Trying to design a WAN to LAN connections. One of the part is to connect Cisco 7206VXR-NPE-G2 to Cisco 3845.
One option is to use E1 connection (as WAN), using Mix-Enabled T1/E1 Port Adapter (PA-MCX-2TE1) at the 7206 and 1 port T1/E1 Voice/WAN (VWIC2-1MFT-T1/E1).
The second option is to use Gigabit connection (as LAN), using GBIC-SX to GLC-SX-MM (Fiber) or using PA-GE to NM-1GE (Ethernet).
First question, is my choice of modules/PA correct? If so, I planned to have VoIP capability in the future, will they support it?
Last question, are these kind of product related questions allowed in here, or should I post this somewhere else? I am doing this as a design project, and if viable I might give my students a similar project case with real life product.
