3. Key questions

3.1. What application software is used in MN?

3.2. What modes of work can be used? What is this separation intended for?

3.3. What are the main commands used during the work with the application software of MN?

4. Hometask

4.1. Give answers to the key questions in the written form.

4.2. Study the designation and basic possibilities of the application software of MN.

5. Laboratory task

5.1. Turn the computer with software of MN.

5.2. Run MN Login. Sequentially run every program for the node ics (6000). Study all available menus for administration.

5.3. Open the application CMG. Change the access mode on the Read/Write, compare with the previous mode and mark what functions have become available.

5.4. Study the possibilities of creation of new objects (Insert), modifying (Update), deleting (Delete) and applying (Apply) changes. For acquaintance use the table CMG -> Subscriber -> Subscriber.

5.5. Consider the possibilities of search of the required information with the help of the combination Query and Retrieve. To perform the search the set search parameters must fully correspond to the data in the table. For example, for the search of all subscribers with Feature Set: Analog Public, it is necessary after the query to input in the column Featured Set the full record of required parameter: Analog Public, but not the part of it (no results will be shown if we set this parameter like: Analog)

5.6. Get familiar with the content of the tables of the CMG application more detailed.

6. The content of the protocol

6.1. The answers to the key questions 3.1-3.4.

6.2. The description of the appearance of MN applications.

6.3. The differences in possibilities of administration for different modes of access to the nodes.

6.4. The possibilities of the basic administration commands.

6.5. The content of the tables of CMG application.

Laboratory work №3

Description of switching and access nodes

MCA, MLC of DSS SI2000

1. The purpose of the work

Acquaintance with architecture of switching and access nodes. To learn principles of designation of parameters of nodes. To consider the rules of labeling of removable blocks of modules MLC, MCA.

2. Key positions

2.1 Architecture of nodes. The switching node MCA consists of the central and peripheral parts.

The central part has backup and it contains such cards:

• CCA – control device of the central node;

• IVA – hard drive adapter;

• CVC – central processor;

• IHA –extended interface of a high speed serial trunk;

• DVA – battery static memory device (SRAM).

The peripheral part:

• TPC – primary access interface;

• CDA – communication controller;

• RPA – the card for primary access protection;

• RPC – the card for primary access measurements.

The access node MLC consists of the central and peripheral parts as well.

The central part:

• CLC – control device of digital access node;

• CDG – communication controller and processor;

• QMB – flash drive or IDE hard drive;

• TPE – interface for E1 trunks, 4*2 Mbps;

• DDD – DSP processor;

• PLC - power supply and generator of ringing current;

• KLB – testing block of subscriber lines.

The peripheral part:

• SAC – the card supporting 32 analog subscriber lines with interface Z;

• SBx – the card supporting 16 digital subscriber lines with interface S or U;

• TAx – the card supporting physical subscriber lines along the direction of analog exchanges of the network.

2.2 The description of nodes, labelling of cards. During the work with MN nodes will be described with using of the special format (Example is shown in the table 3.1

Table 3.1 – The labelling of switching and access nodes in MN

Name of the product	Release
	MN Release	Node Release	DB Release	Data Release
MCA (SN) CS5083AU 380	PANM0A20	MVVG0A24	PBFB0A10	PBFA0A17
MLC (SAN) LS5083 AU140	PAGY0A22	MVVC0A41	PBHB0A10	PHNA0A17
MLC (ANC)LA5053AX100	PHPC0A09	MVYM0A20	PJMB0A07	MVYN0A12

Where:

MCA (SN) CS5083AU380 – the general node designation;

SN (switching node) – the designation of belonging of the node to the type “Switching Node” (such variants are also possible: SAN (switch and access node) used as RSwM and AN (access node) used as local or remote SM);

CS (central switch) – the designation of the node location in the network, the central node (such variants are also possible: LS (Line switch) and LA (line access);

5 – Hardware version. Almost all Iskratel equipment with channel switching has the version 5. The nodes with the packet switching have the version 6.

83 – Software version. On the same hardware different software version can be installed;

AU – the index, meaning that the node has specification for operation in Ukrainian networks;

380 – the number of the packet of software.

The designation of cards in modules has the following view:

UTA XXXX YY XXX – the removable block;

ETN XXXX YY XXX – additional card

The first 3 letters are the code of the card;

XXXX – the variant of the card;

YY – production condition (state).

Here is the example:

UTA 5008 BD 011 CCA

The codes of all cards of nodes MLC, MCA are shown in the table 3.2.
