Cisco Remote-PHY Solution

Cisco Remote-PHY (a.k.a REMOTE-PHY) enables cable operators to deploy DOCSIS-based networks over digital fiber while obtaining all of the benefits of using standards-based equipments. These benefits include the utilization of scalable, cheap and easy to operate digital fiber, standardized and proven QoS for various services, lower cost, and wide availability of both cable modem and set-top box systems. Furthermore, with deep fiber, the optical noise contribution to SNR is eliminated. As a result, the remote QAM modulator runs at higher orders of modulation as compared to a centralized QAM modulator.

Cisco Coaxial Media Converter

Cisco Coaxial Media Converter (CMC) acts as the edge QAM in the Cisco Remote-PHY architecture. It is located between the Cisco CMTS and the cable modem, and controlled by the Cisco CMTS router. Cisco CMC has network interfaces on one side connecting to the fiber (digital and linear) portion of the Hybrid Fiber Coaxial (HFC) plant, and RF interfaces on the other side connecting to the coaxial portion of the HFC plant. Cisco CMC terminates the Ethernet Passive Optical Network EPON protocol with an embedded Optical Network Unit (ONU) and originates the DOCSIS protocol using DOCSIS MAC and PHY layer technology found in Cisco CMTS.

Cisco CMC uses the Linux operating system. Most of the Cisco CMC configurations are performed on the Cisco CMTS router.

New Software Features in Cisco CMC OS 1.0

This section describes new software features in Cisco CMC OS 1.0.

DHCP Client

DHCP is a dynamic IP address assignment protocol. The Cisco CMC OS 1.0 gets IP address from remote DHCP server and new firmware data paths using this feature.

GCP Client

GCP (generic control protocol) is a control protocol between the Cisco CMTS and the Cisco CMC. The Cisco CMC OS 1.0 receives GCP packets for commands and configurations from the Cisco CMTS and properly acknowledges itself as a GCP client.

Telnet and SSH

The Cisco CMTS uses Telnet and secure Shell (SSH) to access the Cisco CMC remotely.

TFTP and FTP

Cisco CMC OS 1.0 uses TFTP and FTP to download files for upgrading the CMC OS.

Modified Software Features in Cisco CMC OS 1.1

There are no modified software features in Cisco CMC OS 1.1.

Modified Software Features in Cisco CMC OS 1.0

There are no modified software features in Cisco CMC OS 1.0.

Features Integrated in Cisco CMC OS 1.1

There are no integrated features in Cisco CMC OS 1.1.

Features Integrated in Cisco CMC OS 1.0

There are no integrated features in Cisco CMC OS 1.0.

MIBs

To locate and download MIBs for selected platforms, Cisco CMC OS releases, and feature sets, use Cisco MIB Locator found at the following URL:

http:/​/​tools.cisco.com/​ITDIT/​MIBS/​servlet/​index

If Cisco MIB Locator does not support the MIB information that you need, you can also obtain a list of supported MIBs and download MIBs from the Cisco MIBs page at the following URL:

http:/​/​www.cisco.com/​public/​sw-center/​netmgmt/​cmtk/​mibs.shtml

To access Cisco MIB Locator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check verifies that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password is e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

http:/​/​tools.cisco.com/​RPF/​register/​register.do

New and Changed MIB Information in Cisco CMC OS 1.1

There are no new or modified MIBs in Cisco CMC OS 1.1.

New and Changed MIB Information in Cisco CMC OS 1.0

The following new MIBs are introduced for Cisco CMC OS 1.0:

  • CISCO-CDOC-CHGRP-MIB
  • CISCO-CMC-MGR-MIB

Limitations and Restrictions

Cisco CMC OS 1.0

While upgrading the software images for the Cisco Remote-PHY solution, upgrade the Cisco CMC first, and then upgrade the Cisco CMTS.


Note
If the Cisco CMTS is upgraded before the Cisco CMC, the Cisco CMC may not come online.
