Chapter 2 — Feature descriptions
Meridian 1 to New Zealand NEAX-61 ISDN PRI Connectivity
This feature provides an ISDN Primary Rate Interface (PRI) between a
Meridian 1 (SL-1) and New Zealand NEAX-61. The design in based on the
international 30B + D PRI configuration.
The NEAX-61 interface will support calls from ISDN BRI sets within the
MCDN. These will be able to call out to and receive calls from the Public
Switched Telephone Network (PSTN), also called the ISDN public network.
Operation will be as though the call was a tandem trunk call.
Although ISDN BRI trunks to the NEAX-61 are not supported, any ISDN
BRI trunks supported to other interfaces will be able to tandem to the PSTN
transparently. Feature operation will appear to the user as though the call was
from a normal PRI network trunk to the PSTN.
Network Wide Listed Directory Numbers
This feature enables LDNs to be recognized network wide when Network
Attendant Service (NAS) is used. The same LDNs must be configured in
multiple nodes. Network LDN is defined on a customer basis.
This feature is supported over ISDN BRI trunk DSLs.
Night Service improvements
All calls remain queued for night service
This feature allows all calls that are queued for an attendant when night
service is entered, to remain queued in order to be presented to the night DN.
This feature is supported for ISDN BRI-originated calls; however, the
displays on the ISDN BRI terminals are not updated to reflect the call
modification.
Automatic timed reminder recalls to the night DN
This feature allows any recall that times out during night service, to be
presented or queued to the night DN. This applies to slow answer recall, call
waiting and camp-on calls extended by an attendant, and camp-on calls
extended by a terminal.
This capability applies to external call only, since there is no internal recall to
a night DN unless done by NAS routing.
