Va l u e s :
A numb er from 1 to 17. Default is 1
.
Re f e re n c e :
Se c t io n  ‘‘Country-Sp ec ific  Layer 3 in G3V2’’ in Chap ter 5, 
‘‘Layers 2 and 3’’.
This field  will only b e d isp layed  if the Signaling Mode
 is 
isdn-pri
, isdn-ext
, or CAS
. This field  is used  for ISDN c alls and  
for non-ISDN c alls. For ISDN-PRI the field  is used  to spec ify the 
layer 3 PRI imp lementations ap p lic able for the selec ted  
c ountry. For non-ISDN it is used  to ind ic ate to the firmware what 
sig naling  p rotoc ol to use for CAS/CO c alls. Following  is the 
mapping of country protoc ol option to country:
Option   Country
1        United States
2        Australia
3        Japan
4        Italy
5        Netherlands
6        Singapore
7        Mexico
8        Belgium

13       Germany
14       Czechoslovakia
15       CIS (Russia)
16       Argentina
17       Greece
All entries are valid , thoug h only some make sense. For 
example, if the user c onfig ures this DS1/CEPT1 for CAS/CO 
op eration, only spec ific  c ountries are log ic al c hoic es for the 
c ountry p rotoc ol. This is d ue to the limitation of whic h c ountries 
spec ific  DS1/CEPT1 b oard s are c ap ab le of op erating in as 
CAS/CO c onfig urations. Thus, you c an enter any c ountry 
p rotoc ol. If the c ountry p rotoc ol value c hosen is not one whic h 
is rec og nized  for CAS/CO operation, the DS1/CEPT1 software 
will d ownlink the b est c hoic e for c ountry p rotoc ol for CAS/CO 
op eration. Eac h c ountry will b e map p ed  to a sp ec ific  c ountry 
for CAS/CO operation which best fits its operation. This 
map ping  is c hosen b ec ause it most c losely follows CCITT 
spec ific ations.

Connec tVa l u e s :

Re f e re n c e :
Se c t io n  ‘‘User-Network and  Peer Protoc ols’’ in Chapter 5, 
‘‘Layers 2 and 3’’.
Th e  Connect
 field  will only ap p ear if isdn-pri
 signaling is 
c hosen. This field  ind ic ates what is on the far end  of the PRI in 
ord er to c ontrol the layers 2 and  3 p rotoc ol p rop erly (see the 
following description of the Interface
 field ). The d efault value 
for this field  is network
. Network means that the trunks on this 
b oard  are c onnec ted  to a p ub lic  network switc h. Bec ause the 
p ub lic  network ISDN PRI p rotoc ol d iffers from c ountry to 
c ountry, a value of network here c auses the c ountry p rotoc ol 
field  to ap p ear in G3V2 systems, allowing  you to c hoose the 
c orrec t p rotoc ol. Similarly, if you ad minister host
, it means that 
the system is c onnec ted to a c omp uter of some kind . Ag ain, the 
c ountry p rotoc ol field  ap p ears in G3V2 systems. In G3V2 
systems in the U.S. (c ountry op tion 1) a value of network means 
the system is the user sid e in a user-network protoc ol and  a 
value of host means the system is the network sid e in a 
user-network p rotoc ol. If the Connect
 value is pbx
, it means 
the interfac e is c onnec ted  to another PBX, whic h d oes not 
nec essarily have any relationship  to the c ountry in whic h the 
system resides. Thus, instead  of the c ountry p rotoc ol field  
appearing, the field Interface
 ap p ears. In G3V2 systems, 
this field  allows you to c hoose a user-network p rotoc ol or a p eer 
p rotoc ol for PBX-to-PBX c onnec tions. If a p eer p rotoc ol is 
ad ministered , the c ountry p rotoc ol is not need ed bec ause a 
spec ific  p eer p rotoc ol (ECMA) has b een imp lemented . If a 
user-network p rotoc ol is c hosen, however, the c ountry p rotoc ol 
is relevant and  this field  will ap p ear in G3V2 systems.

InterfaceVa l u e s :
network
p eer-master (G3V2 only)
p eer-slave (G3V2 only)
user (d efault)
Re f e re n c e :
Se c t io n  ‘‘User-Network and  Peer Protoc ols’’ in Chapter 5, 
‘‘Layers 2 and 3’’.
This field  will only ap p ear if pbx
 is c hosen as the Connect
 
value. If you administer user
, the system is user at b oth layers 2 
and 3 in a user-network p rotoc ol for ISDN PRI c alls on trunks on 
this interfac e. If you ad minister network
, the system is network 
at layers 2 and  3 in a user-network p rotoc ol. If you ad minister 
peer-master
, the system is a master at layer 2 in the ECMA 
p eer p rotoc ol. If you ad minister peer-slave
, the system is a 
slave a layer 2 in the ECMA p eer p rotoc ol. When you ad minister 
user or network, the c ountry protoc ol field  app ears in G3V2 
systems. When you administer either peer-master or 
p eer-slave, two field s, peer protocol
 and side
, ap pear. 
The only c hoic e, and  thus the d efault, for the p eer p rotoc ol is 
the value ECMA
. Ad ministering  the system as side A means 
that the system is the A sid e at layer 3 in the ECMA p eer 
p rotoc ol. Similarly, ad ministering  the system as sid e B means 
that it is sid e B at layer 3 in the ECMA p eer p rotoc ol. For the 
p urp oses of hand ling glare, sid e A is roug hly eq uivalent to the 
network sid e at layer 3 and sid e B roug hly eq uivalent to the 
user sid e. Note that with the p eer p rotoc ol the layer 2 
ad ministration is not linked to the layer 3 administration.
NOTE:
When a G3V2 DS1/CEPT1 interfac e ad ministered  with a 
user-network p rotoc ol is c onnec ted  to a G2.2 interfac e, 
the G3V2 interfac e must b e ad ministered  as network and  
the G2.2 interfac e as user. This is b ec ause the 
user-network ad ministration on the G2.2 is only 
imp lemented  for layer 2. The layer 3 user/network 
relationship  in G2.2 is user b y default, whic h means the 
layer 3 user/network id entific ation must b e network in the 
G3V2, whic h in turn means the layer 2 user/network is 
also network, whic h in turn means the layer 2 
user/network on the G2.2 must be user. If a G3V2 
ad ministered  for the ECMA p eer p rotoc ol is c onnec ted  to 
a G2.2, you must make sure that if the G2.2 is 
ad ministered  as user at layer 2 then the G3V2 is 
ad ministered  as p eer-master and c onversely, as p eer 
slave if the G2.2 is network. The following  tab le shows the 
rec ommend ed  ways to ad minister the user-network and  
peer p rotoc ols when a G2.2 is c onnec ted  to a G3V2:
