DS3/DS1 Backbone/Trunk capacity planning principles, whether across a Frame Relay Backbone or Cisco 7000 hdlc trunk network are still the same. It's just as easy to over configure DS3/DS1 Cisco HDLC trunks as Frame Relay trunks.
I would have a tendency to disagree with you here, but que sera, sera.
Potentially at issue here is not Frame Relay networks as a transport but that a Cisco 7000 can not scale properly to support 120+ end-users. :-) Modern Frame Relay switches: 1) have sub-msec latency 2) can support multiple trunks at DS3+ (to include ATM) 3) are not burdened with processing any of the IP layer 3 nor routing overhead 4) because of 3 have a cost per port that is 300 to 400% less than a Cisco 7000 5) can have it's backbone shared across multiple services thereby reducing
both
capitalization and bandwidth expense 6) allow ISP to pass the cost savings on to customers
I partially agree with your points above, but still maintain that it is much easier to sloppily engineer a frame-relay network than one consisting of point-to-point links. My $.02. - paul
