Configure DT voice cards

The following sections describe how to modify properties and channels in the digital terminate (DT) voice card family (which supports the PCM30 type protocol and Active Recording on T1 & E1 mode).

The DT card is trunk-based and can be used in trading environments such as stocks, bonds and commodity trading (apart from active recording support). The DT card is cabled over twisted pair cable and terminated with RJ-45 connectors. The card supports 24 and 30 voice channels per T1 or E1 trunk span respectively.
