said by Hahausuck:I believe that is dependent on the number of T-1's per site, if you will.
A T-1 can handle 24 calls, provided the rest of the channels are not being used for other purposes like data. Then it is a matter of oversubscription. Traffic engineering is used to determine actual loads and predicted loads, so that the carrier can plan sufficiently for upgrades.
Someone correct me if I am wrong, but that is my understanding of it.
Consider yourself corrected.
A T1 actually a DS1 (once it is handed off to the customer) if channelized out at 64K will only transport 24 calls and if it is a primary rate ISDN that number drops to 23 calls as the D channel requires a single 64K channel to handle call setup and teardown.
However in the non-analog PCS and cellular world the DS1’s can carry considerably more calls than a channelized DS1 due to the encoding of the analog voice at the handset before hitting the RF and in turn the subsequent decoding at the MTSO.
This is one of the reasons calls over wireless many times have the quality of two cans connected by a string.
