Release Notes for Cisco ONS 15454 Release 7.0.2
OL-11368-01
New Features and Functionality
An Optical Channel Network Connection (OCHNC) is an optical circuit from an optical channel card to
an optical channel card. Wavelength is the primary characteristic. OCHNCs are the legacy optical
channel circuit type used in situations when OCH trails are not supported. OCHNCs are also used to
carry wavelengths from non-ONS 15454 equipment.
Optical Channel Client Connection Functionality
Optical Channel Client Connections (OCHCCs) support SONET/SDH, Ethernet, FC/FICON, data
storage (including ESCON), video, and passthrough (other) payload types. For specific payload rates,
consult the user documentation.
You can upgrade existing OCHNCs created in earlier software releases to OCHCCs using the Circuits >
Upgrade OCHNC option.
You can create DWDM OCHCCs by assigning port names, creating and verifying PPCs, verifying
OCHCC client ports, and provisioning optical channel client connections as needed; or delete existing
OCHCCs by deleting the associated optical channel network connections.
You can verify the provisionable patchcords (PPCs) that are required between client and optical channel
nodes for OCHCCs using the Provisioning > Provisionable Patchcords (PPC) tabs.
When creating OCHCC circuits, on the Attributes page, you can define the following client circuit
attributes:
• Name—Assign a name to the OCHCC. The name can be alphanumeric and up to 48 characters
(including spaces). Circuit names should be 44 characters or less if you want the ability to create
monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
• Type—(Display only) OCHCC.
• Size—Defines the circuit payload type and rate. Two fields are provided. The first specifies the
payload type. Choose a payload type, then choose the rate in the next field. The payload type and
rate must match the PPM provisioning on the client cards at the source and destination nodes.
• OCHNC Wavelength—Provides three fields to define the wavelength that the OCHCC will use to
travel across the OCH network. Choose a wavelength from the first field. In the second field, you
can change the wavelength band by choosing either C Band or L Band. In the third field, you can
indicate whether odd or even C-band or L-band wavelengths are displayed.
• Bidirectional—(Display only) OCHCCs are bidirectional. This field cannot be changed.
• State—Provisions the OCHCC state. The state can be IS (ANSI)/Unlocked (ETSI) or
OOS,DSBLED (ANSI)/Locked,Disabled (ETSI).
• Apply to OCHCC ports—If checked, applies the state chosen in the next field to the OCHCC client
ports. For TXP, MXP, TXPP, or MXPP cards, this will be the client and all trunk ports. For ITU line
cards, this will be the trunk port only. The states that you can apply include: IS (ANSI)/Unlocked
(ETSI), OOS,DSBLED (ANSI)/Locked,Disabled (ETSI), and IS,AINS
(ANSI)/Unlocked,AutomaticInService (ETSI).
• Protection—Check this box if the source and destination client cards are TXPP or MXPP cards.
Checking the box restricts the source and destination choices to those cards and allows you to
provision the reversion parameters.
• Reversion—If Protection is checked, checking this box turns on the TXPP or MXPP reversion
parameter.
• Reversion Time—If Reversion is checked, set the time before the protection will switch to the active
port after conditions that caused the switch are remedied.
• G.709 OTN—If checked, enables the ITU-T G.709 optical transport network on the client cards, if
permitted by the client card and payload.
