Warr anty Warnings
!
WARNING:
When inserting modules into the chassis, slide them gently, not forcefully. Excessive force may cause the modules to be seated improperly in
the chassis, and result in possible damage to the module or the chassis.
Install or remove modules one at a time. Doing this aids in preventing
the PSAX system from indicating any erroneous failure messages, and
allows the PSAX system time to reinitialize and display the accurate configuration of the module that is inserted.
!
CAUTION:
Modifying or tampering with PSAX chassis components may void your
warranty. Any modification to this equipment not expressly authorized
by Lucent Technologies may void your granted authority to operate such
equipment.
!
CAUTION:
Shipping the chassis with removable I/O, server, or CPU modules
installed may cause damage to the chassis and the modules. Damage to
any of the components in the system resulting from shipping the chassis
with removable modules installed will void your warranty.
!
DANGER:
Interface lines connected to the 4-Port Voice 2-Wire Office module
(model 20N32) that exit the building premises must be connected to telecommunication devices that provide primary and secondary protection.
Safety Information
When installing and operating the 4-Port Voice 2-W ire Office module, follow
the safety guidelines provided in the PacketStarway Safety Guidelines, which accompanies this product, to help prevent serious
personal injury and damage to the module. Please read all warnings and
instructions supplied before beginning installation or configuration of this
module. In addition to the general safety information provided, you should
also refer to the text in the PacketStar PSAX installation guides for other
important safety information and procedures.

protection for two groups of four or six multiport DS3, STS-1e, or E3 modules is provided via an N:1 protection scheme using rear access line interface
modules. The protection module provides backup so that on the failure of
any one of the modules in a group, traffic is maintained. A single PSAX 4500
system at the edge of the carrier network can transition traffic from a large
number of network customers over high-speed DS1/E1 IMA, DS3/E3, OC-3,
OC-3c/STM-4c, and OC-12c/STM-4c trunks into the ATM core, managing
the whole quickly and efficiently, down to the individual permanent virtual
circuit.

Title: PacketStar
The 4-Port Voice 2-Wire Office module (20N32) provides support for the
office (central office or PABX switch) end of a two-wire analog telephone
line. This allows a voice loop from a voice switch to be connected directly to a
Multiservice Media Gateway system over an ATM network to a distant telephone or other analog device. The coding translation supported by this module is µ-law to µ-law only.
The module has three types of light-emitting diode (LED) indicators:
ACTIVE, FAIL, and LOS (loss of signal). On the faceplate, each port has a LOS
LED which turns on when the port goes off-hook. It also flashes in synchronization with an incoming ringing signal to the port.

4-Port Voice 2-Wire Office Module
4-Port Voice 2-Wire Office Module
This module is typically configured with an 8-Port Voice 2-Wire Station module via a PVC connecti on to e nable a f orei gn exchange (FXO) v oice service to
be transmitted across an ATM network. With FXO service, the voice switch
provides dial tone, ringing, and digit translation, which are not provided by
the A TM network.
Module Placement Requirements
You may install the 4-Port Voice 2-Wire Office module in any I/O slot in any
PSAX Multiservice Media Gateway chassis intended to contain I/O or server
modules. In typical applications, this module is used with the 8-Port 2-Wire
Station module.
Hardware Features
The 4-Port Voice 2-Wire Office module supports these hardware features:
• Number of ports: 4
• Connector type: RJ-11
• Ringing frequency: 20 Hz
• Termination impedance: 600 Ohms
• Signaling: dual tone multi-frequency (DTMF)
