3.3 Peripheral Boards

 
Caution 
The peripheral boards must be firmly inserted in their slots; otherwise, contact problems can cause board failure. 

3.3.1 HXGM

Introduction

The Hicom Xpress @LAN board (HXGM) establishes the connection between Hicom 150 E OfficePro and the LAN environment. The board can provide a total of 16 B channels.

There are two versions of this board:
Hicom Xpress @LAN HXGM Voice and Data (S30810-Q2930-X)
Hicom Xpress @LAN HXGM Data only (S30810-Q2930-X100)
