Table 205 System Status attributes – TDM
Attribute Meaning
TDM Interface
Control The type of TDM interface that is activated (None, E1 or T1). This is set
on the Interface Configuration page.
TDM Interface
Status The current status of the Ethernet link between the NIDU (ODU port) and
the ODU (PSU port) (OK or Not Connected).
•
Green “
OK
”: The Ethernet link is established.
•
Red “
Not Connected
”: The Ethernet link is not established.
TDM Single Payload
Lock The current status of the single payload locking feature:
•
“
Enabled
”: The ODU will prevent transition from Single Payload
modes to the higher Dual Payload modes. The ODU applies this lock
when it calculates that such a transition would pass through modes
which cannot carry telecoms data.
•
“
Applied
”: The ODU is actively preventing these transitions.
•
“
Disabled
”: The wireless will transition to the faster Dual Payload
modes as soon as the conditions are appropriate.
TDM Latency The end-to-end latency of the TDM service between TDM ports at the
NIDUs (μs).
TDM Channel
Status n The current status of the TDM service between NIDU port "n" at the local
NIDU and the corresponding port at the remote NIDU. For a list of values
and their meanings, see
Table 206 .
Table 206 TDM Channel Status values and meanings
Value Meaning
Up TDM data is being bridged between the TDM ports on local and
remote NIDUs (green background).
No Signal (Local) No TDM data is being received at the TDM port on the local NIDU.
No Signal (Remote) No TDM data is being received at the corresponding TDM port on
the remote NIDU.
No Signal (Local and
Remote) No TDM data is being received at the associated TDM ports on
local and remote NIDUs.
No Signal (Local and
Remote Timing) No TDM data is being received at the TDM port on the local NIDU.
TDM data is being received at the TDM port on the remote NIDU.
The modulation mode of the link is too low to support bridging of
TDM data in the remote to local direction, but the transmit clock at
TDM port of the local NIDU is synchronised to the clock received at
the TDM port on the remote NIDU.
