The offices of elder and ministerial servant were restored to Witness congregations in 1972, with appointments made from headquarters (and later, also by branch committees). It was announced that, starting in September 2014, appointments would be made by traveling overseers. In a major organizational overhaul in 1976, the power of the Watch Tower Society president was diminished, with authority for doctrinal and organizational decisions passed to the Governing Body. Since Knorr's death in 1977, the position of president has been occupied by Frederick Franz (19771992) and Milton Henschel (19922000), both members of the Governing Body, and since 2000 by Don A. Adams, not a member of the Governing Body. In 1995, Jehovah's Witnesses abandoned the idea that Armageddon must occur during the lives of the generation that was alive in 1914 and in 2013 changed their teaching on the "generation".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the offices of restored to the Witness congregations?
Ah, so.. 1972

The MC controls the conferencing while it is active on the signaling plane, which is simply where the system manages conferencing creation, endpoint signaling and in-conferencing controls. This component negotiates parameters with every endpoint in the network and controls conferencing resources. While the MC controls resources and signaling negotiations, the MP operates on the media plane and receives media from each endpoint. The MP generates output streams from each endpoint and redirects the information to other endpoints in the conference.

Ah, so.. the signaling plane

A sequence of events, or series of events, is a sequence of items, facts, events, actions, changes, or procedural steps, arranged in time order (chronological order), often with causality relationships among the items. Because of causality, cause precedes effect, or cause and effect may appear together in a single item, but effect never precedes cause. A sequence of events can be presented in text, tables, charts, or timelines. The description of the items or events may include a timestamp. A sequence of events that includes the time along with place or location information to describe a sequential path may be referred to as a world line.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can a sequence of relationships used to describe a sequential path be referred to as?
Ah, so..
unanswerable
