DAC
DACs provide the intermediary between customer interfaces and the digital
backplane.
• Different DACs support different circuit rates and formats. Refer to:
• DAC 4x on page 3-33
• DAC 16x on page 3-34
• DAC 3xE3/DS3M on page 3-35
• DAC 1x155o and DAC 2x155o on page 3-38
• DAC 155oM on page 3-40
• DAC 2x155e on page 3-43
• DAC ES on page 3-45
• DAC GE on page 3-53
• DACs can be installed in any of the universal slots in an INU or INUe, and in
restricted slots in the INUe.
• DACs are field replaceable and hot-swappable.
• Most DACs can be protected. The protectable DACs are DAC 3xE3/DS3M,
DAC 1x155o, DAC 2x155o, DAC 155oM, DAC 2x155e. Not protectable are
DAC 4x, DAC 16x and the Ethernet DACs. For information on DAC
protection, refer to:
• DAC/Tributary Protection on page 3-92
• Tributary Protection, Volume IV, Chapter 7.
• Node Protection Configuration, Volume IV, Chapter 8.
• For data on trib cable wiring and connector pin-outs, refer to Appendix C.
• For information on DAC loopbacks refer to Loopback Points in Volume IV,
Chapter 15.
• For information on the integrated PRBS generator and BER test function refer
to PRBS Generation in Volume IV, Chapter 15.
• For information on auto AIS/PRBS15 insertion in LOS (loss of signal)
conditions, refer to Auto Insertion of AIS or PRBS on Tribs, Volume IV,
Chapter 15.
