Installation Dragon PTN Nodes
Release 01 02/2018
2.4
CSM (=Central Switching Module)
2.4.1
General
The XT-2210-A/XT-2209-A/XT-2206-A node can host two redundant CSMs, the XT-1104-A
node can host one. The CSM is the heart of the node and controls communication between
the different interface modules. It also provides the interface to HiProvision (=Dragon PTN
Management System).
The node or the CSM itself exchanges services data (Ethernet, MPLS-TP, E1/T1, SHDSL…)
with the outside world via the interface modules that are plugged into the Dragon PTN node.
This means that a Dragon PTN node only communicates with other Dragon PTN nodes via its
interface modules, not via the CSM itself.
The only data that enters/leaves the front panel of the CSM is the management data to
HiProvision.
2.4.2
CSM Redundancy
CSM Redundancy means that two CSMs are installed in the node. One CSM will be the active
one while the other CSM will be the standby one.
CSM Redundancy provides a higher availability of the services through a node if a CSM
should fail. If one fails, the redundant hot-standby CSM will take over automatically to the
keep the node and all its services alive (with a minimal service interrupt).
A manual switchover is also possible via the NSM, CSM or HiProvision.
For more information, see Ref. [3] in Table 1.
2.5
IFM (=Interface Module)
All peripherals are connected to the Dragon PTN Network via IFMs, which are available for a
wide range of applications in the areas of data and LAN.
Each
IFM
has
its
own
manual,
which
can
be
found
on
the
Portal
(=
https://hiprovision.hirschmann.com
)
via Shortcuts
à
Manuals.
Dragon PTN nodes can provide slots for up to ten IFMs. Both low speed (1G) and high speed
(10G) IFMs can be used together in the same node. The slot into which the IFM can be
plugged depends on the IFM speed type (1G, 4x1G or 10G) and the node type slot speeds.
Always verify the IFM manual for more information on the slots into which it can be plugged.
