To create TDM DS1 or E1 channels

Purpose

Perform this procedure to create DS1/E1 channels and child objects on a channelized DS1/E1 port.

Note: If you are using the XML API to create a DS1 or E1 channel, the create request creates a channel with a G704 CRC framing type for E1 channels and ESF for DS1 channels. To modify the channel framing type requires a second request.

Steps
 
1 

On the equipment tree, right-click on the device where you want to configure TDM DS1 or E1 channels and select Properties. The Network Element (Edit) form opens.

2 

On the Network Element navigation tree, expand to the port level.

3 

Click on a port. The Port form opens.

4 

Configure the required general parameters.

5 

Click on the DS1/E1 tab and configure the required parameters.

6 

Click OK.

7 

Right-click on the port and choose Create Channel. The DS1/E1 Channel (Create) form opens. If there are no channels available on that port, the Create Channel menu option is dimmed.

8 

Click OK.

To create DS0 channel groups:

  1. On the navigation tree, right-click on a DS1 or E1 channel under the required port and choose Create Channel. The DS0 Channel Group (Create) form opens.

  2. Configure the required parameters.

    For the Local Channel ID parameter, for a DS0 group from a DS1 channel, choose from 1 to 24. For a DS0 group from an E1 channel, choose from 2 to 32.

    Note:

    All channel groups on a 7705 SAR ASAP port must have the same mode configured. When the first channel group is configured, all other channel groups on the port must be set to the same mode.

    The default encapsulation type for the 7705 SAR is N/A. The encapsulation type must be changed from N/A to a valid type. For instance, to support CAS signaling, the encapsulation type must be set to CEM. After a valid encapsulation type is configured for a channel group, the encapsulation type cannot be changed for that channel group. To change the encapsulation type, the channel group must be deleted and recreated.

    On a 16/32x Channelized ASAP, you must configure the MDA mode in order to use certain encapsulation types. See To configure an MDA for more information on configuring the MDA mode.

  3. Click on the Channel Group tab and configure the required parameters.
