Configuring Channels and Clear-Channel and Channelized Ports

Overview

1 Overview

This document describe how to configure and administer the data channelssupported by clear-channel and channelized ports. The following types of trafficcards support data channels: DS-3, E1, E3, OC-12, and STM-1.

The commands described in this document are common to the following porttypes, except where noted:

• Clear-channel ports—DS-3, E1, E3 traffic cards

• Channelized ports—DS-3, E1, channelized OC-12, channelized STM-1traffic cards

Restrictions:

• The SmartEdge 100 router does not support the clear-channel andchannelized ports described in this document.

• The XCRP4 Controller card does not support channelized OC-12c/STM-4ctraffic cards.

• The XCRP4 Controller card supports channelized STM-1c traffic cards, butonly when installed in the SmartEdge 800 chassis.

• The SmartEdge 1200 router does not support first-generation SONET/SDHtraffic cards.

The following terms are used in this document:

• The term port refers to the physical entity on a traffic card.

• The term channel refers to a time-division multiplexed segment of thebandwidth of an E1, E3, DS1, or DS3 port. This document uses the termsubchannel to refer to a time-division multiplexed segment of a channel.Each channel is designated by its port number and channel number.Each subchannel is designated by its port number, channel number, andsubchannel number.

• The terms clear-channel and unchannelized are both used to refer to an E1,E3, DS1, or DS3 port that does not support channels. Channelized portsgenerally support both unchannelized operation and channelized operation.

1.1 Traffic Card Support for Channels

Table 1 lists the SmartEdge router traffic cards that support E1, E3, DS1, andDS3 ports.

1.2 Bandwidth Provided by Channelized Ports

The bandwidth provided by channelized ports and channels is as follows:

• Each port on a channelized OC-12 to DS-3 or OC-12 to DS-3/DS-1 trafficcard provides the bandwidth for up to 12 DS-3 channels.

• Each port on a channelized STM-1 traffic card provides the bandwidth forup to 63 E1 channels; E1 channels can be channelized or clear-channel.

• A channelized DS-3 port or channel provides the bandwidth for 28 DS-1channels, each of which has the bandwidth for 24 DS-0 channels.

• A channelized E1 port or channel supports up to 31 DS-0 channels foruser traffic in a DS-0 channel group.

Overview

1.3 Additional Terminology

Note: The term controller card refers to any version of the Cross-ConnectRoute Processor (XCRP) Controller card (XCRP, XCRP3, XCRP4),including the controller carrier card, unless otherwise noted.

The term controller carrier card refers to the controller functions on thecircuit board within the SmartEdge 100 chassis; these functions arecompatible with the XCRP3 Controller card. The term I/O carrier cardrefers to the traffic card functions on the circuit board; these functionsare compatible with the similar functions that are implemented on allSmartEdge 400 and SmartEdge 800 traffic cards.

The term chassis refers to any SmartEdge chassis; the term SmartEdge800 refers to any version of the SmartEdge 800 chassis; the termSmartEdge 800s refers only to the SmartEdge 800s chassis.
