Power monitor unit

Built-in monitor card in the power distribution unit

Environmental monitoring card

The environmental monitoring card includes the H303ESC and H304ESC. The

following takes the H304ESC card as the example to introduce the functions and

features. Note that although the H303ESC and H304ESC cards have the same basic

features, the H304ESC card has no humidity monitoring function.

The H304ESC communicates with the control card through serial ports. The

H304ESC can monitor 8 analog parameters and 22 digital parameters, and monitor

multiple types of intelligent power supply through serial ports. Detailed functions of

the H304ESC are as follows:

Analog parameter monitor: The H304ESC has built-in temperature and

humidity sensors, which monitor the temperature and humidity in the cabinet. It

also provides 3 analog signal interfaces to connect external analog sensors. For

each monitor signal, you can set the alarm upper/lower limits and the sensor

properties.

Digital parameter monitor: The H304ESC monitors the power distribution unit

and access control. It also provides 13 digital sensor interfaces to connect

various external digital sensors. The external sensor uses a 12V or 24V power

supply. You can define the sensor signal name and set the alarm level

dynamically.

Fan monitor: The H304ESC provides the power supply interfaces for the

cabinet’s fan frame and controls the fan switch with respect to the temperature.

Moreover, it can monitor the running status of each fan through the fan monitor

card.

Intelligent control output interface: The H304ESC provides two control

interfaces. Through these two interfaces, the H304ESC can receive the

commands from the NMS and control the connection with external intelligent

equipment.

Intelligent power supply monitor: The H304ESC can monitor and manage

multiple types of intelligent power supplies through its serial port.

Environmental monitoring box

The environmental monitoring box consists of H304ESC, H601ESBB and H601ESFB.

The box has following functions:

Monitors various environmental parameters, such as temperature, humidity,

smoke, water, door status and main distribution frame (MDF).

Provides multiple types of extended monitor interfaces.

Monitors the power system when connected to the monitor unit of the GEPS4845

power module.

Power monitor unit

The power monitor unit includes PSM-B9 and PSM-B5. The unit has following

functions:

Monitors the power supply in real time.

Automatically manage the battery based on the configuration.

Obtains the running parameter values of the power supply system.

Configures and controls the power supply system.

Built-in monitor card in the power distribution unit

The built-in monitor card can monitor the following parameters:

Lightning protection components

Input voltage

Output voltage

Shunt protection switch

Temperature and humidity in the power distribution unit

The card provides eight digital monitor interfaces to detect the environment

parameters, such as water, access control and MDF.

1.4 Frames

There are two types of frames. One is a front-access frame and the other is the rear-

access frame. This section describes the frame types.

1.4.1 Rear-Access Frames

The HABA frame is the master frame of the rear-access UA5000, which stands at a

height of 16 U.

The HABA frame provides 36 slots, of which 30 are available for line cards. However,

if you are using the AIUB and TSSB, you must insert the AIUB cards and the TSSB

card in the positions shown in Figure 1-1. The remaining six slots are reserved for

other types of cards.

You can insert narrowband line cards and broadband line cards in any of the 30 line

card slots.

The two narrowband control cards and the two broadband control cards in the frame

support backup in the event of a primary controller failure.

The HABA frame can use a minimum of one and a maximum of two PWX cards. The

two PWX cards in the frame share the power supply load, and if one PWX fails, the

other has the capacity to dynamically provide the necessary power.

Figure 1-1 shows the layout of the HABA frame.

1.4.2 Front-Access Frames

There are four models of rear-access frames: HABD (master frame), HABE (slave

frame) and HABF (extended frame).

I. HABD frame

The HABD frame is the master frame of the front-access UA5000, which stands at a

height of 10 U. The HABD frame can be subtended with multiple slave frames, and

the HABD frame can aggregate the services from the subordinate frames.

The HABD provides 18 slots, of which 12 are available for line cards. However, if you

are using the AIUB and TSSB, you must insert the AIUB cards and the TSSB card in

the positions shown in Figure 1-1. The remaining 6 slots are for other types of cards.

You can insert narrowband line cards and broadband line cards in any of the 12 line

card slots.

The two narrowband control cards and the two broadband control cards in the frame

support backup in the event of a primary controller failure.

The HABD frame can use a minimum of one and a maximum of two PWX cards. The

II. HABE frame

The HABE frame is the slave frame of the front-access UA5000, which stands at a

height of 10 U.

The HABE frame operates under the control of the HABD frame. The HABE frame

can be subtended with the HABF frame.

The HABE frame provides 18 slots, of which 14 are reserved for line cards and 4 for

other types of cards. You can insert narrowband line cards and broadband line cards

as desired.

The two broadband control cards in the frame support backup in the event of a

primary controller failure. The HABE frame does not have narrowband control cards.

The narrowband line cards in the frame are controlled by the narrowband control card

in the HABD frame.

The HABE frame can use a minimum of one and a maximum of two PWX cards. The

Figure 1-1 Hardware structure of the master frame

The master frame is the control core of the UA5000. The frame can control the

subtended slave and extended frames.

The master frame switches, aggregates and transmits services upstream for master

frame, slave frame and extended frame.

The master frame can be subtended with slave frames and extended frames to share

resources between frames. The frame can also be connected with subscriber lines.

The service handling process of the UA5000 is as follows:

The narrowband line cards send services to the narrowband control card (PVU8,

PVU4 and PVM) through the TDM bus. After carrying out the protocol processing

and time slot crossing, the PVU8/PVU4/PVM forwards these services upstream

through the NNI.

The broadband line cards send services to the broadband control card

(APMB/IPMB) through the high speed bus, and the APMB/IMPB aggregates and

forwards these services upstream through the NNI.

The line card management of the UA5000 is as follows:

The narrowband control card manages narrowband line cards and test card

(TSS) in this frame, the slave and extended frames.

The broadband control card manages the broadband line cards, interface cards

and test card in this frame, the slave and extended frames.


12



When the UA5000 acts as a component of the NGN, the PVM converts the TDM

signals of all narrowband service data into IP packets and sends the IP packets to the

IPMB card. The IPMB then forwards these packets upstream to the IP network along

with the broadband services.

The TSSB card tests the line cards, and reports the test results to the control cards.

Figure 1-1 Hardware structure of the slave frame

The slave frame is typically designated as a subscriber access unit, which can also

extend its bus to the extended frame to enable sharing between frame resources.

Services from the narrowband line cards are converged by the TDM bus, and

forwarded upstream to the master frame through the conversion card or backplane.

Services from the broadband line cards are converged by the intra-frame high speed

bus. After being processed by the APSB card, the services are forwarded upstream to

the master frame through conversion cards or backplane cables.

III. Extended frame

The extended frame operates as a subscriber access unit. Services from the

Services from the broadband line cards are converged by the intra-frame high speed

bus, and forwarded upstream to the master frame through the conversion card or

backplane.
