3 Setup of the E1/T1 Board Parameters
Before you will be able to start performing measurements with the E1/T1
interface board, the board's configuration parameters will have to be set up.
These parameters affect the board's operation. For instance, the protocol
type that is being used is defined at this point.
After the user has finished setting all necessary parameter values, the
initialization process is started during which the configuration parameter set
is downloaded via the computer host's PCI bus to the E1/T1 interface board.
Note:
The board configuration parameters are not "on-the-fly-
changeable" in the sense that changes will only take effect
after the consecutive initialization process.
Please note, that after the start-up of the OPERA™ host PC, the last chosen
parameter configuration set of the E1/T1 board is immediately available. If
this configuration meets your requirements, you may directly start the
OptiCall™ application in order to perform measurements. For a description
of the OptiCall™ application, please refer to Section 4.

Configuration Parameters Overview
In this section an overview of the available configuration parameters and
their meaning is given. Only those parameters are described that will have to
be set up by the user.
3.1.1 Protocols
The E1/T1 Option for OPERA™ offers a large variety of protocol types which
are listed and described in the following.
E1 Euro-ISDN
– ISDN PRI Pan-European (CTR4) protocol with many
information elements and call control messages.
- Common E1 MFC-R2 CAS protocols including line signalling
E1 MFC-R2
and compelled register signalling. National variants such as for China, Israel,
Mexico, Philippines and more are available. You may change the protocol
parameters and even the entire state machine by editing the protocol textual
table that is downloaded to the E1/T1 interface board after the setup of the
configuration parameters will have been finished. For a description of how
to edit a CAS protocol table, please refer to Section 7.1.
- Common E1 CAS protocols including line signalling and
E1 CAS-R2
MF/DTMF address transfer. Available are R2D and R2D modified variants.
You may change the protocol parameters and the state machine by editing
the protocol textual table. For a description of how to edit a CAS protocol
table, please refer to Section 7.1.
