it begins with;
This document describes the configuration of the 4-port 10/100BASE-TX
Ethernet switch on Cisco 1711 and Cisco 1712 Security Access routers running
Cisco IOS Release 12.2(15)ZL and higher, and the Cisco WIC-4ESW interface
card supported on Cisco 1721, Cisco 1751, Cisco 1751-V, and Cisco 1760
routers, running Cisco IOS Release 12.3(2)XC and higher.
Since these run Call Manager, maybe I can use them for a voip deployment
instead with 7912's. The 4ESW is a pricey option even 2nd hand so I was
looking for experience above a T1 before we made the purchase.
