Hardware Reference Manual
– T1 rates: 1.536, 1.544, 3.088, 6.176 Mbit/s
– E1 rates: 2.048, 4.096, 8.192 Mbit/s
– Supports linked-list buffer processing
– 16-DWord Tx DMA FIFO
– 16-DWord Rx DMA FIFO
– 4-DWord burst of Rx descriptors
– 3-DWord burst of Tx descriptors
– n-DWord burst of configuration blocks
– Compatible with T1/DS1 24-channel and CEPT 32-channel PCM byte format
– Concatenation of any, not necessarily consecutive, time slots to superchannels
– Support of H0, H11, H12 ISDN-channels
– Subchanneling on each time slot possible
(n is unlimited according the MUNICH128X, but internal port arbitration may lead to
a lower typical burst size of 4 or 8 DWords)
independently for receive and transmit direction
