Instructions for Installing the Module
To install the FXS/DPO, perform the following steps:
1. If present, remove the Access Module Blank (P/N
1175099L1) from the appropriate access module
slot of the Total Access chassis.
2. Pull the ejector latch, located on the lower lefthand side of the FXS/DPO front panel, from its
closed position.
3. Hold the FXS/DPO by the front panel while
supporting the bottom edge of the module with the
ejector latch opened to engage the chassis edge.
4. Align the module edges to fit in the lower and
upper guide grooves for the access module slot.
5. Slide the module into the access module slot.
Simultaneous thumb pressure at the top (above the
STATUS LED) and at the bottom (below the
electrostatic caution symbol) of the module will
ensure that the module is firmly positioned against
the backplane of the chassis.

Front Panel LEDs
The FXS/DPO provides front panel LEDs to display
status information. See Table 2 for a listing of the front
panel LEDs and their indications.
Time Slot Assignment
For time slot assignments in the Dual T1 mode and in
the Quad T1 mode, see Tab le 3 on page 4. The Total
Access 1500 platform can have multiple time slots in
the T1 data stream assigned to each physical slot in the
channel bank. The Total Access 1500 allows craftselectable time slots using the electronic provisioning
interface. The system will automatically map DS0s in
the T1 as determined by the Line Interface Unit (LIU)
operational configuration. Manual mapping is available
via the LIU menu.
Connections
Four 50-pin male amphenol connectors on the 23-inch
Total Access 1500 backplane and three on the 19-inch
chassis packplane provide the interconnect wiring for
each of the access module physical slots. The FXS/DPO
requires
19-inch chassis, Slots 1-6 use
Slots 13-18 use
P1 (Pair 1 T/R) on the 23-inch chassis. In the
P1, Slots 7-12 use P2, and
P3. See Table 3 on page 4 for wiring
interconnect details.
3. PROVISIONING
Provisioning options are either hardware provisioned;
using DIP switches on the FXS/DPO printed circuit
board, or software provisioned; using the craft interface
(
ADMIN) on the System Controller Unit (SCU).
Selection of hardware or software provisioning is determined by the front panel recessed pushbutton
AP (see

This option sets the conversion from E&M (2-state) signaling
on the PCM interface to loop start or ground start signaling on
the loop. This option MUST be configured for channel
operation, as the default value (Tandem Inactive) will not run
the state machine.
This option configures the E7M trunk as immediate or wink
start for both the RX and TX direction. With wink start, a
wink is sent back to the network from the FXS/DPO card
before ringing to signal line seizure for inbound calls. For
outgoing calls, a wink must be received from the switch to the
FXS/DPO card to indicate trunk seizure for the call.
This option configures answer supervision for the associated
voice port. Answer supervision is indicated by reverse battery
polarity when Reverse Battery option is set. This is valid for
outbound calls only.
This option is used to generate a 5-second dial tone from the
associated FXS/DPO port when off-hook is detected. The dial
tone provided by the FXS/DPO times out after 5 seconds and
is not broken by digit input.
When this option is enabled, a ringback tone is provided

5. MAINTENANCE
The Total Access FXS/DPO does not require routine
maintenance for normal operation.
• Digital Network Loopback
• 1004 Hz Tone Generation
• Network Hook Test
• Customer Ringing Test
These test are used to support circuit turn-up and
maintenance efforts. Test functions can be activated
locally via the
ADMIN port on the SCU, or remotely via
Telnet or SNMP and are initiated on an individual port
basis. The test are described below.
Digital Network Loopback Test
The Digital Network Loopback test activates a
loopback path that takes the DS0 data received from the
network and transmits it back to the network in the
appropriate transmit time slot.
1004 Hz Tone Generation Test
The 1004 Hz Tone Generation Test generates a 1004 Hz
Digital Reference Signal (DRS) tone toward the T1
network (0 dBm fixed), toward the customer loop (RX
TLP setting), or both directions simultaneously. While
sending the DRS tone toward the customer loop the
transmit audio path (towards the T1 network) will be
interrupted.
Network Hook Test
The Network Hook Test forces the AB signaling states
towards the T1 network. The bits are set based upon the
operating mode of the channel unit.
ADTRAN does not recommend that repairs be
attempted in the field. Repair services may be obtained
by returning the defective unit to ADTRAN. Refer to
the Warranty and Customer Service section for further
