Installation

The extension can be run up to approximately three miles (5 km)
using 24 AWG wiring.
Basic Port Package
A maximum of six OPX(2)-U( ) ETUs can be installed in slots
S1~S8.
The maximum number of OPX(2)-U( ) ETUs that can be installed
depends on other station cards installed. The system is limited by 64
trunk and station ports combined. This ETU shares the total number
of station ports in the system.
Calculating maximum capacity is based on the system having a
minimum of eight Electronic Station Interface (ESI) ports, four trunk
ports and a PKUII-U Unit installed. When 2-port trunk interface
ETUs are installed the system uses four ports from its maximum port
capacity.
Expanded Port Package

system.
Calculating maximum capacity is based on the system having a
minimum of eight Electronic Station Interface (ESI) ports, four trunk
ports and a PKUII-U Unit installed. When 2-port trunk interface
