Chapter 3. 9500 MXC Nodes
Vol. II-3-6 Alcatel-Lucent
Capacity and Bandwidth: PDH and SDH
The 9500 MXC INU and INUe provide configurable link (over-air) capacity and
bandwidth options up to 100xE1

, 127xDS1, 4xDS3, 2xSTM1/OC3.
Figure 3-4 shows the capacity migration options and in particular the broad
coverage provided by ODU 300 and RAC 30v3/3X combinations. Table 3-1 on
page 3-5 shows the capacity steps.
Node capacity licensing is introduced on page 13.

ODU 300 with RAC 40
RAC 40 supports Co-channel, Dual Polarized (CCDP) operation using a built-in
Cross-polarized Interference Cancellation (XPIC) function. Two links are
operated on the same radio channel, with one using the vertical polarization, the
other the horizontal.
RAC 40 operates with ODU 300hp or ODU 300ep.
RAC 40 supports:
• Two 64xE1, 75xE1, or STM1 links on one 28 MHz channel.
• Two 70xDS1, 84xDS1, 100xDS1 or OC3 links on one 30 MHz channel.
Figure 3-5 illustrates the capacity and bandwidth options.

To achieve a 100xE1 link capacity the RAC 3X 106xE1 capacity option (modem profile) is used, but a
maximum 100xE1 circuits are accessible on the backplane. The 106xE1 modem profile is used to support
INU to IDU ES link compatibility.
