This is a call that is to be routed on your private network (not using the PSTN), using LOC codes. You have a remote site that is designated as 420 (in Dallas area?), and it is using 4 digit extensions. So, after dialing your AC2 + 420, the system continues to wait for another 4 digits (420xxxx) before processing the call. It will save the last four to send with the call.
We see that your DID block for that location is 684-5373 thru 684-5375 and 684-1663 thru 1670. That info, plus the LDN, is used for off-net conversion. So that if the call cannot be completed over your private network, it can send it over the PSTN and have it either convert to a DID number or send it to the main number at that site.
