SYSTEM OUTLINE
The Data Interface can provide the intra- or inter-office digital data transmission on fixed path
(Nailed-Down) connection. The Data Interface equips the V.11 (X.21) and the V.24/V.28
(RS-232C) interface. When you use the V.11 (X.21) interface, a maximum of 64 kbps digital data
transmission is available. When you use the V.24/V.28 (RS-232C) interface, a maximum of 19.2...

When the PBX is an end office in the Inter-Office Digital Data Transmission through Nailed-Down
Connection, the digital signal is transmitted directly. A maximum of 64 kbps digital data
transmission is available for the direct digital transmission.
When the PBX is a tandem office in the Inter-Office Digital Data Transmission through Nailed-
Down Connection, data transparency is...

DPC
The Data Port Controller (DPC) can accommodate a maximum of two DTE per cards with V.11
(X.21) or V.24/V.28 (RS-232C) interface, and can provide the intra-office or inter-office digital
data transmission on Nailed-Down connection.
DTI
The Digital Trunk Interface (DTI) interfaces the PBX directly to a 24/30-channel PCM
transmission line. The DTI has the following functions.
For...

System Outline
PLO
The Phase Locked Oscillator (PLO) equipped on the MP card synchronizes the system to the
digital network clock.
When the PBX is a clock receiver office, the PLO generates the clock signals according to the
source clocks received from the source office within the network. The source clock signals are
extracted at DTI cards and supplied to the PLO. Two clock routes are available; one...
