3-26 BRIM2 Installation
Chapter 3 - Installation
BRI Switches
On the rear panel of the BRIM2 is two 4-position dip switches; the TR (Terminating
Resistor) switch permits terminating the Transmit and Receive pairs with a 100 ohm
termination. The MODE switch selects the interface mode (S/T) and power feed. Note, the
TR switch pertains only to the S and T interfaces and is not used with "U" interfaces. The
Mode switch is only used for an S interface to enable power feed. The functions of the
four switch positions are given in the following table and should be set based on the user
and ISDN Line requirements.
Wiring Connectors
Before wiring any of the Modules, first 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 BRIM2 is the "LAN" connector, RJ-45 type. This connector should be
wired to the appropriate LAN point as discussed in
“LAN Connections” on page 3-15 and “LAN
Wiring Structures” on page 3-16
.
 Wire "LAN" to a 10/100 Base-T switch. A SHUB8 can be used to form the Telenium
IP
Zone.
 Tag or number wiring for maintenance.
On the rear are two RJ-45 connectors terminated to the BRI Line interface circuits. When
using a Main Cabinet (MCAB), refer to
“Main Cabinet Wiring” on page 3-29 for wiring
instructions. These connectors, refer to
Figure 3-19, should be wired to the telephone
company termination point.
