CLKG Board Functions

Overview CLKG board provides the required clock for the ZXWN MSCS sys-tem. With the hot active/standby design, the active and standbyCLKG boards are locked to the same reference to implementsmooth changeover. CLKG board filters out jitters to removepossible burrs or jitters of the clock during the changeover.

CLKG boards are configured in the main control shelf. They canaccess the 8K, 2Mbps, or 2MHz clock offered by the SPB, INLPor BITS system, and then provides the 8K_16M (The period is 8K,and the negative pulse bandwidth is 16M) and 16M reference clock



for the main control shelf and other shelves. Figure 37 shows theprocess of clock distribution.

FIGURE 37 CLOCK DISTRIBUTION

Functions CLKG board has the following functions:

Communicating with the control console through the RS485bus.

Allowing to select reference sources in the background or man-ually, including the BITS, line (8 K), GPS, and local (level-2 orlevel-3). Manual switchover can be shielded through software.The sequence for selecting references manually is:

2 Mbit/s1-2 Mbit/s2-2 MHz1-2 MHz2-8 K1-8 K2-8 K3-NULL

Adopting the loose coupling phase-locked system, working infour modes: CATCH, TRACE, HOLD and FREE

The output clock can be level 2 or level 3, implemented bychanging the constant-temperature crystal oscillator and cor-responding software.

Providing 15-channel 16M and 8K_16M clocks to the UIMC.

Being capable of clock lost alarming and deterioration judg-ment of inputted reference.

Being capable of active/standby changeover function withthe hot active/standby design. The active and standby CLKGboards are locked to the same reference to implement smoothchangeover. The CLKG adopts the measure of filtering outphase jitters to remove possible burrs or jitters of the clockduring changeover. Provide such modes as the commandchangeover, manual changeover, fault changeover, and resetchangeover. The Bit Error Ratio (BER) effect on the systemduring maintenance changeover is less than 1%.

The discontinuity between phases of two CLKG boards is lessthan 1/8 unit interval (UI) code element.


Chapter 3 Boards

Providing relatively perfect alarm function, including SRAM fail-ure alarm, constant-temperature trough alarm, reference andoutput clock loss alarm, reference deterioration alarm, refer-ence frequency deviation exceeding standard alarm and phase-locked loop phase detection loss alarm. These alarms facilitateto quickly detect the current working status and failure loca-tion of the clock generating board.

The clock is maintainable. The VCXO provides the frequencymodulation knob to facilitate frequency modulation when theaxis frequency deviates in a certain range due to the aging ofquartz crystal several years later.

Name Explanation



There is one 4-bit DIP switch on the SPB board (T1 mode), namelyS1, as shown in Figure 57.

S1 is used to indicate the long/short-wire status of each chan-nel T1 chip. CPU reads this status, and performs different ini-tializing of the T1 chip according to this status.

The four channels of S1 respectively correspond to the first,second, third and fourth T1 chips, namely, T1s of channels 1to 4, channels 5 to 8, channels 9 to 12, and channels 13 to 16.

S1 switch off (that is, 1 is read out) indicates long wire; switchon (that is, 0 is read out) indicates short wire.



SPB Board Functions

Description SPB board is used for narrowband signaling processing, includingthe HDLC of multi-channel No.7 signaling and the signaling belowMTP3 layer. It transmits the data above MTP3 layer to the homeSMP through the control-plane Ethernet for processing.

It supports E1/T1 mode, and two impedance configurations, 120Ω and 75 Ω. It supports the signaling transfer.

It supports 64K and 2M signaling links.

It provides two-channel external reference 8 KHz clock to the clockboard.

Mechanism SPB board may be used for E1/T1 access or HW access. In theZXWN MSCS, it usually adopts the E1/T1 access mode to accessthe external E1/T1 directly. The signaling processing procedure isshown in Figure 58.

FIGURE 58 SPB E1/T1 ACCESS PROCESSING PROCEDURE

For the uplink channel, the narrowband No.7 signaling accessesthe ZXWN MSCS system through the E1 or T1 interface of theSPB board. The SPB processes MTP layer 1 and 2 signaling, andconverts the processed information to IP packets. Through theIP switching of UIM (intra-shelf switching) or CHUB (inter-shelfswitching), IP packets are distributed to the SMP board for it tocomplete the protocol processing of MTP layer 3 and above.

For the downlink channel, the processing procedure is on the con-trary.

With the E1/T1 access mode (that is, directly accessing the ex-ternal E1/T1), the SPB should be configured with RSPB or RSPB/2rear board.

Alarm System ComponentsDescription The alarm system enables users to learn the faults occurring to

devices at any time. If a device is faulty or runs improperly, itsends alarm information to the alarm server that not only presentsthe current or history alarms but also forwards alarms to the alarmbox in real time. The alarm box generates sounds or lights toprompt the received alarms of different levels and forwards alarminformation to preset mobile phone number if necessary.

Components The alarm system consists of two components, namely the alarmserver (generally it is an OMM server) and the alarm box, as shownin Figure 74.

FIGURE 74 ALARM SYSTEM

The alarm server allows users to determine the levels of alarmsto be forwarded to the alarm box as well as the mobile phonenumber to which the alarm box sends alarm short messages.

The alarm server transfers alarm messages to the alarm boxthrough the TCP/IP protocol. The mobile phone module ofthe alarm box sends alarms to the specified mobile numberthrough short messages.



Alarms are not only presented on the LCD screen of the alarmbox but also prompted by the alarm indicator, alarm serverindicator, and sounds.

Alarm Box FunctionsDescription The alarm box is connected with an alarm server through HUB or

a layer-2 switch. The alarm box presents different levels of alarmdata sent from the server in various ways, for example, on theLCD screen, through indicators, and by generating sounds.

Functions Alarm short message sending: The alarm server can be con-figured to interact with the in-built mobile phone module of thealarm box, enabling the alarm box to send alarm short mes-sages to the specified mobile number of a maintainer. Thealarm box sends alarm short messages based on severity ofalarms to CDMA or GSM subscribers (however, CDMA and GSMcannot be supported simultaneously).

Sound prompt: The in-built speaker produces voice or buzzeralarms to prompt the received alarms and the alarm levels.

Alarm indicator: The four alarm levels are represented by dif-ferent colors, namely, yellow, orange, blue, and red (listedfrom high to low).

Alarm server indicator: The alarm box panel provides 10alarm server indicators representing 10 group of alarm servers(generally it is recommended that one indicator represent oneserver). Each indicator shows the link status and the alarmstatus for a specific group of server servers.

LCD display: The alarm information sent from the alarm serveris displayed on the LCD screen of the alarm box. Moreover, thealarm box menu and keys on the panel are available to config-ure the working parameters, for example, the IP address, UDPport, key tone control, and backlight control.

Remote deployment: An alarm server can be connected toboth local alarm boxes (in the same network section with thealarm server) but also the remote alarm boxes in different net-work sections by configuring routing information in the alarmbox. Remote deployment allows more flexible usages of alarmboxes. For example, the alarm box can be deployed in the of-fice rather than in the equipment room.

Multi-office-in-one: Up to 128 alarm servers can be configuredon an alarm box, and up to 10 groups of alarm servers can besimultaneously connected to an alarm box. The alarm serversmay reside in different network segments, and therefore themulti-office-in-one function is employed together with the re-mote deployment function.

Cross-VLAN alarming: The alarm box can be simultaneouslyconnected to alarm servers from different VLANs. In this sce-nario, a layer-2 switch rather than a layer-3 device is deployedto achieve VLAN isolation, reducing the networking cost.


Chapter 4 Integrated Alarm Box

Network storm detection and alarming: Thresholds can be con-figured to detect the network status and avoid network conges-tion caused by data broadcast.

Group-based alarm acknowledgement: Alarms can be ac-knowledged on a per-group basis as alarm servers can beclassified into groups, and each group of alarm servers isrepresented by an alarm server indicator.

Alarm statistics query: The alarm box can show the statisticsof alarms reported by each alarm server on the LCD screen.

Permanent mute: Alarm prompts can be muted based on thealarm severity.

Remote access: The alarm box supports Telnet-based remoteaccess. Users can telnet the alarm box to configure relevantparameters by using man-machine commands. The alarm boxsupports the configurations concerning alarm servers, routing,VLAN, short message transfer, system time, and so on.

Hygrothermal Sensor Cable

Functions The hygrothermal sensor cable is used to connect the hygrother-mal sensor with End B3 of the environment monitoring transit ca-ble to monitor the ambient temperature and humidity.

In the hygrothermal sensor, the humidity core adopts humidity-sensitive capacitance elements. After linearization processing ofthe single-chip computer, the system outputs frequency signalswithout A/D transfer. It directly collects and processes the hy-grothermal signal value through computer. It is installed withwall-mounted mode, with hidden routing slot at the back of thetransmitter.
