The best module to use is determined by what format the presentation is on the NTE. MPLS allows all sorts of circuit types to connect to the cloud. (In the UK, we're typically given frame relay circuits, and usually our ISP presents us with an NTU which has a serial connection - so we use WIC-1T or WIC-2T. But it varies from ISP to ISP)
Across our European sites, we have been presented with RJ45 Ethernet, X.25, G.711 coaxial cable...
You need to ask your service provider what presentation will be on the NTE. You'll then know (or it will be easier to tell) which WIC to order and install.
EDIT: Sorry, just read Part 1 of this thread. There may be an SFP module you could use too; you're not restricted to using WICs. But my original point still stands; without knowing what media you're being presented with at the NTE, you can't decide which module or WIC to buy.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
[toc:faq]Introduction:Netdr is a tool available on a RSP720, Sup720 or
Sup32 that allows one to capture packets on the RP or SP inband. The
netdr command can be used to capture both Tx and Rx packets in the
