Chapter 1 System Introduction

1.1 System Overview

The IDM system adopts NetGuard as its network management platform, enabling unified network management through the control panel. The network management system can manage the following items:

a. Query and set network host status, network topology, working conditions, and overall alarm status

b. Query the type, working conditions, and overall alarm status of each card

c. Set and query E1 alarm masking for each tributary

d. Set the automatic query function

e. Set and query DXC connection assignment for 4 E1 timeslots

f. Set and query 30-channel plug-in card services and N*64K services

The overall block diagram of the network management system is as follows:

4.2.1 Setting Up the Network

After successful login, enter the main management window and select "File 1" in the "Tree Form" dialog box. In the right-click menu, there is "Add Network" where you can add your own network (by default, the network "NET00-0" has already been created for you). Select "NET00-0", right-click, and click "Object Properties" in the pop-up menu. In the network object properties: select "SNMP Express" as the network type; select the COM port currently used by the PC for the communication port (e.g., COM1); the "Source Address" refers to the ADM120 host address connected to the PC, which can range from 0 to 32 (e.g., Station 1 connected to the PC). After configuration, click "OK".

4.3.1 Host Device Status Query and Setting Function

Directly select the host to be queried in the tree directory, as shown in Figure 14:

@@IMG13@@

Figure 14

Setting Introduction:

There are four clock modes: Master Clock, External Clock, E1 Port Extracted Clock, and Synchronous User Port Extracted Clock. For the ADM120, a high-precision clock source is already built into the unit, so the network element that the user wants to set as the master clock should be set to "External Clock", and there can only be one master clock in the entire network. Other network elements can only be set to E1 Port Extracted Clock or Synchronous User Port Extracted Clock. The synchronous user ports include V.35, V.24, and other data channels.

4.3.1.1 Network Management Channel Selection: You can select Timeslot 0 or Timeslot 1 of the E1 channel.

4.3.1.2 Network Management Topology Parameters have four options:

1. Single Direction: uses only the first E1 channel for network management transmission;
2. Dual Direction: uses the first and second E1 channels for network management transmission;
3. Triple Direction: uses the first, second, and third E1 channels for network management transmission;
4. Quad Direction: uses the first, second, third, and fourth E1 channels for network management transmission;

4.3.1.3 CRC Enable: CRC can be disabled or enabled via the network management system.

Important Notes:

The above settings do not apply to the "Economy Model IDM-120P".

The network topology parameters must match the actual number of E1 tributaries in use.

When the host is a slave station, it must be set from which E1 tributary the clock is extracted.

When the returned information matches the setting information, the settings have taken effect.

4.3.2 Four E1 Tributary Status Query and Setting Function

In the "TreeForm", select "E1 Channel" and the view window will display as shown in Figure 15.

@@IMG14@@

Figure 15

Configuration Introduction:

Configure the E1 mode by selecting any of channels A, B, C, or D (check the boxes), then click "Configure E1 Mode" to complete the configuration. The selected E1 channels use PCM31 mode, which does not transmit signaling (Timeslot 16); otherwise, signaling is transmitted in Timeslot 16.

The alarms of the four output E1 channels can be masked (by selecting and configuring).

Querying the E1 mode allows you to verify whether the above settings were successful. Once the returned information matches the configuration information, the configuration has taken effect.

The returned status information shows the alarm status of the E1 channels. A lit indicator indicates an alarm. The meanings of each alarm are as follows:

LOS: Indicates Loss of Signal alarm, '1' indicates an alarm.

AIS: Indicates Remote Alarm (i.e., all-ones alarm received on the line);

LOF: Indicates Loss of Frame;

RAL: Indicates Remote Alarm Indication A1;

LOSMF: Indicates Signaling Multiframe Loss alarm;

CRCI: Indicates CRC-4 Check Error alarm;

LOCMF: Indicates Multiframe Loss alarm;

Chapter 5 Typical Configuration Examples

5.1 Four Voice Channels and One Network Channel Point-to-Point Interconnection

5.1.1 Let us examine an example of two economy-type devices interconnected, as shown in the connection diagram below:

Figure 19

5.1.2 Now we set Device 1 as the master station (Station 1) and Device 2 as the slave station (Station 2), using Serial Port 1, with the network management cable connected to Station 1. The configuration is as follows, and the network management object properties are shown in Figure 20.

Figure 20

5.1.3 The network element object properties of the first network element (Device 1) are shown in Figure 21, and those of the second network element (Device 2) are shown in Figure 22.

Figure 21

Figure 22

5.1.4

The view window settings of the first network element (Device 1) are shown in Figure 23, and the view window settings of the second network element (Device 2) are shown in Figure 24. However, since the second network element is an economy-type IDM, the settings of the second network element do not take effect; they are provided here for reference only in other scenarios.

Figure 23

Figure 24

5.1.5

The E1 channel settings are shown in Figure 25. When transmitting signals with signaling such as voice, PCM30 mode should always be used. Unless under special circumstances, the output is generally not masked.

Figure 25

5.1.6 The downstream bus configuration is shown in Figure 26. The signal is input from the first channel of the coaxial cable, then split into one signaling signal (timeslot 16), one network management signal (timeslot 0), and 30 service signals. The 30 service signals are divided into four groups and sent to the four buses on the backplane, then to each card. The upstream bus is the reverse of this process, as shown in Figure 27.

Figure 26

Figure 27

5.1.7 The user interface configuration is shown in Figure 28 below. The figure shows one Ethernet card and two telephone cards configured.

Figure 28

Note:

The telephone cards occupy the first four timeslots; the 26 timeslots after timeslot 5 are all used by Ethernet.

When the user interface configuration conflicts with the installed cards, a priority order applies: V24 > N*64K > card;

The timeslots allocated to N*64K must be consecutive timeslots;

User interface configuration must be performed on the basis of the upstream/downstream configuration.

The E1 channel, upstream DXC, downstream DXC, and user interface configurations of the two IDM devices are similar. As long as the cards correspond to each other, the configurations can be identical (not repeated here).

5.2 Four Voice Channels and One Network Channel: One Master Station with Four Slave Stations

Let us examine the example of four voice channels and one network channel with one master station and four slave stations. The connection (telephones for Devices 3-5 are not shown) is as follows. It is worth noting that all four slave stations should use the first 2M to extract the clock.

Now we set Device 1 as the master station (Station 1) and the other devices as slave stations, using Serial Port 1, with the network management cable connected to Station 1. The configuration is as follows, and the network management object properties are shown in Figure 21. Now, on the default basis (four network elements), add one more network element, as shown in Figure 30.

Figure 30

The network element object properties of the first network element (Device 1) are shown in Figure 21, those of the second network element (Device 2) are shown in Figure 22, and the third through fifth network elements are similar to the second.

The settings in the view window of the first network element (Device 1) are shown in Figure 31 (if it is not an economy-type product), and the view window settings of the second network element (Device 2) are shown in Figure 24. The third through fifth network elements are similar to the second. Note that for the economy-type PCM120, all settings here are invalid.

Figure 31

The E1 channel settings for each network element are shown in Figure 25. When transmitting signals with signaling such as voice, PCM30 mode should always be used, and the output is generally not masked unless under special circumstances.

The downstream bus configuration for each network element is shown in Figure 26. The signals are input from the four coaxial cables respectively, sent to the four buses on the backplane, and then to each card. The upstream bus is the reverse of this process, as shown in Figure 27.

The user interface configuration of Device 1 is shown in Figure 32 below. The figure shows four Ethernet cards and eight telephone cards configured.

Figure 32

The user interface configuration of Devices 2 through 5 is shown in Figure 28. Refer to the relevant settings in the four-voice-one-network point-to-point interconnection example. The figure shows one Ethernet channel and two telephone channels configured. At this point, the configuration of four voice channels and one network channel with one master station and four slave stations is complete.
