Installing

Note: The 3300 BRI NSU is set for 75 ohms impedance when connected to a digital trunking NSU running E1 DPNSS. The 3300 Universal NSU is also set for 75 ohms impedance.

Note: A Category 5 connection from the 3300 BRI NSU E1 port to a 3300 Universal NSU that is running E1 DPNSS. E1 connections as TX and RX pairs in RJ-45. Option to ground one side of TX and or RX (using DIP switch) to use with coax adapter.

Note: The 3300 BRI NSU is connected to an appropriate device (such as a PSTN or ISDN device) from a 25-pair Amphenol connector.

Setting Up the Maintenance PC

To install, configure, and maintain the 3300 BRI NSU, you must connect it to a maintenance computer. The computer must be running DOS and have a communications program (such as ProComm Plus ©) installed.

To connect a maintenance PC to the 3300 BRI NSU:

1.Using the RJ45 to 9-pin D-type MMI cable, connect the RS-232 port on the 3300 BRI NSU to COM port 1 or 2 on the PC.

2.Set up the communications program on COM port 1 or 2 with the following parameters: 9600 baud, 8 data bits, no parity, 1 stop bit, ASCII character set, and XON/XOFF flow control.

NSU Chaining

NSU chaining refers to the physical connection of two NSUs together, on one fiber interface, from the Controller. BRI NSUs may not be chained.

To connect two NSUs to the Controller:

1.Connect the first NSU to the controller through a fiber connection from the fiber port on the NSU to the fiber port on the 3300 Controller.

2.Using a CAT5 crossover cable make a connection from CIM2 on the first NSU to CIM1 on the second NSU.

3.Connect power to the NSU.

Note: The first NSU must have the Message Link dip switch set to 1, up. The second NSU must have the Message Link dip switch set to 2, down.

Install the 3300 Universal ASU

Before you begin, ensure that there is a free CIM port on the 3300 Controller.

To install the 3300 Universal ASU:

1.Mount the 3300 Universal ASU in the 19-inch rack (if applicable).

2.Connect the supplied Cross-over Category 5 cable with RJ-45 connector to the CIM port on the 3300 Universal ASU and a free CIM port on the 3300 Controller. Note that up to four ASUs can be connected to the 3300 Controller.
