CE-MR-6 Ethernet Card
This section describes the operation of the CE-MR-6 card supported on the ONS 15310-MA. The
CE-MR-6 card installed in ONS 15310-MA is restricted to SONET operations.
Provisioning is done through Cisco Transport Controller (CTC) or Transaction Language One (TL1).
Configurations through Cisco IOS terminal are not supported on the CE-MR-6 card.
For Ethernet card specifications, refer to the Cisco ONS 15310 Reference Manual. For step-by-step
Ethernet card circuit configuration procedures, refer to the Cisco ONS 15310 Procedure Guide. Refer to
the Cisco ONS SONET TL1 Command Guide for TL1 provisioning commands.

CE-MR-6 Overview
CE-MR-6 card is a 5 Gbps data module for use in the Cisco ONS 15310-MA. It provides support for L1
packet mapping functions (Ethernet to SONET). The 10/100/1000 Mbps Ethernet-encapsulated traffic is
mapped to SONET circuits. Each circuit has three main attributes:
•
Low order or high order
•
Contiguous concatenation (CCAT) or virtual concatenation (VCAT)
•
Generic framing procedure (GFP), LEX, high-level data link control (HDLC), or
PPP (point-to-point protocol) based framing.
The CE-MR-6 cards support LCAS that allows hitless dynamic adjustment of SONET link bandwidth.
The CE-MR-6 is a Layer 1 (Ethernet Private Line) and Layer 1+ (Virtual Private Wire Services) mapper
card with six IEEE 802 compliant 10/100/1000 Mbps Ethernet ports that provide 1:1 mapping of
Ethernet ports to circuits. It maps each port to a unique SONET circuit in a point-to-point configuration.
Figure 17-6 illustrates a sample CE-MR-6 application. In this example, data traffic from the Fast
Ethernet port of a switch travels across the point-to-point circuit to the Fast Ethernet port of another
switch.

The CE-MR-6 card allows you to provision and manage an Ethernet private line service like a traditional
SONET line. CE-MR-6 card applications include providing carrier-grade Ethernet private line services
and high-availability transport.
The CE-MR-6 card carries any Layer 3 protocol that can be encapsulated and transported over Ethernet,
such as IP or IPX. The Ethernet frame from the data network is transmitted on the Ethernet cable into
the 10/100/1000 Mbps Ethernet ports on a CE-MR-6 card. The CE-MR-6 card transparently maps
Ethernet frames into the SONET payload using packet-over-SONET/SDH (POS) encapsulation. The
POS circuit, with its encapsulated Ethernet inside, is then multiplexed onto an optical card like any other
