17. Safety Information for ARRIS Touchstone Products ARRIS telephony modems and cable modems comply with the applicable requirements for performance, construction, labeling, and information when used as outlined in this Section 17:

17.1 Caution: Only a professional installer may connect the telephony modem to the homes existing telephone wiring. Physical connections to the previous telephone provider must be removed and the wiring must be checked; there must not be any voltages. Cancellation of tele-phone service is not sufficient to ensure there is no power to the telephony modem. Failure to do so may result in loss of service and/or permanent damage to the telephony modem.

17.2 Do not use the product near water (e.g., wet basement, bathtub, sink or near a swimming pool), to avoid risk of electrocution.

17.3 Avoid using and/or connecting the equipment during an electrical storm, to avoid risk of electrocution.

17.4 Do not locate the product within 6 feet (2 m) of a flame or ignition source, to avoid damage or injury from battery explosion, or heat damage.

17.5 Use only the power supply and/or power cord included with the Product. Install the Product near and easily accessible to the power outlet. Ground the RF drop cables shield at the building/residence either close to the point of entrance or at the point of attachment. Grounding as close as practical to the building/residence AC ground is required to minimize grounding con-nector length and thereby limit the potential voltage differences between the cable TV coaxial cable and other grounding system. Refer to the individual countrys National Electric Code for further details.

17.6 In areas of high AC power surge events or poor AC power grounding situations and areas prone to lightning strikes additional AC power surge protection may be required on the AC, RF, Ethernet, USB and phone lines.

17.7 If connecting the telephony modem or cable modem to a local computer through the Ethernet or USB cable the computer must be properly grounded to the building/residence AC ground network. All plug-in cards within the computer must be properly installed and grounded to the computer frame per the manufacturers specifications.

In response to emerging IP-based data and voice services, ARRIS brings to market a next-generation, carrier-class Cable Data Network Solution the Cadant C4 Cable Modem Termination System (CMTS). As of January 2006 there are more than 1000 C4 CMTSs in the field. They support well over 5 million subscribers on four continents.

The C4 CMTS has been designed to meet the needs of the Multiple System Operator (MSO) in terms of system density, wire-speed performance, and reliability.

This chapter introduces the C4 CMTS and its features, functionality, and components. This chapter contains the following topics:

Descriptive and reference information

Features list

DOCSIS 2.0 Compliance

In December, 2004, the Cadant C4 Cable Modem Termination System (CMTS) received DOCSIS 2.0 requalification by CableLabs with the new software upgrade designed to support DOCSIS Set-top Gateway (DSG) technology. With this qualification, the Cadant C4 CMTS, configured with the higher density 2Dx12U CAM provides the most reliable and scalable CMTS solution currently available. Using it, MSOs can provide their customers with advanced voice and high-speed data solutions.


2 C4 CMTS Features

The Cadant C4 CMTS supports DOCSIS Set-Top Gateway (DSG), allowing operators to transition the signaling, provisioning and control of advanced set-top boxes from proprietary to standards-based protocols. This transi-tion of all services to IP-based standards is expected to streamline opera-tions and lower capital costs for cable operators.

The DOCSIS 2.0 standard greatly improves performance in the upstream path of the cable network. The growing demand for peer-to-peer file sharing, interactive gaming, and voice over IP telephony increases the need for upstream bandwidth.

The following enhancements are available to CMTSs and CMs that comply with the 2.0 standard while maintaining all the DOCSIS 1.1 and 1.0 func-tionality:

Enhanced upstream capacity

Greater maximum upstream throughput up to 30.72 mbps per channel

Greater upstream channel width up to 6.4 Mhz

New upstream channel modulation rates: 8QAM, 32QAM, and 64QAM

Longer preamble to facilitate synchronization up to 1536 bits

Higher powered preamble QPSK-1

Enhanced noise cancellation and error correction

Synchronous-Code-Division Multiple Access (SCDMA) operation along with the standard TDMA and ATDMA techniques for combining CM signals onto a given upstream channel.

Fault Detection and Recovery

The C4 CMTS employs:

Advanced data-path integrity checks (parity, CRC, loopbacks, pings)

Continuous system audits

Multiple levels of error detection.

Fault recovery on the C4 CMTS:

Rapidly isolates faults

Decreases diagnostic and repair time

Reduces the probability of fault propagation

Minimizes impact on subscriber services.


C4 CMTS

Interfaces and Protocols

Open interfaces and protocols allow seamless integration with existing network management infrastructures. The primary protocols supported by the C4 CMTS include the following:

Simple Network Management Protocol (SNMP) v1, v2c, and v3

DOCSIS 1.1, DOCSIS 2.0 and Cadant MIBS

Command Line Interface (CLI)

File Transfer Protocol (FTP)

Telnet

Routing Information Protocol (RIPv2)

Open Shortest Path First (OSPF
