Release Notes for Cisco ONS 15454 Release 7.0.2
OL-11368-01
New Features and Functionality
particularly well suited for use in networks that employ DS fiber or SMF-28 single-mode fiber. Equipped
with ROADM functionality, the ONS 15454 DWDM can be configured to add or drop individual optical
channels using CTC, Cisco MetroPlanner, and CTM.
A ROADM NE utilizes two 32WSS-L cards (two slots each) and two 32DMX-L cards (one slot each),
for a total of six slots in the chassis. The 32WSS-L card can be installed in Slots 1 and 2, 3 and 4, 5 and
6, 12 and 13, 14 and 15, or 16 and 17.
The 32WSS-L has six types of ports:
• ADD RX ports (1 to 32)
• EXP RX port
• EXP TX port
• COM TX port
• DROP TX port
For more details on the functions of the ports, see the Cisco ONS 15454 DWDM Installation and
Operations Guide.
Several photodiodes monitor the power for the 32WSS-L card. The returned power level values are
calibrated to the ports. See the Cisco ONS 15454 DWDM Installation and Operations Guide for more
details.
32DMX-L Demultiplexer Card
The 32-Channel Demultiplexer L-Band card (32DMX-L) is a single-slot optical demultiplexer. The card
receives an aggregate optical signal on its COM RX port and demultiplexes it into to 32 100-GHz-spaced
channels. The 32DMX-L card is particularly well suited for use in networks that employ DS fiber or
SMF-28 single-mode fiber. The 32DMX-L card can be installed in Slots 1 to 6 and in Slots 12 to 17.
The 32WSS-L has two types of ports:
• COM RX port
• DROP ports (1 to 32)
For more details on the functions of the ports, see the Cisco ONS 15454 DWDM Installation and
Operations Guide.
Several photodiodes monitor the power for the 32WSS-L card. The returned power level values are
calibrated to the ports. See the Cisco ONS 15454 DWDM Installation and Operations Guide for more
details.
CE-1000-4 Card
The CE-1000-4 card, new for Release 7.0.x, uses pluggable Gigabit Interface Converters (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.
