Status Page
Picture 13.
Commander’s “Status” page view.
The Status Page lists information messages about the
Decoder’s present status. The EASITM Configurer divides these
messages into three different categories according to severity
and uses Status Flags to make them more noticeable:
- Alarm messages are indicated with red flag.
- Warning messages are indicated with yellow flag.
- Notifications are indicated with green flag.
Status Flags and the corresponding text labels appears in the
Status field. A short description of the event can be read in the
Description field.You can also hide warnings and/or
notifications by ticking the corresponding checkboxes. Alarms
cannot be hidden. The “Apply” command is not needed to
verify these commands.
IND2x2 Series User Manual rev001 13

Messages are divided into four groups:
- Alarms concerning BIOS.
- Alarms concerning application.
- Warnings concerning application.
- Notifications concerning application.
Alarm
In case the unit senses an alarm a red Alarm flag appears in
the Commander’s Element Directory Window. The
description of this alarm can be read from the Commander’s
Status Page. At the same time a green “M” led indicator in the
unit’s front panel turns to yellow.
Warning
Usually a yellow Warning flag in the Commander’s Element
Directory Window indicates that there is something wrong
with the configuration.
Notification
A Notification flags in the Commander’s Status Page indicates
informative value only.

Properties Page
Picture 14.
Commander’s “Properties” page view.
The Properties page displays information of the unit’s
hardware and software.The unit’s name which you can see on
the Element Tree Window and Element Window can be set
on this page.
IND2x2 Series User Manual rev001 15

ATM Page
Picture 15.
Commander’s “ATM” page view.
The ATM page displays ATM/SDH (Asychronous Transfer
Mode / Synchronous Digital Hierarchy) connection status and
allows you to set all necessary VPI’s and VCI’s. VPI is the
Virtual Path Identifier. VCI is the Virtual Channel Identifier. VPI
is selectable between 1…255 and VCI between 1…65500.
These values compose a pair and it is not allowed to have two
similar identifier pairs for different streams in one network.
Transport stream frame
In this frame you can set the received video & audio signals.
Transport stream is the MPEG-2 compressed bitstream that
consists of video & audio.
Return audio frame
This is the dual audio channel digitized and sent by Decoder
(not compressed, sampling frequency 35.2 Mhz).You can
enable the return channel by ticking the appropriate checkbox.
Resolution window is used to minimize the required audio
bandwidth over ATM network. Normal setting is 16 bit with
around 1.1 Mbps bandwidth. Selecting 14 bit reduces the ATM
bandwidth around 200 kbit/s.
Data channel frames 1…4
The four RS data channels are all individual and can be routed
independently through the ATM network.
16 IND2x2 Series User Manual rev001

Loopback enable checkbox
When this box is ticked all incoming ATM cells are forwarded to
the next device in the network. Even those cells received by
the Decoder itself are copied forward. This allows Decoder
daisy-chaining and full utilisation of STM-1 capacity.
TS Filter checkbox
Because of the ability to loop forward the ATM stream it is
possible that the cells once sent are returning back to the
transmitting unit. In order to prevent those cells to start another
round in the network they are discarded. This box is a reminder
of the automatic cell deleting that takes place in every
Decoder. This feature is not user controllable.
Data Filter checkboxes
When theses boxes are ticked the bidirectional data channels
are not forwarded at the ATM level. If this box is clear the data
channels are considered to be broadcast type and they are not
only picked up by this unit but also are passed forward to the
next device in the ATM network. When using data broadcasting
and there are more than one terminal unit connected please
note that only one of them is allowed to answer at a time.
Multiple answers will cause a conflict at the master device of
the RS data network.
Stream Rate frame
This frame indicates the transmitted and received ATM bitrate
in kbps.
AU-4 Pointer checkbox
For SDH network operation the AU-4 pointer can be enabled or
disabled. The default setting is disabled (Sonet operation).
SDH frame
This frame displays the following flags:
LOS = Loss of Signal
The LOS alarm indicates that there are no transitions occurring
in the signal received by the network element.
LOF = Loss of Frame
The receiver raises the LOF alarm when an OOF condition
persists for 3 ms or longer. It clears the alarm when it receives
a valid signal for 3 ms.
IND2x2 Series User Manual rev001 17

OOF = Out of Frame
An OOF alarm occurs when one or more bit errors in each
framing pattern are detected for four consecutive frames.
LOP = Loss of Pointer
A network element transmits a LOP alarm downstream when it
receives 8 consecutive frames containing an invalid pointer, or
8 consecutive New Data Flags (NDF’s other than in a
concatenation indicator ).
AIS-L = Alarm Indication Signal-Line
RDI-L = Remote Defect Indicator-Line
AIS-P = Alarm Indication Signal-Path
RDI-P = Remote Defect Indicator-Path
Alarm Indication Signals and Remote Defect Indicators are
mechanisms used to report network faults.
Clock Rec.
This flag indicates if the clock recovered from the incoming
stream is close enough to the frequency of the reference
oscillator.
All changes in settings should be confirmed by
pressing Apply .
