Voice card installation and wiring
Different cabling and wiring setups are required for voice cards compatible
with the TDM Recorder. The following sections show compatible Ai-Logix
voice cards, their installation, and typical wiring requirements for digital
trunk-side (DP models), digital station-side (NGX models), and analog
station-side (LD models).
Before setting up the wiring, a site survey must be conducted to clarify cable
requirements and equipment location. Additionally, computers must be
checked to ensure that they can accommodate full length PCI cards.
Note: A Customer Supplied Unit (CSU/DSU) may be required between the
PBX and the card.
