PRI Interfaces (3:3)
PRI Interface Configuration (3:3)
Allow NFAS
On: If set to On, the Allow NFAS is enabled.
Off: If set to Off, the Allow NFAS is disabled.
Non-Facilities Associated Signalling (NFAS), is an ISDN fea-
ture for sharing one ISDN D-channel across multiple ISDN PRI
interfaces.
•
The NFAS is only available on T1 networks
•
Backup D channels are not currently supported.
Example:
If we use NFAS to share one D channel across
eight PRI interfaces, we will gain seven extra B channels over
a configuration that used one D channel per PRI interface. Ad-
ditionally we may save expenses related to seven D channels.
INFO: The Initial Restart setting should be set to Off when
the Allow NFAS setting is enabled.
NFAS Group ID
It is possible to have 4 NFAS groups per card, where each
group may cover two or more PRI interfaces. Enter a value
between 1 and 4.
INFO:
This setting will only take effect when Allow NFAS is set
to On.
NFAS Interface ID
Each interface in an NFAS group must be assigned an NFAS
Interface ID.
•
These IDs must be the same as the ones used on the
network side of the interface.
•
Enter a value between 0 and 127.
•
The interface carrying the D channel for signalling must
be set to 0.
