Chapter 1 System Architecture Introduction


Introduction to the Module Function ZXIN10-SSP: It offers the SSF, CCF and CCAF; if no

standalone IP is used, it also offers a part of SRF. It can

trigger IN service according to the CAMEL subscription

information (CSI) or number segment; it accepts the SCP

operations to control the call process; it also offers the

embedded SRF.

ZXIN10-SCP: It is the core of ZXIN10. It offers the SCF and

SDF and can accept the management from the SMP. It

provides the service logic processing program (SLPS)

required for the processing of the IN service and the data

required for offering IN services. In general, the SCP consists

of two parts: SCF and SDF. The SCP and the SSP are

connected through the SS7 network.

ZXIN10-SMP: It offers functions such as access management,

service management (for example, online service loading),

service data management and network management. It

implements network management, service management and

system management in the IN system. It can load/unload

the IN services newly developed and provided, and manage

ongoing services; especially, it can coordinate the requests

from different SCF and SDF for a given service. It can also

manage and modify relevant IN service data and network

data of the IN.

ZXIN10-SCE: It offers functions such as service logic

compilation, service data creation, syntax check, service

simulation execution, service performance test, service

conflict detection, and service creation. It enables the IN to

implement new services quickly, flexibly, and conveniently.

As a component of the IN, the SCE provides the user with a

means to develop services rapidly.

ZXIN10-IP: It offers functions such as DTMF

receiving/sending, message sending/receiving, voice mailbox,

voice synthesizing, and voice recognition; its record

announcement function offers more than three languages for

option. It provides the resources required for the information

exchange between the user and the network. The resources

include user-defined voice announcement, synthetic

language/speech recognition devices, DTMF number receiver,

signal generator, switching matrix connecting users to the

resources, telephone conference bridge and information

distribution bridge. The IP can be connected directly to one

or more SSPs, or to the SS7 network.

ZXC10-IN Network

Overview This chapter provides a general introduction of IN system

network architecture.

This chapter contains the following topics.

Topic Page.

Networking Mode of ZXC10-IN-SCP and ZXC10-IN-SMP 5

ZXC10-SMAP Remote Access Mode 6

Networking Mode of ZXC10-IN-SCP and ZXC10-IN-SMP ZTE WIN equipment ZXIN10-SCP and ZXIN10-SMP can provide

flexible networking modes according to the specific conditions,

There are three types of networking modes, in which, the

connection within the same local network and the connection via

DDN are the primary two types. If the scales of SCP and SMP

are relatively small, the combined mode of ZXC10-SCP and SMP

are adopted for the further saving of the hardware investment.

1. ZXIN10-SCP and ZXIN10-SMP are located in the same LAN.

It is the most common networking mode, featuring lower

hardware cost, sharing a set of equipment such as the

Ethernet switch and router, and faster information interaction.

2. ZXIN10-SCP is connected with ZXIN10-SMP via the DDN

dedicated line.

It is suitable for the case that ZXIN10-SCP and ZXIN10-SMP

cannot be put locally, for example, a set of SMP managing

multiple sets of remote SCPs. The detailed connection figure

of the mode has been shown in the structure diagram of

ZXC10-SCP and ZXC10-SMP and will not be repeated here.

ZXC10-SMAP Remote Access Mode The ZXC10 system networking is fully based on standard TCP/IP

and is implemented via LAN or WAN. The main networking

modes include DDN, ISDN, X. 25, PSTN and access server. They

are described as follows.

1. DDN Mode

DDN mode can be divided into two modes: synchronous DDN

and asynchronous DDN.

For the synchronous DDN mode, a router should be

configured at the SMP end, and normally 64 K synchronous

leased line is adopted. When accessing less than two remote

SMAPs, the CISCO1720 + WIC-2A/S router (two

synchronous interfaces are provided) is used. In case of

more than two remote SMAPs, the CISCO2620 router (at

most one 8-port module can be provided) is recommended.

In case of even more SMAPs, the CISCO3640 (two 8–port

modules can be connected) or the CISCO2620 combined with

E1 module (30 64KDDNs can be provided) is preferred.

Chapter 2 System Architecture Introduction


Each router synchronous port should be connected with the

base-band MODEM. The specific model should be consistent

with the base-band MODEM model in the DDN node machine

of the office. The interface cable model of the router and the

base-band MODEM is V35 or V24 (refer to the base-band

MODEM interface for detail). One DE853 transceiver (product

of DLINK Company) is required for every router to convert

the AUI thick cable port to the RJ45 thin cable port. The

base-band MODEM is connected to the DDN node machine

via the twisted-pair.

2. ISDN Mode

When there are no more than four remote access points, the

SMP center uses 2B + D ISDN router (CISCO2620 + 4-port

ISDN BRI module) or CISCO1720 (only 1-port ISDN BRI

module can be configured). The CISCO1720 can be

configured in the remote SMAP. In case of multiple SMAPs,

multiple ISDN 2B + D routers or CISCO2620 + ISDN-PRI

module can be configured.

3. X.25 Mode

The X.25 mode is similar to the ISDN mode. Select a

machine at remote SMAP as the network gateway, insert an

X.25 network card, and connect such network card with

synchronous frequency band MODEM as the MOTOLAR3265

or ETECH3648 series via the V.24 interface. Connect the

network card with the X.25 network with that MODEM. At the

NM center, one or more X.25 private lines can be used.

However, as the X.25 private line usually has a low rate, only

using one line may cause serious link congestion.

4. PSTN Mode

PSTN mode needs less investment, but has a low speed and

unstable line performance. At the SMP, select a router that

can be connected with multiple asynchronous interfaces. The

CISCO2620, for example, can be connected with a 16-port

module or 32-port module. At the remote SMAP, dial directly

with MODEM. Select the 56K MODEM. The types are

TD3624VDC (AC/DC) and TD3366 (AC).

5. Using ZXIP10-AS Access Server

This mode makes full advantage of the PLMN resources. The

SMAP dials with the MODEM to access from the local PSTN,

while the toll access runs by way of the PLMN. The detailed

connections are: SMAP-MODEM-PSTN (local) –GMSC-TMSC-

AS-SMP.
