This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by
ADTRAN could void the user’s authority to operate
this equipment.
Provisioning Options
All options on the E&M/TO are provisionable either
manually, using internal slide switches, or
electronically using the craft interface on the SCU.
Figure 2 displays slide switch, refer to Figure 1 for
locations.
Note 1: Factory default settings for all switches is "OFF".
Note 2: Multiple switch activation causes a cumulative effect on
the amount of attenuation added.
Note 3: The largest transmit and receive attenuation value in
2-wire mode is 9.0 dB for TX and RX.
Note 4: The largest transmit and receive attenuation value in
4-wire mode is 12.0 dB for TX and RX.
Internal slide switches SW2 and SW3 are also used to
provision trunk processing mode and signaling,
2W/4W option, sealing current, and dial pulse
correction. Available options are displayed in Table 2
and described below.
Select TO (SW2-2) when no signaling, Transmission
Only, is required. Select EM (SW2-2 is OFF) when
E&M DC signaling supervision is required.
Select 2-wire or 4-wire using SW2-3. When 4-wire is
selected (SW2-3 is ON), the T and R leads are used
for the transmit pair, and the T1 and R1 leads are used
for the receive pair. When selected for 2-wire
operation, the T and R leads are used for both the
receive and transmit pairs.
Select SRC (SW2-4) when source sealing current is
desired.

Select Type-I, Type-II, Type-III, or Type-V E&M
signaling type by using SW4-7, SW4-8, SW4-9,
SW4-10, respectively. If more than one signaling
type is selected, the unit defaults to Type-I signaling.
Electronic Provisioning
The craft interfaces on the Total Access 1500 SCU are
used to change default options and obtain access
module status through menu screens. To access the
menu screens, connect a VT100 terminal or computer
running a terminal emulation program to the front
panel craft interface ADMIN port using a standard
male-to-male RS-232 DB-9 cable. Craft port settings
are as follows:
• 9600 Baud
• No parity
• 8 Data bits
• 1 Stop bit
Windows Hyperterminal
Windows Hyperterminal can be used as a VT100
terminal emulation program. Open Hyperterminal by
selecting PROGRAMS/ACCESSORIES/
HYPERTERMINAL. Refer to the Help section of
Hyperterminal for additional questions.
NOTE
To ensure proper display background, select
VT100 terminal emulation under SETTINGS.
Select SNK (SW2-5) when sink sealing current is
desired. If both are selected, the unit defaults to
NONE. Sealing current is only available when both
4-wire and TO modes are selected.
Select EPD option (SW4-5) for delayed trunk
processing. When this option is selected, the E-lead
appears on-hook when trunk processing begins. The
E-lead then goes off-hook (appears busy) 2.5 seconds
after trunk processing begins.
Select EPI option (SW4-6) for immediate trunk
processing. This setting causes the E-lead to go
off-hook immediately after trunk processing begins,
and remains so until trunk processing is complete.
61180402L1-5C
When EPI and EPD options are not selected, the
E-lead is forced on-hook during trunk processing and
remains so until trunk processing is complete. If both
EPD and EPI are selected, unit defaults to NONE.
Password
Password protection is factory disabled. If password
protection is enabled, then the SCU will display the
log on screen, and a valid user ID and password are
required to access the menus. The factory default
password is PASSWORD, in upper case letters.
Figure 3 illustrates the E&M/TO menu tree.
Menu Navigation
To traverse through the menus, select the desired entry
and press ENTER. To work backwards in the menu
press the ESC (escape) key.

Initial Turnup
To set the transmit and receive attenuation, first
provision the unit for 2-wire or 4-wire mode.
Transmit Attenuation
Determine the input TLP level. Then use the
following formula to calculate the amount of transmit
attenuation to add to the circuit.
Transmit Attenuation=Input TLP level + Transmit
Circuit Gain
where Transmit Circuit Gain =
0.0 dB (2-wire)
3.5 dB (4-wire)
For example, if the unit is in 2-wire mode and the
input TLP is +3, then to achieve a 0dBm0 TLP0
Transmit Attenuation is:
+3 dBm + 0 dB = 3 dB
If the unit is in 4-wire mode and the input TLP is -3
dB, then to achieve a 0 dBm0 TLP0 the Transmit
4
Attenuation is:
-3 dBm + 3.5 dB = 0.5 dB
Receive Attenuation
Determine the desired output TLP level. Then use the
following formula to calculate the amount of receive
attenuation to add to the circuit.
Receive Attenuation=Receive Circuit Gain – Output
TLP level
where Receive Circuit Gain =
0.0 dB (2-wire)
8.5 dB (4-wire)
For example, if the unit is in 2-wire mode, the TLP
reference level is 0 dBm0, and the desired output TLP
is -3.0 dB, then the Receive Attenuation is:
– (-3 dB) = 3 dB
For example, if the unit is in 4-w ire mode, and the
desired output TLP is -3 dB, then the Receive
Attenuation is:
8.5 dB – (-3 dB) = 11.5 dB
