Interconnection Summary
The following illustrations provide a summary of the different interconnections between the ICP
and associated peripheral cabinets. The analog interfaces both on the ASU and on the
embedded Analog Main Board/Analog Option Board (AMB/AOB) have not been shown. These
are standard telecom wiring, and likely use RJ-11 connections with a single pair.
Certain connections, such as those that terminate on the BRI or PRI interfaces are considered
as telecom connections and rules that apply to this type of cable must be applied. Typically the
connections to these interfaces are made with RJ-45 connectors and the cable pairs used are
compatible with CAT 5 wiring. In a structured wiring infrastructure, it is possible to mix both data
and digital telecom and use common CAT 5 cable throughout. Only at the MDF/Termination
point will the cables be routed in different directions. CAT 3 cable may not provide the correct
connections pairs and would require different implementations for data a telecom.
