DMC
This flag enables or disables the feature "DMC Interworking with HiPath 4000 Systems" (in
short "DMC"). In a network with HiPath 4000, DMC enhances the voice quality between IP com-
ponents (endpoints, gateways).
DMC is supported via networking protocols SIP-Q V2 and CorNet-NQ. In HiPath 3000 V8 and
HiPath 4000 V5 and later systems, only SIP-Q V2 protocol is used for IP networking between
these systems and only CorNet-NQ is used for TDM networking. CorNet-IP protocol is no long-
er supported.
DMC should be disabled in a homogeneous HiPath 3000/5000 network. If a network with Hi-
Path 4000 systems (version 2.0 or later) exists in which DMC is configured, the DMC feature
should be enabled in the HiPath 3000/5000 systems.
The HFA endpoints registered at the HiPath 3000/5000 system and the HiPath 3000 system
itself are then in a position to accept DMC connections set up by the HiPath 4000 and its HFA
endpoints. Even if the DMC feature is enabled, DMC is not performed between HiPath 3000/
5000 systems.
Note that enabling DMC results in a reduction of DSP channel resources. This means that only
about 80% of the channels will be available for connections per DSP in a HiPath 3000 system
(for example, 6 channels instead of 8, 12 channels instead of 16, 48 channels instead of 60).
