3DB 23063 ADAA - Rev 004 July 2007
• The nominal loss through each coupler is 3.5 dB, meaning an additional 7 dB
loss must be included in the system gain calculations for each link.
• All RAC 40 capacity options are supported for 2+2 protection: 64x, 75xE1,
70x, 84x, 100xDS1, or STM1/OC3.
• The example illustrates a repeater/aggregation Node with a 16xE1 drop. While
the up-haul capacity on the lower INUe may therefore only need to support
59xE1, because its co-channel partner is still transporting 75xE1 traffic, it must
also be over-air configured for 75xE1.
