How to properly configure the Orderwire on OSN Equipment-part1

Configuring Orderwire

To provide the maintenance personnel with a dedicated express orderwire channel, you can configure orderwire for NEs.

Prerequisites

You must be an NM user with NE operator authority or higher.

Procedure

1.     In the NE Explorer, select an NE and choose Configuration > Orderwire from the Function Tree. Click the General tab.

2.     Click Query to query information from the NE.

3.     Set Call Waiting Time(s)Telephone No. and orderwire ports.

NOTE:

Call Waiting Time should be set to the same value for all NEs with orderwire communication. When the number of NEs is smaller than 30, set the value to 5 seconds. Otherwise, set it to 9 seconds.

The telephone number cannot repeat in the same orderwire subnet.

Set the length of the telephone number according to the actual requirements. The maximum length is eight digits and the minimum length is three digits. In the same orderwire subnet, the number length must be the same. For the settings of the orderwire subnet, refer to Dividing Orderwire Subnets.

The length of the telephone number must be the same as that of the conference call number.

If the length of the subnet number is 1, the first digit of the two orderwire numbers must be the same. If the length of the subnet number is 2, the first two digits of the two orderwire numbers must be the same.

4.     Click Apply. A prompt appears telling you that the operation was successful.

5.     Click Close.

 

 

Configuring Conference Calls

To provide the maintenance personnel with a dedicated express channel that allows concurrent voice communication among multiple NEs, you can configure the conference calls for NEs.

Prerequisites

You must be an NM user with NE operator authority or higher.

Procedure

1.     In the NE Explorer, click the NE and choose Configuration > Orderwire from the Function Tree. Click the Conference Call tab.

 

2.     Click Query to query the conference call configuration of the NE.

3.     In the Available Conference Call Port pane, select the port where you want to configure a conference call, and click Configuring Conference Calls_2.

NOTE:

If a network consists of OptiX OSN 1500/2500/2500 REG/3500/3500 II/7500 NEs, the conference call ports are automatically enabled without the need of manual enabling. If a network consists of OptiX OSN 1500/2500/2500 REG/3500/3500 II/7500 NEs and other OptiX OSN NEs, manually enable the conference call ports as front.

4.     Click Apply.

A prompt appears telling you that the operation was successful.

5.     Click Close.

6.     Click the General tab, and set Conference Call number.

NOTE:

The conference call number for all NEs must be the same, and must have the same length as the orderwire phone number. If the orderwire phone number has four digits, the conference call number is recommended to be 9999.

7.     Click Apply.

Example

You can follow the sample configuration to avoid a conference call loop.

As shown in the figure, if conference calls are configured for all optical ports, howls are caused. Configure a conference call for NE3-7-SL16-1 only, rather than NE3-12-SL16-1.
