RAC
Radio Access Card
An INU may be populated with a maximum of three RACs, and the INUe up
to six. Each RAC interfaces to a companion ODU via a single 50-ohm coaxial
cable.
• RAC 30 interfaces to ODU 300/hp/ep for channel bandwidths to 28/30 MHz
and capacities of 4xE1 to 75xE1, 4xDS1 to 100xDS1, 1xE3 to 4xE3, 1xDS3
to 3xDS3, or 1xSTM1/OC3.
• RAC 3X interfaces to ODU 300 for channel bandwidths 28/30 MHz to 50/
56 MHz and capacity options of:
• 64/75/93/100xE1
• 32/70/84/100xDS1
• 4xDS3
• 1/2xSTM1/OC3
• RAC 40 interfaces with ODU 300hp/ep for co-channel XPIC operation on
a channel bandwidth of 28 MHz (ETSI) or 30 MHz (ANSI), for capacities:
• 64/75xE1
• 70/84/100xDS1
• 1xSTM1/OC3
DAC
Digital Access Card
DACs provide customer line interface options for E1, E3, DS1, DS3,
STM1/OC3, or Ethernet:
• DAC 4x supports up to 4xE1 or DS1 tributaries.
• DAC 16x supports up to 16xE1 or DS1 tributaries.
• DAC 3xE3/DS3M supports three E3/DS3 tributaries, 2xE13 or 2xM13
multiplexer trib connections, or 2x34 Mbps E3 transparent mode
connections.
• DAC 1x155o supports one STM1/OC3 optical tributary.
• DAC 2x155o supports two STM1/OC3 optical tributaries.
