Figure 5-13 E1 Direct Card Properties Clock Recovery
The data clock may be generated by the E-QUE card (Local Generated) or taken from the
E1 line. The clock source must be determined before configuration. Select the correct
configuration by clicking on the appropriate radio button.
5.26.5 Codec
E-QUE cards configured as E1 Direct use two cables plugged into ports 1 (top) and 5
(bottom) for the E-QUE card to provide E1 ports. The top cable (Top Half) provides the first
30 ports (1-30) and the bottom cable (Bottom Half) provides the second 30 ports (31 - 60).
The top and bottom cables can be configured to use different Codecs. The Codecs
available are:
G722 - standard G722 conversion and compression.
G722 A-Law - uses an A-law algorithm to optimize the G722 codec. This is often
used in European systems.
G722 µ-Law - uses a µ-law algorithm to optimize the G722 codec. This is often
used in North America and Japan.
Click on the appropriate radio button to select the codec for top and bottom cables.
