此前中国联通董事长常小兵在深圳出席2011年中国IT领袖峰会时曾透露：在今年5月17日之前，中国联通将在国内56个城市开放HSPA+，传输速率将升至21Mbps，此举被看做联通2011年的一项重点工程。而上月末我们就曾借助一个新加坡HSPA+无线上网卡偶然发现沈阳部分地区拥有21Mbps 3G无线高速网络.
辽宁联通沃3G 21M无线上网卡上市媒体沟通会
就在昨天，5.17世界电信日即将到来之际，辽宁联通在万豪酒店举行了沃3G 21M无线上网卡上市媒体沟通会，证实了我们之前的一切猜想。沟通会现场笔者再次亲测了联通的HSPA+制式高速3G无线上网，21.6Mbps的高速下行峰值速率就对名不虚传，1.7MB/s的迅雷下载速度，让现场所有媒体朋友为之惊叹，这个速度是联通现有3G网络的3倍，是普通家庭2M宽带的10倍，直观一点的说下载一部1G的高清电影文件不足十分钟就可搞定。
据悉目前中国联通在国内包括沈阳、大连在内的56个城市开放了HSPA+网络，最大21.6Mbps的下行速率意味着用户拥有更大的带宽，可承载更高品质的上网业务之外，视频电话、在线直播等移动多媒体业务，也同样完美呈现，可以说联通此举将提升人们的工作效率、提高生活、娱乐品质，带个人们更好的移动互联网体验。
另外针对消费者所关心的资费问题，此次推出的21M极速无线上网卡也做了不少优化。最低套餐为每月80元/1G流量，支持套餐自动升级。如用户预存1300元话费还可单独获赠一套价值423元得21M高速无线上网卡设备及USIM资费卡，这也是中国联通为优惠消费者的又一重大举措。
可以说联通沃3G 21M无线上网卡前所未有快人一步的高速网络在配合合理的套餐资费，足以让你随时随地畅游3G互联生活。目前在沈阳、大连相关营业厅及沃品牌形象店均设置有沃3G 21M无线上网卡体验区，感兴趣的朋友可以眼见为实、切身体验下HSPA+的速度感！

Connecting with AudioCodes TP-260
The TrunkPack® (TP)-260/SIP is a PCI VoIP communication gateway board from AudioCodes. You can configure this device to work with Brekeke PBX to leverage your broadband phone service connections by automatically routing local calls from cell phone and land line to VoIP service provider and vice versa. This document will explain how to set up the Automatic Route Selection (ARS) for the TP-260/SIP. For more information on this product, please go to http://www.audiocode.com
The TP-260 User’s Manual describes the installation and use of this unit. It can be found in the CD (“TrunkPack Digital Boards & VoP GW Series”) that shipped with the unit.
The TP-260/SIP has an embedded web server which allows you to easily view and manage your gateway’s settings through a web browser. Please follow the instructions below carefully.
The following is a guide for configuring the TP-260/SIP to work with Brekeke PBX to allow you to send and receive VoIP calls. Please note that only required parameters, within Brekeke PBX and SIP server domain, are discussed here. Most of them are self explanatory and there is no need to describe them all in details. You can always consult the User’s Manual of this product if you need in-depth technical information.
The document in this section is written based on “Mediant & TP Series SIP User’s Manual” by AudioCodes, version 4.6, Document#: LTRT-68803
A quick glance on the main menu bar, you will see 7 menus as shown below.
Set up IP, SIP parameters, coder name, routing and trunk group tables.
Configure the gateway’s general parameters
Configure the gateway’s proxy and registration parameters
The current version of Brekeke PBX supports three codecs: g711Ulaw64k, g711Alaw64k and iLBC. The g711Ulaw64k codec is the most commonly used.
Configure DTMF and dialing parameters
Configure general parameters for routing tables
Configure the gateway’s Tel -> IP routing tables. It’s used to route incoming telephone calls to IP addresses when proxy server is not used.
This table is used to route incoming IP calls to trunk groups based on any combination of the destination phone prefix, source phone prefix and source IP address.
You can define up to four different Tel Profiles. The gateway’s B-channel characteristic is defined based on each Tel Profile.
You can define up to four different IP Profiles. They are used in the Tel to IP and IP to Trunk Group Routing tables to associate different profiles to routing rules.
Use this table to assign trunk groups, profiles and logical telephone numbers to the gateway’s E1/T1 B-channels.
This table is used to determine the method in which new calls are assigned to B-channels within each trunk group.
These menus allow you to set up the gateway’s channel parameters for voice, fax, RTP and IPmedia.
This menu allows you to configure the parameters of a specific trunk. It’s very important that you set the T1 parameters in this menu to match with the settings of T1/E1 trunk.
After applying trunk settings, you should see the trunk status like this which indicates no alarm on trunk 1.
If you have encountered other alarm(s), please refer to the trunk status color indicator below to diagnose the problem before proceeding to the next section.
