KCMTS-122
DOCSIS CompactCMTS

Knovative’s CompactCMTS is a high-performance, cost-effective and highly integrated DOCSIS Cable Modem Termination System (CMTS). The CompactCMTS is a complete, self-contained DOCSIS CMTS. With its internally integrated Upconverter, DHCP, TFTP and TOD servers everything needed to support DOCSIS cable modem operation is provided. Its compact size and highly integrated design makes the CompactCMTS the most ideal CMTS product for Franchised Cable, Private Cable, MDUs, SMATVs, campuses and hotel operations.

The KCMTS-122 is delivered with software that is fully DOCSIS 1.0 compliant and supports the most frequently used DOCSIS 1.1 features.

The KCMTS-122 support's one downstream and two upstream channels. The mechanical design allows it to be installed on a 19” rack or table/tray (with rack mounting handles removed). All interface cables and LED status indicators are located at the front for easy wiring.

Front Panel Interfaces

• Downstream Output – Provides the QAM64 or QAM256 modulated DOCSIS downstream data.
• Downstream Monitor – for examining the downstream RF signal without interfering with the normal downstream RF signal.
• US1 Input, US2 Input – Accepts QPSK or QAM16 modulated DOCSIS upstream data.
• US1 Monitor, US2 Monitor – for examining the upstream RF signal without interfering with the normal upstream RF signal.
• Network – 10/100BaseT Ethernet (DCE) port that carries data and management packets between the CMTS and the backbone network. Both internal Web Server and Telnet are available through the Console port for accessing the internal DHCP, TFTP servers and CompactCMTS data base for Cable Modem provisioning.
• Console – RS232 serial port for monitor and control of the CompactCMTS using the same commands provided by Telnet. This port can be attached to a standard phone modem for continued access during network connection outages.

Features and Functions

Downstream

• Provides downstream signal at DOCSIS frequency range. There is no need for external upconverter.
• Fully compliant to DOCSIS downstream PHY layer and MAC layer specifications.
• Supports and compliant to DOCSIS BPI/BPI+ security specifications.

Upstream

• Fully compliant to DOCSIS upstream PHY layer specifications including channel equalization.
• Fully compliant to DOCSIS upstream MAC layer specifications including MAP generation, UCD generation, cable modem ranging, MAC de-framing, frame error detection, MAC message extraction and PDU frame deconcatenation.
• Supports and compliant to DOCSIS BPI/BPI+ specifications.

Network

• Layer-2 bridging, supports DOCSIS spanning-tree protocol.
• Flexible CM provisioning using either internal DHCP, TFTP servers or optional external servers.
• Built-in Time-of-Day server for cable modem support.
• Supports DOCSIS IGMP Proxy and IP Multicast.

Operational Support System (OSS)

• Native CMTS control/status
  • Intuitive built-in Web Server. Use standard Internet Explorer or other web browser to access. Different access control groups for monitoring, setup or administration.
  • SNMP MIBI/II access supports both DOCSIS standard and Private MIBs.
  • Telnet access
  • Consol port access
• Provisioning similar to DOCSIS cable modem provisioning
• DHCP client retrieval of CMTS IP address, handle to CMTS configuration file.
• TFTP client retrieval of CMTS configuration file, software/firmware update files.
• Internal DHCP, TFTP and Time of Day Servers make this a standalone system. DHCP can provide either IP address pools or static IP address assignment to both CMs and CPEs.
• Provisioning can also forward DHCP/TFTP to external servers in full compliance with DOCSIS requirements.
