3.1.5 Private ABC sub-networks using ABC trunk groups on IP
The ABC trunk groups on IP provide an alternative to the TDM leased lines to connect ABC sub-
networks within a network consisting of ABC sub-networks (i.e. an ABC supranetwork).
The ABC trunk groups on IP enable a fully-fledged IP solution for communications within an ABC
supranetwork. Within ABC sub-networks, the inter-node IP links are provided by ABC logical links on
IP.
Via these IP links, the ABC supranetwork forms a global IP network where IP communications are
ensured from their beginning to their end within the ABC supranetwork.
Within an ABC supranetwork, up to 250 ABC sub-networks can be connected via ABC trunk groups on
IP.
– When there are too many Communication Servers in an ABC sub-network (OmniPCX
Enterprise product limit)
– For customer deployment and organization (per area)
– For numbering plan issues (within an ABC sub-network, the numbering plan must be
homogeneous)
Services provided by the ABC trunk groups on IP are:
– Same level of services as TDM leased lines
– Direct RTP between IP devices located on different ABC sub-networks
– Call Admission Control (CAC) over IP
