CATV network testing simplified
A next generation CATV installer meter to characterize and measure Analog and Digital video signals. For Analog carriers, Peak Video level, single or dual channel Audio levels and Carrier to Noise (C/N) measurements are possible on NTSC, PAL, or SECAM video formats. Digital QAM16/64/256 carriers with or without deep Interleaving are measured accurately with MER, BER and Constellation diagram results being reported. Tilt, Quick Test, and Forward/Reverse ingress scan are standard features. The built-in Ethernet port supports Triple Play test features, such as VoIP call emulation with MOS scoring, Web-browser, IP connection testing, remote control, test results upload/download, and system management. WiFi connectivity tests can be performed using a USB WiFi adaptor.

The CX110+ is equipped with a built-in DOCSIS cable modem, which discovers the upstream frequencies by listening on the downstream channel for Upstream Channel Descriptor (UCD) packets. Once a special message called a map is detected, the cable modem begins to transmit upstream data starting at its lowest power level, incrementing in 3dB steps until the CMTS acknowledges the request.

Once detected, the CMTS analyzes the power, frequency and timing of the range request and send the cable modem a response which provides instructions for the modem to adjust its transmit power, frequency and timing to operate properly on the network. The upranging check functionality is very useful for technicians who are only concerned with the RF alignment and synch process when installing cable modems.

Features

Single Channel Measurement
Analog and digital carriers are very different in terms of signal content and power distribution and thus require the advanced SLM techniques supported in the VePAL CX series.

In analog mode, video and audio levels, V/A, Carrier to Noise (C/N) and Adjacent channels are measured. In digital mode, average power, MER, Pre-BER, Post-BER, Error seconds, and constellation diagram are displayed. User programmable location thresholds and test point compensation are useful utilities enabling fast, simple and automated testing of carrier signals.

Digital pictures do not show signal impairment until it is too late because the margin between acceptable quality and failure is quite small.

Constellation diagrams are a valuable tool to help detect the presence of noise, phase jitter, interference and gain compression, all of which impact overall signal quality and thus reduces Modulation Error Ratio (MER). Ideally, each of the 64 or 256 symbols should display a clean dot indicating a perfect QAM signal. Therefore, the size and shape build up of dots is indicative of problems which contribute to bit errors and even service disruption.

Installation Check
For new installations, up to six analog and six digital channels are checked against preset location thresholds. The feature is particularly useful to verify and turn up of service at new installations or after service is restored, Pass and fail conditions are color coded for easy interpretation and test results are clearly displayed. This automatic test procedure adds consistency to the final service qualification. A zoom function provides data measurement in greater detail. The VePAL CX series can store up to 20 channel tables each of which can be pre-programmed with channels to be used for installation check.

Tilt
Tilt measurements identify distortion over the frequency range allowing technicians to apply correct equalization or compensation to the HFC network. Up to 12 analog signals and digital carriers including DOCSIS channels can be predefined on a channel table and selected to perform the tilt measurement. The measurement can be performed between the lowest and highest channel or any user selectable channel by tapping the applicable bar on screen.

System Scan
Within seconds, all analog and digital channels at a service location are measured. Signal parameters including channel number, channel name, frequency, modulation type and power levels are measured.

Signal degradation or tilt can be easily pinpointed using onscreen markers and the zoom mode.

Forward/Reverse Path Ingress Scan
Poorly shielded coaxial cable and fault terminations (CPD) are sources and causes of ingress noise. Ingress is troublesome for return path communications in CATV networks due to the large number of subscriber-generated signals being funneled towards the headend. The combined and amplified interference is often responsible for service disruption, therefore the ingress test is a valuable tool to check the forward and reverse paths for interference and related problems.

Advanced IP Testing
Triple Play services are IP centric, so IP test functions are no longer considered a luxury. On a daily basis, technicians verify network connections during service installation and restoration, so Ping test, Trace Route, ARP, Web browser, FTP throughput, VoIP Call emulation and IPTV measurement have become routine measurements. IP verification on the CX series is possible over the DOCSIS Cable Modem and 10/100Base-T Ethernet test ports, while a subset of these tools is available using the USB WiFi adaptor.

Results and Events
Results mode displays a systematic, yet intuitive summary of the most significant modem connection parameters. At a mere glance, the technician can quickly identify whether the ranging and/or registration process has failed or passed. Events mode not only logs and displays a time stamped sequence of the CMTS connection process, but also records link failures and modem retrains. If service activation or fast troubleshooting are your daily priorities, both features will prove to be indispensable.

IPTV Service Verification
Designed and optimized for technicians turning up IP video service. Set-Top Box (STB) emulation includes registration, IGMP and RTSP signaling for Broadcast and Video on Demand (VOD) applications. Transport stream analysis encompasses data/ video/audio bit rates and Program Identification (PID) mapping. Packet jitter and loss, IGMP latency (channel zapping), PCR statistics and Viewer function complete the Video Quality of Service (QoS) application suite.

VoIP Testing
Take advantage of the three separate software options offering different test methods to verify and provision your VoIP network. Testing can be performed over any of the Ethernet or DOCSIS test ports.

VoIP Check – Simulates a VoIP call to the nearest router and measures the round trip MOS score and related VoIP parameters.

VoIP Expert – Generates industry standard wave files to verify MOS and R-Factor values of upstream and downstream paths and includes QoS measurements such as packet jitter, packet loss, and delay.

VoIP Call Expert – Emulates an IP phone and can place and receive calls using SIP or H.323 protocols. Comprehensive Codex support and call destination options verify voice encoding and translation provisioning. Real-time evaluation of subjective voice quality (MOS and R-factor) is made possible using the patented Telchemy test method which has been integrated into all VePAL test sets.

Net Wiz
Ethernet network installation is simplified using this basic, yet powerful feature. A built-in TDR identifies distance to short, distance to open, wire cross, and other anomalies associated with CAT-5 structured cabling. “Sniff” the network using the onetouch discovery feature. Identify routers, gateways, printers, PCs and other devices connected to the network within seconds.

WiFi Wiz
All VePAL products adopt a USB WiFi adaptor to make 802.11 b/g wireless installations a simple task. Scan for available networks or perform signal strength and quality measurements to determine the best location for a new wireless access point. The IP Ping capability ensures the wireless network is properly installed and configured. A full suite of IP testing features is supported.

ReVeal CX Server Productivity Suite
A software application specifically designed for medium-to-large CATV operators facing the enormous challenge of coordinating hundreds of installations per day, collecting the field test results for billing/record purposes and having to maintain a large inventory of test sets in parallel. When used in conjunction with the Home Installation Process (HIP) and Signature Pad features, the application becomes a powerful tool to reduce customer call-backs and associated truck rolls, maximizing workforce efficiency and lowering operational costs. ReVeal

Advanced Management

PAYLOAD MAPPINGS SUPPORTED
(PER Bellcore GR.253 RECOMMENDATIONS)

The SONET Multiplexing principle basically consists of:

  • Mapping – Tributaries are adapted into STS Synchronus Payload Envelope (STS SPE) by adding justification bits and STS Path Overhead (POH)
  • Aligning – Addition of a Pointer to a Virtual Tributary (VT) and STS-Ns for identification of the STS SPE
  • Multiplexing – Virtual signals are adapted into STS path signals are multiplexed

The TX150 tests the proper operation of Add/Drop Multiplexers, Digital Cross Connects and other Network Elements (NE) by verifying the mapping and de-mapping of different tributaries and payloads into SONET containers and monitors anomalies and defects associated with each process. The Payload and Path Overhead of each SONET SPE including the Pointer associated with the DSn tributary can also be monitored. Mapping of full bandwidth services e.g. IP, Multimedia and ATM is possible using concatenated payloads.

QUICK AND EASY GRAPHICAL SETUP
Encountering a variety of complex daily tasks is common in today’s network environment, so technicians need a tester that is easy to configure and which doesn’t require extensive product training beforehand. Respecting these issues, the test interface, signal structure, payload mapping and test pattern setup boxes are structured logically so that the user can quickly and efficiently configure the unit via an intuitive graphical menu.

A list of shortcuts provides fast access to commonly used SONET or DSn test functions boosting productivity.

PHYSICAL LAYER TESTING
Before performing any digital measurements, first confirm that analog parameters are within prescribed specifications and limits. Very high optical power levels can saturate or even damage receivers, while low power levels are susceptible to noise which may in turn cause bit errors.

Clock frequency offset error is another analog parameter which is often overlooked. A series of clock tolerances for each signal hierarchy is clearly defined by Bellcore/ITU-T recommendations and should be verified as part of any acceptance/conformance test.

PERFORMANCE ANALYSIS SUMMARY
Performance of each hierarchy is based on byte interleaved parity (BIP) checksums which are calculated on a frame by frame basis. These BIP checks are inserted into the Regenerator, Multiplexer and Path Overhead all of which form an integral part of the performance monitoring capabilities of an SONET network.

The TX150 summary screen quickly shows Pass/Fail criteria for each performance parameter according to ANSI/Bellcore/ITU-T recommendations where applicable.

ERRORS AND ALARMS
The SONET frame structure contains a large amount of overhead, some being associated with alarms and in-service monitoring. Major alarm conditions such as LOS, LOF and LOP cause Alarm Indication Signals (AIS) to be sent downstream which in turn generate alarm signals in the upstream direction in a response to AIS detection.

Anomalies (Errors) and Defects (Alarms) are clearly displayed and recorded for each network segment by the TX150, and are logged for further analysis.
