveling  c lass marks (TCMs) a trunk g roup  will send  
and receive. Encodes are:
Field 4
Used  to selec t (1
) or d isallow (0
) symmetric al routing .
Proc ed ure 285 field  5 is used  to ad minister the symmetric al routing  d ep th. If a 
c all enters the switc h on a trunk whic h has the network/tand em field s in 
p roc ed ure 103, word  1, set to 1,1 and  the symmetric al routing  d ep th field is set to 
a non-zero value, then the trunk g roup  is p art of a symmetric al route. After a 
p attern is selec ted , p referenc es for whic h the outg oing  trunk g roup  has the 
network/tand em field s in Proc ed ure 103 set to 1,1 and  for whic h the p referenc e 
numb er is g reater than the symmetric al routing  d ep th are ig nored .
If a c all enters the switc h on a trunk g roup that is p art of a symmetric al route (that 
is, p roc ed ure 103, word  1, field  4 is set to 1) and  the symmetric al routing  d ep th 
field  for the switc h is set to a non-zero value, then symmetric al routing  oc c urs. 
After a p attern is selec ted , p referenc es for whic h the outg oing  trunk g roup  has

Fields 5-8
The ISDN-PRI d oes not p lac e any new or add itional c onsid erations on translating

p roc ed ure 318, word  1) and  Dial Tone Detec t Ignore field  for the trunk g roup 
(procedure 103, word 1, field 9) determine when digit sending begins. An

first digit sending group. If the first pause is 0, digit sending begins immediately.
If Dial Tone is d etec ted  while p ausing  b efore send ing the first g roup and  Dial

This field  affec ts how Network Digit Collec tion op erates and  when route selec tion 
is attempted  for network c alls arriving  on a trunk g roup . The d ifferenc es b etween

When a c all that arrives on a trunk g roup  for whic h this field  is zero enters
