4.3.2 CONNECTING THE LINE INTERFACE
The Model IM2RC/F is to be used with Patton function card access products (i.e. 1045RC, 1092RC, 1092ARC, 2500RC) that support 64k/128k synchronous data rates. There are two essential requirements for connecting the line interface on Model IM2RC/F:
1.These units work in pairs. Both units at the end of the twisted pair must have the proper
2.To function properly, the Model IM2RC/F needs one or two twisted pairs of metallic wire. The twisted pairs must be unconditioned, dry, metallic wire, between 19 (.9mm) and 26 AWG (.4mm) (Appendix B describes cable requirements) . Standard
