back to the originating DPNSS1 side. The Step Back on Congestion
feature is then invoked, if it is configured.
•
If a congestion is encountered within the DPNSS1 portion of the path,
with the DPNSS1 trunk being used as a VNS Bearer, the VNS portion
of the call is cleared and a normal disconnection is propagated back to
the originating DPNSS1 side. The Step Back on Congestion feature is
not invoked, even if it is configured.
DPNSS1 Executive Intrusion
DPNSS1 Extension Three-Party Service is not supported over VNS Bearer
trunks. Attendant Break-in may be provided instead, if NAS is configured
over the VNS Bearer trunks.
Standalone Meridian Mail
Standalone Meridian Mail is not supported over VNS Bearer trunks.
A mailbox user may access Meridian Mail, if ISDN Network Message
Services is configured.
DPNSS1 Enhancements for ISDN Interworking
Software enhancements support DPNSS1 for ISDN interworking with
QSIG and EuroISDN. At an ISDN gateway, ISDN information may be
carried into some DPNSS1 messages, if DPNSS_189I package 284 is
equipped.
DPNSS1/DASS2 to ISDN PRI Gateway
A VNS call over a DPNSS1 or DASS2 Bearer trunk of an DPNSS1/DASS2
to ISDN PRI Gateway acts as the ISDN leg of the Gateway.
