Costs for D-channel/B-channel ratios ? Telco would have to give you that information. With the 1-D controlling many 24B, you do chance the disaster scenario where losing that physical line would kill signaling for the entire group....BUT how often has that happened to anyone ? Maybe Primary-D, secondary-D and then a bunch of 24B - if the telco and/or switch support it ? (I believe the TNT can, I'll check that too though).
