The rear of the HX Controller chassis (see Figure 2 below) provides the following:
• Power Module Bay: Houses an internal power distribution module with a 3-pin DIN connector
for connecting an external 120W, +24VDC power supply unit.
• External Chassis Connector: A DB-15 (15-pin D-subminiature socket) connector for attaching
a DEI chassis.
• Music Jack: A 3.5 mm, two-conductor (stereo), mini phone jack for connecting an external
music source that can be heard by callers when they are placed on hold or camped on, or used
to provide background music to phone users. Due to hardware changes, this jack requires a
slightly louder input than the jack on the CS Controller.
• Paging Jack: A 3.5 mm, two-conductor (mono), mini phone jack with an output impedance of
600 ohms for connecting external paging speaker equipment for paging to large areas like
warehouses or loading docks.
•
Expansion Module Bays:
Four smaller bays for adding the 16-port Digital Desktop Module
(DDM-16) or any of the existing station/trunk modules supported in the original CS Controller
chassis.
• Ground Lug: For properly grounding the chassis.
•
HX Processor Module Bay:
A single large bay to house the HX Processor Module.
• Single Line (FXS) Jacks: Two six-pin RJ-14 jacks that allow up to four single line devices to
be connected directly to the system without the need for single line expansion modules.
• Loop Start (FXO) Jacks: Two six-pin RJ-14 jacks that allow up to four loop start trunks to be
connected directly to the system without the need for loop start expansion modules.
• USB Ports: Two 2.0 type A connectors for Uninterruptable Power Supply (UPS) monitoring or
for connecting a USB hub to provide additional ports.
• Auxiliary Port: Reserved for possible future use.
•
Gigabit Ethernet LAN Port:
An auto-sensing (10/100/1000 Mbps) eight-pin RJ-45 jack for
connecting the system to the customer’s LAN or to a programming PC. It is configured to
auto-negotiate both speed and duplex mode. The LED on the left side of the jack is lit for a
