Hi All,

Hi

Cisco 2503 contains Synchronous Serial ports which basically supports either 64K or 128K.

We normally see synchronous ports in WIC - 4AS/8AS bundle where you got the option to operate only either in 64k or 128k.

Hello,

if you are referring to the two serial interfaces on your 2503, these are high-speed serial interfaces, which support speeds up to 2048kbps, or roughly 2MB.

Check this link for more details:

Not saying you are wrong or anything without reading your link, but the high speed interfaces support 4, not 2.

I believe it is a question of being careful with terminology. The high speed serial interfaces support up to E1 rates (2048) in each direction or a total of 4 Mb bidirectional total throughput.
