B. CONNECTING Tl SPANS TO TEE MDF 
5.8 The installation procedure used to connect Tl 
spans at the MDF is dependent on the type of termina- 
tion used by the telephone company and how close it is 
to the MDF. The Tl spans may be terminated on RJ48C 
modular jacks or on RJ-type terminal blocks. 
5.9 Follow one of the three Tl termination methods 
(A, B, or C) outlined on the following pages. 
NOTE: The Tl span is typically connected to the stan- 
dard RJ48C jack provided on the Tl Card. However, in 
certain situations (e.g., when using an external CSU 
equipped with a DB15 connector), it may be more con- 
venient to use the card’s optional DB15 connector 
instead. Refer to page 3-21 for more information. 
Method A 
- Tl Spans Terminated On RJ48C 
Jacks Near The MDF 
5.10 
Install Tl spans terminated on RJ48C jacks near 
the MDF as outlined in below. 
Plug one end of a four-pair, non-reversing 
(straight through), mod-to-mod line cord into 
each telephone company RJ48C jack. The other 
end of each line cord will later be plugged into 
the Tl jack on the corresponding Tl Card. 
NOTE: Make sure the connectors on the ends of 
each line cord are properly attached. If any of the 
wires are cracked or broken, Tl transmission 
problems can occur. 
Method B 
- Tl Spans Terminated On BJ4SC 
Jacks Away From The MDF 
5.11 
Install Tl spans terminated on RJ48C jacks away 
from the MDF as outlined in the following steps. Refer 
to Figure 3-9 on the next page for a diagram of the com- 
plete layout. (1) Mount one eight-conductor modular jack assem- 
bly next to each telephone company RJ48C jack. 
(2) For each modular jack assembly mounted in step 
1, also mount a corresponding eight-conductor 
modular jack assembly on the MDF backboard. 
(3) To comect the modular jack assemblies 
mounted in steps 1 and 2: 
a. 
b. Run Tl cable between the corresponding 
modular jack assemblies. 
NOTE: If the telephone company termina- 
tion is more than 2CKKl feet from the MDF, 
special Tl cable musr be used (see page 2-25 
for cable specifications). For shorter dis- 
tances, two lengths of standard two-pair voi- 
ce-frequency cable (one cable for transmit 
and one cable for receive) may be used in- 
stead. 
Wire each end of the cable onto their respec- 
tive modular jack assemblies. Refer to Figure 
3-10 on the next page for a diagram of the 
wiring. 
(4) At the telephone company termination, plug one 
end of a four-pair, non-reversing (straight 
through), mod-to-mod line cord into each RJ48C 
jack and plug the other end into the correspond- 
ing modular jack assembly next to it. 
(5) At the MDF backboard, plug one end of a four- 
pair, non-reversing (straight through), mod-to- 
mod line cord into each modular jack assembly. 
The other end of each line cord will later be 
plugged into the Tl jack on the correspondingT1 
Card. 
NOTE: Make sure the connectors on the ends of 
each line cord are properly attached. If any of the 
wires are cracked or broken, Tl transmission 
problems can occur.

be used instead. 
a. Terminate one end of a six-pair cable on each 
modular jack assembly. Refer to Figure 3-10 
on the previous page. 
(1) On the MDF backboard, mount one eight-con- 
ductor modular jack assembly for each Tl span 
termination on the telephone company RJ-type 
block(s). 
(2) Connect Tl cable between the telephone compa- 
ny terminations and the corresponding modular 
jack assemblies as follows: 
NOTE: Ifthe telephone company termination is 
more than 2000 feet from the MDF, special Tl 
cable must be used (see page 2-25 for cable spec- 
ifications). For shorter distances, two lengths of 
standard two-pair voice-frequency cable (one b. Terminate the other end of the six-pair cable 
on the right side of the Tl RJ-type terminal 
block. 
(3) Plug one end of a four-pair, non-reversing 
(straight through), mod-to-mod line cord into 
each modular jack assembly (mounted in step 1). 
The other end of each line cord will later be 
plugged into the Tl jack on the correspondingT1 
Card. 
NOTE: Make sure the connectors on the ends of 
each line cord are properly attached. If any of the 
wires are cracked or broken, Tl transmission 
problems can occur.

Using The Optional DB15 Connector In Place Of 
The BJ48C Jack 
5.13 
The three Tl installation methods described on 
the preceding pages show the Tl span being connected 
to the RJ4gC jack on the Tl Card. However, in certain 
situations (e.g., when using an external CSU equipped 
with a DB15 connector), the installer may wish to use 
the card’s optional DB15 connector instead. 
5.14 The pin functions of the Tl Card DB15 connec- 
tor (Spin subminiatnre “D” female connector) are as 
follows:

5.15 To connect the DB15 connector on theT1 Card to 
a DB15 connector coming from the Tl span, a flat, 
28AWG, twisted-pair ribbon cable with a maximum ca- 
pacitance of 16pF/ft. may be used for distances of up to 
50 feet, as shown in the figure below. For distances long- 
er than 50 feet, use the special high-speed data cable de- 
scribed in paragraph 3.131 on page 2-25.

C. COlWECTING S+lXIlON CABLES TO TEIE 
MDF 
5.16 Each type of station instrument is connected to a 
I specific station card. Digital keysets are connected to 
DKSCs. Analog keysets, analog DSS/BLF Units, and 
Attendant Computer Consoles are connected to KSCs or 
KSC-Ds. Single-line sets and playback devices are con- 
nected to SLCs and/or IDCs. 
NOTE: Resides single-line sets, playback devices, and 
off-premises extensions, IDCs can also be used to install 
DID trunks. Any combination using the eight circuits on 
the card is possible. Refer to pages 3-12 to 3-16 for DID 
trunk installation instructions. 
5.17 After the station cables are run, connect them and 
the 25pair cables to the station blocks on the MDF as 
follows: 
(1) 
(2) 
I 
Ensure that both ends of each station cable are la- 
beled with the circuit number of the associated 
station instrument. 
Terminate each station cable on the right side of 
the corresponding station block. Refer to Figures 
3-13 through 3-19 on the following pages for 
station cable terminations. 
NOTE: For simplicity, Figures 3-13,3-17, and 
3-18 show digital keysets, single-line sets, and 
playback devices being installed using one-pair 
cable and four-conductor modular jacks. Of 
course, if three-pair cable and six-conductor 
modular jacks are used instead (as is recom- 
(3) 
(5) 
(6) 
mended), extra terminal blocks and the use of 
cross-connect wiring techniques are required. 
Using enough 25pair cable to run from each 
block to each station card in the equipment cabi- 
net, make the termination cables. Attach a 
W-pin female amphenol-type connector to one 
end of each cable. Label each connector and 
cable end with the appropriate slot number (for 
example, SLOT-2). These connectors will be at- 
tached to the station cards after the telecommu- 
nication cards are installed. 
Using standard electrical tape, tape two ferrite 
split beads around each 25pair cable just below 
the amphenol-type connector (as shown in Fig- 
ure 
3-4 on page 3-13). 
NOTE: Ferrite beads must be installed to meet 
Part 15 of FCC regulations. Refer to REPLACE- 
h4ENT PARTS for the part number. 
Terminate the other end of each 25pair cable on 
the lefr side of the corresponding station block. 
NOTE: If necessary, any of the eight circuits on 
an IDC can be enabled for AC ringing to be used 
with off-premises extensions or on-premises 
AC-ringing equipment. To do this, each circuit 
can be strapped directly at the IDC terminal 
block (as shown in Figure 3-18 on page 3-28) or 
on the card itself (as described on page 3-93). 
Do 
NOT attach bridging clips until the loop re- 
sistance tests have been performed (as described 
on page 3-38).
