SI22565A - Device and procedure for the control of telecommunication devices viaa data network - Google Patents

Abstract

The device and procedure for the control of telecommunication devices via a data network which enable the use of the so-called "INBAND" control option and managing of communication devices with the help of DLAMs well understood that this includes adhering to the TCP/IP standards of the protocol stack. Via ipDSLAMs with ADSL 2+ modem or without it as well as the application of a switch (which is enabled by several terminal points for end-user devices) it is possible to establish the required communication for the control and management of end-user devices to the needs of TS. There are two operating variations of the solution, which are: a) the end-user device connected directly to the Ethernet port of the ipDSLAM, b) end-user device connected by using the ADSL 2+ modem. In most cases the solution is applied, only when the distance of the terminal facility for the control and management is more than 90 meters, then solution 2 is used.

A technical problem

Due to the renewal of the product range of equipment manufacturers - ISDN products, which will result in the abandonment of their production, it is necessary to find a new solution for remote control and management.

The control and management of end devices must be carried out in such a way as to ensure smooth operation and maximum security against intrusion into the system of control and management of the fixed line operator.

The state of the art

In order to understand the prior art, it is first necessary to describe the physical environment in which the invention operates. For technical connection purposes, the landline operator uses a technical network - for the purposes of this application, called DCN TS or short DCN.

Since the DCN network is basically an IP network and is branched out by most physical TS locations, it is often used for other purposes outside the telecommunications field - e.g. entry control into TS facilities, climate control and management ...

This network is also connected to the IP / MPLS network of the landline operator, which is intended for Internet service users.

VLAN tagging between IP / MPLS network is used for communication of end devices in IP / MPLS network and traffic is not tagged within DCN network. This mode is already used in the prior art to control ipDSLAMs.

Devices within the DCN network and end devices use a private IP address space.

In the prior art, ISDN products are used to control devices using communication over ISDN tel. central. These devices come with custom software.

Description of the new solution

The device and procedure for monitoring telecommunication devices over the data network solves the technical problem described above, since the mass installation of broadband devices (DSLAMs) in the landline operator (hereinafter referred to as TS) is intended to support end-user services , which enable mass use of applications - the basis is broadband Internet, showed the possibility of so-called INBAND control and management of communication devices using DSLAMs, of course, in accordance with the standards of the TCP / IP protocol stack.

Via ipDSLAM, with or without ADSL 2+ modem, and using a switch (allowing multiple terminals for end devices), the necessary communication can be established to control and manage the end devices for TS purposes.

There are two working versions of the solution, namely:

a) terminal device connected directly to the ethemet port of ipDSLAM (Figure 2),

b) terminal device connected using an ADSL2 + modem (Figure 3).

In most cases, solution a is used, but when the distance of the final control and management facility is more than 90 meters, solution b is used.

The following advantages and surprising technical advantages will be achieved in the way described:

• Communication quality is undoubtedly safer and higher quality • Significantly greater bandwidth compared to ISDN • Relatively short time required to build a new connection needs, • the solution works in an already established TS environment, but can be used in other environments.

The essence of the proposed patent is not only the device or part of it, but also the set of procedures required to connect the end devices (12) to the TS control systems in a way that provides a sufficiently high level of security and the required functionality.

Depending on the required functionality of the final devices (12), the following changes were necessary:

• Firewall (5) - Depending on the type of terminal device, it is allowed the type of traffic required for its control and management. The control system can be located on the DCN TS (1) or the TS (3) business network. If the control system is located on the TS (3) business network, changes must be made to the firewall on the connection between the TS (3) business network and the TSN (1) DCN.

• IP / MPLS network (2) - the existing IP / DSLAM control and management link (4) needs to be routed to the needs of the end devices (12).

• ipDSLAM (3)

a) terminal device (12) connected directly to the ethemet port of ipDSLAM (Figure 2) - on the ipDSLAM (4) used in our case we used the free ethemet port, which had to be administered in such a way; that the sessions removed the tagging from the VLAN for control and management.

b) terminal device connected using ADSL2 + modem (Figure 3) - in this example, it is necessary to administer the ADSL2 + port of ipDSLAM (4). This port had to remove pre-configured settings for TS end users, and reconfigured the port with new settings, the most important change being the ATM parameters of VPI and VCI. It is also necessary to remove tagging from the VLANs for monitoring and managed on this port. In this variant, the settings on the ADSL2 + modem (10) must also be changed in accordance with the changes under this point.

• ADSL2 + modem (10) - It is essential for the settings of this device to be different from the settings of similar devices for TS end users. The likelihood of an intrusion into the system is therefore minimized.

In the following, the essence of the invention is described in the drawings, with the drawings forming an integral part of the application. The sketches show the following elements

Control and Management Network (DCN) (1); IP / MPLS network (2); TS Business Network (3); ipDSLAM (4); Fire barrier (5); IP / MPLS and ipDSLAM connection (6); DCN and IP / MPLS network invocation (7); Semi-permanent ISDN connection (8); Ethernet switch (9); ADSL2 + modem (10); ISDN router (11); End devices (12); IpDSLAM physical location (13); Physical location of remote end devices (14).

Figure 1 shows the current state of control and management of devices using semi-permanent ISDN links and an ISDN router. Communication between the control systems in the control and management network - hereinafter referred to as DCN (1) and the terminal devices (12) is via semi-permanent ISDN connections (8), which provides satisfactory security against intrusion into TS networks.

Figure 2 shows a new technical solution - control and management of end devices (12) over IP / MPLS network (2) by connecting directly to ipDSLAM (4).

Most of the control systems are located on the DCN network (1), and a smaller part also in the TS business network (3). Networks (1, 2, 3) are interconnected via firewalls (5).

DCN and IP / MPLS broadband (7) (this link is still in the ATM layer in one part). VLAN tagging is not used on this link.

However, broadband IP / MPLS and ipDSLAM (6) use VLAN tagging. The same physical path also provides services to the end user. To control and manage the end devices (12), we used an existing VLAN to manage ipDSLAM (4) in our solution.

An Ethernet switch (9) allows connection of multiple terminals. VLAN tagging is not used in the segment between ipDSLAM (4) and end devices (12).

Figure 3 shows a new technical solution - control and management of devices for longer distances of end devices (12) using ADSL2 + modem (10).

The connection between the control systems in the DCN network (1) and the ipDSLAM (4) proceeds in the same way as shown in Figure 2. The end devices (12) can be connected to the ipDSLAM (4) at a distance enabled by ADSL2 + technology. The physical location of ipDSLAM (13) can also be several kilometers away from the physical location of the end devices (14).

This technical solution uses the same ADSL2 + modem (10) as for TS service users.

The present invention is both a process as described and a device that performs such a process according to the invention.

It is quite clear that a different embodiment of the present invention may also be carried out, which does not, however, change substantially.
