Release Notes for Cisco ONS 15454 Release 7.0.2
OL-11368-01
New Features and Functionality
CE-1000-4 card Ethernet frames are encapsulated using the ITU-T generic framing procedure (GFP)
(with or without CRC) or LEX, the point-to-point protocol (PPP) with high-level data link control
(HDLC). The CE-1000-4 card can interoperate with G1000-4/G1K-4 cards (using LEX encapsulation),
CE-100T-8 cards (using LEX or GFP-F), and ML-Series cards (using LEX or GFP-F).
The Ethernet frames can be mapped into:
• T1X1 G.707-based high-order virtual concatenated (HO VCAT) payloads
• STS-3c-nv where n is 1 to 7
• STS-1-nv where n is 1 to 21
• Contiguously concatenated (CCAT) SONET payloads
• Standard CCAT sizes (STS-1, STS-3c, STS-12c, STS-24c, STS-48c)
• Non-standard CCAT sizes (STS-6c, STS-9c, STS-18c)
The CE-1000-4 card provides multiple management options through Cisco Transport Controller (CTC),
Cisco Transport Manager (CTM), Transaction Language 1 (TL1), and Simple Network Management
Protocol (SNMP).
The CE-1000-4 card supports the software link capacity adjustment scheme (SW-LCAS). This makes it
compatible with the ONS 15454 CE-100T-8 and ML-Series cards. The CE-1000-4 card supports VCAT
groups (VCGs) that are reconfigurable when SW-LCAS is enabled (flexible VCGs). The CE-1000-4 card
does not support the standard hardware-based LCAS. For specific guidelines that apply to flexible VCGs
consult the user documentation.
The CE-1000-4 card supports a non link capacity adjustment scheme (no-LCAS). This also makes it
compatible with the ONS 15454 CE-100T-8 and ML-Series cards. The CE-1000-4 card supports VCAT
groups (VCGs) that are fixed and not reconfigurable when no-LCAS is enabled (fixed VCGs). For
specific guidelines that apply to fixed VCGs consult the user documentation.
The CE-1000-4 card supports VCAT differential delay and provides these associated features:
• Supports a maximum VCG differential delay of 122 ms in each direction.
• Supports all protection schemes (UPSR, two-fiber BLSR, four-fiber BLSR) on VCAT circuits that
are split-fiber routed.
• Supports 2-fiber on VCAT circuits that are common-fiber routed.
• Differential delay compensation is automatically enabled on VCAT circuits that are diverse (split
fiber) routed and disabled on VCAT circuits that are common-fiber routed.
For CE-1000-4 Card-Level Indicators, Port-Level Indicators, and Cross-Connect and Slot Compatibility,
consult the user documentation.
MS-ISC-100T Card
The Multishelf Internal Switch Card (MS-ISC-100T) is an Ethernet switch used to implement the MSTP
multishelf LAN. It connects the node controller shelf to the network and to subtending shelves. The
MS-ISC-100T must always be equipped on the node controller shelf; it cannot be provisioned on a
subtending controller shelf.
Cisco recommends that you configure the node to implement LAN redundancy, using two MS-ISC-100T
cards: one switch is connected to the Ethernet front panel port of the TCC2/TCC2P card in Slot 7, and
the other switch is connected to the Ethernet front panel port of the TCC2/TCC2P card in Slot 11. The
Ethernet configuration of the MS-ISC-100T card is part of the software package and is automatically
