Feature Packaging - Nortel Meridian Meridian 1 Feature Description And Administration

Trunk Optimization
Trunk Optimization is not supported across the Asia Pacific interface, but
interworks transparently. In other words, trunk optimization will not be
observed at the Asia Pacific ISDN. The call will appear to be static, not
undergoing any modifications.
T309 Timer
The Meridian 1 supports the T309 timer on PRI trunks for all Asia Pacific
interfaces.
Virtual Network Services (VNS)
It is not possible to configure an Asia Pacific D-channel as a VNS D-channel.
However, the voice connection through the Public Exchange of a VNS call
may use a PRI COT or DID as a virtual TIE trunk.
