Connection via ECC8) (optional)
An alternative option, which permits the management channel to be routed
in the XMP1 network, is the use of ECC8 with a data rate of 8 kbit/s. In this
case, the management information is transmitted in time slot 0 of the PCM
frame (E1) in bits 7 and 8. This must be taken into consideration during
network planning with regard to the expected performance.
The node number and SISA node number must be identical in this case.
For performance reasons, each sub-network connected via ECC8 should
not include more than 30 nodes. The range of numbers used as node
numbers and SISA node numbers is 1....254 for these nodes.
Note: For performance reasons, an SDH node should always be
connected over IP.
The access node must not include a service channel (DK) routed via RS232
if it shall be connected to SOA over IP. This access node must only be
connected over IP. If the SOX network management system shall be
connected to the RS232 interface, the setup of a service channel via RS232
must be prevented. For this purpose, in the card-specific settings of the
Central Unit, Switch 2 (QD2 Adapter Simulation) must be set. This setting
can be made by means of the LSP or SOX MSP.
The schematic diagram depicted below shows an example of such an
application.
In this example, node 3 is the access node to SOA and is configured as
ECC8 Master. SISA-V of node 3 communicates with the SOA SISA-I. This
configuration is performed via the decentral card slot data of the Central
Unit - info no. xx "ECC8".
In addition, the IP address of the computer running the SISA-I process,
must be configured via menu item 75 "E.Addr.SISA-I Addr" of the ABM. The
SISA-I access number is configured via menu item 76 "E.SISA-Conn. No.".
If the node is configured as ECC8 Master, a SISA-V (4) appears underneath
the SISA-V. This indicates that ECC8 is used as management channel. In
this case, the management information is transmitted via this SISA-V (4) to
the SISA-V from where it is passed on to SISA-I.
