Scrambler
Only applicable when using the GFP data link protocol. Tick this box to enable the module
internal scrambler. Must be ticked to successfully receive scrambled network data.
GFP keep alive
If enabled, sends 2-3 keep alive messages per second. Enable this parameter if Loss of
Frame (LOF) indication is frequently encountered. Generally relevant to older equipment
types. Only applicable when using the GFP data link protocol in a T3 interface.
Ethernet flow control
A tick enables flow control of Ethernet data from the CP525 to the SFP module. Flow
control prevents data overflow in the SFP module buffer. Buffer overflow leads to data loss
that would go unnoticed until attempting to decode the data at the receiving end.
In the Fault Propagation field check boxes allow to select which TDM network fault(s) shall
cause shut-down of the ethernet data flow:
LOS
Loss of signal
AIS
Alarm indication signal
RDI
Remote defect indication
LOF
Loss of frame
FEAC
Far end alarm and control
Whether or not RDI , LOF and FEAC are applicable depends on Interface type , Module protocol
and Line type settings.
In the
Loss of Signal Behaviour
field check boxes allow selecting which TDM condition shall
send an LOS indication to the Ethernet interface:
LOS
Loss of signal
LOC
Receive loss of lock
AIS
Alarm indication signal
RDI
Remote defect indication
The Taffic Queues field allows mapping of network traffic queues to VLAN priorities. For
information on VLAN priority usage refer [7] .
