Chapter 1. 9500 MXC System Overview
Vol. II-1-4
IDU 20x
Figure 1-2.
IDU 20x is capacity licensed. The base configuration supports 20xE1/28xDS1,
with higher capacities to 40xE1 or 32xDS1 obtained by requesting additional
capacity upgrades at time of order or as field-downloadable software licenses.
See IDU 20x License on page 4-4 of Volume IV.
Synchronous or asynchronous auxiliary data and alarm I/O options are included.
IDU 20x supports ODU 300ep or ODU 300hp.
IDU 155o
IDU 155o supports a single 155 Mbps STM1/OC3 tributary on optical SC
connectors. Modulations options are 16, 64 or 128 QAM.
IDU 155o
Figure 1-3.
IDUs are paired to support hot-standby or space diversity operation. Optical Y
cables provide a single Tx and Rx interface.
• Tx switching is not hitless.
• Rx switching (voting) is hitless (errorless).
Synchronous or asynchronous auxiliary data and alarm I/O options are included.
Supports ODU 300ep or ODU 300hp.
IDU ES
IDU ES supports Fast Ethernet to 200 Mbps to provide an uncomplicated and
cost effective alternative to fiber. Its Layer 2 switch supports four customer 10/
100base-T ports, two over-air transport channels and comprehensive VLAN and
QoS options.
Data throughputs range from 20 to 200 Mbps, and depending on throughput
channel bandwidth ranges from 7 to 56 MHz, with modulation options from 16 to
128 QAM.
Link capacity may be fully assigned to Ethernet traffic, or between Ethernet and
up to 8 wayside E1/DS1 circuits.
Capacity is licensed. The base configuration supports 50 Mbps data throughputs,
with higher capacities to 200 Mbps obtained by requesting additional capacity
upgrades at time of order or as field-downloadable software licenses.
