• Two 150 Mbps Ethernet links on one 28, 40, 50 or 56 MHz channel.
• Two 190 Mbps Ethernet links on one 28 MHz channel.
• Two 200 Mbps Ethernet links on one 40 or 56 MHz channel.
• Two 300 Mbps Ethernet links on one 50 or 56 MHz channel.
• Two 75xE1, 93xE1 or STM1 links on one 28 MHz channel.
• Two 100xE1, 127xDS1, STM1 or OC3 links on one 40 MHz channel.
• Two 127xDS1, OC3 or 2xOC3 links on one 50 MHz channel.
• Two 75xE1, 100xE1, STM1 or 2xSTM1 links on one 56 MHz channel.

DAC 3xE3/DS3M
DAC 3xE3/DS3M supports four operational modes:
• Normal E3/DS3 tributary operation (as for DAC 3xE3/DS3)
• E13 multiplexer mode. One or two E3 interfaces are multiplexed to an NxE1
backplane.
• M13 multiplexer mode. One or two DS3 interfaces are multiplexed to an NxDS1
backplane.
• 34 Mbps transparent E3 mode for video (MPEG) transport. One or two transparent
E3 tributaries are each mapped to a 34xE1 backplane.
