Nortel Networks NN43001-314 - Manual (Page 395)

Group Dialing Plan 395
• The NRS is queried for a destination node IP address with which to
route the call over the Virtual Trunk. The main office node IP address is
returned because "501" is registered to the main office.
• The main office Call Server terminates the incoming Virtual Trunk call to
DN 3001 (or 3002) because "501" matches the HLOC of the main office.
• The Voice Gateway channel in the Branch Office provides IP-TDM
transcoding.
Branch User telephone (DN 3002) is in Local Mode
In this scenario, the following occurs:
• The MG 1000B Core handles the call processing of DN 3002.
• If no network outage or Signaling Server/NRS failure occurs, DN 3002
can still make or receive a call to or from any telephones in the Branch
Office and main office using UDP. However, DN 3002 cannot be reached
from the main office by using CDP. Refer to Local Mode scenarios for
CDP (
"When the Branch User telephone is in Local Mode" (page 385) )
and UDP ( When the Branch User telephone is in Local Mode ).
• By having UDP and CDP working together, GDP provides the
convenience of CDP and the flexibility of UDP.
