Configuring CESoPSN on Channelized OC3/STM1 (Multi-Rate) Circuit Emulation MIC with SFP

 

To configure CESoPSN options on a Channelized OC3/STM1 (Multi-Rate) Circuit Emulation MIC with SFP, you must configure the speed and framing mode at MIC level and configure the encapsulation as CESoPSN on DS interfaces.

Configuring SONET/SDH Rate-Selectability

You can configure rate-selectability on the Channelized OC3/STM1 (Multi-Rate) MICs with SFP(MIC-3D-4COC3-1COC12-CE) by specifying the port speed. The Channelized OC3/STM1 (Multi-Rate) Circuit Emulation MIC with SFP is rate-selectable and its port speed can be specified as COC3-CSTM1 or COC12-CSTM4.

To configure port speed to select a speed option of coc3-cstm1 or coc12-cstm4:

  1. In configuration mode, go to the [edit chassis fpc slot pic slot port slot] hierarchy level.

    For example:

  2. Set the speed as coc3-cstm1 or coc12-cstm4.

    For example:

    Note

    When the speed is set as coc12-cstm4, instead of configuring COC3 ports down to T1 channels and CSTM1 ports down to E1 channels, you must configure COC12 ports down to T1 channels and CSTM4 channels down to E1 channels.

Configuring SONET/SDH Framing Mode at the MIC Level

To set the framing mode at the MIC (MIC-3D-4COC3-1COC12-CE) level, for all four ports on the MIC, include the framing statement at the [edit chassis fpc slot pic slot] hierarchy level.

After a MIC is brought online, interfaces are created for the MIC’s available ports on the basis of the MIC type and the framing option used.

  • If you include the framing sonet statement, four COC3 interfaces are created when the speed is configured as coc3-cstm1.

  • If you include the framing sdh statement, four CSTM1 interfaces are created when the speed is configured as coc3-cstm1.

  • If you include the framing sonet statement, one COC12 interface is created when the speed is configured as coc12-cstm4.

  • If you include the framing sdh statement, one CSTM4 interface is created when the speed is configured as coc12-cstm4.

  • If you do not specify framing at the MIC level, then the default framing is SONET for all the ports.

Note

If you set the framing option incorrectly for the MIC type, the commit operation fails.

Bit error rate test (BERT) patterns with all binary 1s (ones) received by CT1/CE1 interfaces on Circuit Emulation MICs configured for CESoPSN do not result in an alarm indication signal (AIS) defect. As a result, the CT1/CE1 interfaces remain up.

Configuring CESoPSN Encapsulation on DS Interfaces on CT1 Channels

This topic includes the following tasks:

  1. Configuring COC3 Ports Down to CT1 Channels

  2. Configuring CT1 Channels Down to DS Interfaces

  3. Configuring CESoPSN on DS Interfaces

Configuring COC3 Ports Down to CT1 Channels

When configuring COC3 ports down to CT1 channels, on any MIC configured for SONET framing (numbered 0 through 3), you can configure three COC1 channels (numbered 1 through 3). On each COC1 channel, you can configure a maximum of 28 CT1 channels and a minimum of 1 CT1 channel based on the time slots.

When configuring COC12 ports down to CT1 channels on a MIC configured for SONET framing, you can configure 12 COC1 channels (numbered 1 through 12). On each COC1 channel, you can configure 24 CT1 channels (numbered 1 through 28).

To configure COC3 channelization down to COC1 and then down to CT1 channels, include the partition statement at the [edit interfaces (coc1 | coc3)-mpc-slot/mic-slot/port-number] hierarchy level:

Note

To configure COC12 ports down to CT1 channels, replace coc3 with coc12 in the following procedure.

  1. In configuration mode, go to the [edit interfaces coc3-mpc-slot/mic-slot/port-number] hierarchy level.

    For example:

  2. Configure the sublevel interface partition index and the range of SONET/SDH slices, and set the sublevel interface type as coc1.

    For example:

  3. Enter the up command to go to the [edit interfaces] hierarchy level.

    For example:

  4. Configure the channelized OC1 interface and the sublevel interface partition index, and set the interface type as ct1.

    For example:

To verify the configuration, use the show command at the [edit interfaces] hierarchy level.

Configuring CT1 Channels Down to DS Interfaces

To configure CT1 channels down to a DS interface, include the partition statement at the [edit interfaces ct1-mpc-slot/mic-slot/port-number:channel:channel] hierarchy level:

  1. In configuration mode, go to the [edit interfaces ct1-mpc-slot/mic-slot/port-number:channel:channel] hierarchy level.

    For example:

  2. Configure the partition, the time slots, and the interface type.

    For example:

    Note

    You can assign multiple time slots on a CT1 interface. In the set command, separate the time slots by commas and do not include spaces between them. For example:

To verify this configuration, use the show command at the [edit interfaces ct1-1/0/0:1:1] hierarchy level.

An NxDS0 interface can be configured from channelized T1 interface (ct1). Here N represents the time slots on the CT1 interface.

The value of N is 1 through 24 when a DS0 interface is configured from a CT1 interface.

After you partition the DS interface, configure the CESoPSN options on it. See Setting the CESoPSN Options.

Configuring CESoPSN on DS Interfaces

To configure CESoPSN encapsulation on a DS interface, include the encapsulation statement at the [edit interfaces ds-mpc-slot/mic-slot/port-number:channel:channel:channel] hierarchy level.

  1. In configuration mode, go to the [edit interfaces ds-mpc-slot/mic-slot/port-number:channel:channel:channel] hierarchy level.

    For example:

  2. Configure CESoPSN as the encapsulation type and the logical interface for the DS interface.

    For example:

To verify this configuration, use the show command at the [edit interfaces ds-1/0/0:1:1:1] hierarchy level.

Configuring CESoPSN Encapsulation on DS Interfaces on CE1 Channels

This topic includes the following tasks:

Configuring CSTM1 Ports Down to CE1 Channels

On any port configured for SDH framing (numbered 0 through 3), you can configure one CAU4 channel. On each CAU4 channel, you can configure 31 CE1 channels (numbered 1 through 31).

To configure CSTM1 channelization down to CAU4 and then down to CE1 channels, include the partition statement at the [edit interfaces (cau4 | cstm1)-mpc-slot/mic-slot/port-number] hierarchy level, as shown in the following example:

  1. In configuration mode, go to the [edit interfaces cstm1-mpc-slot/mic-slot/port-number] hierarchy level.

    For example:

  2. On the CSTM1 interface, set the no-partition option, and then set the interface type as cau4.

    For example:

  3. Enter the up command to go to the [edit interfaces] hierarchy level.

    For example:

  4. Configure the MPC slot, the MIC slot, and the port for the CAU4 interface. Set the sublevel interface partition index and set the interface type as ce1.

    For example:

To verify this configuration, use the show command at the [edit interfaces] hierarchy level.

Configuring CSTM4 Ports Down to CE1 Channels

Note

When the port speed is configured as coc12-cstm4 at the [edit chassis fpc slot pic slot port slot] hierarchy level, you must configure CSTM4 ports down to CE1 channels.

On a port configured for SDH framing, you can configure one CAU4 channel. On the CAU4 channel, you can configure 31 CE1 channels (numbered 1 through 31).

To configure CSTM4 channelization down to CAU4 and then down to CE1 channels, include the partition statement at the [edit interfaces (cau4|cstm4)-mpc-slot/mic-slot/port-number] hierarchy level.

  1. In configuration mode, go to the [edit interfaces cstm4-mpc-slot/mic-slot/port-number] hierarchy level.

    For example:

  2. Configure the sublevel interface partition index and the range of SONET/SDH slices, and set the sublevel interface type as cau4.

    For oc-slice, select from the following ranges: 1–3, 4–6, 7–9, and 10–12.

    For partition, select a value from 1 through 4.

    For example:

  3. Enter the up command to go to the [edit interfaces] hierarchy level.

    For example:

  4. Configure the MPC slot, the MIC slot, and the port for the CAU4 interface. Set the sublevel interface partition index and set the interface type as ce1.

    For example:

To verify this configuration, use the show command at the [edit interfaces] hierarchy level.

Configuring CE1 Channels Down to DS Interfaces

To configure CE1 channels down to a DS interface, include the partition statement at the [edit interfaces ce1-mpc-slot/mic-slot/port:channel] hierarchy level.

  1. In configuration mode, go to the [edit interfaces ce1-mpc-slot/mic-slot/port:channel] hierarchy level.
  2. Configure the partition and the time slots, and set the interface type as ds.

    For example:

    Note

    You can assign multiple time slots on a CE1 interface. In the set command, separate the time slots by commas and do not include spaces between them. For example:

To verify this configuration, use the show command at the [edit interfaces ce1-1/0/0:1:1 hierarchy level.

An NxDS0 interface can be configured from a channelized E1 interface (CE1). Here N represents the number of time slots on the CE1 interface.

The value of N is 1 through 31 when a DS0 interface is configured from a CE1 interface.

After you partition the DS interface, configure the CESoPSN options.

Configuring CESoPSN on DS Interfaces

To configure CESoPSN encapsulation on a DS interface, include the encapsulation statement at the [edit interfaces ds-mpc-slot/mic-slot/port-number:channel:channel:channel] hierarchy level.
