network to business.
1+1 Optical Redundancy Backup: Protection of dual optical interface
available to ensure that business will not be interrupted when one pair of
optical fibres is confronted with failure. Supporting hot add/drop of optical
interface, and fulfil switching without error code during hot add/drop.
◆Flexible Configuration: 4/8/12/16E1 optical multiplexers and
multiservice interfaces are derivable from main system board and
different functional modules, to meet different user requirements and
customizations.
◆Various Functional Modules: User interface modules (N×64K V.35,
FV.35, FXO/FXS, E/M, RS232/RS485, and etc.), order wire module,
network management module (RS232, and Ethernet Interface, etc.),
and alarm output terminal module, etc. available.
2. 3. Operating Principles
T
Th he e
AMX32FE adopts plug-in board structure and can be
functionally divided into five general parts, including:
A. Compound unit of 4/8/12/16-channel E1 or V.35
B. Optical interface
C. Order wire unit
D. Network management unit
E. Secondary power supply module

User Manual Access Multiplexer with Fast Ethernet

A, B and E are the three basic components. Unit A is used for
completing reversible conversion from 4/8/12/16 2048kbit/s signals to
laser signals. The function of Unit B is to perform framing and deframing
of photoelectric signals and E3/E6 optical switch. Unit C and Unit D are
used for playing auxiliary functions.
The features of every unit are given as follows:
4/8/12/16 Compound Unit’s core circuit is composed of one
large-scale ASIC circuit and a few peripheral devices. This circuit
integrates 4/8/12/16 2048kbit/s HDB3 signals from switch or sent out by
PCM into one NRZ digital stream signal, decomposes NRZ signal of the
opposite terminal into eight 2048k signals synchronously and outputs
them through drive circuit in the end. This unit compounds NRZ signals,
order wire services and alarms, then encodes and output NRZ signals to
drive laser, and achieves the reverse process for the above mentioned
part at the same time. It can be plugged in 4/8/12/16 channels of E1
plug-in board, V.35 board or voice board etc. according to the actual user
requirements.
Optical Interface Unit is to achieve dual optical interface of 1+1
redundancy backup; priority-level switch and mandatory switch of
active/standby optical path; and so on.
Switching mode for dual optical interface: Dual transmission with
optimal reception;
Switching time for optical pass: ≤ 50ms;
Type of optical pass: One active and one standby (the active pass is
in operation when it’s normal, and the active pass switches to standby
pass when it is confronted with switching alarm levels such as OPL, SYL,
E3, and E6; The operation will finally return to the active pass after a

certain period of time when active pass is resumed to normal condition);
When the equipment is started, it is preferential to have both local
end and remote end operating with the A optical interface.
ALS (Automatic Laser Shutdown/Automatic Laser Reduction)
function: When a fiber disconnection in this optical pass is detected, the
average output power at the optical transmitting end is reduced by more
than 20dB, and it resumes to normal status when optical fiber is
recovered.
The optical interface applies an optical transmitting/receiving
integrated module of impact structure. It features high-power
transmission, high-sensitivity receiving and independent transmission
and receiving. The new version supports hot plugging/swap of optical
interface. In the case that one optical interface runs into trouble, the fault
optical interface board can be drawn out online and replaced with a new
one.
Network management Unit is designed to control all settings on the
control panel and to realize communications between multiplexer and
computer. The unit can send commands (such as alarm-off, remote
bypass loop-back and so on) to nodes through computer. Users can
directly query and set the status of a pair of devices with Hyper Terminal
software via RS232 crosswire. NM-ETH interface (10/100M
auto-negotiating, to be configured) can be directly connected with a
computer via a crosswire or with a HUB via a straight-through wire to fulfill
management. It can realize ALS (Automatic Laser Shutdown/Automatic
Laser Reduction) to prevent personnel from fiber injury. The user can
select network management functions according to its actual
requirements.

Secondary Power Supply
is a power supply module with function of
over-current and over-voltage protection. It can be used to fulfill
conversion from DC-48V to +5V or from AC220V to DC-48V or +5V.
Users can either choose to use DC-48V power supply alone or apply
DC-48V and AC220V as mutual backup power supplies at the same time.
It supports hot swap of power supply.
