ST 的 CPE ADSL 调制解调器是你的最佳选择ST

简介：

问：ST50150 WLAN方案对WLAN NIC是否有特殊要求？目前支持的WLAN卡有哪些？
VODSL和VoIP方案是否已成熟，可以演示吗？有实际的应用吗？
答： The current 50150 solution comes with reference designs for 802.11b/802.11g support.
Interfaces are standard and multivendor WLAN cards/modules are supported.
VoDSL and VoIP can currently be supported using ST"s family of standalone ADSL produ

问：我使用20156TQ-C1做ADSL测试仪仿真ATU-C时，发现上电有时不能正常复位，要上电后按一下复位键，请问如何解决？
答： Do contact the local technical support.  
It is probably related to power-on reset sequence.  Usually we need to release the reset signal of the AFE chip, then release the reset signal of the DMT chip.

问：设计过程中，整个ADSL路由器的电源总功率是多少？
答： ETNA solution: 9VDC, about 380mA (total <3.5W)

问：ST有无结合IP分享，频宽管理等功能的ADSL芯片
答： These functions depend on the network SW stacks running on the integrated network processor.
ST has a standard turnkey solution which supports various flavours of NAT/PAT, NAT+bridge,..(for IP sharing).

Various ATM Qos levels are supported.

问：目前无线上网的速率有多高！
答： It depends on the service provider.

问：1. cpe的主芯片组是单芯片还是多芯片？
2。主mcu接口是否集成ethernet PHY?
3. wlan应用中是否提供pcmcia接口？或者只有utopia接口？
4。现有firmware的api是否对oem客户全部开放？还是只开放GUI?
5. 现有封装是否BGA?对生产线要求有多高？
答： 1. Our ADSL ETNA MTC50150 chipset is a single chip solution (build in CPU + DMT), with external AFE (build in Tx driver and Rx Amp)

2. Ethernet PHY is external, ST100E from ST.

3. Current chipset support ISA interface.

4. GUI, on

问：请问ADSL的最高接入带宽是多少？？
它是否能实现固定IP。如何实现？？
答： The 8M bits downsteam is the standard. But using same CO and CPE of ST, we can reach about 12M bits downstream.
ST CPE can support the static IP. Anyway, it is depended on the ISP.

问：抛开技术不说，你们的产品在价格上有什么优势？
答： Pls contact us directly.

问：请问﹐modem在播号过程中波型是怎样变化的?无播号音但可以成功连接是什么回事?谢谢﹗
答： ST ADSL uses DMT (discrete multi tone) technology.  When power up, CPE modem will send the activation tone to the line.  When CO (Central Office) modem detects the activation tone, both CPE and CO modem will start the initialisation (li

问：ST 的CPE ADSL 用的主要芯片，芯片组及其价格
该ADSL产品的主要技术指标。
答： 价格请洽ST销售!
