3-22 LGCM4 Installation
Chapter 3 - Installation
LGCM4 Installation
The LGCM4 may be installed in any slot of the Main Cabinet, except for slot ten, or may
be installed anywhere in the Desk Mount Holder. The LGCM4 provides a gateway between
standard PSTN Loop/Ground Start Lines and the
Telenium
IP
KTS. The LGCM4 can support
four PSTN Lines.
LEDs
In addition to the Power and LAN LEDs, the LGCM4 has four status LEDs. These LEDs
indicate that the individual PSTN Lines are busy (LED on), idle (LED off) or ringing (LED
flashing).
Wiring Connectors
Before wiring any of the Modules, connect the "GND" screw on the back of the Module to a known
earth ground. Refer to
“Module Grounding” on page 3-14.
On the front of the LGCM4 is the RJ-45 type "LAN" connector. This connector should be
wired to the appropriate LAN points.
 Wire "LAN" to a 10/100 Base-T switch. A SHUB8 can be used to form the Telenium
IP
Zone.
 Ta g or number wiring for maintenance.
On the rear are four RJ-11 connectors terminated which should be wired to the telephone
company termination point. When using a Main Cabinet, refer to
“Main Cabinet Wiring” on
page 3-29
for wiring instructions.
 Wire each RJ-11 to a CO Line at the PSTN termination point/MDF.
 Tag or number wiring for maintenance.
AC/DC Adapter
Assure the AC/DC Adapter is plugged into a live AC outlet and the Module Power jack.
DIDM2 Installation
The DIDM2 may be installed in any slot of the Main Cabinet, except for slot ten, or may
be installed anywhere in the Desk Mount Holder. The DIDM2 provides a gateway between
standard telephone company DID Lines and the
Telenium
IP
KTS.
The basic DIDM2 can support two DID Lines and can be expanded with the DIDU2 by an
additional two Lines for a total of four DID Lines. If required, install the optional DIDU2
expansion unit before installing or wiring the DIDM2.
LEDs
In addition to the Power and LAN LEDs, the DIDM2 has four status LEDs for each DID
Line. These LEDs indicate that the DID Line is in-use (LED on), signaling (LED flashing),
or idle (LED off). Note that the LEDs for circuits 3 and 4 will only function if the DIDU2 is
installed.
CAUTION: Before connecting the LAN from SHUB8, the appropriate switch
for DTE power must be in the "OFF" position.
