CISCO-CABLE-WIDEBAND-MIB: View SNMP OID List / Download MIB

This is the MIB module for the support of Channel Bonding Protocol for the Cable Modem Termination System (CMTS). Wideband DOCSIS is a method of increasing downstream bandwidth by simultaneously transmitting DOCSIS data over multiple RF channels. This DOCSIS data is organized as a sequence of 188-byte MPEG-TS data packets. A Wideband CMTS (WCMTS) is a CMTS that also transmits Wideband MPEG-TS packets. An Edge QAM (Quadrature Amplitude Modulation) device is one which provides the QAM and used to couple the Wideband MPEG-TS packet onto the HFC plant. A Wideband Cable Modem (WCM) is a CableModem (CM) that is able to receive Wideband MPEG-TS packets. A wideband channel or Bonded Group (BG) is a logical grouping of one or more physical RF channels over which MPEG-TS packets are carried. Wideband channel carries DOCSIS bonded packets encapsulated in MPEG-TS packets from a WCMTS to one or more WCMs. Packets outgoing from WCMTS to the WCM are formatted with the DOCSIS Header. The DOCSIS packets are then formatted into MPEG-TS data packets. These are 188 byte MPEG packets containing the DOCSIS information. Within DOCSIS Header of the WB Channel there is an extended header called, DOCSIS Bonding Extended Header, the format of which is shown below: -------------------------------------------------------- | ---------------------------------------------------- | | | TYPE | LEN | BSID | SEQ | | ---------------------------------------------------- | | | byte 0 | byte 1-2 | byte 3-4 | |--------------------------------------------------------| DOCSIS Bonding Extended Header BSID is the Bonding Service IDentifier, it defines a sequence number for a Wideband channel. It is used by the WCM to re-sequence packets received over downstream channels to maintain packet order. SEQ is per service flow sequence number. Whereas TYPE is the type of the Bonding Extended Header and LEN specifies its length. A Narrowband Channel is a standard DOCSIS downstream channel which contains exactly one RF channel. The wideband protocol utilizes the existing narrowband downstream channel for carrying the MAC management and signaling messages and the associated narrowband upstream for return data traffic and signaling. The channel bonding protocol supports multiple wideband bonded groups. This will allow the WCM to listen to multiple bonded groups at the same time. This would support (for example) multicast video being sent to a CPE device on the LAN side of the WCM in addition to standard DOCSIS data. Channel Bonding allows two types of Bonding Group (BG) interfaces. These are Secondary BG interface and non-Secondary BG interface. The Secondary BG interfaces will carry the multicast traffic, whereas, the non-Secondary BG interface will carry the non-multicast traffic. This MIB also allows for configuration of the RF channels on the WCMTS, as well as the association between the RF and narrowband downstream channels with the BG channel. Fiber Node is an optical node which terminates the fiber based downstream signal as an electrical signal onto a coaxial RF cable. DEPI: Downstream external physical interface. TSID: MPEG2 Transport Stream ID. SFP: Small Form-Factor Pluggable.

This table contains attributes of the physical RF channels. MPEG-TS packets are sent across RF channels within a wideband channel. These physical RF channels might be present on a different system but the WCMTS entity requires the knowledge of that system for its operation.

An entry provides a list of attributes for a single downstream RF channel per WCMTS entity. An entry in this table exists for each configured RF channel on the WCMTS entity that provides the wideband DOCSIS functionality. The index, entPhysicalIndex, used here is the physical index of the wideband controller card. Since RF channels are considered part of the Wideband controller card, hence entPhysicalIndex is used for associating RF channels.
