Anticipating Israeli approval of the Camp David agreements, Egypt is calmly preparing for direct negotiations on a peace treaty, which are expected to begin next week.

The tranquility here presents a sharp contrast to Israel, where the Egyptian demand for evacuation of Jewish settlements in the Sinai touched off demonstrations in the street, court action against the government and bitter debate in the Knesset.

The only demonstrations here have been in support of the agreements. The overwhelming majority of Egyptians support the accords accepted by President Anwar Sadat and are looking forward to a speedy end to the struggle that has afflicted this country for 30 years.

Cairo newspapers have been publishing detailed accounts of the Knesset debate, to which there is no counterpart here. Egypt's own parliament, the People's Assembly, is to meet in special session after the Knesset vote to hear a major speech by Sadat in which the president is expected to outline the background to his acceptance of the agreements and the position Egypt will take in the direct talks.

Egyptian officials have been saying that negotiations must proceed on two levels - one concerning terms of the treaty between Egypt and Israel, the other on establishment of local authonomy in the Israeli-occupied West Bank of the Jordan and the Gaza Strip.

Press reports here have said that Egypt will ask that the Israeli military government be withdrawn as soon as the negotiations begin. The Camp David accords say the military government will be ended after election to establish local self-government for the inhabitants of the territories.

It is important for Egypt to be perceived by other Arabs as doing the best if can to achieve quick changes in the status of the occupied territories, to counter accusations that this country has abandoned the Palestinians and concluded a separate peace.

Egypt has sent an envoy to confer with King Khalid of Saudi Arabia and has conducted briefings for Arab ambassadors. As expected, however, it has shown no great concern over the outcries of Sadat's concern over the outeries of Sadat severest crities, whom the Egyptians have written off.

Led by Sadat, Eyptian officials are making it clear that negotiations over the status of the West Bank and the future of the Palestinians are going ahead whether or not Jordon and the Palestine Liberation Organization take part.

According to Boutros Chali, the acting foreign minister, Egypt is prepared to assume the role that was intended for Jordan in the negotiations over the occupied territories if Jordan refuses to participate.

A team of Israeli communications technicians is due here today, the first official Israeli representation since Sadat ousted the remmants of the Israeli military negotiatin team when talks brike down in July.

Israeli journalists, however, already have returned, moving freely about Cairo as they did last winter. The overnment has even accredited them to cover the annual Egyptian military parade on Oct. 6, the anniversary of the beginning of the 1973 war.

It seems to be a foreone conclusion to most Eyptians that peace is now assured. The Cairo papers are full of reports about potential development plans for the Sinai.
