Voice Trunk Line Part
The voice trunk line part is configured with digital trunk lines and analog trunk lines.
The TEPRIa interfaces with the E1, T1, or PRI digital trunk lines and send/receive voice
data through the trunk lines. They transmit the voice data of 64 Kbps per channel. 8 TRK
(8Trunk) provides the Caller ID (CID) Path function basically and provides the Polarity
Reverse Signal (PRS) and Metering Pulse Detection (MPD) function as options. 8 TRK
transmits/receives voice by the analog office line, and transmits 64 Kbps data information
per a channel. 8 TRK2/16TRK (8Trunk2/16Trunk) provides the Caller ID (CID) Path
function basically and provides the Polarity Reverse Signal (PRS) and not provides
Metering Pulse Detection (MPD) function .If option board 4TRM is mounted on the UNI
board, it operates as a voice trunk board and supports an analog trunk line, and provides the
CID & PRS.
Voice Station Part
The voice station part is configured with a Digital Line Interface (DLI), which interfaces
digital voice stations, and Subscriber Line Interface (SLI), which interfaces analog voice
stations. Multiple DLI and SLI boards can be mounted on any slots of the main or
expansion cabinet depending on the numbers of analog/digital voice stations. 16DLI,
16DLI2 and 8DLI are Digital Line interface boards. 16SLI, 16SLI2, 16MWSLI, 8SLI and
8SLI2 are analog Subscriber Line interface boards. In addition, the hybrid-type 8HYB,
8COMBO, and 8COMBO2, which contains interface circuits for analog and digital stations,
exists.
UNI equipped with 4SLM and 4DLM operates as a voice station board.
