The 3.3V Multiple Rate Digital Switch (MT89L86) is pin compatible with MITEL's 5V MT8986 and retains all of its functionality. This 3.3v device is designed to provide simultaneous non-blocking connections for up to 256 64kb/s channels or blocking connections for up to 512 64kb/s channels. The serial inputs and outputs of MT89L86 may have 32 to 128 64kb/s channels per frame with data rates ranging from 2048 up to 8192 kb/s. MT89L86 also provides per-channel selection between variable and constant throughput delays allowing voice and grouped data channels to be switched without corrupting the data sequence integrity.
