When a Terminal is placed on hold, the Music on Hold comes from the system where the

Terminal resides.
When a trunk is placed on hold, the Music on Hold comes from the system where the trunk

resides.
External Paging uses an output on the CD-CP00-US of the Primary System.

A PGD(2)-U10 ADP must be used if External Paging is required in the Secondary Systems.

License information in the Primary will be copied to the Secondary site when doing

database duplication.
Duplicate license information in the Secondary System is available for only seven days.

After seven days, the license expires. To renew the license, a connection to the original

Primary site must be re-established. (Once the connection to the Primary is recovered, if
fail-over occurs again, the license is once again enabled for seven days to the new Primary
System.)
If the original Primary site is in the NetLink network as a temporary secondary, the license

information is available.
If a user wants to enter another additional feature license, it needs to be entered on the

original Primary System.
When fail-over occurs, the Primary System is changed to another communication server.

The IP applications do not know the new primary IP Address, so the following features are
disabled after fail-over:
SMDR

ACD-MIS

SIP Terminal

Soft Phone

IP K-CCIS

The following Programs are not updated by the Primary System during fail-over :

Program 10-01, Program 10-02, Program 10-12, Program 10-13, Program 10-14, Program
10-15, Program 10-16, Program 10-45, Program 51-01, Program 90-01 or Program 90-09
Data in SRAM area is not transferred to the Secondary Systems during fail-over, therefore

when fail-over occurs DND and Caller ID History may be lost.
Mobile Extension is supported only when using the PRI installed in the Primary System.

When a Secondary System with an ETIA or RTB assigned is added to a NetLink network,

the Primary Systems database does not replicate the data in Programs 10-55 or 90-61.
When using Netlink and UCB, the trunks and extensions on the remote sites are not

supported for UCB (Version 2.50 or lower).
