Operation
The DID/LT trunk card is software-controlled by the Main Controller. The DID/LT trunk card can
maintain voice and data communications through four trunks supported by the DID/LT trunk
card in both incoming and outgoing modes. For example, the DID/LT trunk card interfaces
incoming DID trunks from a CO, and incoming and outgoing trunks between co-related systems.
Any combination of these applications can be handled by the DID/LT trunk card.
DNI Line Card
The Digital Network Interface (DNI) Line Card provides 16 voice and data lines. The DNI line
card provides an interface for MITEL digital network devices including SUPERSET telephones,
and attendant consoles.
The DNI line card features devices that are compatible with MITEL SUPERSWITCH™ DIGITAL
NETWORK (MSDN) data transmission protocols. MSDN technology allows simultaneous
2-way transmission of digitized voice and data over a twisted copper pair. The DNI line card
supports voice/data transmission at the rate of 128 kb/s (64 kb/s on each of two voice channels)
and 16 kb/s on one signaling channel over a loop length of up to 1000 meters (using 24 - 26
AWG wire (25 - 27 IWG)).
