2. DOCSIS - Wikipedia

   en.wikipedia.org/wiki/DOCSIS

   Upstream: Upstream data uses QPSK or 16-level QAM (16-QAM) for DOCSIS 1.x, while QPSK, 8-QAM, 16-QAM, 32-QAM, and 64-QAM are used for DOCSIS 2.0 and 3.0. DOCSIS 2.0 and 3.0 also support 128-QAM with trellis coded modulation in S-CDMA mode (with an effective spectral efficiency equivalent to that of 64-QAM). DOCSIS 3.1 supports data modulations ...

3. Cable modem - Wikipedia

   en.wikipedia.org/wiki/Cable_modem

   DOCSIS 2.0 added support for S-CDMA PHY, while DOCSIS 3.0 added IPv6 support and channel bonding to allow a single cable modem to use concurrently more than one upstream channel and more than one downstream channel in parallel. Virtually all cable modems operating in the field today are compliant with one of the DOCSIS versions.

4. Point-to-Point Protocol over ATM - Wikipedia

   en.wikipedia.org/wiki/Point-to-Point_Protocol...

   In computer networking, the Point-to-Point Protocol over ATM (PPPoA) is a layer 2 data-link protocol typically used to connect domestic broadband modems to ISPs via phone lines. It is used mainly with DOCSIS and DSL carriers, by encapsulating PPP frames in ATM AAL5. Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) is specified by ...

6. Link aggregation - Wikipedia

   en.wikipedia.org/wiki/Link_aggregation

   Under DOCSIS 3.0, up to 32 downstream and 8 upstream channels may be bonded. [25] These are typically 6 or 8 MHz wide. DOCSIS 3.1 defines more complicated arrangements involving aggregation at the level of subcarriers and larger notional channels. [26]

7. Cable modem termination system - Wikipedia

   en.wikipedia.org/wiki/Cable_modem_termination_system

   Cable modem termination system. A cable modem termination system (CMTS, also called a CMTS Edge Router) [1] is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers.
