摘要： A network device may provide secure fallback operations. The device includes a port allowing the device to communicate with a network and a processor to generate a security credential, provide the security credential to a call manager during initialization, and provide the security credential to a secondary device during fallback operations. The network device may include a memory to store the security credential and routing information for fallback operations.

摘要： The invention relates to a process for making polyethylene terephthalate (PET) from ethylene glycol (EG), purified terephthalic acid (PTA) and optionally up to 6 mol % comonomer, using a mixed metal catalyst system and comprising the steps of a) esterifying EG and PTA to form diethyleneglycol terephthalate and oligomers (DGT), and b) melt-phase polycondensing DGT to form PET and EG, wherein the catalyst system substantially consists of 70-160 ppm of Sb-compound, 20-70 ppm of Zn-compound, and 0.5-20 ppm of Ti-glycolate as active components (ppm metal based on PET). With this process that applies reduced amount of metal catalyst components PET can be obtained with high productivity, which polyester shows favourable colour and optical clarity, also if recycling of EG is applied within the process.
摘要翻译：本发明涉及使用混合金属催化剂体系从乙二醇（EG），纯化对苯二甲酸（PTA）和任选多达6mol％的共聚单体制备聚对苯二甲酸乙二醇酯（PET）的方法，包括以下步骤：a）酯化EG 和PTA以形成对二醇二乙二醇酯和低聚物（DGT），和b）熔融相缩聚DGT以形成PET和EG，其中催化剂体系基本上由70-160ppm的Sb-化合物，20-70ppm的Zn化合物，和0.5-20ppm的作为活性成分的Ti-羟乙酸酯（基于PET的ppm金属）。通过该方法可以减少金属催化剂组分的量，可以以高生产率获得PET，该聚酯显示有利的颜色和光学透明度，以及在该方法中应用EG的再循环。
