Table C. Manual Configuration Guide

The trunk processing options are provisioned only by switch SW7. Electronic provisioning is not available.

Table C provides a guide to ensure proper provisioning of the desired channel unit mode.

Electronic Provisioning

ADTRAN EASYMENU is used to electronically provision the unit. Connect a VT 100 terminal or a computer running a terminal emulation program to the faceplate ADMIN port or REMOTE port using a standard male-to- male RS-232 cable. The settings for the ADMIN and REMOTE ports are shown in Table D.

A null modem cable is required to connect the REMOTE port directly to a terminal.

Table D. Electronic Provisioning Settings

	ADMIN Port	REMOTE Port
Settings	9600 baud	SW2 baud
	No Parity	No Parity
	8 bits	8 bits
	1 stop bit	1 stop bit

Once connected, enter the password. The factory default password is PASSWORD in all capital letters. The password may be changed by selecting:

Common Module Menus	(2)
BCU	(1)
Configuration	(1)
Read/Write Password	(9)

Before provisioning the unit electronically, access the channel unit by selecting:

Channel Unit Menus	(3)
Desired slot	(1-24)
Provisioning	(2)
Select current operational mode	(1-4)
Select desired provisioning option	(1-*)

For additional information on EASYMENU operation or the ADTRAN Site Manager, refer to the EASYMENU User Manual, document number 61150.055L1-1 (found in the ACT 2300/1900 System Manual, document number 2150.050-3), or the Site Manager User Manual, document number 64150.075L1-1. For additional information about the LIU-3/PM see the LIU-3/PM User Manual, part number 61151.001L2-1.

Initial Turn-up

Refer to the desired operational mode in Table C for the correct provisioning options.

Transmit Attenuation

Determine the input TLP. Then use the following formula to calculate the amount of transmit attenuation to add to the circuit:

Tx Attenuation=Input TLP + Internal Tx TLP of 4.5 dBm

For example, if an input TLP level of -3 dB is to produce a level of 0dBm0 at TLP0, then the Transmit Attenuation should be set to 1.5 dB.

Receive Attenuation

Determine the output TLP. Then use the following formula to calculate the amount of receive attenuation to add to the circuit:

Rx Attenuation=Internal Rx TLP of 0 dBm) - Output

TLP

For example, if 0dBm0 at TLP0 is required to produce an Output TLP level of -3 dB, then the Receive Attenuation should be set to 3 dB. Figure 2 provides an illustration of attenuation settings.
