750/850/1500 (TA 750/850/1500) platforms to provide analog voice exten-
sion. The Quad FXO resides in the TA chassis that is next to or close to the
customer’s telephone and is usually located on the customer’s premises.
This unit can be used in conjunction with the TA 750/850/1500 FXS Voice
Module, which resides in the TA 750/850/1500 that is located next to the
Central Office switch.

If TR-08 signaling format is not readily available at the CO switch, both FXO
and FXS access modules can be used for deployment. The TA 850 at the CO
will combine a number of analog lines and then multiplex them for T1 transmission to the TA 850 at the customer premise.

OVERVIEW
LED Status
Operation
The Quad FXO Voice Module goes operational upon insertion into an active
TA 750/850/1500 chassis. Once a module is inserted, the user must map an
FXO port to a network port for proper operation. Refer to the TA 850 User
Manual Channel Bank chapter (DS0 mapping section) for information.
After the initialization sequence, faceplate LEDs show the status of the analog service for each customer loop, as follows:
Off On Hook
Flashing Ringing
On Off Hook (Busy)
TESTING
Self-Test
Initiated Tests
A self-testis performed on the Quad FXO Voice Module when it is inserted
into an active TA 850 chassis. The test verifiesproper operation of critical circuits. If the test is successful, all four LEDs turn on in a predefined sequence,
the unit is placed in service, and the LEDs then return to normal operation
showing current status of the FXO.
Other tests conducted on the Quad FXO Voice Module are initiated via the
screen menus and VT 100 terminal. (See Quad FXO Voice Module Test Options
on page 3-4 for more information.)

Chapter 3. Operation
METHODS OF OPERATION
Youcan control and configurethe Quad FXO Voice Modulefrom the following sources:
• The terminal menus, allowing detailed configuration, status, and diagnostics
• SNMP, primarily for reporting alarm conditions and system status
The remainder of this section describes the menu items presented when
managingtheQuadFXOVoiceModuleviatheterminalmenu.
Access the terminal menu using either a VT-100 terminal attached to the TA
850 Base Unit’scontrol port or a Telnet session establishedthrough the Base
Unit’s Ethernet port. The TA 850 User Manual provides detailed instructions
on the operation of each of these management approaches.
The factory default password is
specified password.
TERMINAL MENU STRUCTURE
The TA 850 uses a hierarchical menu structure to provide access to all of its
features. The top-most menu level leads to submenus which are g r ouped by
functionality. All menu items display in the terminal window. To access the
Quad FXO Voice Module, activate the M

The Digital Net Loopback Test is used to loop back DS0 data coming from
the network for each channel. Received data is latched In on the appropriate
receive time slot on the receive bus. This data is then placed on the transmit
bus in the unit’s transmit time slot.
The Network On-Hook/Off-Hook Test is used to test signaling sent to the
-
network by the unit. When On-Hook Test is selected, On-Hook signaling is
sent to the network. When Off-Hook Test is selected, Off-Hook signaling is
sent to the network. The customer loop is forced On-Hook while this test is
active.
The 1004 Hz - 0dbm0 Tone Generation Test is used to send DRSsignal on the
receive path to the loop. The loop receive level that should be received is determined by the following equation:
Receive Level = 0 dB - Attenuation
