164 How the Branch Office feature works
The licensing feature applies only if more than four IP Phones are in
Local Mode at the same time. If four or fewer phones are in Local Mode
simultaneously, the licensing feature is not activated.
Testing the telephone in Local Mode
From Normal Mode, a Branch Office user can use Test Local Mode to test
telephone functionality in Local Mode. The user can perform the test at any
time and does not require a password. This test is invoked from the Internet
Telephone.
Nortel recommends testing Local Mode operation after changing the
provisioning for a telephone on the MG 1000B.
To ensure that users do not forget to resume Normal Mode operation,
the MG 1000B TPS redirects the telephone to the main office to return
the telephone to Normal mode. This occurs if the telephone remains
registered to the MG 1000B Call Server in Test Local Mode for ten minutes.
Alternatively, the user can select Resume Normal Mode from the Options
menu.
If a Branch Office phone in Test Local Mode logs into another Branch Office
TN through Virtual Office, makes an ESA call and is redirected (for example,
their location isn’t known), the phone is correctly redirected to its original TN
to complete the call. When the ESA call is complete, the phone immediately
reregisters with the Main Office rather than remaining registered to the
Branch Office for 10 minutes.

Administration (NN43001-613)NTP.
Virtual Trunks
In order for endpoints in the CS 1000 network to access endpoints in local
mode at the Branch Office or to access the PSTN at the Branch Office,
Virtual Trunks are used over the LAN/WAN.
Virtual Trunks are software components that provide the trunking features
of the Meridian Customer-Defined Network (MCDN) feature set. Access
to PSTN digital or analog trunks at the Branch Office occurs through the
MCDN Virtual Trunk.
For more information on Virtual Trunks, refer to IP Peer Networking
