5.12 CE-1000-4 Card
The CE-1000-4 card uses pluggable GBICs to transport Ethernet traffic over a SONET 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 SONET mapper with four virtual
ports to transfer Ethernet packets over a SONET 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 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:
–
–
Contiguously concatenated (CCAT) SONET payloads:
•
–
–
To configure a CE-1000-4 card SONET STS or VCAT circuit, refer to the "Create Circuits and Tunnels"
chapter in the Cisco ONS 15454 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.
•
Adding or removing cross connects from the VCG is not service affecting if the associated members
are not in group.
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).
The following guidelines apply to fixed VCGs:
Members can be added or removed from VCGs using CTC or TL1.
•
•
Members cannot be put into or out of service unless the force command mode is instantiated.
