One our sites acquired a new T1 from our Isp, but we don't have the port to accommodate it on a Cisco 2800, our vendor wants to install:
"you can replace the existing NM-HDV2-1T1/E1 (the big module in the lower left corner) with a NM-HDV2-2T1/E1. It's basically the same module, but with an additional T1 interface on it"
Just want a second opinion, can't we replace one of the FXO cards with another T1/E1 card? This is an addition to our existing MPLS circuit. Thank you.
