3300 ICP Technician’s Handbook

Install Units

This section contains detailed information on installing and configuring the

Network Services Unit, Analog Services Unit, Peripheral Cabinet,

SUPERSET HUB, and Digital Services Unit (DSU) for the 3300 ICP.

This section also contains information on configuring embedded analog on

the MX, MXe, and CX/CXi controllers.

You can install any of the following Network Services Units (NSUs):

• Universal NSU (MSDN, PRI/QSIG, T1/D4)

• R2 NSU

• BRI NSU.

You can double the number of Universal and R2 NSUs in a system by

chaining a secondary NSU to each primary NSU connected to the

controller. BRI NSUs cannot be chained.

Some NSUs must be programmed with the ISDN Maintenance and

Administration Tool (IMAT) (see “Install and Use IMAT” on page 88).

Universal or R2 Network Services Unit

1. Mount and secure the NSU in the desired location.

2. Set the L0/L1 port DIP switches to the appropriate termination mode

and impedance (see Table 53 on page 268 and Table 58 on

page 270). The default is network termination mode. See “Network

Services Units” on page 267 for the location of these switches.

CAUTION: Provide a permanent ground for all controllers

and units, through the ground connection on each cabinet.

Tip: The CX/CXi controllers do not support Network Services Units or Analog

Services Units. The CX/CXi do support embedded trunking and embedded

analog.

CAUTION: To connect your NSU to the LAN, you must

change the default IP and gateway addresses to match an

available address on the LAN. The default address is

192.168.1.1:ffffff00. See "Programming an IP Address into

the NSU" on page 88.
