The Cisco Network
Convergence System (NCS) 1001 is a 1 RU chassis that addresses the growing
bandwidth needs of data center DWDM applications. It provides a DWDM line
system that is optimized for data center environments and is optimized for
point-to-point applications at maximum capacity. Cisco NCS 1001 supports up to
three optical modules. The modules can be amplifiers or protection switching
NCS 1001 has the
Four removable fans.
Two removable AC or DC power supply modules (PSU).
Three slots for optical modules. The Optical Amplifier Module ( NCS1K-EDFA) and Protection Switching Module (NCS1K-PSM) can be inserted in these slots.

in Release 6.2.1
Optical Amplifier Module
The optical amplifier module (NCS1K-EDFA) has pre-amplifier and
The optical amplifier module provides the following functionality.
Preamplifier (LINE-RX to COM-TX) - Single preamplifier variant,
with switchable gain ranges, according to link loss:
Range # 1: 0 to 24 dB gain, Tilt control: 24 to 27 gain, with
Range # 2: 20 to 34 dB gain, Tilt control: 34 to 37 dB gain,
with tilt uncontrolled
23dBm output power @ COM-TX port
Booster amplifier (COM-RX to LINE-TX) - True variable gain booster
Gain range: 1 to 20. 20 to 25 uncontrolled tilt.
23dBm output power @ LINE-TX port
ADD/DROP OSC channel supports both 1510nm and 1610nm +/-10nm
OCM assesses channel presence and Gain regulation and per channel
Protection Switching Module
The protection switching module (NCS1K-PSM) provides the following
In TX section:
Splits input optical channels to both working and protection
Forces the switch in the remote site by opening one of the two
line paths (by putting the related VOA in AVS).
In RX section:
Selects the signals from working or protection line. Each line
is monitored through a PD.
Balances the two line losses by changing the VOA attenuation
value at the same time of the switch change of state.
The Optical Transport Section (OTS) controller holds all the optical
parameters for the OTS optical interfaces. The optical interface has different
capabilities depending on its hardware components such as photodiode, VOA,
amplifier, and OCM. Hence, the parameters enabled or disabled on the OTS
controller depend on the actual hardware capability on the specific optical
interface. Each parameter might refer to RX or TX section. For example, if a
photodiode is present, the OTS controller can read the total optical power.
When the controller is created, each hardware capability is enabled or
OTS OCH Controller
The Optical Transport Section OCH (OTS OCH) controller represents the
OCM device available on the OTS optical interface. This controller is created
to have channel granularity over the OTS interface. The OTS OCH controller
contains the wavelength information. The controller number starts from 1 and
matches with the ITU channel identifier.
Cisco NCS 1001 provides comprehensive management capabilities to
support operations, administration, maintenance, and provisioning (OAM&P)
capabilities through IOS-XR CLI, SNMP, Syslog, and XML. In addition, iPXE for
automated software download and Zero Touch Provisioning (ZTP) for automated
configuration download are available for simplified installation. For Machine
to Machine configuration and management of NCS 1001, NETCONF, RESTCONF and gRPC
transport mechanisms with JSON, XML and GPB encoding are provided. NCS 1001
provides a set of native YANG models as well as the ability to map into any
industry standard or customer defined YANG models. For monitoring, NCS1001
provides a streaming telemetry feature that relies on a push mechanism to
disseminate user selected PM and status information at user specified
frequencies at granular 30 second intervals. This improves monitoring speed and
scale compared to traditional pull based mechanisms such as SNMP.
Cisco NCS 1001 supports both transparent and nontransparent signal
transport performance monitoring. Performance monitoring of optical parameters
on the client and DWDM line interface includes Loss of Signal (LOS) and
transmit and receive optical power - both aggregate and per channel.
Calculation and accumulation of the performance-monitoring data are supported
in 15-minute and 24-hour intervals as per G.7710.
