VO1P网络整和的优势 1. 无需添加第三方的语音网关，所有语音通信设备都通过NEC的7号智能7号信令CCIS直接入企业的专有网络（IP网络边缘）。 2. 接入方式： 网络中，如果现有NEAX 2400 设备，则只需添加硬件板卡即可(IP PAD + VCT) 。 如果现有非NEAX 2000/2400设备，则可以在原有设备前添加NEAX 2000作为IP 网络的接入。 3. 所有网络中的NEAX 2400/2000 IP PBX采用NEC最新科技的CCIS over IP组网方式。 这8台 IP PBX可以实现功能上的全透明，如： 统一的编号方案，中继设施共享，话务台共享，语音信箱共享，集中的管理维护，集中的计费等。由于大量通话在网络内部进行或转接，可以节省相当的长途话费。 4. 使用CCIS over IP更重要的是免除了使用第三方语音网关设备带来的通话建立阶段的较大时延与可能出现的各类不同厂商之间产品兼容性的问题， 使网络内的用户感到象使用一台交换机一样方便。 由于网络中间环节的减少，在网络出现问题时，也可以方便的通过NEC的专用维护管理工具第一时间查错并进行修正。 NEC先进的LCR技术可以帮助客户在内部网络出现问题时自动将呼叫转接到PSTN上。 5. 我本人认为最好是将使用LC与COT 连接的设备全部接入到网络内，因为CCIS over IP的方式最大可以支持255个节点的连接，而功能上传统的LC/COT连接只能作为NEAX 2000/2400的分机来使用，无法实现功能透明，但仍可以进行正常的通话。 当然可以根据客户的使用情况，对客户语音网络进行逐步的升级。 6. 网络中无法看出带宽，请注意指出每一路语音在通信时占用大约20K左右的带宽，通话完成后随即释放。同时建议客户采用QoS保证语音质量。如：为TOS为7的包保留以部分带宽。

| Re. 发表于2005/4/11 12:57:00 Advantages of VOP1 network integral harmony 1.It is not necessary to append the sound gateway for third partner ,all the sound telecommunication equipment can directly get access to special network of enterprises through No.7 intelligence of NEC ,No.7 signal order of CCIS.

| Re. 发表于2005/4/11 13:03:00 2.Access mode : if there is existing NEAX2400 equipments ,you can only need append hardware board card in network .if there is not existing NWAX2400 equipments ,you can append NEAX2000 for original equipments as the IP network access .

| Re. 发表于2005/4/11 13:27:00 3.In all network ,NEAX2400/2000 IP PBX adopt net organization manner of CCIS over IP of the NEC latest sci-technology . These 8 IPPBX can realize the total transparency of function ,such as :integral number program ，share of relay facilities , share of telephone traffic ,share of sound mail box, concentrated management maintenance ,concentrated charging . Because the numerous call can switch or get though in interior network , the long-distance telephone charging can be saved .

| Re. 发表于2005/4/11 13:52:00 Because of the use of CCIS over IP ,we can avoid the time interval caused by use of the third part sound gateway equipments in stage of establishing calls ,and the products compatibility problems created by various manufacturers .the consumers in network feel that it is convenient to use it as using a telephone switchboard. Because reduction of network courses ,when the net problems occurred ,we can still through the special repair management tools of the NEC checｋerrors and modify them quickly. The advanced LCR technology of NEC can help the clients to switch the calls automatically to PSTN when problems of the interior net appeared.

| Re. 发表于2005/4/11 20:32:00 5. I think all the equipments that connected LC with COT are accessed to network ,because in CCIS over IP way the net can support 225 notes joints 。Traditional LC/COT joints are used as NEAX 2000/2400 extension , and don’t realize the functional clarity but still can get the normal call through . Of course ,we can upgrade gradually the clients sound net according to the usage of clients。 6 .In network we can’t see the bandwidth ,pay attention to point out every sound can occupy about 20K bandwidth ,and after finishing call immediately release . At same time ,it suggest that the clients adopt QOS to grant the sound quality .
