                        </font></span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span lang="EN-US"><p><font face="Times New Roman">&nbsp;</font></p></span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;;">  首先,建设综合关口局可提高网络的安全性。综合关口局可以对外屏蔽本地网的组网信息:在进行网络内部调整或扩容时,只需要协调本地网内部的变更,而对于和其他运营商网络的互通协调工作,可以只对关口局交换机作相应的改动。</span><span lang="EN-US"><font face="Times New Roman">

                        </font></span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span lang="EN-US"><p><font face="Times New Roman">&nbsp;</font></p></span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;;"> 二、网络现状。对于各大运营商,原有各本地网、长途汇接局、关口局与其运营商网络设备之间的联接都是网状结构。采用这样的互联方式,一方面使得网络结构复杂,层次不清晰,造成电路利用率低、网络的维护管理工作量大以及不方便网间结算等诸多问题;一方面,随着用户对电信服务的要求不断提高,运营商需要能够在网间互联设备上为用户方便快捷的提供智能增值业务及其管理和计费,通过网间互联设备的鉴权功能保护合法网间呼叫、拒绝不合法的网间话务,显然,原有的网间互联设备已无法完全满足需求。因此,各大运营商建立专用的综合关口局,以实现多运营商之间有效地网络分割及经营管理、网间结算和网间业务管理,是十分必要的。</span></p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;;">经公司多方调研,决定采用大唐</span><span lang="EN-US"><font face="Times New Roman">SP30iEx</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;;">作为综合的交换平台,</span><span lang="EN-US"><font face="Times New Roman">SP30iEx</font></span><span style="FONT-FAMILY: 宋体; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;;">完全满足构建综合关口局的设计要求:</span><span lang="EN-US"><font face="Times New Roman">
