4 Signal Acquisition Using OptiCall™

This section provides a short description of how to use the OptiCall™
application to perform measurements using the E1/T1 interfaces. For a more
detailed explanation, please refer to Section 4.2.3 (page 39) in the OPERA™
User Manual Version 3.0.
If you are already familiar with using OptiCall™ with POTS telephony or
audio interfaces, you will not face any need for reorientation when
performing measurements with the E1/T1 interface option. There are only a
few things you need to notice which are explained in the following.
Figure 4.1: The OptiCall™ dialog showing selected E1 MFC-R2 interface devices.
As shown in the example screen shot of OptiCall™ in Figure 4.1, the
protocol type you have selected within OptiConf™ (see Section 3.2), is
shown as a part of the device name in the list box for the origin and
termination device, respectively. The protocol name is then followed by the
port number that represents the index of a trunk of the E1/T1 interface board.
For instance, "Port 0" represents the first trunk.
Each E1/T1 device name is terminated by the B-channel notation – e.g. "BCh
0" would represent the first valid voice bearing channel of a particular trunk.
Please note, that only those channels of a trunk are registered in the device
list that may carry voice information. That is, the D-channel of an ISDN
configured trunk will not be found in the device list of OptiCall™, for
instance. Consequently, all E1/T1 entries found in the list boxes of OptiCall™
may be used for measuring. The numbering of those channels starts with
zero.
