Is a CMTS a modem?
A cable modem termination system (CMTS) is a component that exchanges digital signals with cable modems on a cable network. A cable modem termination system is located at the local office of a cable television company.
What would be the physical connectivity between CMTS and cable modem?
CMTS has both radio frequency interfaces and Ethernet interfaces. It transmits and receives user data packets to and from the cable modem attached to the subscriber through HFC network. It then converts them to Internet Protocol packets (IP packets) and routes them to the concerned Internet Service Provider (ISP).
What is the difference between CMTS and CCAP?
The CCAP Core contains both a CMTS Core for DOCSIS and an EQAM Core for Video. The CMTS Core contains the DOCSIS MAC and the upper layer DOCSIS protocols. This includes all signaling functions, downstream and upstream bandwidth scheduling, and DOCSIS framing.
What technology uses CMTS?

What is Mer in cable?
The modulation error ratio or MER is a measure used to quantify the performance of a digital radio (or digital TV) transmitter or receiver in a communications system using digital modulation (such as QAM).
How does the CMTS store information about cable modems and CPE?
The CMTS stores information about Cable Modems and CPEs in an internal database so that CLI commands, such as show cable modem and show interface cable X/Y modem Z, as well as SNMP queries, are able to reveal information about the Cable Modems and CPE.
How do I remove a CPE device from a CMTS?
A CPE device will remain as an entry in a Cisco CMTS’s internal databases until it’s ARP entry expires or it is removed using the clear cable host command. In addition, if the Cable Modem a CPE device is associated with is removed, then the CPE device will be removed as well.
How do I synchronize Max-CPE with the CMTS?
When the cable modem initializes, the only time it can synchronize MAX-CPE with the CMTS is when it sends the MAX-CPE count to the CMTS in the registration request flow. If the cable modem is reloaded, there is no flow to the CMTS to inform it to reduce the CPE’s allocated count to zero.
