HANDLING PRECAUTIONS REQUIRED.
61180008L1-5D Issue 4, May 2006 3
CAUTION
Electronic modules can be damaged by ESD.
When handling modules, wear an antistatic
discharge wrist strap to prevent damage to
electronic components. Place modules in
antistatic packing material when transporting
or storing. When working on modules, always
place them on an approved antistatic mat that is
electrically grounded.
Installing the Module
The Total Access 1500 SCU plugs directly into the third
slot from the left, labeled
SCU, in the common module
area of the Total Access 1500 chassis.
WARNING
Attempting to insert the SCU in any other slot
can damage the SCU.
CAUTION
This release of the SCU software is designed to
operate with LIU software release T07 or later
to support feature enhancements. LIU software
can be found at www.adtran.com
under the
Service/Support page.
To Install the SCU, perform the following steps:
1. Pull the ejector latch, located at the center of the
SCU front panel, from its closed position.
2. Hold the unit by the front panel while supporting
the bottom edge with the ejector latch opened to
engage the chassis edge.
3. Align the module edges to fit in the lower and
upper guide grooves for the
SCU slot.
4. Slide the SCU into the
SCU slot. Simultaneous
thumb pressure at the top and at the bottom of the
SCU front panel will ensure that the SCU is firmly
positioned against the backplane of the chassis.
5. Secure the SCU in place by pushing in on the
ejector latch.
All power, ground, and administrative wiring should
now be completed on the Total Access 1500 chassis.
The next procedure is to apply power to the chassis with
an SCU in place, and ensure that the SCU properly
powers up and successfully completes its power-on
self-test routine. To verify that the SCU completed the
self-test routine perform the following steps:
1. Insert a fuse into the fuse and alarm panel serving
either the A or B power feeds to the Total Access
1500 chassis. The fuse should be selected with an
amperage appropriate for the intended use of the
Total Access 1500 chassis (5 amp maximum).
2. Verify that the SCU power-on self-test routine is
successfully completed. The LEDs will all simulta-
neously flash, then the
ACO, HST, and MLT BSY
LEDs will flash four times staying on the last time.
Once these LEDs turn off, the front panel will
represent the true status of the SCU. This can take
more than one minute.
NOTE
Once successfully powered up, if only A or B
power is supplied, the SCU will reflect a
MNR
alarm for A (or B) power failure.
Front Panel LEDs and Switch
The SCU front panel LEDs illuminate to indicate the
SCU’s status. See Table 2 on page 4 for a description of
front panel LEDs and switch. The Alarm Cut Off (
ACO)
switch is provided to disable audible alarms.
3. OPERATION
The SCU is the user access point to the Total Access
1500 system, and supports a number of user physical
interfaces.
Physical Interfaces
The SCU supports a craft port, an X.25 port, and an
Ethernet port.
Craft Port
The SCU provides an RS-232 compatible serial
asynchronous craft access port. Physical access is
attained by connecting a male-ended DB-9 cable to the
female DB-9 connector, labeled
ADMIN, on the SCU
front panel. This port can operate at various baud rates
and is limited to 8-bit asynchronous data with no parity,
one stop bit (8-N-1). Minimal 3-wire functionality (pins
2, 3, and 5) is also accommodated. This port operates as
a DCE; pin assignments are detailed in Table 3 on
page 4.
4 Issue 4, May 2006 61180008L1-5D
X.25 Port
The SCU supports a synchronous RS-232 compatible
serial interface to be used in conjunction with an X.25
network. The unit includes PAD functions onboard so
an external PAD is not required for operation with the
X.25 network. Physical access uses a 25-pin female
DB-25 connector (J34) on the rear of the Total Access
1500 chassis. The X.25 connector pin assignments are
detailed in Table 4.
This port operates as a DTE and is configured for the
following settings:
• 1-way in or 2-way operation
• Up to four SVCs
• Up to 64 kbps (synchronous)
• Packet size: 128 bytes
• Packet window: 2
• n2 retry limit: 3
• T1 ACK timer: 20 seconds
• T3 time out: 3 seconds
• k window size: 2

Setting the Target ID
A unique TID must be given to each chassis of a chained
RS-485 cluster. To set the TID in the Total Access 1500
SCU, perform the following:
1. Logon to the system.
2. From the Total Access 1500 Main Menu, select
option 1,
System Controller, and press Enter.
3. From the
System Controller menu, select option 2,
Provisioning, and press Enter.
4. From the
Provisioning menu, select option 6,
Target ID (TID), and press Enter.
5. Enter the appropriate TID, and press
Enter.
NOTE
The TID can consist of up to 20 characters. The
first character must be a letter. The remaining
characters except the last character can be
alphanumeric or a hyphen. The last character
must be alphanumeric.
An example of a TID follows:
HTVLALEXD01
Where:
HTVL Designates the city
AL Designates the state
EX Identifies the CO or RT
D Identifies the equipment type (“D” is
administrative equipment)
01 Identifies the piece of equipment of that
type at the CO
Alarm Processing
The SCU monitors the status of each line card and
provides necessary alarm processing to determine the
overall alarm state of the system.
Alarm Outputs
The SCU determines alarm states and reports these
results via onboard alarm interfaces and through active
user access channels. Each onboard alarm interface
consists of Form-C relay contacts to provide Common
(COM), Normally Open (NO), and Normally Closed
(NC) functionality. Physical access to the relay contacts
is attained by way of two wire-wrap posts per alarm
function. These posts are located on the rear panel of the
Total Access 1500 chassis. The alarm outputs shown in
Table 5 are supported:
The SCU provides front panel LEDs (see Table 2 on
page 4) to indicate the status of the Total Access 1500
system and Alarm Cut Off (ACO) state.
Alarm Inputs
The SCU supports up to four external alarm, status, or
control inputs. Circuitry on the SCU accepts a –48 VDC
signal as an active state. Physical access to these inputs
is attained by way of two wire-wrap posts per input
function located on the rear panel of the Total Access
1500 chassis. The alarm inputs shown in Table 6 are
supported:
NOTE
The front panel mounted
ACO switch is used to
cut off an alarm.

System Configuration Archive (SCA)
The SCA system menus (see Figure 4) are used to
manually or automatically save provisioning infor-
mation for all installed cards to a remote TFTP server
for possible restoration at a later time. In addition to the
obvious use for fast recovery of provisioning infor-
mation in the case of flood or fire, the SCA system can
be used to “clone” baseline configurations to new instal-
lations so that only a few specific provisions need to be
altered, significantly reducing initial setup time.
The menus and SNMP system allows the system admin-
istrator to perform automatic or manual save and
restores of SCA information to a TFTP server.
Automatic save operations can be scheduled to occur
after a specific time of day so that installations with
large numbers of Total Access 1500 systems can reduce
simultaneous SCA network traffic.
While SCA save operations backup information from
all modules present in the chassis, the restore operation
allows the administrator to control the type of provi-
sions to be restored to the SCU, and whether or not to
restore provisions to specific common modules and
access modules.

SCA Autosave Provisioning
The SCA Autosave Provisioning menu (Figure 5) is
used to display and configure provisions related to SCA
Autosave operations.
Autosave System
This field is used to enable or disable the SCA autosave
functions.
Autosave Only If Prov Changes
This field is used to reduce the number of redundant
Autosave operations and SCA files on the TFTP server
by instructing the SCU to perform Autosave operations
only if provisions have been changed on the SCU, LIU,
or Access Module.
The next three fields are collectively used to construct
the name of the Autosave SCA file on the TFTP server.
Autosave Filename Prefix
The Autosave filename Prefix is a 0 to 30 character
string that will be used to construct the first part of the
SCA filename.
Autosave Filename Suffix
The Autosave Filename suffix is a 0 to 8 character string
that will be used to construct the trailing type, or extent
portion of the SCA filename. If a period is desired
between the first and second part of the SCA filename,
it should be placed within this suffix field.
Max Autosave File Instances
The Max Autosave File Instances field determines the
maximum number of SCA filenames to save to the
TFTP server. This is often called a backup file rotation
scheme, where the last “N” files are always maintained
on the backup medium (the TFTP server in this case).
For example, if this field is set to a value of seven (7),
seven uniquely named SCA files will be written to the
TFTP server. After the seventh file has been written, the
count will recycle to one, and the first file will be
overwritten. The sequence 1 through 7 continually
cycles until the value of this field is changed, at which
time it will be reset to one.

61180008L1-5D Issue 4, May 2006 15
The generated SCA filename will be of the form
(excluding parentheses):
(Prefix)_(Instance)(Suffix)
where:
• Prefix is the value of filename prefix field
• Instance is decimal number between 1 and the
max AutoSave instances field
• Suffix is the value of the filename suffix field
For example, if the prefix is “Flintville,” the next
Autosave file instance is 3, and the suffix is “.sca”, the
name of the next SCA Autosave filename will be
“Flintville_3.sca”.
AutoSave Time (Hour) and AutoSave Time (Minute)
These two fields represent a time of day after which the
Autosave SCA file can be written to the remote TFTP
server. These fields allow the system administrator to
configure the Total Access 1500 systems on the
customer network to write their Autosave SCA files at
different times so as to prevent network congestion that
might occur if all the systems attempted to save their
SCA files at the same time.
If, for example, the
Autosave Time (Hour) field was set
to “3”, and
Autosave Time (Minute) field was set to
“15”, the SCU would attempt an SCA Autosave
operation shortly after 03:15 in the morning.
SCA Restore Commons Provisioning
The SCA Restore Commons Provisioning menu (see
Figure 6) is used to display and configure provisions
related to SCA restore SCU and LIU provisions.
Restore Provisions to Online LIU
If this field is set to disabled, no Online LIU provisions
will be altered during an SCA restore regardless of the
other settings on this screen.
Restore Provisions to Offline LIU
If this field is set to disabled, no Offline LIU provisions
will be altered during an SCA restore regardless of the
other settings on this screen.
Restore Provisions to SCU
This field acts as a global override to disable the restore
of all SCU provisions, and is useful in protecting the
current SCU settings during SCA restore operations to
common modules.
If this field is set to disabled, no SCU provisions will be
altered during an SCA restore regardless of the other
settings on this screen.

Restore SCU SCA Provisions
This field controls whether or not SCA-related provi-
sions should be restored on the common modules.
All SCA provisions such as SCA Autosave, filename,
SCU and LIU Module restore settings, etc. will be
overwritten if this field is set to
Enable.
Restore SCU Network Provisions
This field controls whether or not general IP network-
related provisions should be restored on the SCU.
General IP network-related provisions include the
various Telnet, DNS, and firmware TFTP server
settings. This field does not control the restore of
network interface settings (such as IP, Netmask, and
Gateway.)
Restore SCU Network Interface Provisions
This field controls whether or not network interface
related settings (such as IP Address, IP Subnet Mask,
and IP Default Gateway) for the Ethernet interface are
to be restored on the SCU.
Restore SCU SNMP Provisions
This field controls whether or not SNMP-related provi-
sions should be restored on the SCU.
SNMP-related provisions include such SNMP items as
Trap Hosts, System Name, Location, and Contact
strings, as well as the public and private SNMP
community strings.
Restore SCU Security System Provisions
This field controls whether or not Security System
related provisions should be restored on the SCU.
Security System provisions include such items as
system and user names and passwords.
SCA Restore Module Provisioning
The SCA Restore Module Provisioning menu (see
Figure 7) is used to display and configure provisions
related to SCA restore of Access Module provisions.
Slot
These columns represent each of the Total Access 1500
access module slots 1 through 24.
Module Name
These columns represent the card type identification of
the access module currently installed in the corre-
sponding slot of the Total Access 1500 chassis.
Restore
These columns represent whether or not SCA restore to
the corresponding slot has been enabled by the adminis-
trator. If the field is displayed in inverse video, some
condition (such as an empty slot, user disable, or
exclusion due to the card being In-Service) exists that
prevents SCA restore to this slot.

Pre-provision Empty Slots
This field controls whether or not SCA restore opera-
tions should attempt to pre-provision empty slots.
If an empty slot is pre-provisioned, inserting an access
module matching the type of module present in the SCA
file for that slot will result in automatic reprovisioning
of the module to the settings present in the SCA file.
