system must be determined. If the intranet becomes overloaded, new calls
to the IP Trunk3.01 (and later) system fall back to normal circuit-switched
voice facilities so that the Quality of Service (QoS) does not degrade for
new calls.
IP Trunk3.01 (and later) is for intranet use only. IP Trunk 3.01 (and later)
provides virtual analog ISL TIE trunks between two Meridian 1 systems
in an ESN network, as shown in Figure 23 "The IP Trunk 3.01 (and later)
intranet" (page 91). IP Trunk 3.01 (and later) does not support modem
traffic except for Group 3 fax. The technician must configure the Meridian
1/ CS 1000M routing controls to route modem traffic over circuit-switched
trunks instead of over IP Trunk3.01 (and later).
