FIGURE 1 IAD LOCATION IN NGN SIMPLE ARCHITECTURE

IAD Product With the development of network technology, integration oftraditional telecommunication and data communication becomesthe tendency. SoftSwitch(SS) technology interconnects betweenPSTNnetwork and grouping switching data network smartly andefficiently, and help PSTN evolve to IP network smoothly.

Facing individuals and enterprises, IAD is the subscriber access de-vice in SS network architecture, which accesses terminal devices(such as PC, telephone and electrograph) to grouping switchingnetwork. IAD provides subscribers with more service by transmit-ting data service transparently and performing VoIP disposal onvoice.

ZTE has a wide variety of IAD products, such as I508, I524, I504and I508C, etc. These products meet different requirements of di-versified networking and subscriber types. Here take IAD productI508A for example in Figure 2.

ProtocolIntroduction

H248 protocol is applied in the interconnection between SS controldevice and IAD, which belongs to the interface protocol betweenMGC and MG.

H.248/Megaco (Media Gateway Control Protocol), called H.248protocol in short, is non-peer a media gateway control protocolstipulated by IETF and ITU-T. H.248 is applied in the telecom-munications between MGC and MG, and its main functions are



to establish a fine service bearing connection model to separatethe connection between calling and bearing, besides, it also canrealize the service interconnection between network and PSTNnetwork by managing TG, AG and IAD, etc.

H248 protocol is intended for controlling and supervising the bear-ing connection behavior of MG. As a result, the primary issues areto abstract and describe MG interior objects, that’s why H.248 putsforward the GW connection model conception.

Connection models are the logical entities or objects in MG con-trolled by MGC. It is the content core of the messages betweenMGC and MG. MGC controls the connection model on MG by com-mands while MG reports various information of the connectionmodel, including status, parameters and ability. Basic architectureof model includes: termination and context, as shown in Figure 3.

FIGURE 3 H.248 CONNECTION MODEL EXAMPLE

1. Termination is a kind of logical entity which can send and re-ceive one or several kinds of media streams.

Termination comprises lots of attribute descriptions which com-bine to a group of descriptive symbols in commands, such ascorrelative media stream parameters, bearing parameters, andpossibly-included Modern, etc.

Termination corresponds to a physical entity or a virtual entity.Once encased in the gateway, physical termination can existpermanently (so-called semi-permanent termination). Physi-cal termination can be a PSTN trunk interface on TG, commontelephone interface or PBX interface on AG. Meanwhile, virtualtermination (temporary termination) corresponds to informa-tion stream, such as RTP voice stream affiliated with calls, oncea call is terminated, this voice stream die out.

In actual applications, after establishing a termination, this ter-mination will be allocated with a unique Termination ID to iden-tify termination in MG.



2. Made up of a group of terminations, context represents therelations between a group of terminations.

One context can include multiple terminations. Maximum ter-mination number is varied in context in compliance with dif-ferent MG service characters. One context must comprise oneterminal at least; meanwhile, one terminal can only belong toone context at a time. If a context contains more than 2 ter-minals, it will describe topological structure and other mediamixed/switched parameters.

Steps 1. In the Data Configure interface, select Service Manage(S)> TID NAME Configuration(I).

The TID NAME Configuration window pops up as shown inFigure 33.

FIGURE 33 TID NAME CONFIGURATION WINDOW

2. Click the Add(A) button, and select Add TID Name from thepop-up menu.

The Add TID Name window pops up as shown in Figure 34.

3. Configure related parameters are listed in Table 20.

TABLE 20 TID PARAMETERS ILLUSTRATION


Node No. The IAD node number

MG Resource

NumberLength

Fill in according to the added TID NAME number,if the number is less than 10, fill in AG5890 withnumber length 1; if the number is less than 100,fill in AG589 with number length 2.

MG ResourceType

Select 4-Subscriber circuit indexed by NOC.NOC indicates an index.

Number Corresponds to the subscriber digit number (DN) inthe IAD configuration. The subsequent subscriberDNs increase on the basis of this item according toStart Number and End Number.

Network Type Select it according to actual conditions. This itemshould be consistent with that in the IAD zone con-figuration.

Area Code Area number where the IAD zone is.

Start Number Start number of the last digit of this resource.

End Number End number of the last digit of this resource.

NumberLength

Change the last-digit auto-numbering length ofthis resource, for example, the number inFigure34 indicates to add RTP resource number fromAG58900 to AG58902.

Resource No. -

Show DefaultValue

Enables the default configuration (default startnumber, end number and length)



4. Click the OK button to finish configuration. Repeat step 2 toadd a new RTP type, as shown in Figure 35. Related parame-ters are listed in Table 21.

FIGURE 35 ADDING A RTP TIDNAME OF THE IAD

TABLE 21 ADD TID NAME (2)


Node No. The IAD node number

MG ResourceName

NumberLength

Set it according to the number of TIDNAMEs.For example, to add TIDNAMEs with the numbersmaller than 10, then set MG Resource Name toRTP/0000, and set Number Length to 1; to addTIDNAMEs with the number not greater than 100,set MG Resource Name to RTP/000, and setNumber Length to 2.

MG ResourceType

Select 13-RTP.

Start Number

End Number

NumberLength

Fix the S/N of RTP port by Start Number, EndNumber and Number Length. For example, ifstart number is 0, end number is 2 and numberlength is 1, then add TIDNAME name fromRTP/00000 to RTP/00002. TID NAME number ofRTP style must be identical with subscriber type.

Resource No. ID of the terminal using the one-number-multiple-terminal service, valid for H.263 only.

Show DefaultValue

Uses the default start number, end number andnumber length.




Caution:

For IAD device interconnection of MGCP protocol, it’s only nec-essary to configure MG Resource Type to 4-subscriber circuitindexed by NOC, NOC indicates the TIDNAME of index, MGresource adopts alln/0 to alln/9.

END OF STEPS

Result Configure TID NAME successfully.

Checking the Interconnection Result

Introduction Check whether both interconnection parties can communicate witheach other and carry on the business successfully after configuringinterconnection data.

Physical Check In the NetNumenN31 interface, right-click the SS NE, and selectDiagnose Management in the shortcut menu, then select In-stant Test > Net Detect in the popup interface, finally click theDetect button.

Result: Accessibility of physical connection is as shown in Figure36.

FIGURE 36 ACCESSIBILITY OF PHYSICAL CONNECTION

Command Mode Right-click the SS NE, and select Command Line Terminal to en-ter CLI Console interface, enter command 5004:Module num-



ber to query TG node status (Module number=the IAS node’s SPCLSQ-2), if the reply contains: MG STATE is IN SERVICE, Figure37 indicates the interconnection is successful.
