2.82.2 Distributed Control Network
Description
In the Distributed Control Network, each iPECS system maintains control over the devices
registered to it. The networked systems communicate employing QSig over ISDN Lines or H.450
over IP Lines for basic networking capabilities and the proprietary iPECS protocol for the
advanced networking features. QSIG employs ISDN PRI channels only with support for ESTI
standards ETS 300-237/238/256/257/260/261/361/362/363/364.
As a member of the network, you will have access to resources of other systems in the network
such as outside Lines, Stations and Paging. A Network Numbering Plan determines the system
