Dpnss 1 Services - Nortel BCM50 Configuration Manual

52 Chapter 2 System telephony networking overview
When the features are activated, users can:
• display a call charge
• redirect calls over the ETSI ISDN BRI/PRI line to the outside network
• tag malicious calls
Advice of Charge-End of Call (AOCE) — AOCE is a supplementary service available from your
service provider on ETSI ISDN BRI/PRI links. This feature allows the BCM user to view the
charges for an outgoing call after the call completes. This information is also reported to the Call
Detail Reporting Application. The information can be provided in currency or charging units,
depending on how the feature is set up by your service provider.
To invoke the feature, the user presses FEATURE 818.

DPNSS 1 services

The Digital Private Network Signaling System (DPNSS 1) is a networking protocol enhancement
that extends the private networking capabilities of existing BCM systems. It is designed to offer
greater centralized functionality for operators, giving them access to BCM features over multiple
combined networks.
Note: The DPNSS feature is dependent on which region loaded on your
system at startup and that a software keycode was entered to enable the
feature.
For more information, see:
• "DPNSS 1 capabilities" on page 53
• "DPNSS 1 features" on page 53
• "Private networking with DPNSS" on page 60
DPNSS 1 allows a BCM local node, acting as a terminating node, to communicate with other
PBXs over the network. For example, corporate offices separated geographically can be linked
over DPNSS 1 to other BCM nodes, bypassing the restrictions of the PSTNs to which they may be
connected. Connected BCM nodes can therefore function like a private network, with all features
of BCM accessible.
Note: BCM DPNSS 1 works as a terminating node only. BCM-to-BCM
DPNSS is not supported.
You can use DPNSS 1 features on any BCM telephone. On most BCM telephones, you must use
specific keys and/or enter a number code to access the features.
