Connecting To A Dte Device; Connecting To A Dce Device; Connecting The T1 Interface - Patton electronics 2710RC Series User Manual

5. Push the Interface Driver Board gently onto the socket and re-
install into the 1001 rack.
4.3 INSTALLING THE MODEL 2710RC INTO THE CHASSIS
The Model 2710RC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other by
way of mating 50 pin card edge connectors. Use the following steps as
a guideline for installing each Model 2710RC into the rack chassis:
1. Slide the rear card into the back of the chassis along the
metal rails provided.
2. Secure the rear card using the metal screws provided.
3. Slide the card into the front of the chassis. It should meet the
rear card when it's almost all the way into the chassis.
4. Push the front card gently into the card-edge receptacle of the
rear card. It should "click" into place.
5. Secure the front card using the thumb screws.
NOTE: Since the Model 1001R14 chassis allows "hot swapping"
of cards, it is not necessary to power down the rack when you
install or remove a Model 2710RC.

4.4 CONNECTING TO A DTE DEVICE

The serial port on most rear interface cards are hard-wired as
"DCE" (Data Circuit Terminating Equipment). The interfaces are
designed to plug into a DTE such as a terminal, PC or host computer.
When making the connection to your DTE device, use a "straight
through" cable of the shortest possible length--we recommend 6 feet or
less. When purchasing or constructing an interface cable, please refer
to the pin diagrams in Appendix D and Appendix E as guides.

4.5 CONNECTING TO A DCE DEVICE

The rear interface cards on most interface modules are hard wired
as "DCE". Therefore, you must use a null modem cable when con-
necting to a modem, multiplexer or other DCE device. This cable
should be of the shortest possible length--we recommend 6 feet or
less. When purchasing or constructing a null modem interface cable,
use the pin diagrams in Appendix C as a guide.
NOTE: Pin-out requirements for null modem applications vary
between equipment manufacturers. If you have any questions
about a specific installation, please contact Patton Electronics
Technical Support.

4.6 CONNECTING THE T1 INTERFACE

The Network Line Interface is an eight position keyed modular jack
configured as a RJ-48C. This interface will need to be configured to
match the line parameters (i.e. framing, line coding, etc.) supplied by
the central office.

NOTE: If the NetLink-T1™ is being used for private short range
modem applications, the twisted pair cable connected to its port
will need to be a cross-over cable. See Appendix D for Interface
pin assignments.
