To configure SDH sub-channels

Purpose

SDH sub-channels are available on deep channelized OC12 and OC3 ports. SDH AU4 channels support the following payload types:

  • TU3

  • TU11

  • TU12

SDH AU3 channels support the following payload types:

  • DS3

  • E3

  • TU11

  • TU12

Perform this procedure to configure SDH sub-channels on ports that provide channelized services. You must first configure port framing to SDH since default framing on SONET/SDH ports is SONET.

Steps
 
1 

Choose Equipment from the navigation tree view selector.

2 

Right-click on the device on which you want to configure SDH sub-channels and select Properties. The Network Element (Edit) form opens.

3 

On the Network Element (Edit) form navigation tree, expand the Shelf icon.

  1. SONET Sts1 channelization and SDH Au3 channelization are equivalent. Go to Step 6 of To configure SONET sub-channels .

  2. If you choose SONET Sts3 (Sdh Stm1), the Sts3 SONET Channel (Create) form opens. Go to Step 9 .

    The Payload Type parameter for SDH STM1 (AU4) is set to TUG3. There is no SONET framing equivalent. Go to Step 9 .

    If you are configuring a 4 x Channelized OC3/OC12 ASAP SFP adapter card on a 7705 SAR, Release 7.0 R5 or later, when the MDA Mode is OC12 with SDH framing, you can create an Sts1 and Sts3 channel type with a DS1 or an E1 channel.

9 

Configure the required parameters.

10 

Click on the States tab and configure the Administrative State.

11 

Click OK. The STM1 (AU4) channel appears in the navigation tree under the port of the daughter card. It contains three TUG3 groups.

12 

Right-click on a TUG3 group and choose Properties. The Sdh Tug3 (Edit) form opens.

13 

Choose one of the following options to configure the Payload Type parameter:

  1. PDH Tu3. Click Cancel and go to Step 14 to create a TU3 channel.

  2. SONET VT15 (SDH Tu11). Click Apply and go to To create VT15 (TU11) or VT2 (TU12) sub-channels .

  3. SONET VT2 (SDH Tu12). Click Apply and go to To create VT15 (TU11) or VT2 (TU12) sub-channels .

14 

To create a TU channel, right-click on the TUG3 group and choose Create Channel. The TU3 Channel (Create) form opens.

15 

Configure the required parameters.

16 

Click on the States tab and configure the Administrative State.

17 

Click OK. A TU3 channel is created under the TUG3 group in the navigation tree.

18 

Right-click on the Tu3 and choose Create Channel. The DS3/E3 Channel (Create) form opens.

The E3 is the only payload type available.

19 

Configure the required parameters.

20 

Click on the States tab and configure the Administrative State.

21 

Click OK. An E3 clear channel is created under the AU4/TUG3 in the navigation tree.
