Purpose

Step 1

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

network-clock-participate [slot slot-number | wic wic-slot]

Example:

Router(config)# network-clock-participate wic 0

TDM group configuration only. Allows the ports on a specified network module or interface card to use the network clock for timing.

Step 4

controller {t1 | e1} slot/subslot/port

Example:

Router(config)# controller t1 1/0

Enters controller configuration mode. For interface numbering conventions on the Cisco 2800 and 3800 series routers, see the "Interface Numbering on Cisco 2800 and Cisco 3800 Series Routers" section.

Step 5

framing {sf | esf}

or

framing {crc4 | no-crc4}

Example:

Router(config-controller)# framing esf

In T1 configurations, specifies super frame (sf) or extended super frame (esf) as the frame type for data lines. Default is esf.

In E1 configurations, specifies cyclic. redundancy check 4 (crc4) or no-crc4 as the frame type for data lines. Default is crc4.

Step 6

linecode {ami | b8zs}

or

linecode {ami | hdb3}

Example:

Router(config-controller)# linecode b8zs

In T1 configurations, specifies alternate mark inversion (AMI) or b8zs as the linecode. Default is b8zs.

In E1 configurations, specifies AMI or high-density bipolar 3 (hdb3) as the linecode. Default is hdb3.

Note When using linecode AMI, the user is advised to select 56 kbps as the speed or make sure that the channel groups created do not contain all the timeslots. See Step 12. This is to avoid exceeding the "15 zeroes" threshhold specified by standards.

Step 7

fdl {att | ansi | both}

Example:

Router(config-controller)# fdl both

T1 only. Sets the facility data link (fdl) exchange standard for T1 interfaces using esf framing. Can select the ATT standard (ATT TR54016), the ANSI standard (ANSI T1.403), or both standards. Default is ansi. To disable fdl, enter the command no fdl.

Step 8

clock source {line [independent] | internal}

Example:

Router(config-controller)# clock source line

line specifies that the clocking on this controller is derived from an external source, generally the telephone central office. line independent configures the port to be independent in the TDM docmain, which is when network-clock-participate is configured on the card.

internal specifies that the clock is generated by internal controller circuitry.

Default is line.

Step 9

line-termination {75-ohm | 120-ohm}

Example:

Router(config-controller)# line-termination 75-ohm

E1 only. Sets the line termination on an E1 controller.

•75-ohm specifies the 75 ohm unbalanced termination.

•120-ohm specifies the 120 ohm balanced termination.

Default is 120-ohm.

Note On the 4-port HWIC and 8-port network module, line impedance will be set to the same value for each port in a two-port slice automatically. That is, on the 4-port HWIC, ports 0 and 1 will be set to the same value, and ports 2 and 3 will be set to the same value. On the 8-port network module, ports 0 and 1 will be set to the same value, as will ports 2 and 3, ports 4 and 5, and ports 6 and 7. In these cases, a message will be displayed. The example here shows the message displayed when the line termination on port 0 is changed:
Router(config)# controller e1 0/1/0 Router(config-controller)#line-termination 75-ohm Changing the line termination for ports 0 and 1 to 75

Step 10

loopback {diagnostic | local {payload | line} | remote {iboc | esf {payload | line}}}

Example:

Router(config-controller)# loopback remote esf line

Sets the loopback method for testing the interface. Options are:

•diagnostic loops transmit signal back to receive

•local puts the interface into local loopback mode at the payload or line level

•remote puts the interface into remote loopback mode through an inband bit oriented code (iboc) or, for T1 only, remote esf, which uses fdl codes to set payload or line levels.
Step 11
cablelength long db-loss-value
or

cablelength short length

Example:

Router(config-controller)# cablelength short 133
T1 only. cablelength long attenuates the pulse from the transmitter using pulse equalization and line build-out. This command applies to cables longer than 660 feet. Loss values are:

•0db

•-7.5db

•-15db

•-22.5db

Default attenuation is 0db.

cablelength short sets transmission attenuation for cable lengths of 660 feet or less. Cable lengths can be specified as follows:

•110 for cable lengths from 0 to 110 feet

•220 for cable lengths from 110 to 220 feet

•330 for cable lengths from 220 to 330 feet

•440 for cable lengths from 330 to 440 feet

•550 for cable lengths from 440 to 550 feet

•660 for cable lengths from 550 to 660 feet

There is no default cable length.
Step 12
channel group channel-group-number {timeslots range [speed kbps] | unframed}
or

pri-group timeslots timeslot-range
or

tdm-group tdm-group-no timeslots timeslot-range

Example:

Router(config-controller)# channel group 1 timeslots 1-4
Note This step does not apply to the clear channel 4-port T1/E1 HWIC.

Configures the serial WAN on a T1 or E1 interface by specifying channels and their timeslots.

For T1, values are as follows:

•channel-group-number is from 0 to 23

•timeslots range is from 1 to 24

•Default value of speed in T1 is 64 kbps. Configuration of speed is optional.

For E1, values are as follows:

•channel-group-number is from 0 to 30

•timeslots range is from 1 to 31

•Default value of speed in E1 is 64 kbps. Configuration of speed is optional.

•unframed (E1 only) specifies that all 32 timeslots are to be used for data, and that none are to be used for framing signals.

or

Configures specified timeslots on T1 or E1 interfaces for PRI for transporting ISDN data.

or

Configures specified timeslots on T1 or E1 interfaces to create clear chanel groups for time division multiplexing.

For the tdm-group configuration to work, it is necessary to configure network-clock-participate for the interface in global configuration mode.
Step 13

national reserve N sa4 sa5 sa6 sa7 sa8

Example:

Router(config-controller)# national reserve 0 1 1 1 1 0

E1 only. Sets the 6 required national bits in E1 in the G.751 frame. Default is 1 1 1 1 1 1.

Step 14

crc-threshold value

Example:

Router(config-controller)# crc-threshold 500

T1 only. Defines a severely errored second by specifying the number of crc errors that must occur in one second to reach the severely errored state. Default is 320.

Step 15

yellow {generation | detection}

Example:

Router(config-controller)# no yellow detection

Enables generation and detection of yellow alarms. Default condition is that generation and detection of yellow alarms are enabled.

Use the no form of the command to disable yellow alarm detection.
Step 16
bert pattern pattern interval time
Example:

Router(config-controller)# bert 2^11 interval 1440
Optional. Activates the Bit Error Rate Tester (bert) with the chosen test pattern for a specified duration.

Configure bert patterns on T1/E1 HWICs or network module as follows:

•When the linecode is AMI, use patterns 2^11, 2^15, or 2^20-QRSS.

•When the linecode is b8zs or hdb3, use patterns 2^11, 2^15, 2^20-QRSS, or 2^20-O.153.

Note If any other bert pattern is chosen, an error message will appear that lists the supported patterns for the configured linecode. A complete listing of bert patterns is in the Cisco IOS Master Commands List, Release 12.4.

interval time is from 1 to 14,400 minutes.

Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	card type {t1 \| e1} slot subslot Example: Router(config)# card type t1 0 2	Specifies T1 or E1 connectivity. slot refers to the network module slot on the 2800 series and 3800 series platform. subslot refers to the HWIC slot on the platform. See the "Interface Numbering on Cisco 2800 and Cisco 3800 Series Routers" section.

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	no card type {t1 \| e1} slot subslot Example: Router(config)# no card type t1 0 2	Optional. Removes the previously configured card type for the HWIC or network module.
Step 4	card type {t1 \| e1} slot subslot Example: Router(config)# card type e1 0 2	Specifies T1 or E1 connectivity for the HWIC or network module.
Step 5	write Example: Router(config)# write	Rebuilds the router configuration.
Step 6	reload Example: Router(config)# reload	Reloads router so that changes can take affect. After this command executes, the router will go to ROM monitor (rommon) mode.
Step 7	boot Example: Router(rommon)# boot	Boots the router for the configuration with the newly selected card type.

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	network-clock-participate [slot slot-number \| wic wic-slot] Example: Router(config)# network-clock-participate wic 0	TDM group configuration only. Allows the ports on a specified network module or interface card to use the network clock for timing.
Step 4	controller {t1 \| e1} slot/subslot/port Example: Router(config)# controller t1 1/0	Enters controller configuration mode. For interface numbering conventions on the Cisco 2800 and 3800 series routers, see the "Interface Numbering on Cisco 2800 and Cisco 3800 Series Routers" section.
Step 5	framing {sf \| esf} or framing {crc4 \| no-crc4} Example: Router(config-controller)# framing esf	In T1 configurations, specifies super frame (sf) or extended super frame (esf) as the frame type for data lines. Default is esf. In E1 configurations, specifies cyclic. redundancy check 4 (crc4) or no-crc4 as the frame type for data lines. Default is crc4.
Step 6	linecode {ami \| b8zs} or linecode {ami \| hdb3} Example: Router(config-controller)# linecode b8zs	In T1 configurations, specifies alternate mark inversion (AMI) or b8zs as the linecode. Default is b8zs. In E1 configurations, specifies AMI or high-density bipolar 3 (hdb3) as the linecode. Default is hdb3. Note When using linecode AMI, the user is advised to select 56 kbps as the speed or make sure that the channel groups created do not contain all the timeslots. See Step 12. This is to avoid exceeding the "15 zeroes" threshhold specified by standards.
Step 7	fdl {att \| ansi \| both} Example: Router(config-controller)# fdl both	T1 only. Sets the facility data link (fdl) exchange standard for T1 interfaces using esf framing. Can select the ATT standard (ATT TR54016), the ANSI standard (ANSI T1.403), or both standards. Default is ansi. To disable fdl, enter the command no fdl.
Step 8	clock source {line [independent] \| internal} Example: Router(config-controller)# clock source line	line specifies that the clocking on this controller is derived from an external source, generally the telephone central office. line independent configures the port to be independent in the TDM docmain, which is when network-clock-participate is configured on the card. internal specifies that the clock is generated by internal controller circuitry. Default is line.
Step 9	line-termination {75-ohm \| 120-ohm} Example: Router(config-controller)# line-termination 75-ohm	E1 only. Sets the line termination on an E1 controller. •75-ohm specifies the 75 ohm unbalanced termination. •120-ohm specifies the 120 ohm balanced termination. Default is 120-ohm. Note On the 4-port HWIC and 8-port network module, line impedance will be set to the same value for each port in a two-port slice automatically. That is, on the 4-port HWIC, ports 0 and 1 will be set to the same value, and ports 2 and 3 will be set to the same value. On the 8-port network module, ports 0 and 1 will be set to the same value, as will ports 2 and 3, ports 4 and 5, and ports 6 and 7. In these cases, a message will be displayed. The example here shows the message displayed when the line termination on port 0 is changed: `Router(config)# controller e1 0/1/0 Router(config-controller)#line-termination 75-ohm Changing the line termination for ports 0 and 1 to 75`
Step 10	loopback {diagnostic \| local {payload \| line} \| remote {iboc \| esf {payload \| line}}} Example: Router(config-controller)# loopback remote esf line	Sets the loopback method for testing the interface. Options are: •diagnostic loops transmit signal back to receive •local puts the interface into local loopback mode at the payload or line level •remote puts the interface into remote loopback mode through an inband bit oriented code (iboc) or, for T1 only, remote esf, which uses fdl codes to set payload or line levels.
Step 11	cablelength long db-loss-value or cablelength short length Example: Router(config-controller)# cablelength short 133	T1 only. cablelength long attenuates the pulse from the transmitter using pulse equalization and line build-out. This command applies to cables longer than 660 feet. Loss values are: •0db •-7.5db •-15db •-22.5db Default attenuation is 0db. cablelength short sets transmission attenuation for cable lengths of 660 feet or less. Cable lengths can be specified as follows: •110 for cable lengths from 0 to 110 feet •220 for cable lengths from 110 to 220 feet •330 for cable lengths from 220 to 330 feet •440 for cable lengths from 330 to 440 feet •550 for cable lengths from 440 to 550 feet •660 for cable lengths from 550 to 660 feet There is no default cable length.
Step 12	channel group channel-group-number {timeslots range [speed kbps] \| unframed} or pri-group timeslots timeslot-range or tdm-group tdm-group-no timeslots timeslot-range Example: Router(config-controller)# channel group 1 timeslots 1-4	Note This step does not apply to the clear channel 4-port T1/E1 HWIC. Configures the serial WAN on a T1 or E1 interface by specifying channels and their timeslots. For T1, values are as follows: •channel-group-number is from 0 to 23 •timeslots range is from 1 to 24 •Default value of speed in T1 is 64 kbps. Configuration of speed is optional. For E1, values are as follows: •channel-group-number is from 0 to 30 •timeslots range is from 1 to 31 •Default value of speed in E1 is 64 kbps. Configuration of speed is optional. •unframed (E1 only) specifies that all 32 timeslots are to be used for data, and that none are to be used for framing signals. or Configures specified timeslots on T1 or E1 interfaces for PRI for transporting ISDN data. or Configures specified timeslots on T1 or E1 interfaces to create clear chanel groups for time division multiplexing. For the tdm-group configuration to work, it is necessary to configure network-clock-participate for the interface in global configuration mode.
Step 13	national reserve N sa4 sa5 sa6 sa7 sa8 Example: Router(config-controller)# national reserve 0 1 1 1 1 0	E1 only. Sets the 6 required national bits in E1 in the G.751 frame. Default is 1 1 1 1 1 1.
Step 14	crc-threshold value Example: Router(config-controller)# crc-threshold 500	T1 only. Defines a severely errored second by specifying the number of crc errors that must occur in one second to reach the severely errored state. Default is 320.
Step 15	yellow {generation \| detection} Example: Router(config-controller)# no yellow detection	Enables generation and detection of yellow alarms. Default condition is that generation and detection of yellow alarms are enabled. Use the no form of the command to disable yellow alarm detection.
Step 16	bert pattern pattern interval time Example: Router(config-controller)# bert 2^11 interval 1440	Optional. Activates the Bit Error Rate Tester (bert) with the chosen test pattern for a specified duration. Configure bert patterns on T1/E1 HWICs or network module as follows: •When the linecode is AMI, use patterns 2^11, 2^15, or 2^20-QRSS. •When the linecode is b8zs or hdb3, use patterns 2^11, 2^15, 2^20-QRSS, or 2^20-O.153. Note If any other bert pattern is chosen, an error message will appear that lists the supported patterns for the configured linecode. A complete listing of bert patterns is in the Cisco IOS Master Commands List, Release 12.4. interval time is from 1 to 14,400 minutes.
