LAN Cable Termination

Several methods are available for terminating the horizontal cable runs. Oracle MICROS recommends the 110 Connect system by AMP or other suppliers. This system uses the reliable 110 style punch-down RJ45 modular jack and are available in both shielded and non-shielded versions.

A second termination method is based on the 8-pin RJ45 modular “keystone” insulation displacement connector, similar to those available for MICROS IDN devices. The cable is attached to this connector by placing all conductors in the appropriate connector cap, and then forcing the connector cap into place.

The figure below shows a “keystone” modular jack on the left and a 110 modular connector on the right.

In addition, there are two methods for terminating the cable. The figures below show how to terminate cables at the faceplate connectors using the ANSI/TIA/EIA-568-A or ANSI/TIA/EIA- 568-B cabling standard.

ANSI/TIA/EIA-568-B.1-2001 specifies that horizontal cables are terminated using the T568A pin/pair assignments, or optionally terminated with the T568B pin pairs to accommodate certain cabling systems. Mixing T568A terminated horizontal cables with T568B terminated patch cords (or the reverse) is not recommended.

Please note that pins 1-2, 3-6, 4-5, and 7-8 are +/- signal pairs twisted with each other within the cable. You must maintain these signal pairs at each end of the cable as well as the patch cables.
