5.9.3 CE-100T-8 Compatibility
The CE-100T-8 card operates in Slots 1 to 6 or 12 to 17 and operates with the XC-VXL-2.5G,
XC-VXL-10G, or XC-VXC-10G cards.
5.10 CE-1000-4 Card
Note For hardware specifications, see the “A.7.3 CE-1000-4 Card Specifications” section on page A-45.
The CE-1000-4 card uses pluggable Gigabit Interface Converters (GBICs) to transport Ethernet traffic
over a SDH network. The CE-1000-4 provides four IEEE 802.3-compliant, 1000-Mbps Gigabit Ethernet
ports at the ingress. At the egress, the CE-1000-4 card provides an integrated Ethernet over SDH mapper
with four virtual ports to transfer Ethernet packets over a SDH network.
The Ethernet ports automatically configure to operate at either half or full duplex and can determine
whether to enable or disable flow control. The Ethernet ports can also be oversubscribed using flow
control.
The 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:
• Virtual concatenated (VCAT) payloads: VC-4-nv where n is 1 to 7.
Note The CE-1000-4 card does not support VC-3 member sizes.
• Contiguously concatenated (CCAT) SDH payloads: VC-4, VC-4-2c, VC-4-3c, VC-4-4c, VC-4-6c,
VC-4-8c, and VC-4-16c.
To configure a CE-1000-4 card SDH circuit, refer to the “Create Circuits and Low-Order Tunnels”
chapter of the Cisco ONS 15454 SDH Procedure Guide.
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.
The following guidelines apply to flexible VCGs:
• Members can be added or removed from VCGs.
• Members can be put into or out of service.
• Cross-connects can be added or removed from VCGs.
• Errored members will be automatically removed from VCGs.
• Adding or removing members from the VCG is service affecting.
