2. INSTALLATION
CAUTION
This equipment contains static sensitive
components. Ensure proper ESD procedures
are followed when handling or installing this
equipment.
After unpacking the unit, inspect it for shipping
damage. If damage is noted, file a claim with the
carrier, and then contact ADTRAN Customer Service
(see Warranty and Customer Service).
The ACT LIU, List 1 plugs directly into the ADTRAN
ACT 2300/1900 channel bank. No installatior wiring
is required.
The ACT LIU should be installed in the ACT 2300 or
ACT 1900 channel banks in the slot labeled LIU. To
install the ACT LIU, grasp the unit by the faceplate
and push the unit into the connector until the unit is
fully seated. Lock the unit into position with the two
faceplate screws.
NOTE
The T1 interface (DSX-1) is intended to be
connected to intra-building wiring only.
Provisioning Options
The ACT LIU is provisioned either manually, using
an internal nine-position internal DIP switch (SW2)
and a two-position faceplate-mounted DIP switch, or
electronically using a menu driven program called
EASYMENU
TM
. EASYMENU
TM
is accessed through
either the faceplate administrative port (ADMIN) of
the Bank Controller Unit (BCU) or the remote port
(REMOTE) on the rear of the ACT 2300/1900
chassis. Manual provisioning must be completed
before the LIU is inserted into the bank, while
electronic provisioning is completed following system
turn-up.
Manual Provisioning
DIP switch 2 (SW2) and the two-position faceplate-
mounted switch are used to manually provision the
unit.
Switch Option Settings
Switch 2 (SW2) selects line equalization, Payload or
Line loopback at the remote bank, line code format
[binary 8 zero substitution (B8ZS) or alternate mark
inversion (AMI), framing format [superframe (SF) or
extended superframe (ESF)], and timing source (local,
loop, or external). Figure 2 shows the location of
SW2 and Table 1 provides option settings.
NOTE
Switch setting SW2-3, Payload (PYLD) or
Line (LINE) loopback, works in conjunction
with the front-panel, remote-loopback switch
of the ACT LIU. The loopback selected using
SW2-3 defines the type of loopback the
faceplate switch activates at the remote
channel bank.
Two-position Faceplate Switch
The two-position rocker switch shown in Figure 1
selects either the Operating or Test mode of the LIU.
The top switch enables or disables a local loopback
function. The bottom switch enables or disables a
remote loopback function which loops the signal back
at the remote bank. In both cases, moving the switch
to the left position enables the test function. Putting
both switches in the Off position (default) selects
normal operation.
Electronic Provisioning
ADTRAN EASYMENU
TM
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. Table 2 shows
the settings for the ADMIN and REMOTE ports.
