There were 2 other good reasons to have a clec license, at least in the
rate-center type latas... (Chicago/Lata 358 comes to mind)...
1. was to play the reciprocal comp game with the ILEC... At least one CLEC's
entire business model was nearly completely based on this early on (Focal Communications)
2. was to have a folded modem pool where all the rate centers terminated into one
large modem pool. It was easy to turn up a few ds3s to a few tandem switches to receive
inbound calls from a large portion of the lata. After you got up and running and found the
'hot spots' you'd then turn up end-office trunks to each of those rate centers to take
advantage of the more favorable termination rates for #1.
Ah the good 'ol days of the Dial-up isp biz... I remember 20+ Ascend Max TNT's each humming
along with 16 inbound PRI's of dial-up...
If I remember correctly tho, in order to connect to the tandems you had to be able to provide
ss7 services. We got all of our ports out of a DMS500, but I do remember people using something
from cisco to emulate a switch (SCC maybe?) and back end all the dial traffic into 5800's....
