Hi.. I am ordering some network modules, BRI modules and analog/digital modules for the cisco 3660 router. I am a bit confused about the product discription that cisco gives on the website. as I understood, the NM are base modules , which should be populated by WAN/Voice/Ethernet interfaces. Inthat case, what does " 2 10/100 Ethernet 1 WAN card slot Network Module" mean? Cna I ahve a ethernet interface and a WAN interface (T1 CSU/DSU) on the same NM? Also how do I know whether I need a Anolog Modem module or a digital modem module as I am planning to have ISDn interface and also anolog module on te same NM. Thanks in advance.
