This card is a eight circuit analog station interface for industry standard single line telephones or other analog peripheral devices. The 8SLI does not contain any over-voltage protection and is not qualified as OPX. This card automatically detects DTMF or dial pulse signals from the SLT ports. Each port on this card has built-in DTMF receivers (for DTMF tone detections from analog devices) and CID transmitters (sends FSK signals for displaying CID name and number to analog devices). The 8SLI3 does not need to share these system resources. This will relieve the congestion of the MFM, RCM2, or CRM system resources. It can be inserted in any universal card slot in all cabinets. Each port on this card is intended for connection to one telephone. Connecting multiple telephones to a port may result in incorrect operation or damage to the card. The 8SLI3 supports message waiting lamp functionality for analog stations that have this capability. This card supports Power Fail Transfer feature.
This card requires software version 4.60 or higher.
