Feature Interactions - Nortel Communication Server 1000 Manual

68 Virtual Network Services in the UK with DASS2/DPNSS1 Bearers
No DPNSS1 features are provided when DPNSS1 trunks are used as
a VNS Bearer trunk. ISDN features are provided instead. If any of the
DPNSS1 Supplementary Service features requires a DPNSS1 route, it
cannot use a VNS route.
If ESN is configured, a route list entry with both VNS and DPNSS1 is not
chosen.
For DPNSS1/VNS gateway nodes in mixed DASS2/DPNSS1 and VNS
networks, the gateway nodes are subject to the same feature support
and limitations as the standard DPNSS1/ISDN gateway without VNS. If
there is no DPNSS1/ISDN gateway, the feature will be stopped at the
DPNSS1/VNS node.

Feature interactions

Analog Private Networking Signaling System
Analog Private Networking Signaling System (APNSS) trunks cannot
function as VNS Bearer trunks.
Data calls
Data calls are supported on DPNSS1 or DASS2 VNS Bearer trunks if the
DPNSS1 or DASS2 VNS Bearer trunks are configured to support data
calls. Similarly, data calls are supported on DPNSS1 or DASS2 Bearer
trunks in VNS to DPNSS1/DASS2 gateways, if the DPNSS1 or DASS2
VNS Bearer trunks are configured to support data calls.
DPNSS1 Attendant Call Offer
DPNSS1 Attendant Call Offer is not supported over VNS Bearer trunks
(DPNSS1 Attendant Call Offer allows an attendant-extended call, routed
over a DPNSS1 trunk, to be camped-on to a remote busy extension).
Standard ISDN Camp-on may be provided instead, if NAS is configured
over the VNS Bearer trunks.
DPNSS1 Attendant Timed Reminder Recall and Attendant
Three-Party Service
DPNSS1 Attendant Timed Reminder Recall and Attendant Three-Party
Service are not supported over VNS Bearer trunks. If NAS is configured
over the VNS Bearer trunks, NAS call extension and Attendant Recall will
be offered instead.
DPNSS1 Call Back When Free and Call Back When Next Used
DPNSS1 Call Back When Free and Call Back When Next Used are not
supported over VNS Bearer trunks. Network Ring Again or Network Ring
Again on No Answer may be provided instead, if Network Ring Again or
Network Ring Again on No Answer are configured over the VNS Bearer
trunks.
