1.4.5 Repair Service
All warranty repairs are performed at no cost. Positron reserves the right to repair
or replace any equipment that has been found to be defective.
For information about out-of-warranty repairs, contact Positron’s Repair
Department. Due to the varied nature of repairs, no specific turnaround can be
guaranteed, but average turnaround time is 20 working days from date of receipt.
In emergency situations, special arrangements can be made. All repaired items
are warranted for a period of 90 days.
Before returning any items to Positron for repair, warranty repair or replacement,
call the Repair department to obtain a Return Material Authorization (RMA)
number. Parts returned without RMA numbers cannot be accepted. The RMA
number must always be clearly marked on all boxes, crates, and shipping
documents. Bulk repairs (more than five items) will require additional processing
time, so please take this into consideration when requesting an RMA number.
To accelerate the repair process, whenever possible, include a report detailing the
reason for return with the unit(s). Also, please include the name and phone
number of a person who can be contacted should our Repair department need
further information.
When packing items being returned for repair, please ensure they are properly
packed to avoid further damage. Plug-in cards should never be shipped while
installed in a shelf; this will cause damage that can extend the repair period

Teleline Plug-in 4-wire Enhanced T1
2.1 Introduction
Each plug-in card (751329R2 and 751329SP) provides high voltage isolation
between an incoming 4-wire T1 carrier line and a data transmitting/receiving
device located in the substation. These units are designed for use with any of the
new generation Teleline Isolator multi-card shelves.
Model 751329R2 is an enhanced T1 card. The key enhancement consists of more
effective use of Surface Mount Technology (SMT) for increased reliability and
greater Mean Time Between Failures (MTBF).
Model 751329SP is an enhanced T1 card with span power. Its key enhancement
consists of more effective use of SMT for increased reliability and greater MTBF,
and offers a span powering option using -48 Vdc to provide 60 mA simplex current
on the station side.
Model 751329 has been manufacture discontinued and is replaced by the new
enhanced T1 cards.
2.1.1 Features
Features for models 751329R2 and 751329SP include the following:
QCards are suitable for transmission at frequencies up to 5 MHz provided the
data line is conditioned for operation
QIsolation of 50 kVrms (70 kV peak) while maintaining full communication
between terminals
QCommunication maintained across the gap by isolation transformers that
provide low-loss low-distortion transmission
QCards are passive and do not require power to operate, except when using
the span power option
QThe Teleline shelf power can be maintained during the installation of the cards
QSimplex current termination is provided on the CO side. The current will not
be transferred to the Station side with Span Power

Applications
2.2 Applications
The applications of the Plug-in 4-wire T1 Carrier card include the following:
QT1 Carrier (1.544 Mb/s)
QE1 Carrier (2.048 Mb/s)
Figure 3: High Voltage Interface
QWhen model 751329R2 is used, the NTU must be locally powered.
QWhen model 751329SP is used, an internal or external -48 Vdc power
supply is required to provide Station side simplex current, the NTU will not
require local powering. (Refer to the appropriate Positron Power shelf
manual for power supply information.)

2.3 Hardware Description
Each card (751329R2 and 751329SP) has two sides:
QThe Station side is located on the upper portion of the card.
QThe CO side is located on the lower portion of the card.
The isolation transformers separate the Station side from the CO side, creating a
13.2 cm (5¼ inch) isolation gap.
For the 751329R2 station side, both transformer center taps are grounded,
For the 751329SP station side, the NIU's RX pair (Tip1 & Ring1 of 751329SP)
center tap is grounded, the NIU's TX pair (TipA & RingA of 751329SP) center tap
is connected to -48 Vdc via a 60 mA current source.
On the CO side, the TX and RX pair center taps are connected with an effective
200 Ohm impedance to allow simplex loop current to flow across the pairs.
