NOTE:
This form only ap p lies to G3iV2 systems.
This form assigns proc essor c hannels to interfac e links. For ISDN-PRI, one 
p roc essor c hannel p er interfac e link is allowed. This ad ministration is used  b y the 
system software to id entify the link as an ISDN ap plic ation, rather than an X.25 
ap plic ation. The following  list d esc rib es the ad ministration setting s for the ISDN 
PRI-sp ec ific  field s in this administration form: Enab le You will not b e allowed  to enab le any links until all other field s in 
this form and all field s in the p roc essor c hannel assig nment

DS1/CEPT1 board  c orresp ond ing  to the link. The DS1/CEPT1 
board must have previously been administered as using ISDN 
sig naling  in the DS1 c irc uit p ac k form. This ad dress c an only

fac t that the trunks are d ig ital instead of analog  makes little d ifferenc e in the 
ad ministration. Also, all the g roup  typ es exc ept for ISDN PRI are some sp ec ific  
kind  of ap p lic ation. ISDN PRI g roup  types, on the other hand , are flexib le and  
c an func tion as any of these other g roup  types. Thus, it makes sense to d ivid e 
trunk g roup  ad ministration into ad ministration of b it-oriented  sig naling  trunk 
g roup s and  ISDN PRI trunk g roup s.
