Had to fix some ends on the extended cabling, cable tester showed pins had an error.
Label the patch cables, because in the end you want to have OSPF neighbors on your serial connections, match the interface with the ones plugged and marked, easier to track when testing
For the final product, you want green lights on the NIU, any amber call your service provider, dispatch out if their auto test says the circuit is good. I've come to the conclusion their test is a pass or no pass; best advise get a visual on the NIU.

Depending on who you are, email me for a script, worst I can say is no. If I know you, odds are I will send you not only the script by my SOP and actual configurations.
VWICs installed but not configured, here is sample for configuring VWICs on 3800:
! first card is a dual port VWIC you need to specify if it's a T1 or E1 and 0 is for motherboard in slot 0
card type t1 0 0
!Tip US and Japan use B8ZS different for E1 setup and most TelCom use ESF, on the DS3 controllers m23 and c-bit framing
controller T1 0/1

Trends and Analysis
We use PPP so we can bundle the T1s, our node routers are ASR 1013s and 7609s. sh ppp multilink. We replaced all of our 3700, 3800, and 3900 series routers with the ISR 4451-X to prepare a school for a fiber circuit, about 750 school sites. About 50-70 schools still have serial connections, pending trenching and permits for the fiber connections from AT&T. I've noticed a trend that when the T1s are bundle, the 4451-X has dropped some interfaces from the bundle. The solution has been to reload the school's routers to get the T1s back in the Multilink bundle. If you are capturing the same thing please contact me.
With our monitoring tools, there seems to be an issue some of the lower end HP switches. We lose managed APs and the trend is for our IT LAN Techs to reboot the edge switch. Do you have any similar issues?
Wireless, the mDNS has an ACL limit, and I've seen how Bonjour and Apple TV get filtered out. We upgraded the WLAN controller 5508 to a certain code and had our System Admin upgrade the code on the iPads and Apple TV. If you want to share and compare some IOS standard contact me.
For those 50-70 sites that aren't on fiber, we started deploying the Cradle Points. It looks good on paper however you need to take into account the LTE coverage for the area you are deploying. I've deployed them to sites where Verizon provides great service and to some sites where they are better off with 4 T1s. Lessons learned from Cradle Point, cell towers provide best effort and the more users connect the more sharing you will experience.
