addition, individual data bits can be placed within a byte along with don't care bits. Onboard clock circuitry, including a digital phaselocked loop, supports all H.100/H.110 clock modes including MVIP and SC-bus compatibility clocks. The local CHI supports PCM rates of 2.048 Mbits/s, 4.096 Mbits/s, and 8.192 Mbits/s. The Ambassador T8105 has internal circuitry to support either minimum latency or multi-time-slot frame integrity. Frame integrity is a requisite feature for applications that switch wideband data (ISDN H-channels). Minimum latency is advantageous in voice applications. Agere Systems Inc.
