One multi-shelf system must be configured with one pair of CHUB boards, which adopt 1+1 active/standby working mode

CLKG CLKG

One set of system must be configured with one pair of CLKG boards, which adopt 1+1 active/standby working mode.

The CLKG boards are generally configured in the circuit switching shelf. When there is no circuit switching shelf, they are configured in the control shelf


Overview Configuration


The rule for inserting boards to the slots in the control shelf is as follows:

The slots 9 and 10 are the main control slots, where only the UIMC board can be inserted. These two slots are used to exchange information between boards and implement cascading with CHUB.

The slots 1~8 and 11~12 are common slots. The OMP board is fixedly inserted to the slots 11 and 12, and the SMP and the SIPI boards are inserted to other slots.

The slots 15 and 16 are control and switching center slots, where CHUB boards are inserted.

The slots 13 and 14 are clock slots, where Clock Generator Boards (CLKG) or SMP boards can be inserted.

BCTC is used to bear signaling processing module and all main control modules. It transits and processes media streams of control plane. Also, BCTC forms system distribution processing platform in multi-shelf equipment.

Figure 17 shows arrangements of modules in two layers of control shelf.

Following is the description for these modules.

SIPIs in Slots 1 and 2 are used for concentrated access of Mc interface.

SMP and OMP are the communication control centers. They use the same hardware: MPx86 module. Quantity of SMP modules depends on the configuration requirement. OMPs in Slots 11 and 12 offer the OMC function. SMPs offer functions such as call control and processing H.248 signaling. SMP implements call control and H.248 signaling processing. OMP module provides Ethernet interface from operation and maintenance center (OMC) to the background.

The interface on RGIM1 is described as follows:


Backboard Interface Description


8KOUT/DEBUG-232 (RJ45 interface): used to output the 8K system clock to the UIM board, and provide the reference clock for the boards in the shelf. In addition, this interface can be used for debugging, and does not provide service functions in this case.

Strictly observe operation regulations to prevent board from electrostatic damage.

Clock Generator Board (CLKG)

CLKG is clock generator of ZXWN MGW system. CLKG has active/standby mode. Active and standby CLKG boards locks to same reference to implement smooth changeover. CLKG adopts a measure to filter out jitters to remove possible burrs or jitters of the clock during changeover. CLKG communicates with main processing unit through RS485. Also, it uses clock reference 8KHz frame synchronizing signal from trunk DTEC or SPB, or 2MHz/2Mbits signal from BITS system, or 8K (PP2S, 16CHIP) signal from GPSTM, or 8K clock signal from UIM as the local clock reference for synchronizing with upper-level office clock. For input reference, CLKG can provide an alarm signal for reference loss, and can also perform deterioration judgment for reference.

Following are functions of CLKG board:

Communicate with control console through RS485 bus.

Allow selecting reference sources in the background or manually, including BITS, line (8K), GPS, local (level 2 or level 3); manual changeover can be screened by software; the sequence for selecting references manually:

2Mbits1--2Mbits2--2MHz1--2MHz2--8K1--8K2--8K3-NULL

Adopt loose coupling phase-locked system, working in 4 modes: CATCH, TRACE, HOLD and FREE.

Output clock can be stratum 2 or stratum 3, implemented by changing constant temperature through crystal oscillator and software.

Provide fifteen 16.384M, 8K and PP2S clocks to UIM.

Capable of clock loss alarming and determining judgment for input reference.

Active and standby changeover, including command changeover, manual changeover, fault changeover and reset changeover modes; BER effect on the system during maintenance changeover is less than 1%.

Discontinuity between phases of two CLKG boards is less than 1/8 UI code element.

Provide relative complete alarm function, including SRAM failure alarm, constant temperature trough alarm, reference

The RCKG1 and RCKG2 have totally 5 CLKOUT interfaces, which mean that the CLKG board can provide at most 15 groups of 8K/16M/PP2S system clock output interfaces.


Interface Description


8KIN1 and 8KIN2 (RJ45 interface): It is the input interface of the 8K reference clock, which can introduce the 8K reference clock provided by DTEC, SPB, APBE, SDTEC, GPS and other boards.

2Mbps/2MHz (DB9 interface): It can introduce two lines of 2Mbps or 2MHz clock reference.

PP2S/16CHIP (RJ45 interface): Provides the input interface of the P2S/16CHIP reference clock of the GPS.

Therefore, the CLKG board can provide the following external interfaces:

15 groups of 8K/16M/PP2S system clock output interfaces;

2 groups of input interfaces of the 8K reference clock provided by DTEC, SPB, APBE, SDTEC, GPS and other boards;

2 groups of 2Mbps and 2MHz reference clock input interfaces;

1 group of P2S/16CHIP reference input interfaces of the GPS module.


Inter-Working Function Board (IWFB)

IWFB offers circuit switching data bearer service for transparent/non-transparent, synchronous or asynchronous data services and nontransparent fax service.

IWFB processes circuit-domain data service. Uplink data may come from HW interface or Ethernet interface, depending on system configuration. If uplink data comes from HW interface, DSP processes the data link protocol of wireless network, implements rate adaptation, and converts other protocols. For modem/fax service, after processing data, the DSP sends it to main control processor MPC8250 (data can also directly sent to MPC8250 without passing through DSP); MPC8250 then sends data to M80310 for data/fax modem processing; after modulation, 64 Kbps data is generated and then sent to the PSTN through DTU. For ISDN service, after terminating the RLP, CPU sends data again to DSP; DSP then adapts data into ISDN service flow generates ISDN service flow and transfers it to the ISDN through DTB/SDTB.

IWFB boards have the following external interfaces.

Backplane can connect up to 4 pairs of 8 MHz HW cables to resource processing part on the backplane through TDM switching network. In this way, backplane ensures the flexible allocation of timeslots to facilitate the future expansion. Data flow in TDM side synchronizes with 8 kHz and 16 MHz clock from the UIM.

Backplane connects with one 10/100M control flow Ethernet for downloading CPU and DSP versions and modem firmware, connecting voice channels, and transferring signal flow to be processed inside backplane and the commands and parameters sent by system for controlling, configuring, maintaining, and managing the backplane.

Backplane connects with one 10/100M media flow control Ethernet for bearing circuit-domain data services from the switching Ethernet.

IWFB reserves one set of RS-485 bus for connecting with UIM.

IWFB retrieves cabinet number, shelf number, and slot number from backplane.

IWFB sends its reset report to UIM and accepts the hardware reset signal from the UIM.

There are 12 DIP switches on DTB/DTEC.

Eight 4-digit DIP switches (S1-S6, S9, and S12) are used to select the matching impedance of each E1 channel: 75 ohm or 120 ohm.

If DIP switch is “ON”, the line impedance is 75 ohm. And if DIP switch is OFF”, the line impedance is 120 ohm.

Two 4-digit DIP switches (S7 and S8) indicate the receiving matching impedance of each E1 chip for the CPU.

If DIP switch is “ON”, it indicates that the matching impedance of the corresponding E1 is 75 ohm. And if DIP switch is “OFF”, it indicates that the matching impedance of corresponding E1 is 120 ohm.

Each DIP switch corresponds to one E1 chip: S7 corresponds to E1 Chips 1–4 (E1 Channels 1–16); S8 corresponds to E1 Chips 5–8 (E1 Channels 17–32). CPU retrieves the state and initializes the E1 chip according to the state.

Two 4-digit DIP switches (S10 and S11) indicate the long/short haul state of each E1 chip for the CPU.

If DIP switch is “ON”, it indicates that the corresponding E1 chip (four E1 channels) works in the “SHORT HAUL” mode. If DIP switch is “OFF”, it indicates that the corresponding E1 chip works in “LONG HAUL” mode.




Each DIP switch corresponds to one E1 chip: S10 corresponds to E1 Chips 1–4 (E1 Channels 1–16); S11 corresponds to E1 Chips 5–8 (E1 Channels 17–32). CPU retrieves the state and initializes E1 chip according to the state.

It provides one 155 Mbps STM-1 interface.

It is compatible with E1 and T1.

It provides AU pointer processing, mapping and de-mapping functions for the STM-1 signal.

It supports CAS and CCS.

It provides SDH network management function through the TDM.

It provides sixteen 8M HW to provide adaptation for the UIM.

It outputs two channels of differential 8K synchronization clock signal as the reference clock of the clock board.

It provides one 100M Ethernet interface for communicating with the UIM and transferring management information, control information, software version, and so on.

It provides functions such as remote reset and load and hardware WATCHDOG.

It provides active/standby communication and changeover functions.

Figure 90 shows the working principle of the SDTB.


Overview Functions Working Principle


F I G U R E 90 SDTB B O A R D W O R K I N G P R I N C I P L E

Circuitry of SDTB includes following parts:

CPU subsystem

155.52 MHz optical/electrical interface circuit

Switching circuit

Overhead processing circuit

Mapping and framing circuit

Data received from STM-1 optical interface is sent to the overhead processing circuit. Overhead processing circuit performs operations such as clock phase-locking and synthesis, section overhead processing, parallel-to-serial conversion, channel overhead processing and pointer processing on the data. Then the overhead processing sends data to the mapping and framing circuit for de-mapping. After that, data sends to framer and then sent to the backplane through switching circuit as 8MHW. If the EC function is needed, 8M HW is sent by the switching circuit and then sent to the backplane through the EC circuit. Framer can process CAS, which is then retrieved by the CPU. Mapping and framing circuit does not process CCS. Communication link data of the CPU is sent to the UIM through HDLC. Similarly, the switching circuit retrieves the communication link data from 8MHW of the backplane, and then sends the data through HDLC to the CPU for processing. Voice channel is sent to the mapping and framing circuit as 8 MHz. Mapping and framing circuit maps the voice channel and then sends it to the overhead processing circuit.

Glossary

3G refers to next generation of mobile communication systems. These offer enhanced services, such as multimedia and video. Main 3G technologies include UMTS and CDMA2000.

3GPP was formed in December 1998 as a collaboration agreement bringing together a number of telecommunication standards bodies. These standards bodies are referred to as Organizational Partners. Aim of 3GPP was to produce globally applicable technical specifications for third generation mobile systems based on evolved GSM Core Networks and the radio access technology Universal Terrestrial Radio Access (UTRAN).

3GPP2 is a sister project to 3GPP and is a collaboration agreement regarding third generation mobile networks. It is comprised of five Standards Development Organizations similar to Organizational Partners in 3GPP. 3GPP2 mainly deals with the following five areas: A-interface system, CDMA2000, American National Standards Institute-41 (ANSI-41), wireless packet data inter-working, and services & systems aspects.

An Access Point is a network device which provides the point of interconnection between wireless station (laptop computer, PDA) and wired network.

Bearer Service is a type of telecommunication service that provides the capability for transmission of signals between access points.

Broadband in radio systems identifies a type of communication channel capable of carrying a large portion of electromagnetic spectrum. It may also be applied to fixed communication systems when referring to bearers capable of carrying high volumes of traffic.

A client server application protocol using well known ports 20 and 21. It uses the services of Transmission Control Protocol (TCP) to provide reliability in the transfer of data files between network nodes. FTP was first defined as a standard in Request for Comments (RFC 959).

Gigabit Ethernet (GE) is the Ethernet standard offering Gigabit services and typically employs fibre. This technology has been used for backbone networks and desktops for high end servers and intensive graphical applications.

A Handoff, or Handover, is the process in which a cellular phone is handed from one cell to the next in order to maintain a radio connection with the network

International Mobile Equipment Identity is a unique identifier allocated to each Mobile Equipment (ME). It consists of a Type Approval Code (TAC), a Final Assembly Code, Serial Number (SNR) and a Spare Digit.

International Mobile Subscriber Identity is a unique identifier allocated to each mobile subscriber in a GSM and UMTS network. It consists of a Mobile Country Code (MCC), a Mobile Network Code (MNC) and a Mobile Station Identification Number (MSIN).

ISDN User Part is part of the SS7 protocol layer and used in setting up, management, and release of trunks that carry voice and data between calling and called parties.

This is the interface in UMTS which links the Radio Network Controller with MSC Server.

This is the interface in UMTS which links the RNC with SGSN.

Location Area Identity uniquely identifies a Location Area (LA) within any Public Land Mobile Network (PLMN). It is comprised of the Mobile Country Code (MCC), Mobile Network Code (MNC) and the Location Area Code (LAC).

MAC address refers to hardware address and uniquely identifies a device within a defined network area.

Mobile Station ISDN (MSISDN) Number is the standard international telephone number used to identify a given subscriber. MSISDN is based on the International Telecommunications Union-Telecommunication Standardization Sector (ITU-T) E.164 standard.

Mobile Station Roaming Number is an E.164 defined telephone number used to route telephone calls in a mobile network from a Gateway Mobile Switching Centre (GMSC) to the target MSC.

Message Transfer Part forms part of the SS7 protocol stack and provides reliable routing usually within a network.

A set of procedures, software, equipment etc in order to keep a network operating in an efficient manner. ITU-T have developed a series of standards for Network Management which are referred to as the Telecommunication Management Network (TMN). This sub-divides Network Management into the following five categories; Fault, Configuration, Performance, Accounting and Security.

Node B is the function within the UMTS network that provides physical radio link between User Equipment (UE) and the network.

A physical channel supports physical media, usually in an encoded format. This may be pulses of light, a modulated voltage or radio waves.

Conceptual model of layered architecture of communication protocols in which, layers within a station are represented in hierarchical order. Each layer in the protocol stack is defined in generic terms describing functionality and mode of operation.

Glossary

Performance of a communications channel or system is usually expressed in terms of Quality of Service (QoS). Depending upon the communication system, QoS may relate to service performance, Signal to Noise Ratio (SNR), Bit Error Ratio (BER), maximum and mean throughput rate, reliably, priority and other factors specific to each service.

Radio Access Network (RAN) performs the radio functionality of network, as well providing connection to Core Network. RAN typically includes a controller Radio Network Controller (RNC) in 3GPP and BSC in 3GPP2 and several transmitter/receivers Node B in 3GPP, BTS in 3GPP2.

Radio Access Network Application Part (RANAP) is used in a UMTS system on the Iu interface. It is responsible for function including setting up of a Radio Access Bearer (RAB) between the Core Network and RNC.

Signalling Connection Control Part is used to provide a means for the transfer of messages between any two signalling points in the same or different SS7 networks.

Streaming Control Transmission Protocol (SCTP) is a reliable transport protocol operating on top of IP. It provides acknowledged error free non duplicated transfer of data. STCP also detects data corruption, loss of data and duplication of data by using checksums and sequence numbers.

A Signaling Gateway is used to support the transport of signalling traffic received from one network and passed into another network.

In order to ensure subscriber identity confidentiality VLR and SGSN may allocate Temporary Mobile Subscriber Identities (TMSI) to visiting mobile subscribers. VLR and SGSN must be capable of correlating an allocated TMSI with IMSI of MS to which it is allocated. A MS may be allocated two TMSI, one for services provided through VLR, and the other known as the Packet TMSI (P-TMSI) services provided through the SGSN.

Telephone User Part was an earlier implementation of SS7 that did not allow for data type applications, hence the introduction of ISDN User Part (ISUP).

A 3G mobile communications system which provides an enhanced range of multimedia services. UMTS will speed convergence between telecommunications, IT, media and content industries to deliver new services and create fresh revenue generating opportunities. UMTS will deliver low cost, high capacity mobile communications offering data rates as high as 2Mbps under stationary conditions with global roaming and other advanced capabilities. The specifications defining UMTS are formulated by 3GPP.

The identifier in ATM cell header that identifies to which virtual channel the cell belongs.
