This appendix includes miscellaneous specficiations that you can use when provisioning subscribers on a Cisco 6100 Series system.

This appendix includes the following sections:

Cisco 6100/6130 Module Intermixing

The Cisco 6100 and Cisco 6130 chassis support module intermixing. However, the quad-port STU-C modules must be segregated in either the left or right half of the chassis (left half is slots 1 to 8 and 21 to 28; right half is slots 13 to 20 and 31 to 38 ). The STU-C modules may not be intermixed with other module types within the same chassis half. Table 1 details the module intermixing configurations in a Cisco 6100 or Cisco 6130 chassis.

Reed-Solomon Coding Module Applications

You can configure Reed-Solomon (RS) error coding per subscriber.

Note You can disable Reed-Solomon for 136 kilobaud rate in the downstream direction only.

Consider the following guidelines in relation to using Reed-Solomon coding:

For Dual-port CAP ATU-C and quad-port flexi ATU-C modules, Reed-Solomon is always disabled for upstream.
- You can select Reed-Solomon by choosing Short or Long interleaved destination depth. Choose Short for time-sensitive traffic; choose Long for time-insensitive traffic.
- You can only disable Reed-Solomon in 136 kilobaud downstream. For all other baud rates, the Reed-Solomon is always on in downstream, with Long Interleaved as the default.
For Dual-port DMT-2 ATU-C and quad-port flexi ATU-C modules:
- Dual-port DMT-2 ATU-C and quad-port flexi ATU-C are available in both upstream and downstream directions.
- Reed-Solomon coding in dual-port DMT-2 ATU-C can be achieved in Interleaved latency mode by setting the interleaved delay or the redundancy byte.
- Reed-Solomon coding in dual-port DMT-2 ATU-C can be achieved in Fast latency mode by setting the redundancy bytes only.
G.lite: You can set G.lite Reed-Solomon coding by interleaved delay because G.lite does not operate on Fast latency mode.

Performance Counter Definitions

Table A-2 describes ViewRunner performance counters for a DMT-2 module.

Table A-2: Performance Counters

Performance Monitor Name Description

HecViolI

The near-end HEC_violation_count-I performance parameter is a count of the number of occurrences of a near-end hec-I anomaly.

HecViolF

The near-end HEC_violation_count-I performance parameter is a count of the number of occurrences of a near-end hec-F anomaly.

HecCellI

The near-end HEC_violation_count-I performance parameter is a count of the number of occurrences of a near-end hec-I anomaly.

HecCellI

Total_cell_count-I performance parameter is a count of the total number of cells passed through the cell delineation process operating on the interleaved data while in the SYNC state.

HecCellF

Total_cell_count-F performance parameter is a count of the total number of cells passed though the cell delineation process operating on the fast data while in the SYNC state.

FarAttenuation

The far-end attenuation is the attenuation measured at the far-end. It can be read from the eoc ATN register using the eoc command set. The eoc ATN register is coded as an unsigned integer, ranging from 0 to 127, corresponding to a 0 to 63.5 dB attenuation (0.5 dB steps).

FarSNRMargin

The far-end SNR margin is the SNR margin measured at the far-end.

NearSNRMargin

The SNR margin represents the amount of increased received noise (in dB) relative to the noise power that the system is designed to tolerate and still meet the target bit error rate (BER) of 10 ⁷, accounting for all coding (for example, RS FEC) gains included in the design. The SNR margin ranges from -64.0 dB to +63.5 dB with 0.5 dB steps

NearAttenuation

The attenuation is the difference in dB between the power received at the near-end and that transmitted from the far-end. Received signal power in dBm is the sum of all data-carrying (that is, b i > 0) DMT-2 sub-carrier powers averaged over a 1-second period. Transmitted signal power is 3.65 + 10log(S gi 2) dBm, summed over the data-carrying subcarriers. The attenuation ranges from 0 to 63.5 dB with 0.5 dB steps.
