my quest is what is the technical differnece b/w Serial and Ethernet interface interms of WAN connectivity as we are plannig to move from stm1 serial connection over to gigabit ethernet interface

Re: WAN connectivity

There are many differences, so that it can't be summarized in this small space.

You can read about on the internet, or just rely on your lead engineer (if you have one),

How technical?  Each has different bandwidth overheads.

From a practical standpoint, if you're obtaining a GigEtherent handoff with (say) 150 Mbps of contracted bandwidth vs. your STM1's 155 Mbps, you probably want to shape for the contracted rate.  Generally, it would be difficult to see much of an effective bandwidth difference if the GigEthernet is rate-limited to such a similar value as the STM1.  However, often the contracted bandwidth, on the GigEthernet, can be easily and quickly changed.

One subtle difference, equipment that supports STM interfaces is more likely to offer extensive QoS features than equipment that supports Ethernet interfaces which can be especially important for WANs.
