Tl Trunk Card (Cti’d)
There are two situations for connecting a Tl to a the infinite DVX ill Digital System:
1.The fir#t and most prevalent situation is when a TlciIfiuitis provided by a carrier directly to the infinite
DVXDigital System. In this case the infinite DVXDigital System always receives clock
synchronization from the carrier and the receive clock recovery cable should be installed between the
Tl trunk card and the Voice Control Board (VCB).
Use the thin coax receive clock recovery cable to connect the SMB coax connector J2 (System 
SyncOut) on the 
Tl trunk card to J6 (Tl Clock) on the Voice Control Board (VCB). If more than one Tl
trunk card is to be installed, the receive clock recovery cables are chained between the cards and thento the VCB. Connect the J2 
(T7 clock auf) on the Tl trunk card furthest from the VCB to Jl ( T1 card
clock in) of the next Tl trunk card, and so on until a connection is made to the VCB. See Figure 4.
When the 
Tl trunk card is installed in a system with the power on, the red Test Mode LED (DS7)
flashes at a 
l/lCrth second rate. After a few seconds, the Receive Carrier Loss LED (DS2) lights and
stays on until the 
Tl span is connected and working.a
Below is the cable configuration for connecting the Tl trunk card when the Tl circuit is provided from the
carrier. This cable is provided in the 
Tl kit.

2.A second situation is when the Tl circuit is between two systems. In this situation, the receive clock
recovery cable is not connected to the Voice Control Board 
(VCB) at one of the systems. Connect the
receive clock recovery cable in the system that receives the source of timing. The system that provides
the most accurate timing should be the s
telephone system). With the infinite DVX
PHrce of timing (either from a carrier or internally in the
Digital System it is normally preferable to receive clocking
from another system, and therefore the coax cable should be connected to the VCB. Below is the
configuration for the cable to connect two systems together.

2. Program the Tl cicuit charnels (hss) ushg System Programming.
A Tl Tabk Programmhg:
The infinite DVX “IDigital Key Telephone system can be programmed to meet each customer’s individual
needs. All programming is done either at Station 100 using the 
33-button display ty[rinal as the programming
instrument or an ASCII terminal or PC. (For complete instructions see infinite DVXGeneral Description,
Maintenance and Installation Manual; Section 700.)
To enter the pgram mode:
a.Press ON/OFF button. (optional) LED lights and intercom dial tone is heard.
b.On the dial pad, press the asterisk (‘) twice.C.
On the dial pad, enter the digits [3][2][2][6] (DBAM)‘. Confirmation tone is heard:
d.The ON/OFF button LED is lit. The system is ready to program.‘-
l This is a default setting. However, it may be changed after entering programming.
To program the Sbt for the Tl trunk card:
1.Press Flash and dial [24] (Flexible Card Assignments) to program a slot for the Tl trunk card. The LCD
displays the following: (the current or default configuration of the Key Service Unit.
Where
- S= Station Board (KT12),
- C= CO Line Board or DID Board (C012/DID) ,
- #= Empty Slot,
2.Buttons l-1 8 on the digital terminal now indicate peripheral card slots l-l 8. When the Flexible Card
Assignments program is initially entered, Flex Button # 1 LED indicates that the user is programming
Peripheral card slot 1.
3.Press the appropriate flex button for the slot where the Tl trunk card has been inserted in the KSU
Cabinet.
In the following example, a 
Tl trunk card was installed in slots 5 and 7 so the LED button 7 was pressed and
becomes lit.

4.Enter the one-digit code- (Dial 4 for Tl) on the keypad to identify the card slot as having a Tl trunk
card installed. The ID’s for the Card assignments are as follows:
0 
= Key Telephone Board KT12
1 
= C012/DID (CO Loop Interface Board or Direct Inward Dial)
2 
= TIE Trunk (E&M)3 
= Combo 6 x 6

# = Delete Slot
5.Press the HOLD button to save the Tl configuration when finished. A confirmation tone is heard and
the LCD displays the updated information.
,
In this case the 5th and 7th slot have a “T” and the 6th and 8th slots shoti a vacant space because Tl
uses its assigned slot, and the slot to its left to control timing.

Tl Charnel Charactehstii:
Once the Tl is assigned to a slot, assign each Tl line (channel) or a range of lines individual characteristics.
There are two sets of assignments to the buttons in the FLASH 40 programming mode, Page A and Page B.
1.Press the FLASH button and dial [40]. The LCD displays the following:
2.Use the dial pad to enter a four-digit number for the range of Tl lines to program. The possible range
for these lines is 01-96. If only one line is programmed, enter that number twice.
Example:(0408) represents lines (channels) 4-8
(0101) represents line 1
3.Press the HOLD button, the confirmation tone is heard and the display now shows the following to
indicate the current configuration programming of that line or group of lines.
Where:
XX-XX 
= CO Line Range (01-96)C = DISA (trunk to trunk)FlXX = Flash Timer
DT = DTMF or Dial Pulse
P = Privacy Feature EnabledGRPX = CO Line Groups
CO = Line Type, CO or PBX
LSX = Loop SupervisionCOSX = Class of Service
UNA = Universal Night AnswerDSX 
= Type of DISA option

3.Mount the Charnel Service Unit (CSU) and corned &to the trunk card.
There are two Channel Service Unit (CSU) options that come with the Tl kit. Instructions are included for both
options. Use the set of instructions that applies to the kit that you received. Instructions for the Adtran 
CSU
start on page 30 of this document.
INSTALLING THE Kentrox CSU
The stand-alone Channel Service Unit (CSU) provided in the 
Tl kit can be mounted on a desk or on the wall.
Mounting brackets are provided. Before mounting the CSU, remove the stand-alone CSU card. Gently slide
the card out of the CSU Universal Mounting Shell. The card also needs to be removed if any of the options or
switches need to be changed.
\
Powerhg options
The CSU can be powered by simplex power drawn off the carrier line, or by a local pow&r source.
Once you have determined which power source to use, set the LINE POWER/LOCAL POWER JUMPER on the
CSU power board. One side of the jumper is labeled LOCAL the other side LINE. The unit is in Local power
mode when the LOCAL label faces the edge of the circuit board, and Line mode when the LINE label faces the
edge.
To change the jumper, remove it by gently prying up on it with a small screw driver, turn it so that the desired
power option faces the closest edge, line up the legs with the socket, and press down gently until it is firmly
seated.
On the rear of the CSU is a six-post terminal plug. The Pin assignments for this terminal plug are as follows:
Pin 1Battery Return (V+)Pin 2 No Connection
Pin 3 Battery (V-)Pin 4 Frame Ground
Pin 5 Alarm (Ring)
Pin 6 Alarm (Tip)
The CSU nominally requires 60 mA and must not exceed 150 mA, at 32 V.
