Connecting the 10Base-T Ethernet Port to a Hub . The Model
3088RC/C/AI 10Base-T interface is configured as DTE (Data Terminal
Equipment), just like a 10Base-T network interface card in a PC. There-
fore, it “expects” to connect to a 10Base-T Hub using a straight-through
RJ-45 cable. Use the diagram below to construct a cable to connect the
3088RC/C/AI to a 10Base-T Hub.
Connecting the 10Base-T Ethernet Port to a PC (DTE). The Model
3088RC/C/AI 10Base-T interface is configured as DTE (Data Terminal
Equipment). If you wish to connect the 3088RC/C/AI to another DTE
device such as a 10Base-T network interface card in a PC, you must
construct a 10Base-T crossover cable as shown in the diagram below.
Connecting the Line Interface. The Model 3088RC/C/AI is to be used
with Patton function card access products (i.e. 1092ARC) There are two
essential requirements for connecting the line interface on Model
3088RC/C/AI:
1. These units work in pairs with one 3088RC/C/AI connected to
another 3088RC/C/AI (or IM1/I) over 2 or 4-Wire Twisted pair (2 or
4-Wire operation is determined by the front function card).
2. To function properly, the Model 3088RC/C/AI needs one or two
twisted pairs of metallic wire (two or four wire). The twisted pairs
must be unconditioned, dry, metallic wire, between 19 (.9mm) and
26 AWG (.4mm) (Appendix B describes cable requirements) . Stan-
