cctActiveInitialRxRate 1.3.6.1.4.1.9.9.163.1.2.3.1.14

Initial receive data rate for this call. If call is a synchronous digital call such as ISDN sync, this value is the data rate of the B-channel. If call is asynchronous, even if using a synchronous transmission medium such as ISDN, the value is determined by the resource providing the asynchronous processing. For modem calls, this value corresponds to the value of cmRXRate from CISCO-MODEM-MGMT-MIB, immediately after the modem has completed initial negotiations. This value does not change, even if the data rate varies during the call. This value will be zero until an initial data rate has been determined.
