Hairpinning
Unlike the IP-TDM-IP connectivity option, hairpinning requires that all media processing
resources for a given call reside on a single TN2302 Media Processing circuit pack or a single
G350 or G700 Media Gateway VoIP Media Module. A hairpinned call is originally set up as an
IP-TDM-IP call, but once the set-up process is complete, no TDM resources are required.
However, resources on the Media Processing circuit pack or VoIP Media Module are required
for the duration of the call. A Media Processing circuit pack and a VoIP Media Module each
house an onboard Central Processing Unit (CPU) and Digital Signal Processors (DSPs).
Shuffling
A shuffled call relinquishes all TDM and media processing resources after call setup. Therefore,
the media stream of a shuffled call traverses only an IP network. This is the most commonly
used mode of connectivity between two IP endpoints in the same system.
Figure 57: Connectivity modes between two IP endpoints
on page 166 shows the various
modes of connectivity between two IP endpoints.
