Q. Does Cisco 1801-M support the PSD mask required to comply with the Annex M standards in the United Kingdom?
A. No. Currently there are no plans to support this.
Q. What is INP?
A. INP stands for Impulse Noise Protection. Support for INP allows the CPE to provide error-correction capability for impulse noise. The unit for this parameter is in number of symbols. Support for up to 16 symbols is provided by an amendment to the original G.992.5 standard and is referred to as
extended INP function (G992.5-addemdum II edited on May 2005). Support for optional INP capability of at least 16 DMT symbols (INP = 16) protects against impulse noise of up to 4 milliseconds. Increasing the INP also increases the latency.
Q. Does the Cisco 1800 Fixed-Configuration series support
extended INP functions?
A. All the platforms support INP, but only Cisco 1801-M supports the
extended INP functions.
Q. What do I need to know about INP support on the Cisco 1800 series Fixed-Configuration routers?
A. With Cisco 1800 Fixed-Configuration routers, customers may experience lower than expected downstream rate when INP is enabled on the DSLAM. This is due to a limitation with the MTK20196 chipset. This issue is addressed with the Cisco 1801-M platform, using the newer MTK20196P chipset.
