7.3.2.2 Specifying the Scope and Mode
In AMI, the signalling scope (designated in AMI as
-sig_alloc
) and the signalling mode
(designated in AMI as
-sig_mode
) are now treated as a pair. The pertinent portion of the
AMI syntax is listed here for reference:
myswitch::configuration signalling> new <
port
> <
vpi
>
protocol options:
[-sig_alloc (vp | link | auto)]
[-sig_mode (nonAssoc | vpAssoc | auto)]
The scope and mode either both have to be
auto
or both have to be given a parameter other
than
auto
. Specifying the scope as
auto
and hard configuring the mode or vice-versa is not
allowed. If a scope is not entered, then the scope parameter defaults to
auto
. Similarly, the
mode parameter defaults to
auto
if a mode is not entered.
Table 7.5 shows the valid combinations.

This combination is valid as long as the
-type
is not con-
figured as
auto
or
privateNNI
. If the
-type
is
auto
, the
link could become a PNNI link, which would conflict with
a
-mode
of
nonAssoc
and a
-scope
of
vpScope
.
