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.

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.
