1 Overview
This guide is designed to help you quickly set up and use your Cisco 1040 Sensor (Cisco 1040). A
Cisco 1040 is a shelf-top unit that connects to the network and obtains Power over Ethernet (PoE)
through a Cisco Catalyst switch. It is easy to connect your Cisco 1040. These sections explain what a
Cisco 1040 does and how it fits in with products in the Cisco Unified Communications Management
Suite:

Cisco 1040s and Cisco Unified Operations Manager, page 2

Cisco 1040s and Cisco Unified Service Monitor

Cisco 1040s listen to Real-Time Transport Protocol (RTP) voice traffic on a Switch Port Analyzer
(SPAN) port that you must configure to mirror voice traffic on phone ports or voice VLANs.
Cisco 1040 calculates Mean Opinion Scores (MOS) and sends data at 60-second intervals to Cisco
Unified Service Monitor (Service Monitor), a product from the Cisco Unified Communications
Management Suite.
Service Monitor examines the MOS value and compares it against a user-specified threshold value for
the codec in use on the call. When MOS drops below the threshold, Service Monitor generates SNMP
traps and sends them to up to four recipients. A single Service Monitor can receive and analyze MOS
data from multiple Cisco 1040s. If you have more than one Service Monitor, you can configure
Cisco 1040s to fail over to a secondary service monitor. For more information, see User Guide for
Cisco Unified Service Monitor.

Cisco 1040s and Cisco Unified Operations Manager

You can use Cisco Unified Operations Manager (Operations Manager) to further analyze, display, and
act on the traps that Cisco 1040 generates. When configured as a trap recipient from Service Monitor,
Operations Manager generates service quality events, displays and tracks these events on a real-time
dashboard, and displays and stores event history. You can configure additional event settings on
Operations Manager that alert you to low MOS and to the occurrence of many service quality events
during a period of time. In addition, you can configure Operations Manager to send notifications by
e-mail, SNMP trap, and syslog message.
