Reviewing The Voice Channel Card
The voice channel card (Figure 6-2) is designed with
four digital recording and playback channels. Each
channel includes circuitry that directly interfaces with
a DXP digital station port. The DVA can hold a
maximum of four voice channel cards. Since each
voice channel card provides four voice channels, the
system capacity is a maximum of 16 voice channels.
The voice channel card connects to the I/O Board
through a voice channel ribbon cable. You must
connect all four voice channels to station ports from
the same DXP station board, and you must connect
them in sequence. This means that you can not skip a
channel. If you need to add or replace a voice channel
card, you must turn the power off while you make the
installation.
By changing the card select jumper J2 and J3 (Figure
6-3), you can select the different voice channels (see
Table 6-1 for details).
Example: If you set the jumpers for CARD 0, the first
of four voice channels becomes Voice Channel 1.
This corresponds to voice channel 1 on the I/O Board.
If you set the jumpers for CARD 2, the first of four
voice channels becomes Voice Channel 9 on the I/O
Board.
