Capacity Upgrade
When selecting capacities for individual RAC/ODUs, it is important to ensure
the maximum throughput capacity for a Node is not exceeded, and that the mix of
capacities is backplane compatible. Otherwise the requested upgrade will be
signalled as invalid. For instance, a 64xE1 selection for all six RAC/ODUs is
clearly in excess of the Node throughput capability.
Upgrading to Protection
When upgrading from non-protected to hot-standby or diversity operation, the
licensed capacity for the additional RAC/ODU must at least match the capacity
of its partner RAC/ODU.
Modulation
Modulation is not licensed, so can be selected in CT within each licensed
capacity, subject to the bandwidth options provided for the selected capacity. For
instance, a 20xE1 capacity selection has two modulation options: 16QAM or
QPSK.
IDU ES License
An IDU ES includes a base license for 50 Mbps data throughput. Higher
throughputs are obtained by ordering additional capacity upgrades at time of
order, or subsequently as downloadable software licenses.
• The base license is included with an IDU ES.
• A license is identified by the nominal Ethernet data capacity (throughput)
supported. In effect a license enables the number of E1 or DS1 link circuits
required to support the capacity.
• The licensed steps and associated capacities, modulation and channel
bandwidths are shown in Table 4-1 for ETSI, and in Table 4-2 for ANSI.
• For ETSI, capacity sub-options of 20, 30 or 40 Mbps are supported. All are
enabled within the base license.
• Licenses are up-to licences. For example ETSI IDU ES 100 may be configured
to support throughputs from 20 to 100 Mbps.
