E1/T1 (Trunk/ISDN/QSIG/SS7) & ISDN-BRI Interface Specifications
- DATA LINK
Emulation mode: Behaviour on DL selected from a list:-
Channel specification: The TS allotment for DL can be automatic
or manual. The automatic mode has priority over the manual mode.
- Selecting IE configuration: The
number of the TS to be alloted to DL in monitoring mode is automatically
determined from the monitoring on SL of the signalling sequence.
The monitoring of a precise IE configuration can allow you to determine:
- The Call Reference of the first matching message.
- The TS value used in the call signalling message sequence resulting
in the start of the DL analysis for this channel.
- The clearing of the communication which switches off the analysis.
- TD time-slot(s) Selection
of one data channel (1 - 24/31 aggregated TS) in the TRANSMIT direction,
which is alloted to DL.
- RD time-slot(s) Selection
of one data channel (1 - 24/31 aggregated TS) in the RECEIVE direction,
which is alloted to DL.
Data link type: Structure of data used to record the events
monitored on DL.
In simulation mode, data type or data source used on DL.

File: For Byte-TS /Wav
data source type, a complementary selection area must be accessed.
Analysis mode: Recording of the data on DL.
- All: The event data on DL are recorded.
- Length: The event data on DL are partially recorded
and truncated beyond a maximum length which can be edited.
56K rate adaption:
 No:
The selected TS's are used as 64Kbits data channels. Yes:
The selected TS's are used as 56Kbits data channels.
Inverted polarity
- No:
The selected TS's are used in normal polarity.
- Yes:
The selected TS's are used in inverted polarity.
NRZI data encoding
- No:
NRZ data coding type at the physical layer.
- Yes:
NRZI data coding type at the physical layer.
