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) interfa ce. When you use the V. 11 (X.21) interfa ce, a maximum of 64 kbps di gital data
transmission is avail able. Whe n you use the V.2 4/V.28 (R S-232C) interf ace, a maximum o f 19.2
kbps digital data transmission is available.
To add the V.11 (X.21) or V.24/V.28 (RS-232C) Data Interface to the system, it is necessary to
install the Data Port Controller (DPC) card. You can provide the V.35 interface DTE by the M03
card installed in addition to t he DPC card. The M03 card converts the V.11 (X.21) interface to a
V.35 interface. When you provide the inter-office digital data transmission, it is necessary to
install the 24/30-channel Digital Trunk Interface (DTI) card in addition to the DPC card.
Figure 1-1 and Figure 1-2 show the outline of the Data Interface intra-office/inter-office
connection.

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) in terface, and can pro vide the intra-offic e 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 24DTI:
• Unipolar/Bipolar Conversion (AMI Format)
• Signaling Insertion/Extraction
• Alarm Detection/Insertion
• Digital PAD on Voice Signal Transmission
• Loopback Test (Local/Remote Loopback)
• Cyclic Redundancy Checking (based on ITU-T Rec. G704)
For 30DTI:
• Unipolar/Bipolar Conversi on (HDB3 Format)
• Signaling Insertion/Extraction
• Alarm Detection/Insertion
• Digital PAD on Voice Signal Transmission
• Cyclic Redundancy Checking (based on ITU-T Rec. G704)
• Channel Associated Signaling (based on ITU-T Rec. 0421 Digital R2 Signaling Code)
For connection of a 24 DTI and transmission line, t wisted-pair cables can be used. Fo r connection
of a 30DTI and transmission line, either coaxial cable or twisted pair cable can be used.
M03
The M03 provides V.35 Data Terminal Equipment interface.
M03 is connected to the DPC and converts V.11 (X.21) interface to V.35 interface.

CHAPTER 1 GENERAL INFORMATION
System Outline
PLO
The Phase Locked Oscillator (PLO) equipp ed 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 card s and supplie d to the PLO. Two clock routes ar e available; o ne is the R oute
0 from the sour ce o ffi ce , an d t he other i s a st andb y Rou t e 1 from a sub-source office. When no
clock signals arrive from the sou rce and sub-source office, due t o a transmission line failure, the
PLO keeps generating the clock si gnals at th e freq uency of th e previo us source clock. The PL O
can receive different frequency of source clocks from the Route 0 and Route 1.
Figure 1-3 shows an example of the clock supply route when the system is a receiver office.

As shown in Figure 1-4, the 30DTI card uses the time slot on the basic Highway 4.
Therefore, the total number of time slots for all 30DTI card must be 128 time slots or less
including all other application processor cards which use the Highway 4.
The 24DTI card can use the time slot on both the basic and expanded Highway 4 and 6.
Therefore, the total number of time slots for all 24DTI card must be 256 time slots or less.

CHAPTER 1 GENERAL INFORMATION
System Conditions
Time Slot Allocation for DTI Card
On each DTI card, the system recognizes the lowe st and highest channel numbers to which trunk
numbers have been assigned, and allocates time slots to all the channels within them. If trunk
numbers are assigned to discontinuous channels in this case, the system also allocates time
slots to channels not assigned.
For example, as shown in Figure 1-5, even wh en Channel 1 through Channel 1 0 have been
assigned by the system data programming (CM07 YY=01) except Channel 5, the system
allocates a total of 10 time slots for all the ten channels. Therefore, to avoid allocation of
unnecessary time slot s, it is recom mended tha t consecuti ve channe ls are a ssigned on each DTI
card.

Conditions on Connecting DTE
Forcible ON control of DTR, RTS/C signal:
When connecting the DTE which does not support the DTR signal and RTS/C signal, these
signals can be turned to ON forcibly by switch setting on the DPC card.
Condition of CTS signal ON control:
The CTS signal is turned to ON afte r 60 ms fro m the time when rece iving the RTS/C sig nal. And
the CTS signal is turned to ON under the following conditions.
1. The DTR signal is ON.
2. The received X signal is ON (The synchronization of the opposite office is established).
3. The sending X signal is ON (The synchronization of the PBX i s est abli shed).
Limitation on usin g mod em :
When using modem, the DTR sign al from the DTE can not be transmitted to the PBX (DPC card).
Therefore, the DTE starting by the DTR signal can not be used.
