Configuring Drop and Insert Multiplexing
To use this feature, WAN ports 1 and 2 must be active and licensed for use. Drop and insert supports one-to-one
mapping of 1 to 24 voice-carrying DS0s on the PBX interface to the equivalent DS0s on the network port. The
PBX is connected to WAN port 1 and the DS0s are mapped to the carrier facility on WAN port 2.
In this example, DS0 channels 1-10 and 18-24 from WAN links 1 and 2 are configured for drop and insert traffic.
The remaining DS0 channels (11-17) are available for IP traffic.
