To configure TDM DS1 or E1 channels

Purpose

Perform this procedure to configure DS1/E1 channel parameters and child objects on a channelized DS1/E1 port, add a DS0 channel group, collect and view performance statistics, or view alarm information.

Steps
 
1 

In the navigation tree equipment view, right-click on the device you need to configure TDM DS1 or E1 channels and choose Properties. The Network Element (Edit) form opens.

2 

Expand the Shelf icon to the channel level and choose a DS1 or E1 channel. The DS1/E1 Channel (Edit) form opens.

3 

Click on the States tab and configure the Administrative State parameter.

4 

Click on the Channel tab. The DS1/E1 Channel (Edit) form opens.

5 

Configure the required parameters.

The Synchronous Status Messages, E1 Tx DUS/DNU, and E1 SSM-Bit parameters are configurable only on E1 channels on a 7705 SAR.

The Channel Framing parameter must be set to E1-unframed to create a DS0 channel under the E1 channel.

The Clock Source parameter value Differential is only supported on the following 7705 SAR cards:

  • 16/32 × Channelized DS1/E1 ASAP v2 on a 7705 SAR-8, 7705 SAR-8 v2, or 7705 SAR-18

  • 4 × Channelized DS3/E3 ASAP on a 7705 SAR-8, 7705 SAR-8 v2, or 7705 SAR-18, Release 6.1 R3 or later

  • 4 × Channelized OC3/OC12 ASAP SFP on a DS1/E1 channel, on a 7705 SAR-8, 7705 SAR-8 v2, or 7705 SAR-18, Release 6.2 R1 or later

  • ASAP channelized card on a 7705 SAR-A

Note: If you create an MLPPP bundle and the DS1 BER exceeds a threshold, the PPP link is automatically removed from the MLPPP bundle.

6 

Add a DS0 channel group, if required.

Note: For the 7250 IXR-R6, you can only create a DS0 channel under the E1 channel (not the DS1 channel) of a 32-port Any Service Channelized DS1/E1 Multi-Sync MDA.

  1. Click on the SubChannels tab.

  2. Click on the Create Cha... tab. The DS0 Channel Group (Create) form opens.

  3. Configure the required parameters.

    Note:

    On a 16/32x Channelized ASAP, you must configure the MDA mode in order to specify the encapsulation type. See To configure an MDA for more information about configuring the MDA mode.

    You must set the value of the Encapsulation Type parameter to CEM if you are configuring an MDA card of type 16 × Channelized DS1/E1 ASAP v2 or 32 × Channelized DS1/E1 ASAP v2 on a 7705 SAR-8 or 7705 SAR-18.

  4. Click OK.

  5. Click OK.

7 

Perform one of the following:

  1. Click Collect to collect performance statistics data on demand. The collected statistics are listed on the form.

  2. Click Collect All to collect one on-demand statistics record for each statistic type that the object supports. The collected statistics are listed on the form.

8 

Click on the Faults tab to view alarm information, if required.

Note: If are configuring a 7705 SAR and selected a clock source of adaptive, you can click on the Adaptive Clock History tab to view channel adaptive clock performance data for the preceding 15 min.

9 

Save your changes and close the forms.
