DN081A 8-port and 161A 16- port Analog Interface Boards The DN081A and DN161A provides access to analog telephone lines for computer telephony systems based on the industry standard CT Bus. With M2T modules, DN081A or DN161A provides up to 8 or 16 independent analog loop start interface circuits respectively. Without M2T, they are used as resource boards. Voice-band signals are digitized and passed in real time between the analog telephone network and the CT Bus. Features and Benefits DN081A(8 ports) and DN161A(16 ports) enable high-density applications. Distributed CT Bus switching permits inbound/outbound call re-routing, both inter-board as well as intra-board. Signaling functions such as loop seizure, current detection, and ring are controlled and monitored through the host-PC interface Toll quality voice encoding and decoding Support for Caller ID calling party number retrieval Transient protection circuitry for high reliability DN Series board’s voice format fully compatible with Intel Dialogic’s voice format. Provides variable voice coding at 24/32 Kb/s ADPCM(.vox), 48/64 Kb/s A-law/u-law PCM, and 48/64 Kb/s A-law/u-law/linear waves. H.100 connector allows for easy future expansion to the industry-standard CT Bus. Configure multiple boards in a single chassis, PCI bus, for easy and cost-effective system expansion of up to 128/256 analog ports Supply the same API as D/160SC-LS,D/41ESC, D/41EPCI,D/41H of Intel Dialogic(SR5.11).
