3.2.5 CGUM (Not for U.S.)

Introduction

The clock generator upside-down module (CGUM) (S30807-Q6909-X) is an optional plug-in module for the CBPC control board (Hicom 150 E OfficeCom).

The CGUM must be inserted for applications that require greater clock accuracy:

Hicom cordless EM
Digital tie traffic (CorNet-N, QSIG), exclusively in the main CS (clock master)

There are plans to replace the CGUM board (S30807-Q6909-X) with CGMC (S30807-Q6924-X).

3.2.6 CONBO

Introduction

Configuring the Hicom 150 E OfficePro with three cabinets ("7-slot" cabinets) requires that the CONBO (connection board) be inserted in the first slot in EC2. This board

Supplies the HDLC, PCM and clock signals from the first expansion cabinet (EC1) to the second (EC2).
Generates an ID signal that informs the CBMOD of the existence of a third cabinet

You do not need a CONBO board if you are using Hicom 150 E OfficePro "Extended" ("8-slot" cabinets).
