Parameter Description: CES Port (OptiX OSN 500/550)

Parameter Description: CES Port (OptiX OSN 500/550)

Before configuring a CES service, you must configure the CES port.

Channelized STM-1 Port

Configuring a channelized STM-1 port includes setting of the parameters such as the encapsulation type of the port, the maximum data packet size, and the enabling status of the laser.

Table 3-324  Parameters for the attributes of an SDH port
Field Value Range Description
Port For example, 21-CQ1-1(PORT-1)

Displays the port name.

Name For example, port1

Specifies the name of the port specified by the user.

Port Mode Layer 1

Displays the working mode of the CES port Layer 1 indicates the channelized STM port is currently available.

The OptiX OSN equipment currently supports only Layer 1 in Port Mode. In this case, the OptiX OSN equipment can transmit channelized STM-1 services.

Encapsulation Type Null

Indicates the link layer encapsulation type of the port. It specifies the link layer encapsulation type that can be identified and processed by the port.

When Encapsulation Type is set to Null, no link layer encapsulation is available or the link layer encapsulation is not performed.

The OptiX OSN equipment currently supports only Layer 1 in Port Mode. For this reason, Encapsulation Type can only be set to Null and cannot be changed.

Channelize Yes

Displays whether the port is a channelized port.

Channelize refers to the use of the low-speed tributary signals in the STM-N service. One fiber is used to transmit multiple channels of data that are separated from each other. Each channel of data exclusively occupies the bandwidth, in addition to the starting point, terminating point, and monitoring policy.

Max Data Packet Size (byte) -

Specifies the maximum size of the packets that can be received by the port.

NOTE:

This parameter is currently inapplicable to the OptiX OSN equipment.

Laser Interface Enabling Status

On, Off

Default: On

Specifies the enabling status of the laser on the port.

Laser Transmission Distance(m) -

Displays the transmission distance of the laser on the port.

NOTE:

This parameter is currently inapplicable to the OptiX OSN equipment.

Scrambling Capability -

Suppresses multiple 0s and 1s in the data when the Scrambling Capability is enabled.

NOTE:

This parameter is currently inapplicable to the OptiX OSN equipment.

CRC Check Length -

Specifies the length of the CRC field in the mapping protocol.

NOTE:

This parameter is currently inapplicable to the OptiX OSN equipment.

Clock Mode

-

The Clock Mode parameter specifies the re-timing mode of a port.

NOTE:

This parameter is currently inapplicable to an SDH port.

Loopback Mode

Non-loopback, Inloop, Outloop

Default: Non-loopback

Specifies the loopback status of the port.

The loopback mode is used for locating a fault. Outloop is used for testing whether the port module and external fiber or cable of a board are proper. Inloop is used for testing whether the cross-connect unit and service path of the equipment are proper.

CES Encapsulation Clock Mode

Null, Line Clock Mode, System Clock Mode

Default: Null

Specifies the encapsulation mode of the clock signal on a UNI port on the master side of the CES service.

  • Null: The clock signal is not encapsulated in the service packets.
  • Line Clock Mode: The clock frequency signal extracted on a line port is used as the time stamp, which is encapsulated in the RTP packet header and transmitted to the downstream.
  • System Clock Mode: The system frequency signal is used as the time stamp, which is encapsulated in the RTP packet header and transmitted to the downstream.
CES Encapsulation Clock Poke -

Specifies the enabling status of the CES encapsulation clock poke.

NOTE:

This parameter is currently inapplicable to the OptiX OSN equipment.

Field

Value Range

Description

Service Type

For example, CES service

Displays the type of the service associated with the port.

Service ID

For example, 20

Displays the ID of the service associated with the port.

When you select the value of the service ID, the active window changes to the service management dialog box of the corresponding service type.

Service Name

For example, CES

Displays the name of the service associated with the port.

Used Resource

For example, 64K Timeslot1-31

Displays the resource used by the service associated with the port.

E1 Port

In addition to the general attributes of an E1 port, you need to set the frame format based on the advanced attributes to ensure that the frame format specified for the E1 port is the same as the service encapsulation format.

Field

Value Range

Description

Port

Slot ID-Board name-Port (Port No.)

Displays the port name.

Name

For example, Port 1

Enters the port name specified by the user.

Port Mode

Layer 1, Layer 2

Specifies the working mode of the PDH port.

When this parameter is set to Layer 1, the port can transmit TDM signals.

When this parameter is set to Layer 2, the port can transmit ATM signals.

Encapsulation Type

Null

Specifies Encapsulation Type.

When Port Mode is set to Layer 1, Encapsulation Type is defaulted to Null and cannot be changed.

When Port Mode is set to Layer 2, Encapsulation Type is defaulted to ATM and cannot be changed.

Field

Value Range

Description

Port

Slot ID-Board name-Port (Port No.)

Displays the port name.

Frame Format

Unframe, Double Frame, CRC-4 Multiframe

Specifies the frame format.

When the E1 port transmits CES services in CESoPSN mode, this parameter can be set to Double Frame or CRC-4 Multiframe. It is recommended that you set this parameter to CRC-4 Multiframe. When the CES services are in SAToP mode, this parameter needs to be set to Unframe.

Line Encoding Format

HDB3

Displays the line encoding format.

The HDB3 codes are transmitted on the E1 port.

Clock Mode

Master Mode, Slave Mode, Line Clock Mode

Default: Master Mode

The Clock Mode parameter specifies the re-timing mode of a port.

  • Master Mode: Indicates that the internal clock is adopted.
  • Slave Mode: Indicates that the clock from ACR is adopted.
  • Line Clock Mode: Indicates that the clock from line boards is adopted.

Loopback Mode

Non-loopback, Inloop, Outloop

Specifies the loopback status of the port.

Impedance

120 ohm

Displays the impedance of the port.

Frame Mode

-

Specifies the value of the frame mode.

The frame modes of the local port and opposite port need to be consistent.

CES Encapsulation Clock Mode

Null, Line Clock Mode, System Clock Mode

Default: Null

Queries the encapsulation mode of the clock signal on a UNI port on the master side of the CES service.

  • Null: The clock signal is not encapsulated in the service packets.
  • Line Clock Mode: The clock frequency signal extracted on a line port is used as the time stamp, which is encapsulated in the RTP packet header and transmitted to the downstream.
  • System Clock Mode: The system frequency signal is used as the time stamp, which is encapsulated in the RTP packet header and transmitted to the downstream.
