ISP Glossary:
Heterogeneous Data sources - [TELECOM Digest Editor's Note: John, I am curious about something. In an area where there is a predominant LEC (everywhere, I suppose) and it negotiates things regards its customers (such as 'bill and keep' as one example) what about the independent telcos in the same area? Are they obligated to go along with what the LEC 'negotiates'? PAT]The interconnection agreements among ILECs all date from the regulatedera, so they were all overseen by state utility commissions. Sincethey were supposed to be cost-based, they often depended on how manymiles of the interconnecting trunks were owned by each telco.Now that we have wireless, paging, and CLECs, and transmission costshave gotten so low that it's common to switch calls 50 or 100 milesfrom the subscriber's location, it's all gotten a lot more complicated.John R.
