1 Overview

1.1 Presentation

Use this scenario to change the extraction point from the A interface (MSC) tothe PSDN (BSC). This change includes all BSCs from one 9153 OMC-R.

The Alcatel-Lucent solution is based on CISCO routers, which decreases the

cost of the 9153 OMC-R / BSC connection, and is also useful, given thatmore and more GSM networks are being installed in countries without anX.25 infrastructure. (They are not able to rely on public X.25 networks for theconnection between the 9153 OMC-R and the remote BSC).

In the initial state, each BSC communicates with an 9153 OMC-R via one CPRxboard (central processor) at a time. The second board is used only if the link tothe first one is out of order, when redundancy is set at the BSC site.

In the initial state, the 9153 OMC-R is connected to the A Interface via the HSIboard, using CISCO routers. The HSI board has four RS-449 ports. The twofirst connectors (0 and 1) are only dedicated to BSC connection and aremandatory for redundancy. The two other connectors (2 and 3) are not used.

The following figures illustrate the main phases for going from an X.25 via Aterconfiguration to an X.25 via PSDN.

2.3.1.2 Check X.25 Link Status


- Check X.25 Link Status. 9153 OMC-R 2 min./ BSC

None.

To check X.25 link status:

1. Perform a PAD connection from an 9153 OMC-R to its BSCs to test thenormal and redundant links of all BSCs. The result must be ’Connected’even if there is no further reaction.

pad 0.<X.25 BSC first address>

pad 0.<X.25 BSC second address>pad 1.<X.25 BSC first address>

pad 1.<X.25 BSC second address>

2. To exit this command, type (one after the other), [ CTRL p ], [ a ], [ q ].

Enter the X.25 BSC address without the prefix. For example, for a BSC with thefirst address 368215 and the second address 368245, type:

pad 0.8215

pad 0.8245

pad 1.8215

pad 1.8245

If error 00f0 appears, the X.25 BSC address value is incorrect.

If there is no redundancy, consult the client representative or contactAlcatel-Lucent Support.
