Casa Distributed Access Architecture overview

The Casa Distributed Access DA1000 and DA2000 outdoor Remote PHY Device (RPD) enclosures provide a cost-effective way for cable operators to provide DOCSIS 3.0 cable services to customers in remote areas over short, extended and long-reach fiber optic cable.

Using the new CCAP 8x10G Service Card 8x10G (CSC) at the C100G or C40G platform positioned at a selected cable head-end location, each RPD connects to a single fiber optic SFP at the CSC. The CSC combines the upstream (UPS) and QAM downstream core functions, as well as assumes mastership of the timing role and back-end processing between the CCAP and the RPD, with the RPD assuming the timing slave role. Each RPD houses the PHY components that are normally used in the CMTS/CCAP hardware modules.

The CSC 8x10G provides eight xGigE port interfaces with up to two downstream and up to four upstream interfaces per connection to the DA2000 RPD (with half that capacity at the DA1000). In non-redundant configurations, the CSC 8x10G can occupy up to twelve slots on the C100G platform (using slots 0–5 and 8–13 for up to 96 ports), or up to four slots on the C40G (using slots 0–1 and 4–5 for up to 32 ports).

Casa Version 8.2 software and the Casa CLI allows operators to configure, manage, and monitor the RPD from any location in the network (Figure 1). Matching, but uniquely named software images, are required between the CCAP and the connected RPD nodes.

For complete hardware and configuration information on the DA1000/2000 RPD hardware and the CSC, as well as the presently supported features, see the following Casa documents:

• Casa Systems – Distributed Access Architecture Release 8.2 Features Guide


Note: Presently, QAM and UPS modules which are typically used with the C100G and C40G platforms in traditional CMTS and CCAP cable networks are not presently supported in Release 8.0. Full mixed integration of QAM, UPS and CSC modules in a single chassis but will be supported in a later release.

DA1000 and DA2000 Remote PHY Device enclosures

Casa RPD enclosures are designed for above-ground guy wire installation, or installation on the ground in a telecommunications equipment cabinet in areas that are serviced with underground utilities. Each enclosure consists of a weather-tight metal cases with a pivoting top cover with a rubber seal and an EMI gasket. Bolts are used to secure the top cover to the enclosure to protect the enclosure from weather and the elements. The bolts can be loosened and removed anytime to allow personnel to open the lid for system maintenance or adjustment, as well as attach a local console should the system be unavailable over the CSC 8x10G network ports.

There are two types of RPD enclosures, each based on traffic capacity requirements:

• DA2000 — Large enclosure containing two remote PHY modules (Figure 2 and Figure 3)

• DA1000 — Small enclosure containing one remote PHY module (Figure 4 and Figure 5)

Figure 2. Casa DA2000 Remote PHY Device (large enclosure)



Figure 3. Casa DA2000 inside view



Figure 4. Casa DA1000 Remote PHY Device (small enclosure)

Figure 5. Casa DA1000 inside view



RPD components include:

• Sealed metal weather-tight enclosure with a hinged body unit and lid for aerial strand or pedestal installation.

• Primary and secondary radio frequency (RF) module with a single or additional redundant power supply.

• Master and optional second master RPD module. The module is responsible for providing a DOCSIS physical layer interface in both the upstream and downstream directions.

• Optional Redundant Forward Optical Receiver modules for analog overlay.

For complete information, on the DA1000 and DA2000 RPD enclosures, see the Casa Systems – DA1000/2000 System Hardware and Configuration Guide.

CCAP Service Card (CSC 8x10G)

The CCAP Service Card (CSC 8x10G) shown in Figure 6 is a single multi-core processor which provides high-speed interfaces for CMTS/CCAP connectivity to up to eight RPD enclosures. Eight xGigE port interfaces support long, extended, and short range fiber optic small form-factor pluggable (SFP) modules. LEDs on the front CSC provide Ethernet transmit (Tx) and receive (Rx) status on a per-port basis.

The CSC provides eight DOCSIS MAC ports to support the following functionality:

• Downstream DOCSIS encryption (AES and DES)

• Downstream video encryption (PKE and PME; future DVB support)

• Upstream DOCSIS decryption (AES and DES)

• Generation of RXAUI flow control packets.

• DOCSIS and IEEE 1588 timing support.

Two DOCSIS MAC ports provide bandwidth to support 256 downstream channels and 128 upstream channels per port interface, translating to approximately 10 Gb/s of downstream throughput, and 3.8 Gb/s of upstream throughput.



Figure 6. Casa CCAP Service Card (CSC 8x10G)

For complete information on the CSC 8x10G, see the Casa Systems – DA1000/2000 System Hardware and Configuration Guide.

CCAP Out-of-Band (OOB) I/O module

The CSC Out-of-Band (OOB) I/O module (Figure 7) provides Narrowband Digital Forward (NDF) and Narrowband Digital Return (NDR) physical signaling capabilities to support two-way legacy set-top box (STB) equipment operating with the Remote PHY node. The OOB I/O module is equipped with four RF ports (labeled NDF0, NDF1, NDR0, and NDR1) that connect to external OOB signaling equipment (per the SCTE 55-1 or SCTE 55-2 standard) in the cable headend, where analog signals are digitized in the upstream (NDR) and the downstream (NDR) channel spectrum before being converted back to analog RF signals at the Remote PHY node.

At least one NDF (downstream) port connection and one NDR (upstream) port connection as a set (such as NDF0 and NDR0) are required from the OOB I/O module to the OOB signaling device. Ports NDF1 and NDR1 can be connected to a second OOB signaling device using the SCTE55-1 or SCTE55-2 standard.

CCAP and RPD system management

The Casa C40G, C100G CMTS/CCAP platforms and the DA1000/2000 RPD nodes are configured and managed using the Casa CLI over a local or Telnet connection. Additionally, the casa-remote-phy-mib file has been implemented in the Release 8.0 MIB archive for SNMP monitoring and trap capabilities. Refer to the Casa Systems – Distributed Access Architecture Release Notes for SNMP archive file available from Casa Systems.

DA1000 and DA2000 RPD nodes include a local console port for a direct management connection at the enclosure. The port is intended for diagnostic and troubleshooting purposes under the guidance of Casa Technical Support personnel.

Integration of QAM, UPS, and CSC modules

Full integration of QAM, UPS, and CSC modules in a single chassis is now supported. This means that the CSC module can be now be added to any existing C40G or C100G chassis with co-existing QAM and UPS modules.

OFDM channel support at the Remote PHY node

Release 8.2 supports one OFDM downstream channel to the Remote PHY device (RPD). The OFDM channel is configured at the CCAP under the interface docsis-mac configuration using the downstream <identifier> interface ofdm n:slot/port/channel command.

The <n>: node prefix allows for up to 96 RPD IDs in the range 1 to 96. The slot/port/channel identifier specifies the CSC module slot and port number on the C40G or C100G chassis.

The following example configures the OFDM interface to RPD 80.

Example

CASA(conf-if-mac 1)# downstream 1 interface ofdm ?[N:]X/Y/Z N - RPHY Node Id X - slot, Y - port,

Z - downstream channelCASA(conf-if-mac 1)# downstream 1 interface ofdm 80:0/0/0

Note: Presently, CSC module redundancy is NOT supported in C40G or C100G redundancy slots. Casa recommends that you continue to use the redundancy slots for the existing QAM or UPS modules. In non-redundant sys-tems, CSC modules occupying the redundancy slots will boot to active mod-ules at system startup.



New OOB NDR and NDF commands

The interface oob-ndf and the interface oob ndr commands have been introduced in the Casa CLI to configure the Narrowband Digital Forward (NDF) and Narrowband Digital Reverse (NDR) traffic parameters. The CSC module supports two NDF interfaces and two NDR interfaces.

Perform the following steps in the Casa configuration mode:

1. Enter interface oob-ndf configuration mode to set up Narrowband Digital Forward (NDF) traffic from the OOB signal controller to the STB equipment at the customer end using the NDF slot and channel number.

Example

CASA(config)# interface oob-ndf 1/0CASA(conf-oob-ndf 1/0)#

2. Set the transport MAC address for OOB packets. Presently, the transport-address is fixed and cannot be changed.

Example

CASA(conf-oob-ndf 1/0)# transport-address 386b.bbd7.d687

3. Set the center frequency for OOB captures in the range 70000000-130000000 Hz (the low pass filter begins rolling off above 130 MHz). If both channels are used for NDF, the center frequencies must be 2 MHz apart. This is a requirement for NDF traffic only.

Channel 0 always gets the lower center frequency and the channel 1 frequency automatically set 2 MHz higher. If channel 1 is set first, channel 0 is automatically set 2 MHz lower.

Example

CASA(conf-oob-ndf 1/0)# frequency 90000000

4. Set the channel-width for the OOB captures, either 2.56 MHz or 25.6 MHz. Presently, the channel-width is fixed at 2.56 MHz.



Example

CASA(conf-oob-ndf 1/0)# channel-width 2.56

5. Set the input power for the OOB modulator in the range 250-560 in units of 1/10 dBmV.

Example

CASA(conf-oob-ndf 1/0)# input-power 250

6. Set the output power offset for the OOB demodulator in the range -6-6 dB. Presently, the output power cannot be changed.

Example

CASA(conf-oob-ndf 1/0)# output-power-offset 0

7. Execute the show this command to see the NDF configuration results.

Example

CASA(conf-oob-ndf 1/0)# show thistransport-address 386b.bbd7.d687frequency 90000000channel-width 2.56input-power 250output-power-offset 0

8. Enter the interface oob-ndr configuration mode to set up Narrowband Digital Reverse (NDR) traffic from the STB equipment at the customer end to the OOB signal controller using the specified NDR slot and channel number.

Example

CASA(config)# interface oob-ndr 1/1CASA(conf-oob-ndr 1/1)#

9. Set the center frequency for OOB captures in the range 5 MHz to 26.5 MHz

Example

CASA(conf-oob-ndr 1/1)# frequency 26500000

10. Set the channel-width for the OOB captures, 1.28 MHz, 2.56 MHz, or 5.12 MHz.



Example

CASA(conf-oob-ndr 1/1)# channel-width 2.56

11. Set the input-power for the OOB modulator in the range 250-560 in 1/10 dBmV. Presently, the input-power cannot be changed.

Example

CASA(conf-oob-ndr 1/1)# input-power 250

12. Set the output-power-offset for the OOB demodulator in the range -16 dBmV to 15 dBmV in 1 dBmV units

Example

CASA(conf-oob-ndr 1/1)# output-power-offset 0

13. Execute the show this command to display the NDR configuration results.

Example

CASA(conf-oob-ndr 1/1)# show thisfrequency 26500000channel-width 2.56input-power 250output-power-offset 0

14. Enter remote-phy-node configuration mode to set up OOB with the Remote PHY device ID range of 1 to 96.

Example

CASA(conf-oob-ndr 1/1)# endCASA(config)# remote-phy-node 1CASA(config-rphy-node 1)#

15. Enable or disable NDF at the node using the OOB slot/port number.

Example

CASA(config-rphy-node 1)# oob-ndf 1/0CASA(config-rphy-node 1)# no oob-ndf 1/0



16. Optional. With NDF enabled, optionally set the output-power (-12-3 dBmV) for the NDF port and channel (1 or 2). Presently, the output-power cannot be changed at the Remote PHY device.

Example

CASA(config-rphy-node 1)# oob-ndf 1/1 output-power 0 ndf-channel 0

17. Enable or disable NDR at the node using the OOB slot/port number.

Example

CASA(config-rphy-node 1)# oob-ndr 1/1CASA(config-rphy-node 1)# no oob-ndr 1/1

18. Optional. With NDR enabled, optionally set the input-power (-12 to 3 dBmV) for the NDR port and channel (1 or 2). Presently, the input-power cannot be changed at the Remote PHY device.

Example

CASA(config-rphy-node 1)# oob-ndr 1/1 input-power 0 ndr-channel 119. Execute the show this command to display the Remote PHY node results.

Example

CASA(conf-oob-ndr 1/1)# show thisremote-phy-node 1mac address 0017.100f.6fc0ip-bundle 1node-type master-onlynode ip address 12.197.249.249xgige 11/1oob-ndf 1/0oob-ndf 1/0 output-power 0 ndf-channel 0oob-ndr 1/1oob-ndr 1/1 input-power 0 ndr-channel 1operStatus onlinenumber of slots: 1number of qam ports: 1number of qam channels: 64number of ups ports: 2number of ups phychans: 8number of ups logchans: 2no shutdown



Video on Demand (VOD) support at the Remote PHY node

The follow video features are supported in Release 8,2:

• Up to 32 DOCSIS channels and up to 16 VOD sessions per CSC port per Remote PHY node.

• PME and PKE video encryption

The following video features are NOT presently supported at the Remote PHY node.

• DVB Simulcrypt encryption

• Switched Digital Video (SDV)

New video commands

The video virtual-qam command has been introduced to support provisioning of video sessions to the Remote PHY node. The virtual QAM is a QAM instance running on the CCAP to support one or more video interfaces. There is no fixed mapping between the virtual QAM and CSC card; one CSC can serve multiple virtual QAMs, and a virtual QAM can be served by multiple CSCs.

The video virtual-qam command accepts a QAM identifier in the range 14 to 29. (Identifiers in the range 0 to 13 are reserved for CCAP QAM modules.)

Each video virtual-qam instance supports up 24 ports and up to 36 channels.

Example

CMTS(config)# video virtual-qam 14CMTS(conf-virt-qam 14)# ports 5 channels 12

CMTS(config)# video qam-domain 4CMTS(conf-qam-domain 4)# virtual-qam 14CMTS(conf-qam-domain 4)# qam-group 1<X/Y/Z> X - slot, Y - port, Z - channelrphy-channel remote-phy channelshared-channel shared channel

CMTS(conf-qam-domain 4)# qam-group 1 rphy-channel ?<N:X/Y/Z> N - RPHY node id, X - slot, Y - port, Z - channel
