Configuring CESM Cards

Configuring CESM Cards

The CESM modules facilitate emulation of Constant Bit Rate (CBR) over an ATM Network shelf control and shared-memory switching functions. WAN CiscoView supports the CESM T1/E1 and 8E1 cards.

Selecting the Card and Displaying Card Parameters

Select the CESM card to display CESM card configuration dialogs by doing one of the following:

The CESM Card Category menu contains several dialogs:

Note This is not a configurable dialog. The CLI commands related to this dialog are dspfeature, chanfst, and clrsmcnf.

Lines

Use this dialog to configure dsx1 lines on a CESM card. (See Figure 5-2.)


Figure 5-2: Lines Dialog (dsx1)


Table 5-3 describes the Lines dialog parameters.


Table 5-3: CESM Lines Dialog Parameters (dsx1)
Parameter Description

Line Number

Line number.

Line Connector Type

Line connector type. Can be:

  • db15

  • bnc

  • rj48

Line Enable

Used to disable, enable or modify a line.

Line Type

Indicates the type of line. Choose dsx1E1clearchannel from the pop-up menu. It is the only option supported on a CESM card.

Line Coding

Type of zero code suppression used on the line, which in turn affects a number of its characteristics. Choose one from the pop-up menu:

  • dsx1JBZS: Jammed Bit Zero Suppression, in which the AT&T specification of at least one pulse every 8 bit periods is literally implemented by forcing a pulse in bit 8 of each channel. Thus, only seven bits per channel (1.344 Mbps) is available for data.

  • dsx1B8ZS: Refers to the use of a specified pattern of normal bits and bipolar violations, which are used to replace a sequence of eight zero bits.

  • dsx1HDB3: Used by E1 links, with or without CRC.

  • dsx1AMI: Refers to a mode wherein no zero code suppression is present and the line encoding does not solve the problem directly. In this application, the higher layer must provide data that meets or exceeds the pulse density requirements, such as inverting HDLC data.

  • unused

The default value for T1 is dsx1JBZS. The default value for E1 is dsx1HDB3.

Line Length

The line length. Choose one from the pop-up menu:

  • lineLength0to110Feet

  • lineLength110to220Feet

  • lineLength220to330Feet

  • lineLength330to440Feet

  • lineLength440to550Feet

  • lineLength550to660Feet

  • lineLength660FeetPlus

  • lineLength-75-0hm

  • lineLength-120-0hm

  • lineLength0to131Feet

  • lineLength131to262Feet

  • lineLength262to393Feet

  • lineLength393to524Feet

  • lineLength524to655Feet

  • lineLength655FeetPlus

The default value for T1 is 1. For an E1, the default is 9 if the connector type is DB15. If the connector type is BNC, the default 8.

Line Xmt Clock Source

Transmit clock source. Choose loopTiming from the pop-up menu. The other options are not supported on a CESM card.

Line Loopback Configuration

Line loopback configuration of the DS1 interface. Agents supporting read/write access should return badValue in response to a requested loopback state that the interface does not support. Choose one from the pop-up menu:

  • dsx1LocalLoop: Local data is looped back.

  • dsx1NoLoop: Not in the loopback state. A device that is not capable of performing a loopback on the interface shall always return this as its value.

  • dsx1RemoteLoop: Received signal at this interface is looped through the device. Typically the received signal is looped back for retransmission after it has passed through the device's framing function.

Use Line Loopback Configuration to troubleshoot the network.

Type of Code Sent Across DS1

Indicates the type of code sent across the DS1 interface by the device. Choose one from the pop-up menu:

  • dsx1SendNoCode: Sending looped or normal data.

  • dsx1SendLineCode: Sending a request for a line loopback.

  • dsx1SendPayLoadCode: Sending a request for a payload loopback.

  • dsx1SendResetCode: Sending a loopback termination request.

Used DS0 Time Slots

Bitmap of DS0s for this line.

Enable Detection of Line Lpbk Codes

Indicates whether or not detection of line loopback codes is enabled. Choose codeDetectDisabled or codeDetectEnabled from the pop-up menu.

Step 1 Select the table column entry that you want to modify.

Step 2 View the possible value, if available, by displaying the pop-up menu next to the entry.

Step 3 Select or enter the appropriate value in the table column.

Step 4 Click Modify.

To make sure your changes went through, close and reopen the Lines table.
