Introduction
QUAD FXS VOICE MODULE OVERVIEW
The Quad FXS Voice Module (see Figure 1-1) is for use in the Total Access
750/850/1500 (TA 750/850/1500) platforms to provide analog voice exten-
sion. The Quad FXS 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 FXO Voice
Module, which resides in the TA 750/850/1500 that is located next to the
Central Office switch.
Figure 1-1. Quad FXS Voice Module
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. If using the TR-08 signaling
option, the Quad FXS can communicate directly with the Central Office
Switch without needing a Quad FXO.

circuits to which i t interfaces, from the TA 850 front panel. Additional status
information is available via the terminal menus, accessible through either a
VT-100 terminal connected to the TA 850 control port or via a Telnet session
established through the Base Unit’s Ethernet port.

Operation
TheQuadFXSVoiceModulegoesoperationaluponinsertionintoanactive
TA 750/850/1500 chassis. Once the unit is inserted, it must be mapped to a
network interface 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

TESTING
Self-Test
Initiated Tests
A self-test is performed on the Quad FXS Voice Module when it is inserted
into an active TA 850 chassis. The test verifies proper 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 FXS.
Other tests conducted on the Quad FXS Voice Module are initiated via the
screen menus and VT 100 terminal. (See Quad FXS Voice Module Test Options
on page 3-5 for more information.)

Chapter 3. Operation
METHODS OF OPERATION
You can control and configure the Quad FXS Voice Module from 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 chapter describes the menu items presented when
managingtheQuadFXSVoiceModuleviatheterminalmenu.
Access the terminal menu using either a VT-100 terminal attached to the TA
850 Base Unit’scontrol port or a Telnet session established through 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 grouped by
functionality. All menu items display in the terminal window. To access the

The Digital 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 signalling sent to the
-
network by the unit. When On-Hook Test is selected, On-Hook signalling is
sent to the network. When Off-Hook Test is selected, Off-Hoo k signalling is
sent to the network. The customer loop is forced On-Hook while this test is
active.
The 1004 Hz - 0dbm0 Tone Gen eration 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:
