Very sorry for the late answer. Your Network at that time probably was a combination of analog and digital switches that used SS7 (circuit and non-circuit) signalling to setup telephony calls.
Your Network is no doubt using IP / Sigtran / MPLS(-TP). This will help with Traffic Engineering and your Grade of Service (GOS).
