Description
Speed
The configurable parameters for the OC-3/STM-1 Trunk Module are:
Parameter name
Suppress Alarms
The Advanced parameters:
Parameter name
Transmit sync source
H1 SS bits
Signal failure filter period
The Alarms parameters are presented at the bottom of the table as:
Parameter name
Unequipped (UNEQ)
Los of signal (LOS)
Los of frame (LOF)
Los of pointer (LOP)
Alarm indication signal, line
(AIS-L)
Description
The interface id, 8b10b or Sonet/sdh. Written
as "nameX:Y" Where X is position of the card
and Y position of the port.
The operational status of the board.
The number of slots available for
transmission on this interface.
The capacity.
Description
When the service is up and running as
intended, enable the alarms for the service by
uncheck the Suppress alarms for;
All: When marked, all alarms are suppressed.
AIS: Alarm indication signal.
RDI: Remote defect indicator.
Default is that the alarms are suppressed.
I.e. you must uncheck the boxes to receive
the alarms!
Description
Selects whether to retrieve the transmitting
bit-clock for the interface from local oscillator
(interface) or from the bit clock received from
the remote node (loop). This shouldn't be
confused with the 8 kHz frame clock.
Differences between Sonet and SDH.
Sets value of the SS bits in the H1 byte in the
Sonet/SDH section overhead. Older
Sonet/SDH equipment may require other
value than the default.
00 Sonet
10 SDH
Delay time for 1+1. The time that the nodes
waits for underlying network
(SDH/SONET/WDM) to re-establish
connection. In order to avoid a switch over.
This parameter can also be used to allow
certain amount of errors without tearing down
channels or a certain trunk.
Description
Unequipped, signal for no service configured.
Loss of signal. No signal detected on
SONET/SDH network interface, no light in the
fiber.
Loss of frame. Unable to align SONET/SDH
frame, no light in the fiber.
Loss of pointer
No pointer for where payload is.
Alarm indication signal, line, defect detected
by upstream SONET/SDH network interface.
