1 Preface
The documentation on hand is meant as a completion to the user manual of
the OPERA™ measurement system. This documentation describes the E1/T1
Option (OPR-002-E1T-P) for the OPERA™ voice quality analyzer. Before you
start reading this documentation, you should have studied the OPERA™ User
Manual thoroughly, since the basic operation of components of the OPERA™
system is assumed to be known in the following.
OPTICOM's E1/T1 interface option provides you with a large variety of
protocols. In the current version the following protocol types are available:
E1 Euro ISDN,
E1 MFC-R2 CAS protocol including many country-specific variants,
E1 CAS-R2 protocol including R2D and R2D modified variants,
T1 CAS/Robbed Bit protocols including E&M wink start, E&M
immediate start, E&M delay dial/start, loop start and ground start, and
T1 National ISDN-2 PRI protocol.
T1 ISDN implementations for particular switches are supported as
T1 ISDN PRI protocol for the Lucent®/AT&T® 4ESS switch,
T1 ISDN PRI protocol for the Lucent®/AT&T® 5ESS-9 switch,
T1 ISDN PRI protocol for the Lucent®/AT&T® 5ESS-10, and
T1 ISDN PRI protocol for the Nortel® DMS100 switch.
In addition, a number of transparent protocols are available that provide the
physical interface layer, without any signalling-related functions. The
protocol types including all parameter settings for the interface board are
fully software configurable.
With the E1/T1 Option for the OPERA™ voice quality analyzer, you may
modify the protocol parameters and even the entire state machine of T1
CAS, E1 MFC-R2 and E1 CAS-R2 protocols. You may also create your own
call progress tones configuration files if the files provided by OPTICOM
should not meet your requirements.
In Section 2 of this document you will find a description of the board
hardware. Section 3 provides information about the setup process of the
interface board parameters, an overview of the available parameters and
their meaning is given here. How to perform measurements with the E1/T1
interface is explained in Section 4, the new command line parameters for
automated measurements from script files are described in Section 5.
Measurement examples can be found in Section 6. Here, you will also find
example parameter settings for several protocol types.
