Cisco 4-Port Async/Sync Serial High-Speed WIC

neerajsingh · ‎07-18-2007

As per the document of the above hardware, a speed of 230kbps can be achieved using PSTN lines. However it is not mentioned what end to end infrastructure we need to achieve 230kbps using PSTN lines.

what i understand that I need cisco 1800/2800/3800 series router and cisco Async/Sync High speed WICs at both end and PSTN line.

Could some have idea/implemented such a solution using above hardware/infrastrcuture to achive 230kbps using PSTN lines.

Hi,

Many modern devices can exceed the low known speeds of asynchronous communication (38,400 and 57,600 bit/s being common, and 115,200 and 230,400 bit/s making occasional appearances) while still using RS-232 compatible signal levels.

Hi Mohammed,

Thanks for ur reply. Can i assume that using cisco 1800/2800/3800 series router and using cisco High speed WIC(which supports 230kbps), can i achieve 230kbps end to end using PSTN or do i need some external modem which along with cisco device.
